STOP

How has DEFORESTATION affected the Amazon rainforest?

Madelyn Leonard, p.6

Definition

Deforestation is the action of clearing a wide area of trees to convert the forest to a non-forest use.

Deforestation can involve conversion of forest land to farms, ranches, or urban use.

of Earth's land surface is covered by forests.

Threats

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

Erosion

Without the tree roots to act as a anchor to the soil, erosion can occur and sweep the soil into the rivers.

The crops that people plant often don't have strong enough roots to hold the soil together.

Global Warming

Forests help lessen the amount of carbon dioxide in the air, but when the trees are cut down and burned, they release carbon dioxide into the air.

By having more carbon dioxide in the air, the weather patterns become more extreme, leading to warmer summers and colder winters.

Loss of Species

The forests/rain forests are home to around

10 million different species of animals.

When we cut down the trees, we are destroying the animal's natural habitat. Thousands of species of animals have already become extinct.

In the Amazon that includes the gorilla, the amur leopard and the bonobo.

The Amazon

The Amazon rainforest is one of the largest forests that has been affected

by deforestation.

Biodiversity

One in ten known species in the world lives in the Amazon rainforest:

40,000

plant species

2,200

fish

1,294

birds

427

mammals

428

amphibians

378

reptiles

have been scientifically classified in the region.

Destruction

over

(1.1 million kilometers squared) of the Amazon has been destroyed by forest fires, bulldozers, machines, etc.

Human Causes

Behind deforestation:

Increased greenhouse gasses from burning of fossil fuels.

Fires to purposefully burn down trees.

Changing the land use to farming.

World Wild Life. (2020 May). www.worldwildlife.org/threats/deforestation-and-forest-degredation.

Consequences

With deforestation:

Fire burns the oxygen levels.

When the plants burn, there is no food for the animals and the animals die.

3 Possible Actions

To combat deforestation.

Today our class could donate to www.amazonwatch.org to make an impact.

Planting Trees

HOW IT WILL HELP

Planting trees will help the future, because we are replacing the trees we cut down .

Stop Cutting Trees

Stop cutting trees so we don't have to plant more and to save the soil from errosion.

Don't Set Fires

Don't set fires to begin with.
