Global Issues: Deforestation

Deforestation
   
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 half the size of England are lost each year. (National Geographic)

This advertisement was created for WWF’s campaign in order to raise awareness on deforestation.

▪ Deforestation Causes

▪ Mining Coal Industry:

   Strip mining clears trees, plants and topsoil. Mining companies scrape away earth and rocks to get to coal buried near the surface. Mountains may be blasted apart to reach thin coal seams within, leaving permanent scars on the landscape.
   In this way, strip mining destroys landscapes, forests and wildlife habitats. It leads to soil erosion and destruction of agricultural land.

▪ Laudering:

   Illegally logged timber in Brazil is being laundered on a massive and growing scale and then sold on to unwitting buyers in the UK, US, Europe and China, Greenpeace claimed.
   "Logging in the Brazilian Amazon is absolutely out of control. The current control system is being used to launder illegal timber," said Marcio Astrini, a campaigner who was part of the two-year investigation. (Read more)

▪ Wildfire Caused by Global Warming

   The effects of global warming on temperature, precipitation levels, and soil moisture are turning many of our forests into kindling during wildfire season.
   Higher spring and summer temperatures and earlier spring snowmelt typically cause soils to be drier for longer, increasing the likelihood of drought and a longer wildfire season, particularly in the western United States.
   These hot, dry conditions also increase the likelihood that, once wildfires are started by lightning strikes or human error, they will be more intense and long-burning.

▪ Effects of Deforestation

▪ Loss of Species:
   Seventy percent of the world’s plants and animals live in forests and are losing their habitats to deforestation, according to National Geographic. Loss of habitat can lead to species extinction. It also has negative consequences for medicinal research and local populations who rely on the animals and plants in the forests for hunting and medicine.



▪ Water Cycle:
   Trees are important to the water cycle. They absorb rain fall and produce water vapor that is released into the atmosphere. Trees also lessen the pollution in water, according to the North Carolina State University, by stopping polluted runoff. In the Amazon, more than half the water in the ecosystem is held within the plants, according to the National Geographic Society.


▪ 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. The WWF states that scientists estimate that a third of the world’s arable land has been lost to deforestation since 1960. After a clear cutting, cash crops like coffee, soy and palm oil are planted. Planting these types of trees can cause further soil erosion because their roots cannot hold onto the soil. "The situation in Haiti compared to the Dominican Republic is a great example of the important role forests play in the water cycle," Daley said. Both countries share the same island, but Haiti has much less forest cover than the Dominican Republic. As a result, Haiti has endured more extreme soil erosion, flooding and landslide issues.


▪ 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.
