Earth as a living planet
Posted by suman | | 0 comments
The earth has peculiar characteristics among the planet of the solar system. It consists of biosphere, atmosphere, lithosphere and hydrosphere. Its situation, temperature, rotation and revolution, climate etc. are some of the characteristics of the earth. The sun is at the distance of 15o millions kilometers from the earth. The earth is a large habitat for different creatures. It consists of both terrestrial and aquatic ecosystems. The natural resources like land, river, forest etc. are only in the earth. It has favorable environment for all the living beings. Thus, it is a common habitat of all the creatures. Only the earth is known celestial body with existence of living things. Presence of water and oxygen is regarded as the most important feature to make the earth as living planet. Ozone layer, fertile soil, non-combustible atmosphere, adequate water, self-regulating environmental cycles, and so many other favorable situations have made it a common habitat of various organisms. There are different kinds of creatures on the earth due to different geographical structure and climate. The different birds and animals such as elephant, rhinoceros, tiger, falcon, vulture etc. are found on land whereas fish, crocodile and micro-organisms are found in water and amphibians such as frogs, salamander, etc. are found both on land and in water. The structure and special characteristics of the earth support the life of all the living creatures. The earth is a natural habitat that accommodates all the living creatures. There are different types of animals and other living beings in earth. Human beings are the most intelligent and powerful creature of the earth. About 71 percent of the earth is covered with water. Water is found on the surface and underground level. The portion of water that is in the earth is called hydrosphere. Water is accumulated in the lower part of the earth. There is water in ocean, sea, river, pond etc. Water is needed for growth and development of living beings. Water helps in the germination, growth and development of plants, human beings, animals, birds and other creatures. They require water for their survival. The earth is only the planet in solar system that has water. Sunlight causes water cycle and it causes rainfall from time to time on the surface o the earth. All the components of the earth like land, water, air and forests, animal are inseparable and interrelated to each other. If one of them is destroyed, it affects another.
Strategy of caring for earth

The caring of the earth means to conserve all the physical and biological aspects of the earth in its natural condition. Its aim is to provide an opportunity to continue the life of all the living beings. In order to implement the strategy of the world conservation effectively, for the care of earth and for the initiation of sustainable way of development; an action-plan was formulated in 1980 AD. This document explains the policies of the world natural heritage and sustainable development. Based on the guidelines action, programmes on be designed and implemented for the caring earth. The World conservation Strategy motivates and encourages all to take care of the earth. The programme for conservation of the earth should be conducted at local and national levels. A document containing the strategy for caring the earth was published by the joint effort of IUCN (International Union for Conservation of Nature and Natural Resources), United Nations Environment Programme (UNEP) and World Wildlife Fund(WWF). Different nations, international agencies, non-government organizations have supported and agreed to implement the strategy of caring for earth. Their conservation strategy stresses the various efforts to be made for the conservation of the environment and implement of the quality of the environment. Some of them are biodiversity conservation, application of sustainable development principles, natural resources conservation and so on. Along with these conservation activities the programmes should be conducted for the rehabilitation of the living standard of the people. The caring for earth has stated policies and different programmes for the conservation of the earth. The developmental activities should be intergraded with the conservational programmes to take of the earth. The development activities should include conservation programmes. These programmes will help to take care of the earth. The objective of developmental activities should be the improvement of human beings. But they should not emerge the environmental problems. The developmental activities should contribute the improvement of human life. There should be no destruction of natural resources in the name of the fulfillment of the basic needs. Economic justice in the society helps in the conservation of environment by reducing exploitation of natural resources. Therefore, income generating programmes and trainings should be conducted at local and national level. The gap between the rich and poor should be lowest in income and life style. Conducting development and income generating programmes at local and national levels can reduce the existing gap to some extend. It will make human life sustainable.
The rich countries should reduce their consumption pattern of the resources. Especially, the use of the non-renewable resources such as fossil fuel, natural gas, minerals should be drastically decreased. Alternative programmed will donate for the reduction of non-renewable resources. The renewable resources should be produces adequately to meet the need growing population. It helps in conservation of non-renewable resources. The rich countries should provide financial and technical support to the poor countries for pollution control and improvement of the quality of the environment. The people should understand that the carrying capacity of the earth is limited. It takes time to regenerate such resources in nature. Thus, their development activities should be within the limit of the carrying capacity of the earth.
Caring for earth

