[12:18.22]Rainforests
[12:20.37]Tropical rainforests can be found in places near the Equator.
[12:25.05]Despite occupying a relatively small area,
[12:28.51]rainforests play an important role in maintaining the world.
[12:33.05]First, tropical rainforests are home
[12:36.04]to a rich, colourful variety of plants, food, birds and animals
[12:42.73]and offer a way of life to many people living in and around the forest.
[12:48.09]Second, rainforests are considered the lungs of the planet.
[12:53.16]They are storing vast quantities of carbon dioxide
[12:56.99]and producing a significant amount of the world's oxygen.
[13:01.94]Third, rainforests can produce 75% of their own rain.
[13:08.11]The humidity of large rainforests contributes to the formation of rainclouds
[13:13.37]that may travel to other countries in need of rain.
[13:17.13]However, rainforests around the world are disappearing at an alarming rate,
[13:22.99]due to our destructive activities.
[13:26.25]We can only hope that the world's governments
[13:28.66]work together to preserve the rainforests
[13:31.93]since they are vital for our existence.
