3 Deforestation on a human scale results in decline in biodiversity, and on a natural global scale is known to cause the extinction of many species. The removal or destruction of areas of forest cover has resulted in a degraded environment with reduced biodiversity. Forests support biodiversity, providing habitat for wildlife

4 What Causes Deforestation According to the United Nations Framework Convention on Climate Change (UNFCCC) secretariat, the overwhelming direct cause of 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. Other causes of contemporary deforestation may include corruption of government institutions, the inequitable distribution of wealth and power,population growth and overpopulation, and urbanization.Globalization is often viewed as another root cause of deforestation, [ though there are cases in which the impacts of globalization (new flows of labor, capital, commodities, and ideas) have promoted localized forest recovery.

5 If You Did Not Understand… It Basically Means… 1. Overwhelming cause is… Agriculture. 2. Second Cause…Logging 3. May Include CORRUPTION Of Government 4. Reason 4: Overpopulation And Growth. Thatta Is All To Understand

6 Effects Of Deforestation BIODIVERSITY: We are losing 137 plant, animal and insect species every single day due to rainforest deforestation, which equates to 50,000 species a year. Others state that tropical rainforest deforestation is contributing to the ongoing Holocene mass extinction. The known extinction rates from deforestation rates are very low, approximately 1 species per year from mammals and birds which extrapolates to approximately 23,000 species per year for all species.

7 Continued… HYDROLOGICAL: The water cycle is also affected by deforestation. Trees extract groundwater through their roots and release it into the atmosphere. When part of a forest is removed, the trees no longer transpire this water, resulting in a much drier climate. Deforestation reduces the content of water in the soil and groundwater as well as atmospheric moisture. The dry soil leads to lower water intake for the trees to extract. Deforestation reduces soil cohesion, so that erosion, flooding and landslides ensue.

8 How Do You Reduce Deforestation One easy way to combat deforestation is to plant a tree. But you can take it one step further by making sure the choices you make at home, at the store, at work, and on the menu don’t contribute to the problem. Go Paperless [ Do NOT use PAPER] Recycle and use Recycled Objects [ So No Need Cut Down Trees]