The physical features of the earth are different at its various parts. The earth is surrounded by air. It has been a living planet because of the availability of oxygen, water and land. These factors have contributed to the formation of a natural environment. There is also a variation in the natural environment in the earth. Because of the variation of natural environment there is diversity in animals, birds and organisms. The caring for the earth means to conserve all the physical and biological aspects of the earth. Its objective is to provide an opportunity to continue the life of all the living beings. This will take place only if all the elements of sphere either living or non-living are properly protected. The world conservation strategy was formulated in 1980 A.D. It has described the policies related to the conservation of world natural resources and sustainable development. It has helped in making essential basis required to carry out developmental and conservational activities in an integrated way. On this basis, the policy and programmes for caring the earth can be prepared. The world conservation strategy has guided all to be involved in the earth conservation programme. The strategy “Caring for the Earth for sustainable Development” is formulated for the execution of world conservation strategy effectively. A document containing the strategy for caring the earth was published by the joint effort of IUCN (International Union for Conservation of Nature and Natural Resources), United Nations Environment Programme (UNEP) and World Wildlife Fund(WWF). These agencies have emphasized to implement the principles of sustainable development worldwide. The government, international agencies, non-governmental organizations, etc have supported the strategy of caring for earth.
The strategy for caring for the earth has given emphasis to run conversational and developmental activities in the integrated way. The developmental activities of the people should help to bring the improvement in life standard of human beings. But the developmental activities should not bring the negative effect on the status of the earth. This strategy emphasizes the creation of sustainable life. Thus, the caring for the earth is the feeling of “live and let live” and the conservation of all living and nonliving things of atmosphere, lithosphere and hydrosphere is related with biosphere of the earth.
Conservation methods of biodiversity
Posted by suman | | 0 comments
Biodiversity must be conserved for the existing of living creatures. We should have the knowledge of biodiversity found in different regions. Programmes on conservation should be launched after finding the condition of animals, its habitat and situation. Local people should be made acquainted with the knowledge of biodiversity found on their region. They should be made aware about the need and importance of biodiversity. Programmes on conservation should be implemented with an assistance of local organizations and associations. Improvement of local people in such programmes is very important. People should be made acquainted with the knowledge of rules and laws of conservation. So, programmes for creating awareness should be launched. Local organizations and associations should be involved for this purpose. Effective media should be used to make people know about the importance of biodiversity and the methods of using it. Biodiversity should be used in income generation works without deteriorating the present situations. People use plants, animals and natural resources to run their daily life. People should minimize the use and give emphasis on reuse and recycling. This leads to conserve biodiversity. For example sustainable biodiversity, it is very important to develop the spirit of conservation. Biodiversity aspects should be commercialized so that people can be interest in their preservation. Different awareness programme should be disseminated to the grass root level that it can make general public realize the importance of biodiversity conservation. The people should create positive attitude towards the biodiversity. They should not exploit the natural biodiversity to fulfill their present needs. They should feel that biodiversity available at present should be conserved for the future generation. The methods such as reuse and recycle assist in the conservation of the biodiversity. Conservation law assists in the conservation of biodiversity. The community people should be aware of the conservation law. It should be encourage local agencies to conduct conservation programme. The people use natural resources for different purposes. The consumption pattern should be in line with the conservation of biodiversity. While using the raw materials in the industries they should be utilized properly. It reduces the use of the raw materials. The local people should be trained in the proper use of the biodiversity. Their conservation should go together with the income generation activities. The income obtained from the use of local biodiversity needs to be used in the improvement of the living standard of the living standard of the community people.

Importance of biodiversity
Posted by suman | | 0 comments
Plants and vegetation help to conserve the sources of water and watershed. Plants absorb water which helps to keep greenery of land. Plants and vegetation reduce the evaporation process, due to which the water gets collected under the soil. There is a close relationship among biodiversity, water source and watershed. The existence of other becomes impossible if one gets deteriorated. The biodiversity plays an important role for the conservation and promotion of watershed. Biodiversity is the main sources, through which people fulfill their basic necessities. Raw materials are available from bio-diversity so that industrial development is possible. The biological aspects can be produced through the conservation and promotion of bio-diversity. Thus, biodiversity helps in economic development. If one element of the environment is destroyed, whole environment is disturbed. Therefore, biodiversity has great importance in maintaining environmental balance.
Biodiversity

