Mention two manmade causes of increase …

1. Man-induced Deforestation: Deforestation is the cutting down of trees and plants to make way for any development activity. Mother nature taking out an entire forest is one thing, but man doing it for the use of crop cultivation, fuel, and other consumption, is another. Each day our forests are bulldozed for the prospect of farms and factories. Fuel used for wood and charcoal only adds to the polluted gases in the atmosphere. Our consumer commodities provided by forestry includes paper and lumber. The loss of our forests results in a chain reaction where too much carbon is released into the air, with not enough oxygen to combat it.
2. Fossil Fuels: Pollution whether it is vehicular, electrical or industrial is the main contributor to the global warming. Everyday billions of vehicles release various gases into the atmosphere. This causes earth to warm up and increase its average temperature. Electricity causes pollution in many ways. Over 75% of the electricity worldwide is produced by burning of fossil fuels.
