WWF: Deforestation Main Page
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. But forests around the world are under threat from deforestation, jeopardizing these benefits. Deforestation comes in many forms, including fires, clear-cutting for agriculture, ranching and development, unsustainable logging for timber, and degradation due to climate change. Forests play a critical role in mitigating climate change because they 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 is a particular concern in tropical rainforests because these forests are home to much of the world’s biodiversity. Related:  DeforestationDeforestation

Illegal logging Illegal logging threatens some of the most valuable forests globally – from the Amazon to the Russian Far East. And yet, for many of the people that live in these forests, illegal logging is a vital source of income - sometimes it is the only way to survive. But at other times it threatens their lives. Increased demand for forests products has brought some financial benefits for poor people living near to forests. But there is also evidence to show that usually, poor communities who are completely dependent on forests lose out to powerful interests, logging companies and migrant workers who reap most of the benefits. How does this happen? US$1 for a villager, US$10 from your wallet For example, a small community in Papua Province, Indonesia, can receive approximately US$11 for a cubic metre of hardwood. As a finished product, waiting to be bought on a furniture shop rack in a EU country or the US, this cubic metre will be worth 10 times that much.

Problem 2: Global Warming Voices of Youth: Deforestation Member since February 8, 2014 1 Post Deforestation is when humans remove forest areas and the land is turned to something other than a forest. Sometimes this is done because humans need the trees or because humans need to use the land as farmland or even to create a city. The video above provided by NASA shows a place in Africa where the forests have been cleared and you can see the dirt coming through. National geographic website says "Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year". The effects of deforestation are many.

Deforestation A deforested area Deforestation is when forests are lost and not replanted. Sometimes deforestation happens when people change the land into farms, ranches and cities. A lot of deforestation is from removal of all the trees from a forest for wood or fuel. The opposite of deforestation is afforestation. Cause of deforestation[change | edit source] Deforestation is the removal of trees for requirements of growing population. Forests have the following functions:- regulation of the water cycleproduction of soilprovide habitat for animalsprovide most of our oxygenmaintain the oxygen and carbon dioxide balance in the atmosphereregulation of temperatureprevent soil erosion There are many reasons for deforestation like logging where people cut down trees for money because they have to feed their families Forests are often planted to protect against natural disasters. Trees are also important for storing carbon. Other websites[change | edit source]

WHAT IS DEFORESTATION? Deforestation Facts, Deforestation Information, Effects of Deforestation Modern-Day Plague Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area, but swaths the size of Panama are lost each and every year. The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation. Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families.The biggest driver of deforestation is agriculture. Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. Not all deforestation is intentional. Deforestation has many negative effects on the environment. Deforestation also drives climate change. Removing trees deprives the forest of portions of its canopy, which blocks the sun’s rays during the day and holds in heat at night.

Problem 1: Deforestation ESchoolToday: Forest Preservation Introduction to forest preservation Environmental activists consider forests as one of the top 5 natural resources on earth. This is rightly so, and today, we shall look at how wonderful our forests are to us, and why we should immediately stop its' destruction. There is more to forests than just a massive collection of trees. It is a natural, complex ecosystem, made up of a wide variety of trees, that support a massive range of life forms. Quiet apart from trees, forests also include the soils that support the trees, the water bodies that run through them and even the atmosphere (air) around them. Forests come in many sizes and forms. It is estimated that two-thirds of the world's forest is currently distributed among 10 countries: (REF: IUCN, International Union for Conservation of Nature) Forests are hugely important for life on earth.

Deforestation The Double Whammy of Deforestation Deforestation by burning, a widespread practice in the world’s tropical rain forests, adversely impacts the trace-gas composition of the atmosphere in two different ways. First, the burning of the tropical forests produces large amounts of carbon dioxide, carbon monoxide, methane, and other trace gases that are products when biomass burns. Second, the tropical forest is an important sink, or repository, for carbon dioxide. Atmospheric carbon dioxide is incorporated into the living biomass via the process of photosynthesis, which in turn produces the oxygen we breathe. The Past Much of the Earth was once covered by trees, but the majority of these were cleared long ago to make way for an ever expanding human population. People have been living in and around tropical rain forests for tens of thousands of years, taking what they needed from the wealth of natural resources available without compromising their environment.

SO WHAT'S BEEN IN THE MEDIA? Natural Disasters - Forest fire Blizzards - Earthquake - Flood - Forest fire - Hurricanes - Tornado - Tsunami - Volcano A forest fire is a natural disaster consisting of a fire which destroys a forested area, and can be a great danger to people who live in forests as well as wildlife. Forest fires are generally started by lightning, but also by human negligence or arson, and can burn thousands of square kilometers. Forest fires, also known as wildfires, vegetation fire, grass fire, brush fire or bush fire, is common in vegetated areas of Australia, South Africa, United States and Canada, where climates are sufficiently moist to allow the growth of trees, but feature extended hot and dry periods. Forest fires are caused by the drying out of branches, leaves and therefore becomes highly flammable. Fires can do weird things including: Crawling - spreads from bush to bush Crown - spread at an incredible pace through the top of the forest. Examples: Oakland Hills firestorm. Back to Main Page.
