Rainforests are one of the most complicated environments on Earth. They are recognized
worldwide as containing the richest source of plants and animals and are believed to contain
nearly three-quarters of all the varieties of life on Earth. This is remarkable because rainforests
cover only about six per cent of the Earth’s land surface.
Rainforests are the oldest major ecosystem, having survived climate changes for more than one
million years. They provide habitats for more species of plants, animals, insects and birds than
any other environment found on our planet. Scientists estimate that between 60 and 90 per cent
of all species of life are to be found in rain forests. Unfortunately, the widespread destruction of
many of the world’s rainforests has caused a significant decline in the number of plant and
animal species on Earth.
Rainforests influence both our local and global climates. For example, between 50 and 80 per
cent of the moisture in the air above rainforests comes from the rainforest’s treees. If larege areas
of these lush rainforests are cleared, he average rainfall in the area will drop. Eventually, the
area’s climate will get hotter and drier. This process could convert rainforests into a sparse
grassland or desert. Rainforests are als able to absorb over 90 per cent of the rainfall in their
leaves and mosses. By doing this, they are able to slow down water run-off by gradually
releasing the water over time into streams and rivers. This helps to control soil erosion and
flooding.
Rainforests are vital to the Earth in helping to recyle carbon and oxygen. Carbon dioxide (CO2)
is the gas put into the air globally by humans, mainly by the burning of fossil fuels (for example
in cars and factories). Rainforests are able to remove carbon dioxide from the air and return
oxygen in its place. This is why our global rainforests are often called the Earth’s “lungs’.
Rainforests are major producers of the Earth’s oxygen. In fact, scientsists believe that nearly 50
per cent of the Earth’s oxygen is produced by rainforests in the Amazon region alone.
Nearly 40 per cent of the world’s carbo is contained in the trees of the rainforests. As rainforests
are cut down and burned, carbon dioxide is released into the Earth’s atmosphere. Eventually, as
this gas builds up the atmosphere, leading to what scientists call the enhanced greenhouse effect.
To sum up, the role of the rainforests is essential for human life. It creates equilibrium in our
environment and its resources are significant for human beings survival.
