We have a limited amount of natural resources across the globe. As these resources are depleting, it has adverse impacts on climate. Global Warming is one of such an adverse impact commonly talked about. The water resource is depleting very fast & hence water crisis has become a global concern. Air pollution, water pollution, soil pollution are also serious concerns having an adverse impact on climate change. Green technology counteracts these through conservation of resources, reduced emission of greenhouse gases, uses of renewable energy resources & so on. Soil remediation methods and carbon sequestration technology are also such countering techniques. Bio-gas plant helps to mitigate bio-mass waste gas generation & air pollution, while converting it into clean energy & fertilizer product as by-product.
