Essay on Conservation of Biodiversity: 8 Selected Essays
The fossil records show that since life originated on earth, about four million years ago, the vast majority of species which existed are now extinct, essay about biodiversity. The first ever assault on biodiversity dates back to the inception of human society. It was then within limits since rate of extinction of species was under the rate of speciation.
Any little modification was suitably compensated by inbuilt self-regulatory system of nature. Ever-increasing human population has drastically disturbed the balance between natural rates of speciation and extinction of species.
Perhaps the extraction essay about biodiversity biomass resources such as fuel wood, timber and fodder by rural communities was within the carrying capacity of forests. But now it has crossed this limit in many resource-rich areas of the world Reid et al. The process of biomass extraction has been intensified due to increasing human population and has thus resulted in loss of biodiversity and ultimately in ecological imbalance.
The loss of biodiversity is considered to be the one of the most serious problems which is far more serious than global climatic change essay about biodiversity stratospheric ozone depletion, glacial retreat, etc.
It is increasing with the increase in population. Habitat conversion and destruction are eliminating species at such a frightening pace that extinction of contemporary species, and the system they live in and support, is leading to imbalance of ecosystem such as imbalance of bio-geochemical cycle, energy flow and severe alteration of evolutionary process Ervin, across the globe in general and India in particular.
