Deforestation Meaning

Deforestation- Is the act of cutting or clearing trees in an area.

Main Issues with Deforestation


Soil erosion destruction- Soil, and the nutrients in them, are exposed to the sun’s heat. The soil is dried up, and the nutrients evaporate.

Loss of Biodiversity- 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 killed each day as a result of the destruction of their habitats.

Water Cycle- Trees help perpetuate the water cycle by returning water vapor back into the atmosphere. Without trees to fill these roles, many forest lands can quickly become deserts.

Negative Effects on the Environment

Negative Effects

Excess Water- The excess water from land cleared of forest becomes runoff water and enters the ocean instead of seeping downward into the soil to recharge aquifers. Aquifer depletion is already becoming a serious problem in certain areas of the planet and as the human population continues to grow so will the demand for fresh water.

Soil Degradation- Deforestation also results in soil degradation. Forests store nutrients that are required for all plant life. In the tropics almost all nutrients are stored in the vegetation because tropical soil has little organic matter and almost no nutrient storage capacity. If tropical forests are cleared for cropland, the land will yield crops for only a few years and when the nutrients are depleted they become waste land.

Main Regions that are affected by Deforestation

Regions that are affected

Regions- Many regions of the world are affected by deforestation: namely in South America (Brazil), Central Africa (Congo), Southeast Asia (Indonesia) and Eastern Europe.

Wildlife that is most affect by Deforestation

Wildlife affected

Jaguars, Hyacinth Macaws, Golden Lion Tamarin, Amazon River Dolphins, Elephants, Koalas, Tigers and Crocodiles.

Can Texas be affected by Deforestation?

Deforestation effects on Texas

Today, scientists estimate that between one-third and one-half of our planet's land surfaces have been transformed by human development.

Specifically, deforestation of Amazonia was found to severely reduce rainfall in the Gulf of Mexico, Texas, and northern Mexico during the spring and summer seasons when water is crucial for agricultural productivity.

Can people be affected by Deforestation?

Deforestation effects on people

Effects on people- 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 people

Who causes Deforestation?

Causes of Deforestation

Deforestation is caused by humans and natural changes on earth.

Humans- They chop wood for the timber, to make houses and homes, to create buildings, to make cities and towns, to create roads and streets, etc.

Natural changes- On the natural side, as the tectonic plates have moved, mountains form and erode, rainfall patterns change, and forests respond to these changes over long periods of time.

Solution for Deforestation

How to Prevent Deforestation

Solutions- Use Recycled Items, Tree Care, Farming Practices, Cut Back on Palm Oil, Use coals for your fireplace, instead of wood, etc.

Deforestation in Brazil rain forest spurs evolution

May 31, 2013 | By Geoffrey Mohan

Deforestation is propeling fast changes in evolution, a study of the Brazilian rain forest suggests. Researchers found that in areas where populations of large-billed, fruit-eating birds, such as toucans, have been driven out because of deforestation, palm trees have evolved to produce smaller and less successful seeds. The Brazilian scientists collected more than 9,000 seeds from 22 palm populations in patches of rain forest that had been fragmented by coffee and sugar cane development during the 1800s.


Google creates 'near-real-time' deforestation tracking tool

February 20, 2014 | By Salvador Rodriguez

Google is bringing awareness to global deforestation with a new website that lets users see how the world's forests have been being cut down since 2000. The Silicon Valley tech giant has partnered with the World Resources Institute and numerous other organizations to launch Global Forest Watch , a visual map website that lets anyone track deforestation around the world Global Forest Watch shows data for deforestation going back to 2000, and it includes numerous analytical features
