We humans in the mad race of economic growth and pursuit of wealth and prosperity have alienated ourselves from our Mother Nature. As a result, we have started facing disastrous consequences. We played dangerously too long with nature. Nature is now bouncing back on us. Destruction and over-exploitation of nature have led to climate change, which in turn poses a fundamental threat to almost all the ecosystems. An ecosystem is a geographic area like forest, lakes, deserts and mountains, where plants, animals, and other living organisms, as well as weather and landscapes, exist together. If one component is adversely affected then whole equilibrium gets disturbed of that ecosystem. This is what’s has happened with our nature and its constituent ecosystems.
