    -Forests are wind-breaker, when they are destroyed it gives way for wind adverse effect.

    -It enhances soil erosion which destruction to farmland and buildings.

    -When forests are destroyed, it increases the concentration of carbon (iv) oxide in atmosphere which in turn depletes the ozone layer and also cause greenhouse effect.

    -The large concentration of carbon (iv) oxide in the atmosphere causes what is known as” global warming”

    -It exposes the soil intense evaporation of soil water and nutrients.

    -It can lead to extinction of some species of plants

    -It may lead migration and extinction of arboreal animals.

    Ways Controlling Deforestation

    -By afforestation programme (planting of trees where they have not existed before)

    -By reforestation-This is the process of replanting trees where they were originally present

    -Use of alternative source or heat

    -Establishment of wild-life park and game reserves.

    -Adoption of modern methods of cattle rearing.


    Government Regulations against Deforestation.

    -Restriction of logging and implementation of a compulsory tree planting programme for all loggers.

    -Increase charges and conviction against indiscriminate logging.

    -Public authorities should impose regulative instruments based on a “command and control” approach

    -Government should have forests areas protected by law.
