Deforestation & Sustainability

  1. 1. Deforestation &SustainabilityAya Hackett
  2. 2. What is deforestation???? Cutting down, burning, and destroying forests It is practiced to make way for cattle raising and agriculture, especially in the tropical rainforests of South American and Southeast Asia, but also in parts of western Europe and North America It is occurring at a rapid pace and if it continues, rain forests will disappear by the year 2100 and this would include more than half of the animal and plant species on the planet
  3. 3. The importance of trees They absorb the gas from the air and then replenish the air with oxygen More trees means better air They help perpetuate the water cycle by returning water vapor into the atmosphere Forests help prevent an increase in global warming by serving as carbon sinks---areas that trap and store carbon dioxide Help to protect coastal regions, control avalanches and desertification, stabilize sand dunes, and prevent soil erosion and degradation
  4. 4. Negative Effects Loss of habitat for millions of species 70% of Earth’s land animals and plants live in the forests and they can not survive if they’re homes are destroyed Climate changes Threatens the existence of every living thing on the planet
  5. 5. What is this doing to our world? •Nearly 40 million acres of natural rain forests weredestroyed per year during the 1990s •From 1990-1995, twice the size of Italy had vanished•70% of Earth’s land animalsand plants live in forests, and many can’t survive if their homes are destroyed
  6. 6. Home to many animals…
  7. 7. What are the reasonsbehind these actions?
  8. 8. This happens because… Most of the reasons relate to money or peoples needs to provide for their families Agriculture  Practice of farming  Growing crops To make areas of residence or industry Logging operations  Provide wood and paper products Non intentional  Wildfires  Subsequent overgrazing
  9. 9. LETS MAKE A CHANGE!!
  10. 10. Taking Action! •Reforestation •Recycling items such asbooks, toilet paper, shopping bags •Farmers rotate crops•Cut mature trees & don’t cut the baby trees•Instead of firewood use coals to heat up fireplaces
