need of environment conservation
Answers
Answer:
For healthy living: To have a healthy life one needs fresh air (free of pollution), clean water supply and tidy surroundings. If air and water are polluted and surroundings are filthy, then we are prone to fatal health disorders. So we need to safeguard the environment in terms of pollution and disposal of garbage.
Better breath: All living things breathe air for survival. The air mostly composes of nitrogen, oxygen, carbon dioxide and other gases. Of them, oxygen is the key for the body as it helps in the generation of energy from the food consumed with the help of mitochondria. So fresh air is an important component in the importance of the environment which has to be kept pollution free.
Better water: Water comprises nearly 80% of total body mass. It is the medium for all the reaction and physiological processes in the body. If the very water is contaminated by filth or toxins or even disease-causing microbes like bacteria, then that water is a great risk to drink.
Better rainfall: Rainfall is one of the steps of the water cycle on the earth. Without rainfall, there will be no water on the earth (other than sea water which is unfit to drink). This rainfall depends on trees and green vegetation around to shower as the clouds need to be cooled to form droplets. The presence of plants, trees and greenery is essential in the environment for rainfall, fresh air and water.
Better soil: Soil is the other components of the environment. The soil is useful for the growth of plants which are again a source of food to the animals around. This soil top layer is suitable for plant growth and seed germination. Further, it is a great natural resource for many medicines, metals, chemicals, etc. So we need to conserve soil for a better environment.
Biological diversity, or biodiversity, is the scientific term for the variety of life on Earth. It refers not just to species but also to ecosystems and differences in genes within a single species. Everywhere on the planet, species live together and depend on one another. Every living thing, including man, is involved in these complex networks of interdependent relationships, which are called ecosystems.
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies. It's that simple: we could not live without these “ecosystem services”. They are what we call our natural capital.
Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive. But the extinction of a species may have unforeseen impacts, sometimes snowballing into the destruction of entire ecosystems.
European diversity is unique, but the loss of biodiversity has accelerated to an unprecedented level in Europe and worldwide. It has been estimated that the current global extinction rate is 100 to 1000 times higher than the natural rate. In Europe some 42% of European mammals are endangered, together with 15% of birds and 45% of butterflies and reptiles. To list just a few examples, the Arctic fox, the Iberian lynx and the red squirrel are all under serious threat.
