Deforestation

Page 2: Deforestation

Deforestation is the process whereby natural forests are cleared through logging and/or burning, either to use the timber or to replace the area for alternative uses.

These include clearing for farming purposes, ranching and urban use. In these cases, trees are never re-planted.

What is deforestation?

Page 3: Deforestation

Since the industrial age, about half of world's original forests have been destroyed and millions of animals and living things have been endangered.

Despite the improvements in education, information and general awareness of the importance of forests, deforestation has not reduced much, and there are still many more communities and individuals who still destroy forest lands for personal gains.

Trees are cut down (deforestation) for many reasons including

To be used, sold or exported as timber, wood or fuel (charcoal). This is called logging.

To be used for farming purposes (grazing fields for livestock, or large scale farming activities)

To make room for human settlement and urbanization (these include making space for shelter, industries and roads)

To make room for mining.

Why do humans clear forest lands?

Soil erosion destruction:

Soils (and the nutrients in them) are exposed to the sun’s heat. Soil moisture is dried up, nutrients evaporate and bacteria that help break down organic matter are affected. Eventually, rain washes down the soil surfaces and erosion takes place. Soils never get their full potential back.

Effects of deforestation

Water Cycle:Water Cycle: When forests are destroyed, the atmosphere,

water bodies and the water table are all affected. Trees absorb and retain water in their roots. A large part of the water that circulates in the ecosystem of rainforests remains inside the plants. Some of this moisture is transpired into the atmosphere. When this process is broken, the atmosphere and water bodies begin to dry out. The watershed potential is compromised and less water will run through the rivers. Smaller lakes and streams that take water from these larger water bodies dry up.

Climate Change: Plants absorb Carbon Dioxide CO2 (a

greenhouse gas) from the atmosphere and uses it to produce food (carbohydrates, fats, and proteins that make up trees). In return, it gives off Oxygen. Destroying the forests mean CO2 will remain in the atmosphere and in addition, destroyed vegetation will give off more CO2 stored in them as they decompose. This will alter the climate of that region. Cool climates may get a lot hotter and hot places may get a lot cooler.

Loss of Biodiversity: Many wonderful species of plants and

animals have been lost, and many others remain endangered. More than 80% of the world's species remain in the Tropical Rainforest. It is estimated that about 50 to 100 species of animals are being lost each day as a result of destruction of their habitats, and that is a tragedy. Many beautiful creatures, both plants and animals have vanished from the face of the earth.

Carbon Emissions: Healthy

forests help absorb greenhouse gasses and carbon emissions that are caused by human civilization and contribute to global climate change.

Page 13: Deforestation

Without trees, more carbon and greenhouse gasses enter the atmosphere. To make matters worse, trees actually become carbon sources when they are cut, burned, or otherwise removed.

“Tropical forests hold more than 210 gigatons of carbon, and deforestation represents around 15 percent of greenhouse gas emissions,” according to the WWF.

Life Quality: Soil erosion can also lead to silt

entering the lakes, streams, and other water sources.

This can decrease local water quality, contributing to poor health in the local population.

Page 15: Deforestation

All of these factors can have adverse effects on local economies.

Increased flooding, lack of quality water, and inability to produce their own food causes many locals migrate to cities that lack infrastructure for them.

Or, they work on plantations, worsening the deforestation problem and at times being subjected to inhumane working conditions.

1. We should not cut trees rapidly.

2. We should use trees in smaller quantity.

3. Whenever we cut a tree , we should plant

a new tree to make the nature in balance.

4. The government of a state should ensure

that there should be less and less forest

fires and the people living near the area

should be careful.
