The main factor responsible for the current pace of climate change is attributed to anthropogenic emission of greenhouse gases (GHGs), mainly carbon-dioxide (CO2). So, the aim of reducing carbon sources and increasing the carbon sink can be achieved by protecting the carbon pools. Forests are the largest carbon pool on earth as they hold more than...
