Deforestation: Facts, Causes Effects

Slide 1: Deforestation: Facts, Causes & Effects. Done by Khalilova E.V., the teacher of English, Lyceum №3 named after A.S. Pushkin

Slide 2:Benefits of Forests. Forests cover 31% of the land area on our planet. They produce vital oxygen and provide homes for people and wildlife. Many of the world’s most threatened and endangered animals live in forests, and 1.6 billion people rely on benefits forests offer, including food, fresh water, clothing, traditional medicine and shelter.

Slide 3: What is Deforestation?

Deforestation is the permanent destruction of forests in order to make the land available for other uses.Deforestation refers to the cutting, clearing, and removal of rainforest or related ecosystems into less bio-diverse ecosystems such as pasture, cropland, or plantations.

Slide 4: Causes of Deforestation. There are many causes of deforestation. The WWF reports that half of the trees illegally removed from forests are used as fuel.

Some other common reasons are:

To make more land available for housing and urbanization

To harvest timber to create commercial items such as paper, furniture and homes

To create ingredients that are highly prized consumer items, such as the oil from palm trees

To create room for cattle ranching

Slide 5:Forms of Deforestation. Deforestation comes in many forms, including fires, clear-cutting for agriculture, ranching and development and degradation due to climate change.

Slide 6: Thousand square miles of forest are lost each year—equivalent to 20 football fields every minute.

Slide 7: Deforestation and climate change. Deforestation is considered to be one of the contributing factors to global climate change.The No. 1 problem caused by deforestation is the impact on the global carbon cycle.Forests act as a carbon sink—soaking up carbon dioxide that would otherwise be free in the atmosphere and contribute to ongoing changes in climate patterns. Deforestation undermines this important carbon sink function. It is estimated that 15% of all greenhouse gas emissions are the result of deforestation.

Slide 8: Other effects of deforestation. Forests are complex ecosystems that affect almost every species on the planet. When they are degraded, it can set off a devastating chain of events both locally and around the world.

Loss of species: Seventy percent of the world’s plants and animals live in forests and are losing their habitats to deforestation.

Water cycle: Trees are important to the water cycle. They absorb rain fall and produce water vapor that is released into the atmosphere.

Soil erosion: Tree roots anchor the soil. Without trees, the soil is free to wash or blow away, which can lead to vegetation growth problems.

Life quality: Soil erosion can also lead to silt entering the lakes, streams and other water sources. This can decrease local water quality and contribute to poor health in populations in the area.

Slide 9: Counteracting deforestation.Many believe that to counter deforestation, people simply need to plant more trees. Though a massive replanting effort would not solve all the problems, but it can help.

Reforestation would facilitate:

Restoring the ecosystem services provided by forests including carbon storage, water cycling and wildlife habitat

Reducing the buildup of carbon dioxide in the atmosphere

Rebuilding wildlife habitats

Slide 10: What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another.Mahatma Gandhi
