Phytoremediation: an alternative tool towards clean and green environment

Abstract

Wetlands being the most productive and ecologically sensitive and adaptive ecosystems are constantly being challenged with anthropogenic pressures due to their wide variety of services they provide to mankind. The vast expansions of human population and associated activities have put a tremendous amount of pressure on these naturally occurring resources. Uncontrolled discharge of effluents in water from various sources resulted into altered nature of the associated ecosystems giving rise to several health issues and problems. Hence, realising the urgent need of protecting these ecologically fragile ecosystems several adaptive measures have been taken. In this connection, it is found that the available conventional methods are not feasible on various grounds like their cost, their by-products, time frame, etc. Therefore, the use of plants emerged as the alternative and promising tool for safe and sustainable ecosystem supporting life.
