Transcript of Deforestation
By: Max Ramirez
What is Deforestation?
Deforestation is the act of removing forests and/or stand of trees.
"Examples of deforestation include conversion of forestland to farms, ranches, or urban use."
Deforestation at it's finest.
Regions Affected by Deforestation
Democratic Republic of the Congo
Central America and the Caribbean:
Papua New Guinea
Causes for Deforestation
According to the United Nations Framework Convention on Climate Change (UNFCCC) the overwhelming cause for Deforestation is agriculture.
Subsistence farming is responsible for 48% of deforestation; commercial agriculture is responsible for 32% of deforestation; logging is responsible for 14% of deforestation and fuel wood removals make up 5% of deforestation.
Although experts do not agree on whether industrial logging is an important contributor to global deforestation.
Another cause of Deforestation is population size. We keep growing larger in numbers that we need more land so we remove forests to make space
Affects of Deforestation
Cutting down forests, causes Carbon Dioxide to linger in the atmosphere, and when the Carbon Dioxide accrues, it produces a layer in the atmosphere that traps radiation from the sun. The radiation converts to heat which causes global warming, which is better known as the greenhouse effect.
In deforested areas, there are no trees to transpire water. Which makes it into a much drier area, and reduces the amount of water in soil and groundwater aswell as atmospheric moisture. Flooding, landslides, and erosion are caused in deforested ares because of the reduced soil cohesion, and because of deforested areas, the area becomes sources of surface water runoff, which could cause flash flooding in local areas.
(the variety of life in the world or in a particular habitat or ecosystem.)
Deforestation results into a decline in biodiversity, and known on a global scale is the cause of extinction in many species. Forests support biodiversity, providing habitat for wildlife. Forests foster medicinal conservation, which cutting them down would destroy genetic variations (like crop resistance) irretrievably. Because of deforestation, it is estimated we are losing about 137 animal, plant, and insect species every day, which is the equivalent of 50,000 species a year. It is expected that 90% of predicted extinctions will occur in the next 40 years.
What are they doing to save Forests and Rainforests?
Good question, the Human race has been trying to do many things to help out the forests recover from Deforestation. Including the following:
Reducing emissions (Stop Deforestation)
Payments for conserving forests
Farming (New Equipment)
Monitoring deforestation (Arial View, Changes)
Forest management (Policies to Prevent Deforestation)
Sustainable practices (Need for Lumber)
What can you do?
Easy you can:
Remember the Reduce, Reuse, Recycle statement?
Before you print think to yourself do i really need to print this out? If it's a school paper most teachers will accept neat hand-written work.
If you do need to print, try to use both sides of the paper. If you have a printer that prints on both sides than good. If not than put the paper back in the other way.
Make sure anything you buy (like toilet paper, tissues etc.) comes from recycled resources.
Reuse Envelopes and Paper Bags
Ask your teachers/boss to buy Recycled Paper for work.
Write to Goverment officials to go as paperless as they can.
