why are rainforests important?

Question

im doing a project and cant think why they,re important

Answer 1

1. because they act as 'Carbon sinks' and absorb the carbon dioxide that we produce by running our cars and factories and turns it into oxygen for us to breathe.
Rainforests are huge and absorb a lot of this carbon dioxide, this slows down global warming.

2. There are many species of plants and animals that live in the rainforests only. If the forrests were not there, they would become extinct.

3. There are many tribes of people who live in the rainforest. If we cut them down their way of life would dissapear

4. Some of the plants and animals contain compounds that can be used in medicines. There could be cures for various diseases in the rainforest plants that we don't yet know about.

5. In places where the trees have been cut down the soil looses its fertility after a couple of years and becomes useless for farming. (this is called soil errosion)

Answer 2

Rainforests are important to the global ecosystem. Rainforests:
provide a home to many plants and animals;
help stabilize the world's climate;
protect against flood, drought, and erosion;
are a source for medicines and foods;
support tribal people; and
are an interesting place to visit

Rainforests are very important places because they directly benefit the health of our planet. They act as giant lungs for the Earth by absorbing large amounts of carbon dioxide and producing oxygen in exchange. Rainforests also provide us with many foods, raw materials and medicines.

Despite their importance, rainforests only cover 6% of the Earth's surface. But this 6% is home to 50% of all the animal and plant species on Earth. Such a rich diversity of species is rare and is the main reason for rainforest importance.

Every year about 20 million hectares of rainforest are destroyed worldwide. They are logged for timber and cleared to plant crops and graze cattle. Most of the world's remaining rainforests are in developing nations and the financial return on timber and farming is crucial for survival of people in those nations and takes precedence over rainforest conservation. As a result, destruction continues at an alarming rate.

Over three-quarters of Australia's rainforests have been destroyed since European colonisation. Only a series of fragmented pockets across northern Australia and down the east coast to Tasmania are left. While some of these areas are threatened by burning, agriculture, weed invasion, mining, logging, road building and real estate development, many of them are protected in state forests, national parks or World Heritage reserves.

Australia's rainforests have attracted international and scientific interest because they are home to an unusually high number of animals and plants that are found nowhere else in the world. Furthermore, they contain surviving Gondwanan vegetation, providing us with clues to the origins and evolution of much of the plant life we see in the world today. In addition to this, Australia's comparative wealth means that we are expected to have high conservation standards.

Since Australia is one of the few places in the developed world where rainforests are available for public enjoyment, global conservation and research, we have a special responsibility to take care of our rainforests and their biodiversity.

Answer 3

confident! the greater wood we've on the earth the better it is for us human! they do away with our waste product ( Co2) and convey what we could desire to stay ! Thats how the have been given the nickname the lung of the earth it is authentic! scaling down rainforests is undesirable and could give up! no longer basically do they kill flora and fauna while they do away with wood they're taking some thing that took years to advance away! :)

Answer 4

Because rain forests like all plants, live on water and
photosynthesis which is how they breath, absorbing
carbon dioxide and exhaling oxygen. In other words
the rain forests are a natural filter for the air we breath.

Answer 5

I think it would be best if you do the research yourself. Like in the library or on the internet. Look at these kind people, they're finding them for you.
Anyway, you can look at here

Answer 6

What Bad Shopper failed to mention was that the rain forests also produce most of the oxygen in our atmosphere. Without them we would all suffocate!

Answer 7

the mass amounts of trees create mass amounts of oxygen that even tho it seems unlikely helps benefit all the way across the world

Answer 8

because tree take the carbon dioxide from the air

Answer 9

They produce some beautiful wood.

Answer 10

they give us oxygen