In the earth, there are numerous plants, animals, and organisms. The living beings are dependable to each other and interrelated. They differ with each other in terms of their habitat, life cycle, reproduction etc. The living beings are classified into various categories for the convenience of study. There is a diversity and difference in living beings which are found on the surface of the earth. The biodiversity includes the varieties of existing living beings in per unit area of earth. The types and diversity of different living beings denote the biodiversity. Biodiversity also includes the variation in ecosystem, where organism and gene play an important role. The ecosystem of different places differs due to biodiversity. The ecosystems are habitats that are suitable to different types of organisms and species. Biodiversity is different with the nature of ecosystems. Biodiversity of a location refers to the existence of organisms and species of living beings per square unit. Biodiversity indicates the total of the living heritage of the earth and their status as well as their differences. It also indicates the system and structure of the living beings in the nature. Greek Philosopher Aristotle has identified 500-600 species of animals and plants. Biodiversity can be classified into species, genes and ecosystem. There are various types of ecosystems. Animal and plants have peculiar kind of adaptation. Ecosystem is the habitat of living beings. Living beings adjust in the ecosystem and survive there. Each organism has its own heredity character, which helps them to adapt and survive in their habitat.
The characteristics of the ecological belts of any country determine the kind of biodiversity. Therefore, there is diversity in living beings according to place. Some organism is found in land, some in water and some in atmosphere. There is some vegetation which grows on watersheds and surface of water too. There is a close relationship among the various types of living beings. If their relationship is broken it causes them difficulty to live in. but destruction of any one of the species harms to ecological balance. For instance, the life cycle of vegetation, birds and animals and other living beings is adversely affected due to the destruction of forest. It becomes very difficult to survive under deteriorating situation of ecosystem. Genetic diversity can be measured within a variety of DNA and other techniques. New genetic variation is produced in populations of organisms that can reproduce sexually by recombination and in individuals by gene and chromosome mutations. In each ecosystem, living creatures form a community, interacting with one another and with air, water and soil around them.
APPLICATION OF SUSTAINABLE DEVELOPMENT

Mitigating measures of environmental pollution
Posted by suman | | 0 comments
People's participation or community participation is very much essential for the conservation of environment. different agencies are conducting conservation programmes. It is necessary to encourage local non-government organizations and communities to undertake conservation programmes at their communities. if people are aware about the importance of environment, they will surely try to keep the environment healthy. We should conduct different types of awareness programmes, targeted to illiterate people, by giving them education about the importance of environment, causes and effects of environmental degradation etc. Natural resources such as air, water, land, forest and wildlife are essential for all the living beings. Natural resources are the sources for air, water, food and other necessary things. they need to be used properly without deteriorating their quality. their over-exploitation without their regeneration affects ecosystem and imbalance the environment. Therefore proper use of the natural resources should be proceed in order to conserve the environment. People conduct several development development activities on the environment. The development activities should be conducted without deteriorating the environment. The development activities should be nature friendly. Afforestation is very much important for the conservation of environment. If the afforestation programme is conducted by the active people participation of the people of community that will sustain and get success because they will take the forest as their own forest. Afforestation is a very good way to control pollution and it purifies the environment. we should be responsible for the expansion of the forest area and its protection. we should plant trees in the barren and terrace land. It helps to balance the environment. soil erosion is one of the problems that deteriorates the environment. the use of the chemical fertilizer should be discourage and organic fertilizer should be encourage. In situ and ex-situ conservation programme should be developed and implemented for the conservation of the environment. The ex-situ conservation programme is helpful for breeding new varieties of plants and animals.Mitigating measures of environmental pollution
Sustainable development

