The above listed are causes of deforestation which has resulted to destroyed forest habitats through construction of roads, cutting down of trees, drier environments, clearing forests for farming activities, raring of large populations of animals has led to overgrazing and the clearing of forest resources to give ay to mining activities has resulted to loss of forest (Myers, 1992).
in conclusion the causes of forest deforestation are the reason that makes the forests in the world to disappear very fast while the effects is the outcome of the activities that lead to destruction of forest reserves including extensive deforestation, leading to soil erosion and desertification. The destruction of forest is a typical example that can be used to demonstrate the cause and effect concept.
Human activity is not solely responsible for climate change. It can occur due to natural causes as well. Large volumes of sulphur dioxide, ash, water vapor and dust escape into the atmosphere when a volcano erupts. Volcanoes also produce aerosols which reflect solar energy back into space. This cools the atmosphere. However, although volcanoes produce CO2 and greenhouse gases it is minor when compared to what we humans emit into the atmosphere. Changes in the Earth’s orbit and changes to the ocean’s currents are also natural causes that cause climate change.
