Causes of Deforestation Logging logging industry is fueled by the need for disposable products. eg. McDonald’s needs 800 square miles of trees to make the amount of paper they need for a year’s supply of packaging. eg.British Columbia Manufacture 7,500,500 pairs of chopsticks a DAY!!

Other causes Acid rain and the building of dams have their share of harmful effects. The race to produce cash crops Urban development Catastrophic wildfires in dry areas Forest degradation Slash-and-burn techniques by farmers eg.Brazil, Indonesia

Effects of Deforestation Atmospheric pollution Wildlife Deforestation causes the destruction of the habitats of wildlife animals. eg.extinction endangered species Hydrologic cycle water resources The presence or absence of trees affect the quantity of water. Flood

What can we do to help? We can adopt a “zero waste” frame in our everyday-lives. We can reuse/reduce things eg.paper cans boxes

Did you know? Every ton of recycled paper saves approximately 17 trees. It is equivalent to 4,100 kilo watt hours of electricity. Enough energy to heat the average home for 6 months!!
