Global climate change has already had observable effects on the environment. For instance glaciers have shrunk, ice on rivers and lakes is breaking up earlier, lands are deteriorating, plant and animal ranges have shifted and trees are flowering sooner. Carbon emission is considered as the strongest factor for global warming. Removing atmospheric carbon and storing it in the terrestrial biosphere is one of the cost-effective options, to compensate greenhouse gas emissions. Millions of acres of abandoned mine land throughout the world, if restored and converted into vegetative land, would solve global warming and would remediate degraded wastelands. Reclamation of mining wastelands using an integrated-biotechnological approach (IBA) has resulted in the improvement in the physicochemical properties of the soil. The findings presented in this chapter may help the industries to achieve clean development mechanism status through afforestation of degraded lands as per the guidelines of United Nations Framework Convention on Climate Change.
