Plants, the Green Potential
Plants, the Green Potential :
The millions of plants on this earth form the very basis of survival of all other life forms. It was primarily the plant life of several million years ago that generated the oxygen in the atmosphere for our survival. It is held among the botanists that the destruction of one plant species is like extinguishing 30 animal species. There are innumerable plant species that alter their lives in accordance with the environments around them. For example, there are luxuriously growing plants from the deserts to the Tundra of the poles.
The development of vegetation has a range of xerophytic plants of the desert wastes to the abundantly evergreen trees of the tropics. With the human intervention, the vegetation has been affected in several places. Of the total land area of the world, 30 per cent is occupied by the forests. These forests are a fundamental cause for biological activities, biomass and plant nutrition. They also determine the nature and magnitude of the bio-geo-chemical cycles such as the carbon, nitrogen and oxygen cycles. Further, they determine the temperature, rainfall and other climatic elements of the earth.