The world commission on environment and development or Brundtland commission in 1987 defines sustainable development as:
"sustainable development is a process in which the exploitation of resources, the direction of investment, and the orientation of technological development and institutional change meets the needs of the present generation without compromising the ability of future generations to meet their needs." The development activities that can persists for long time is the sustainable development. The main goal of the sustainable development is to keep a balance among the various aspects of population, environment and development. it is based on the principle of environment-friendly activities, applied without deterioration of natural resources. With the development activities, the needs of the present generation are fulfilled without hampering the needs of the future generation.
The conduction of one activity should not affects other environmental aspects. people wants to produce more yield from the agriculture land they hold. they apply maximum chemical fertilizer, insecticides and pesticides. these chemicals deplete the land, they may be converted into in long run. Another problem is overgrazing that deteriorates pasture. These activities are not friendly to the environment. Non-renewable resources such as minerals, natural oil and gas are limited resources. if such resources are extracted continuously the mines will be empty. It will affect the quality of the environment. the overuse of non-renewable resources causes energy crisis in the future, since these resources might be completely vanished. Alternative sources of energy should be sought. agricultural, industry and tourism should be run with proper planning for the sustainable development. the sustainable development focuses on the use of developed technology that alters the traditional approach of consumption pattern and brings less environmental hazards. it also focuses on the upliftment of living standard of the present generation. while conducting these activities we should not forget the aspiration of the future generation. the practice of of wise-use of the natural resources should be developed among the users. The over exploiatation of the natural resources depletes the quality of the environment. The goal of the development should be for the meeting of the basic needs of the people. But the natural resources should be deteriorated to fulfill the needs and aspirations. The economic development improves living standard of people. the principles of sustainable development give priority to the basic needs. Development works should be launched to meet the long term goals. sustainable development focuses on the decentralization of development activities. If the development activities are decentralized, then the environmental resources will be consumed in a balanced way. It helps to provide the facilities like transportation, communication, education, health services etc. even in the rural areas. It is clear that sustainable development is a must for environmental conservation.
Environmental Degradation and its effects

Effects of Environmental degradation
Due to environmental degradation human as well as all other creatures have to face great problems. Air pollution results in respiratory diseases,air-borne diseases, skin disease, throat and chest infection etc and also melts the snow that causes landslides and floods. water pollution causes various water-borne diseases such as cholera, typhoid, dysentery etc. human activities are the main reasons for the environmental degradation. many new germs grow when a environment is polluted. Due to polluted air, respiratory diseases emerge and water population causes various epidemics. Similarly, sound pollution causes deafness, sleeplessness and even digestive diseases. environmental degradation results scarcity of various items which are necessary to continue our life. The amount of production will declines as the fertility of soil decreases. Similarly drought and excessive rainfall destroy the crops. the raw materials needed for the industries for not obtained and it brings the scarcity of food, clothes and other equipments which are necessary to conduct the daily activities. the main function of ozone layer is to filter the ultraviolet rays of the sun. the ultraviolet rays are very harmful to living organisms. Ozone layer depletion causes global warming and other hazardous results. Global warming is another result of environmental degradation. The temperature of the earth is rising warmer and warmer and due to rise in temperature, the polar icecaps melting and the ice an the colder regions is not thick as it was before. Many species are lost day by day due to various activities of the human beings. the life of the creature Will be in danger if environment goes on deteriorating in the same way. So, to live happy and prosperous life we must conserve our environment.Environmental Degradation and its effects
Interrelationship between Environment, Population and Development

It is obvious that people depend on the environment to get the things whatever they want. They think that environment is an unlimited resources. An increase of population demands more food, more shelter, more services and other facilities. If the population growth is higher, the natural resources will be over used, we should integrate the environment conservation and infrastructure development. As the population increases the use of the environmental resources increases. It forces to initiate more development activities to meet the needs of the people. but the people should not forget to conserve the environment along with the development activities. it is necessary to maintain a balance between population growth, environmental resources and development activities. The relationship of people, environment and development activities needs to be maintained and continued for keeping a healthy environment. development activities should cover the necessities such as balanced food, clean drinking water, health services and security. the principle of sustainable development can be well attainment if the preliminary needs are fulfilled.
A deep-roted relationship between human beings and environment has been established from the past. different natural resources are the backbone of development, which helps for the scientific discovery, evaluation of need theory and for all types of social development. without environment we cannot proceed our livelihood. Natural resources, healthy environment human resources development and economic development after the development of health sector.It is very much important to conduct development activities in different parts of the country for the proper distribution of their benefits. It means development activities should not be center. It is obvious that people depend on the environment to get the things whatever they want. They think that environment is an unlimited resources.

