A healthy environment is essential for a healthy life. People take the necessary materials from nature and environment for a healthy life. The sustainable use of natural resources and the maintenance of the balance of the environment depend on the survival of animals and plants and the development of mankind. All the elements of this earth (living and inanimate) are an integral part of the world environment. Natural resources, especially water and soil, are essential for the functioning and structure of agricultural production systems and for overall social and environmental sustainability.
Sustainable natural resource conservation is the process of conserving the natural environment through rational use and efficient management and its equivalent resources. Integrated environmental education can provide knowledge that is effective in the sustainable management of natural resources. All human efforts towards development are based on the presence of natural resources. Although the world has been supporting life for thousands of years, it is currently facing serious environmental challenges as a result of human impact and it is a threat to the life support system. This is a potential environmental disaster.
Integrated environmental education can be used as a necessary awareness-raising tool, which indicates and strongly emphasizes the sustainable use of natural resource foundations to protect natural resources for future generations. Lack of awareness of environmental education, greed and careless attitude of the people are threatening the natural resources for their extinction.
Recently, the deterioration of the natural environment has been identified as a serious problem for the survival of all species and for human civilization. Various socio-economic problems such as overpopulation, poverty, illiteracy, inadequate health, lack of public awareness, unplanned use of land, urbanization, industrialization and construction of infrastructure have been identified as obstacles to environmental protection and development of environmental standards. These need to be addressed holistically and holistically with environmental development activities.
As the population grows, so does the pressure on the environment. Natural and climate change disasters such as floods, droughts, cyclones, tidal surges, etc. in Bangladesh, early signs of desertification in the north, salinity in rivers, erosion, rapid deforestation, climate change, climate uncertainty and other environmental problems.
Strategies and management strategies need to be developed that combine both natural resource development efforts and conservation systems. It will improve, maintain and protect the natural environment and its resources for the benefit of all mankind. Natural resources are capable of being destroyed by limited, limited and unstable use and this can be a limiting factor of sustainable development. Some of the natural resources were in the past but may not be in the future as it will depend on the way they are used. So, if they are to be managed in a sustainable manner in a sustainable manner, environmental education is required about the characteristics of natural resources so that they do not become a limited factor in sustainable development.
Communities need to be aware of the problems associated with the use of natural resources, such as advances in engineering and technology. Climate change and global warming have been linked to the use of some natural resources. The use of some natural resources has caused environmental problems due to the waste generated. During the use of natural resources, human activities such as power generation, industrialization and transportation were responsible for the accumulation of greenhouse gases in the atmosphere. Carbon dioxide, methane, nitrous oxide, chlorofluorocarbon gases are being associated with global warming which has caused other environmental problems. These environmental problems can be reduced by harnessing natural resources on a sustainable basis.
Agriculture accounts for about 80% of the total freshwater withdrawals worldwide. Agriculture also contributes to water pollution from nutrient and pesticide run and soil erosion. Without improved efficiency, the amount of water in agriculture worldwide is expected to increase by about 20% by the year 2000. Climate change is already affecting water supply and agriculture with higher incidence and intensity, along with changes in the duration of the monsoon and the melting of snow packs, as well as droughts and floods.
Increasing productivity may help advance food security and the general well-being of producers and rural populations around the world in the future, but sustainable development based on limited natural resources dependent on agriculture will ultimately depend on responsible management of the planet’s natural resources.
Natural resources are things that exist naturally in the natural environment, they are not created by humans. These are soil, water, sunlight, wind, plants, coal etc. Natural resources have been further classified as depleted and essential resources. Wearable resources are those that will be exhausted with limited and uninterrupted use. For example, coal, natural gas, etc., while essential resources are those that cannot be reduced by human consumption, for example, wind power and water power, etc.
As the world’s population grows at an alarming rate, so does the use of natural resources. Thus, these resources should be conserved to maintain the ecological balance and preserve them for future generations. Proper management to prevent the destruction or exploitation of a resource is called conservation.
Nature provides all the necessities for our daily needs. Due to overcrowding and human neglect we have started using our resources excessively. If this continues, we will have no resources for future generations. Wealth Preservation Requirements:
l Supporting life by supporting ecological balance.
l Make sure that future generations will be able to access the assets.
l Protect biodiversity.
l To make sure the human race survives.
The way of preserving natural resources:
l Forest: Planting helps in reducing soil erosion.
l Terracing: Terrace farming helps to control the rapid flow of water which takes away the soil with its flow. It is usually practiced in hilly areas.
l Soil Fertility: Soil fertility is achieved by adding maintenance fertilizers or fertilizers or even through crop rotation.
l Rainwater Harvesting: This is the process of rain water conservation.
l Treatment of industrial wastes: Chemical wastes need to be treated before they are released into the water.
l Dams and reservoirs: Dams help to store and supply water when needed. They also help to produce energy.
l Growing plant: It helps to stop the flow of water and it sinks to the ground by increasing the level of ground water.
3. Sources of energy:
These include coal, bio-natural gas, etc. These are exploited in one form or another every day. Natural gas is commonly used for cooking and coal is the main source of electricity. Petroleum products are used to drive cars. These are being eaten in large quantities every day. So, they are non-renewable as there is an urgent need to conserve energy resources. The steps can help save their biomass by using energy:
l Promoting green technology like solar panels and other renewable sources of energy.
l Reduces excessive exploitation of these non-renewable energy resources. To spread awareness among the people about the need for conservation.
l In Situ: In Situ conservation is said to protect plants and animals in their natural habitat. Such as- National Parks, Wildlife Sanctuaries etc.
l X-situ: Protecting plants and animals outside their natural habitat is called X-situ conservation. These include Seed Bank, Pollen Bank, Botanical Garden, Zoo, Gene Bank etc.
