TREES ARE THE LUNGS OF OUR PLANET

If People really want to breathe clean air and live without respiratory problems,they ought to take care of forests.They are known to be the lungs of the Earth since they are a source of oxygen.However,providing people with oxygen is not the only important role trees and forests play in our life.In fact rain forests or jungles that contain the majority of the largest trees in the world, typically 30 meters (98 ft) to 45 meters (148 ft) tall, are one of the vital factors of preserving our planet.

1-Why are rain forests important?

-1/5 of the world's fresh water is found in the Amazon rain-forest.They are also responsible for 28% of the world's oxygen turnover.

-They provide a natural habitat to many plant and animal species and prevent their extinction. Many millions of species of plants, insects and microorganisms are still undiscovered in tropical rain forests. 

-They help stabilize the world's climate.They cause cloud formation, for example, by recycling water vapor.

-They protect against floods, drought,and erosion.

-They are a source of medicines and are branded as "the world's largest pharmacy", as over 1/4 of natural medicines have been discovered there.

-They provide timber as well as animal products such as meat.

-They are interesting touristic destinations to visit by Eco-tourists for the ecosystem services they provide.

-They support tribal people.In fact they provide home to a huge number of uncontacted tribal groups.These tribes are nowadays in danger because of the deforestation.

2-What threatens rain forests?

-Cutting down trees for wood.

- Building roads.

- Acid rain which is an effect of air pollution.

- Illegal hunting.

- Forest fires.

- Logging and clearing forests to grow crops of corn or other lucrative products.

3-What can we do to save them?

- Manage them effectively without endangering rare species of plants and animals.

- Forbid companies to clear large areas of forests and require them to plant new trees after cutting old ones.

- Governments should create large parks where logging and hunting are not allowed.They should forbid buying illegally imported animals and punish offenders severely.

- People shouldn't use wood to make fire.

- Every single person should be thoughtful enough about the products they consume( popcorn for instance )because rain forests are cleared to make room for farms where these products are grown.

- People should organize campaigns to save the trees.
