this article is based on how natural resources are important for human life and how can we conserve it. This is the need of the hour.
Revitalization Of Natural Ecosystems
Human intervention caused enormous damage to natural ecosystems. Natural ecosystems need to be revived. Therefore, for this year's Environment Day, the United Nations has decided on the central concept of 'revitalization of natural ecosystems'. If the ecosystem is revived, you can regain the lost natural dynamics.
The scope is very large, everything around us is the environment. This is a simple and straightforward definition of the environment. There are mainly two elements around us. One is animate and the other is inanimate. Plants, animals and microorganisms are living things while air, water, soil, light, energy and all other are inanimate things. Inanimate elements have no need of living things; But living things cannot survive without inanimate elements. Ecosystems are formed from this interrelationship between living and non-living things. There are such diverse ecosystems in nature and they are all divided on geographical and climatic conditions. The balance of the environment depends on all these living and non-living elements and ecosystems.
It changes in any of the living and non-living elements and even upset the balance of the environment and ecosystems. Most of the environmental problems that have arisen today are man-made. Atmospheric carbon dioxide levels have risen by 33 percent in recent years, accounting for 72 percent of global warming.
Climate change is accelerating due to global warming. This has led to an increase in cyclones, unseasonal rains and hailstorms. In every part of the world, wet drought in some places and dry drought in other places.
What Human Gained Or Lost
There are 33% forest cover is required for ecological balance; But due to human intervention, only 20% of the country's forest area remains. It also has a large area of sparse forests, with only 8% of the forest area required for wildlife and biodiversity conservation. In the process of development, man rapidly destroyed all natural ecosystems. Human intervention caused enormous damage to natural ecosystems. This is why natural ecosystems need to be revived today. For this reason, the United Nations has decided to revitalize the natural ecosystem for the year 2021 Environment Day.
Natural ecosystems take billions of years to form. This requires patience while reviving them. Natural rejuvenation of the local forest ecosystem cannot be achieved by planting fast-growing exotic trees. For this you need to plant only local native trees. It is also necessary to put pressure on building development projects by destroying the rich forest ecosystem. Because, no natural ecosystem can be revived immediately. Humans have destroyed not only forest ecosystems but also water ecosystems, grassland ecosystems, plateau ecosystems, agricultural ecosystems and many more. There must be sincere efforts to maintain the natural balance by reviving them all. If the natural ecosystem is successfully revived, we will be able to regain the natural beauty what we lost.
What Should We Preserve For Our Ecosystem?
It is estimated that by 2060, about 40 percent of the earth's biodiversity will be lost. While some species, and varieties of low yielding crops have become extinct over time due to human commercial thinking, many are on the verge of extinction. After the agricultural revolution, high yielding varieties, species and hybrids were created. This made the indigenous, local varieties of local crops, fruits and vegetables rare and endangered. Deforestation is also destroying wild varieties of local crops. 2021 is the United Nations' has been declared as International Year of Local Fruits and Vegetables Conservation.
Older varieties of indigenous fruits and vegetables have become extinct and are rapidly disappearing. There are two main reasons for this. Today the market is overrun with exotic fruits and exotic vegetables and another reason is that only hybrid, improved varieties are in high demand in the market. Mango for example, nowadays only Hapus Mango and also Devgad or Ratnagiri Hapus are in demand. Then there is Payari and Mankoor mangoes. So the supply is as per the demand. Mango is the national fruit. There are innumerable varieties of mango in our country; But due to lack of demand, these varieties are not cultivated or nurtured. Once those varieties are destroyed, you cannot recreate them. Coconut Mango, Shepu Mango, Dhekanya Mango varieties are not found even after searching. Even if they are not in demand; But they need to be nurtured. Some hybrid varieties of vegetables are available in the market. For example, Ladyfinger and Gawari. But older, hybrid varieties of these vegetables are rarely found. The taste of these varieties is not in the improved varieties.
Nowadays there is no need to save hybrid seeds. New seeds are brought to market every year; But in some areas the old practice of saving seeds has survived. The method of preserving local seeds in Akole area of Ahmednagar district is also a shame to the modern concept. The work of scientific preservation of seeds of native, indigenous varieties of all types of crops is underway in some agricultural universities. Only when all environmentalists strive and cooperate to maintain the balance of the environment and ecosystems will environmental problems be reduced to some extent.
