The population explosion and affluent consumption have placed an undue and excess burden on the environment. The resources are increasingly exhausted day by day, but the regeneration of resources is constant. So, when the resources are extracted at a rapid pace than its regeneration, then the carrying capacity of the environment reduces. The current environmental crises include two major global issues, namely, global warming and ozone depletion. Global warming is the result of rising temperature globally due to the emission of green house gases, especially, carbon dioxide. The rise in temperature accelerates the melting of polar ice leading to the rise of water level in the sea. This leads to ecological imbalances. Ozone depletion is another major concern that is caused due to the excessive use of chlorofluorocarbon (CFCs) in the air conditioners and refrigerators. As ozone depletes, the possibility of ultra violet radiations penetrating into earth surface increases, posing a threat to the living organisms. The culminated effect of these two accounts for major concern of environmental crisis in the present time.
