  1. Rainforests

  2. Basic information • Characterizedbyhighrainfall (rainsover 1500 mm a year) • Rainforests contain up to 70% of all biological species • rainforests produce about 30% of all oxygen • The trees placed dense and there is many different species, and the undergrowth is little bit less.

  3. Funfacts • There is actuallyfourdifferentrainforestareas • Tropicalrainforest, which are mainly located in the low-pressure zone. • Subtropical rainforest, , which is mainly located near the tropics. • The temperate rainforest, which lies mainly in north. • Mountain Rainforest, which is located in tropical and subtropical zones on mountain slopes. • Everyyearresearchersfindnewanimal and plantspecies. Even if they have investigated them for many years.

  4. Future

  5. Future • As can be seen from the pictures, rainforests have decreased significantly only in a small amount of time. • The lower picture is a satellite image from Brazil. First one is from 1975 and second is from 2009. • My guess is that after 50 years, only 1/4 of the rainforest is left if humans don't stop destroying them. • And if I hit it right, it’s going to effect a lot. We will definitely have less oxygen in the air. The Earth also releases more greenhouse gas into the air.
