EFFECTSEFFECTS
• Deforestation– When trees are cut down and
then reforestation does not occur
– The more the population grows there is a greater need for land and resources so people are cutting down trees to use them for houses
– 50,000 species of plants and animals a year become extinct due to deforestation
– There used to be 14.8 billion acres of forest and now there are only 8 billion
– Deforestation is also one of the causes of global warming

increases so does war– 1970-1999 80% of all
civil conflicts that caused at least 25 deaths occurred in countries in which 60% or more of the population was under the age of 30
– An increase of people causes more shortages of food and land and people fighting over them
