Deforestation

Desertification

Desertification is the degradation of land in arid or semiarid regions caused by climatic changes, human influence, or both.

Effects of deforestation
Effects of Deforestation adversely affect public health

  • Loss of Species:

  • Soil Erosion

  • Life Quality: Soil erosion can also lead to silt entering the lakes, streams, and other water sources. This can decrease local water quality, contributing to poor health in the local population.


What causes desertification
What Causes Desertification? adversely affect public health

  • Overgrazing

  • Destruction of plants in dry regions is causing desertification to occur. People are cutting down tress to use them as a source of fuel. Once all these trees are cut down there is nothing to protect the soil. Therefore, it turns to dust and is blown away by the wind.


The effects of desertification
The Effects Of Desertification adversely affect public health

  • Soil becomes less usable

  • Vegetation is Lacked or Damaged

  • Food Loss

  • Causes Famine
