The greenhouse effect and global warming.
The greenhouse effect is a natural process and keeps the average global temperature around 17.C. Without it the temperature would be around -18.C. 
Greenhouse gases include (Absorb infrared radiation):
CH4
CO2
H20 
We enhance the greenhouse effect by adding too much CO2 by:
Burning fossil fuels
Deforestation 
Digging over soil
Therefore the average temperature keeps increasing. It this continues the following changes are possible:
Acidification of the ocean
Melting of polar ice caps - causes extinction of some wild plants and animals.
A rise in sea level causing floods
Higher temperatures and less rainfall - some crops won’t grow
Greater rainfall and intense storms in some areas
The life-cycles of insect pests would alter.
