Sunday, October 21, Deforestation In todays world, the physical demand on this earth has become a potential environmental hazard. Deforestation, one of these physical demands, has been a growing problem for over the last several decades, especially in the Amazon rainforest.
Our debut as major actors on the global stage — actors comparable in influence to the classic roles played by erosion, volcanism, natural selection, and the like- is a much more recent phenomenon.
This dates back at most several thousand years, but has accelerated greatly in scope and influence over the last several centuries. Several international conferences have been held to tackle environmental problems. The need for harnessing science and technology in support of efforts to achieve the goal of environmentally sustainable human development in the Anthropocene was generally recognized at the Johannesburg Summit.
Environmental hazards are contemporary issue in Africa but before I delve into the causes of the problems and some solutions, I would give some definitions and features of environment. I shall also use Nigeria an African Country as a case study because of the limitations of the work.
It is that mechanical aspect that exists to serve human beings. This definition is unfortunate and wrong for it explained environment as something inanimate; something in at that exists solely for human recreation pleasures and needs. The background to this definition includes the anthropological, religious, psychological, economic and philosophical explanations of the origin and nature of the environment.
Environment is also defined as the natural in which people, animals and plants live.

|Environmental Hazards: Deforestation||Submit manuscript at https: The key goal of the journal is to highlight the impact of environmental hazards on human health and the ecosystem at large.|
Uchebu categorized the environment into physical and non-physical. The physical environment includes land Terrestrial Air, Water Acquatic environments and non-physical — cultural and socio- economic environment. The environment therefore functions according to Kankwenda as: This is because the hazards, which are contained in it, are as deep and grave as they are long lasting in its effect to MAN and the eco-system itself.
Nigeria as a nation encompasses multiple climate which requires and sraddles various physiographic units.
The various ecological zones respond differently to the impact of human activities by virtue of their natural stress response capabilities and inherent carry capabilities.
The Sahelian Savanna is highly susceptible to desertification; the Sudan Savanna can barely cope with human pressures emanating from rapidly growing populations, fuel woods, harvesting and cattle grazing.
The Guinea zone is ordinarily subjected to pressures as a natural buffer between the encroaching desert and the forest belt.
The Rain forest belt is under excessive pressure through poor regulation and over-exploitation of forest products and other economic activities that result in clearing of vast area of land.
Compounding this, especially in the Niger Delta area, is the large scale exploration, exploitation and processing activities by the petroleum industry, which have left their impact through crude oil and petroleum product spillages, gas flaring — related problems, land degradation and depletion of farm lands, water pollution and deterioration of critical habitats for fish stock.
Occurrence of soil and gully erosion, especially in the eastern part of Nigeria, flooding in the low lying belt of mangrove and fresh water swamps, and uncontrolled logging with its inherent problems of destruction and loss of bio-diversity have immensely contributed towards further exacerbation of the deteriorating environmental scenario.
The above are the various causes and effects of environmental hazards in Nigeria. But there are major noticeable changes in the environment as a result of human pressure on it.
These include viz 1 Loss of biodiversity resulting in reduced variety of genetic strains, species and ecosystems, depletion and extinction of species etc. The two broad causes of environmental hazards are the industrially caused environmental pollution and the wasteful private consumption by whole population living under modern urban conditions.
Whereas the former evil is done by a very limited number of humanity, the latter is perpetrated by the whole humanity whose greed has been fired by advertising following the industrial age to want to have more and more things and wastes the resources of nature.
Such coercive and institutional measures cannot work for the pollution by the whole citizenry. Rather a change of attitude and action towards environmental sustainability would be based on the voluntary action of individuals.
Because whatever affects and pollutes the environment is also of effect to us. The spirit behind this approach is to posit that environment is actually animate in the sense of being alive. It is therefore wrong to interpret environment as inert or inanimate. Thus, the practical way forward for man to check environmental pollution and hazards according to Chigbo Joseph are viz — Limit consumption of resources to a minimum and devise ways to use waste products in production.Deforestation means large scale cutting of forests which leads to extinction of various species, relocation of wildlife animals, global warming etc.
Have a look at some of the other implication of this brutal act towards nature. Nov 21, · According to the “Awake” magazine, mankind is presently sitting on a time-bomb on account of environmental effects either in form of weaponry and/or pollutions and hazards such as flooding, drought, soil erosion, deforestation, volcanity, earthquakes, radio-chemical hazards etc.
Oct 21, · In todays world, the physical demand on this earth has become a potential environmental hazard. Deforestation, one of these physical demands, has been a growing problem for over the last several decades, especially in the Amazon rainforest. Environmental degradation is the disintegration of the earth or deterioration of the environment through consumption of assets, for example, air, water and soil; the destruction of environments and the eradication of wildlife.
It is characterized as any change or aggravation to nature’s turf seen to be pernicious or undesirable. Environmental degradation is the disintegration of the earth or deterioration of the environment through consumption of assets, for example, air, water and soil; the destruction of environments and the eradication of wildlife.
Environmental issues in Indonesia are associated with the country's high population density and rapid industrialisation, and they are often given a lower priority due to high poverty levels, and an under-resourced governance.
