Describe three human caused factors that can affect the earths climate

Oil spills, green house effect, forest fires

Explanation:

1. Oils spills in the ocean (where oil is released into the ocean or coastal waters, but spills may also occur on land)

2. The green house effect (which affects the amount of heat retained by Earth's atmosphere),

3. Forest fires (the environment burns down and the animals loose there home which also leads to less oxygen getting produced)
