Scientists believe that this is caused by some human activities like illegal logging, deforestation, burning of garbage, fumes of factories, and smoke from vehicles, improper deposal of garbage and regular using of insecticides. The greenhouse effect is a vital natural process that prevents all of the sun's heat from simply reflecting back out into space. Continued deforestation will intensify the greenhouse effect, causing global warming.
