THE EFFECT OF DEFORESTATION Oredugba Olawale Olakunle, Mogilna Nataliya, Kostyuchenko Nadiya Sumy State University, Ukraine Nowadays many countries are facing the problem of deforestation. Deforestation is the permanent destruction of indigenous forests and woodlands. Deforestation has resulted in the reduction of indigenous forests to four-fifths of their pre-agricultural area. Indigenous forests now cover 21% of the Earth's land surface. Deforestation occurs for many reasons, but most of them are related to money or to people’s need to provide for their families. The biggest driver of deforestation is agriculture. Logging operations, which provide the world’s wood and paper products, also cut countless trees each year. But not all deforestation is inten tional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees. The top five causes of deforestation are: logging (both legal and illegal), industrialization, agri culture, oil exploitation and human disasters. Deforestation has many negative effects on the environment: The most dramatic impact is a loss of habitat for millions of species. It also often results in damage to the quality of the land as it causes soil erosion. As a result of soil erosion silting of water courses occurs. Deforestation is one of the reasons of desertification. Deforestation also drives climate change and causes global warming. Trees absorb CO2, helping to reduce the amount of carbon in the atmosphere. Carbon is one of the key causes of global warming and reducing these gases will help to slow and stop the greenhouse effect. The other issue is that trees are often cleared and burned. The burning of the wood releases carbon into the atmosphere, giving the double whammy of releasing harmful greenhouse gases, yet reducing the number of trees that would have helped to remove this from the atmosphere. In Nigeria as in most tropical regions of the world, deforestation constitutes a major health, environmental, ecological and socio-economic challenge. The research methodology stresses a mix scale approach involving social research in areas of active and non-active deforestation in Ebony state Nigeria and the descriptive assessment and analysis of t he forest resource exploitation issues, as well as the implication for sustainable forest resource management. Findings indicate that the income status of individuals residing in the areas of active deforestation was lower than those of areas of non -active deforestation. Higher yearly episodes of malaria and the tendency to spend less amount of money for malaria treatment characterized the areas of active deforestation and the inhabitants had higher preference for use of wood fuel and use of forest medicina l herbs for malaria treatment. In the areas of active deforestation, the mosquito night biting/landing rates were considerably higher than those of areas of non-active deforestation. Conservation policies aimed at slowing deforestation will impact malaria and would reduce the increasing incidence of deforestation-dependent malaria epidemics. There are many steps to stop deforestation. The quickest solution to deforestation would be to simply stop cutting down trees. Though deforestation rates have slowed a bit in recent years, financial realities make this unlikely to occur. A more workable solution is to carefully manage forest resources by eliminating clear -cutting to make sure that forest environments remain intact. The cutting that does occur should be b alanced by the planting of enough young trees to replace the older ones felled in any given forest. To plant indigenous trees will be also one of the ways out. Joining one of the man y campaign groups is a positive step that can be taken, however there are other practical things that we can do. Ensuring that all paper is recycled and that paper purchased is recycled means that the demand for virgin material is reduced. We need to use wood sparingly. Many differing groups such as environmental and political parties, governments, consumers, corporations and also those who actually work in the forests should work together to stop deforestation. We need to raise awareness about the potential hazards that will accrue if deforestation continues unabated. If there is nobody to alert the people of the climatic change and prevent deforestation then none would be able to save the planet Earth.
