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)

▪ 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. (Read more)

▪ 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 QualitySoil 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.
