  • 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. 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
