Introduction

'The environment is being harmed more by human activity that natural disasters.' Do you agree? The world has changed dramatically in the past fifty years. The industrial age and the technological age have clashed and have greatly influenced the present state of the environment. With the coming of the new age of bioscience and biotechnology, further changes are being made to the world's environment. Issues such as pollution, deforestation and over population have had devastating effects on the environment and most have been because of man's activity rather than natural disasters. Natural disasters are a key factor in the destruction of the environment. Floods and high winds have washed away good topsoil vital for agriculture and drowned wildlife and destroyed their homes. Hurricanes such as Ivan have ravaged Caribbean countries, leaving them to rebuild and replant everything. Volcanic eruptions are main pollutants as the ash and dust that are emitted may be poisonous. Natural disasters cause mass devastation in a few hours unlike human activity and can be seen as overwhelming in comparison to the effects man has on the environment. ...read more.

The introduction of chlorofluorocarbons into the atmosphere has led to the depletion of the ozone layer. The ozone layer filters the harmful rays of the sun and prevents them from entering the earth's atmosphere. Due to the increased amounts of CFC's, there has been thinning and the development of a hole in the earth's ozone. This has increased the incidences of skin cancer in both humans and animals. Another type of emission that is slowly destroying the environment is that of greenhouse gases. These are produced from car exhaust and have led to the excessive heating of the earth and the phenomena known as global warming. Global warming has altered climatic patters and caused more devastating natural disasters that at any time in previous history. It can therefore me concluded that the slow effect of these gases on the environment caused by human activity is not only destructive but makes natural disasters even more vicious that ever. ...read more.

Conclusion

This however had a trying effect on the environment as the chemicals remained in the plants that were sprayed. When eaten by birds and other herbivores, the chemical entered their bodies and building up to toxic levels resulting in the death of both plants and a variety of animals. There is also the race to make foods more nutritional and disease resistant. This is done by altering the genes of the food a process termed genetic engineering the results of which are genetically modified foods. These foods though helpful in poverty stricken countries can lead to mutations in plants and so cause the plants to become toxic or even extinct. Natural disasters are no match to these devastating effects that human activity has on the environment. Natural disasters are mass destructors and leave nationwide damage. When compared to man's activities, which depletes the environment and causes worldwide damage, natural disasters are welcomed. Man's activities such as pollution and deforestation increase the effect natural disaster have by affecting climatic systems. It can therefore be concluded that human activity harms the environment much more than natural disasters ever will. ...read more.

    Deforestation also drives climate change. Forest soils are moist, but without protection from sun-blocking tree cover they quickly dry out. Trees also help perpetuate the water cycle by returning water vapour back into the atmosphere. Without trees to fill these roles, many former forest lands can quickly become barren deserts.

  2. What are the effects of Deforestation?

    Like the carbon cycle, the system's initial source of nitrogen is N2 gas from the atmosphere. When it reaches the soil, this gas must be converted into NO3- before it can be used by plants. This process, called nitrogen fixation, is carried out by microorganisms in the soil that are either symbiotic or nonsymbiotic.