There is a close interrelationship between population, environment and development. Human being depend on the various resources of environment. Human fulfill their basic needs from the environment. They need water, air and food which are obtained from the environment. Unlike the other creature, human are not satisfy only with basic needs. They need different other facilities and materials to make their life comfortable and improve their living standard. People conducts various type of development activities for their benefits and improvement. to conduct the developmental activities the environmental aspects such as land, forest, water and modern technology are used. Development work is incomplete if the environment is not preserved and conserved. The development activities should be conducts for the welfare of human beings without harming or deteriorating the environment. the development activities take place in environment. natural resources available in the environment are used for the development activities. Development works or activities can not be conducted and move forward with natural resources. Therefore, development of the place or nation is not possible without environment. In such away, there is close interrelationship between population, environment and development. These all are modify by using the natural resources according to the wish of people. The environment provides the raw materials required to run the industries. Various aspects of development works are associated with agriculture, industry, health, transportation, security and communication. these are associated with the environment in one or way or another. development programmes should be formulated in the light of conserving various animals, plants, and their diversity. therefore, development activities should integrate conservation programmes.

Natural resources, healthy environment human resources development and economic development after the development of health sector.It is very much important to conduct development activities in different parts of the country for the proper distribution their benefits. It means development activities should not be centered in limited areas. It should cover various parts of the country with a view to distributing resources available in different parts of the country. it also balances the environment. It helps to balance population distribution in the country and it will contribute to keep the environment in balance. Communication, employment, social and cultural development and its various aspects. Thus environment is a common subjects associated with various aspects. we must understand that environment is as important as our life, so conservation of it is a must for the sustainable use of the resources in our development aspects. The role of people in the development process is vital. human beings is the only one cognizant creature in the earth. so, the duty ti protect the environmental components is in our hand. destruction or conservation of natural resources depends upon the activities of human beings. Human beings should plan and conduct the development activities in view of the environment conservation. This shows that development and environment are the two sides of a coin and are both related to population. Hence, environment and development are essential to human beings for the development of human civilization and to live happy and prosperous life. there must be harmonious relationship between population, development and environmental resources. sized in limited areas. It should cover various parts of the country with a view to distributing resources available in different parts of the country. it also balances the environment. It helps to balance population distribution in the country and it will contribute to keep the environment in balance.

The need of Environment
Posted by suman | | 0 comments
Environment is a broad and complex field. The surrounding is also called environment which includes living things, non-living things, and abstract things of the surroundings. The living things includes plants, animals, and microorganisms. non-living things includes air, water, soil, lands, buildings, heat, lights, etc. Abstract aspect of the environment includes culture, festivals, social norms and values etc. Environment consists of all the natural resources and human developed aspects of our surrounding. Every living organism inhabits in the environment. Human beings depend on the environmental resources for the survival and development. The needs of people are fulfilled by the available resources in the environment but not of human beings, the other living creatures needs are also covered or fulfilled by the available of recourse's in the environment. Our life is difficult in the absence of natural resources which is a part of the environment.they should be responsible to keep the environment a healthy place and sustainable habitat for all the living beings. they have several needs and aspirations, which can be met through the development activities. the development activities are always related to the environmental aspects. The environmental resources are used in infrastructure development. If the resources are used haphazardly the living standard of human goes down. If the environmental factors are favorable to human life, we can live healthy life and if the environmental factors are not favorable we human as well as all other living creature will suffer from various obstacle. it means that population, environment and development activities are interrelated to each other. people need a balanced diet, a healthy shelter, health services, entertainment and other facilities for making their life happy and healthy. So, it's our prime duty to conserve the environment to have happy and prosperous life.
Environment includes physical, biological, social, cultural and economic sectors are related to various aspects. The people conduct different development works to fulfill their needs and to arrange facilities. It brings change in present condition. the development and environment have close interrelationship. the natural resources are utilized by running industries. the development activities brings change in the environment. the environment should not be degraded by conducting development works. the development activities should not destroy the environment. But the human poverty is the obstacle for environment conservation. Hence, the development and environment conservation activities must go forward in integrated way. the environmental degradation has an adverse effect on development process. If there is no environment conservation, the development work will have no meaning. Environment is very important for all the living beings. To survive all the living beings depends upon environment. we human are mostly responsible for conservation because due to our carelessness environment is being unhealthy. without clean environment living being can't survive. All the living creature including human, micro-organism and plant are being able to survive due to environment. all the basic needs which are necessary to live a happy and prosperous life. Eco-environment is necessary to live for long lasting.
