Introduction

"Human activities can impose far-reaching effects on an eco system. There is a potential conflict of interest between production and conservation" Discuss. Introduction: The plants and animals that share the same environment are part of an 'ecosystem'. Most ecosystems are very complex. The ecosystem of a forest includes many different kinds of birds, plants, trees, insects and animals. We rely on our environment for 3 essential natural resources; living plants and animals, materials (such as metals, coal, oil, and gas) and energy. People change their environment to benefit their needs and development purposes. When the environment changes, the ecosystem changes too. Changing the environment for the worse is called 'pollution'. Pollution can slow down the growth rate of plants and animals and can affect human health. In recent years people have realised how harmful changing, and therefore, damaging the environment is. Steps have now been taken to prevent pollution through individuals and industries. Derelict buildings have been made into gardens and playgrounds for children, and conservation projects are protecting areas of land, buildings, animals and plants from harm. This essay looks at various parts of the ecosystem and the environment. It looks at the problems that humans cause such as deforestation, pollution (acid rain, air and river), farming and mining. ...read more.

However, the burning of fossil fuels (coal, oil and gas) emits CO2 from carbon that was absorbed millions of years ago and that has accumulated over very long periods of time. Therefore, burning fossil fuels adds massive additional quantities of CO2 into the atmosphere, resulting in an accumulation of the global warming effect. Humans contribute to CO2 emissions through use of vehicles and power plants. We are now starting to use more public transport to reduce the amount of fossil fuels being burnt. It is also very common nowadays for an average family car to be fitted with a 'catalytic converter' which reduces some of the exhaust emissions. Air can be 'scrubbed' by fine jets of water, which remove most of the dirt; or an electric current can be passed through. This removes most of the dust particles. Global Warming: CO2 (carbon dioxide) is a green house gas. It absorbs heat, which radiates from the earth's surface that would otherwise escape into space. The effects of this is higher tides and water levels due to the melting of ice, which therefore causes more floods in which thousands of homes are destroyed every year. The amount of carbon dioxide in the atmosphere has increased by a quarter over the past 150 years. ...read more.

Conclusion

In Britain, the Wildlife and Countryside Act gives legal protection to many plants and animals. > Commercial farming - The development of farms to produce sought-after goods, e.g. milk farming, deer farming may produce enough material to satisfy the market and so remove the necessity to kill these animals in the wild. > Breeding in zoos - Endangered species may be bred in the protected environment of a zoo and when numbers have been sufficiently increased they may be reintroduced into the wild. > Removal of animals from threatened areas- Organisms in habitats threatened by humans, may be removed and settled in more secure habitats. > Ecological study of threatened habitats - Careful analysis of all natural habitats is essential if they are to be managed in a way that permits conservation of a maximum number of species. > Pollution control - Measures to control pollution such as smo0ke emissions and over-use of pesticides all help to prevent habitat and species destruction. > Recycling - The more material that is recycled, the less need there is to obtain that material from natural sources, e.g. mining. These activities often destroy sensitive habitats, through the dumping of waste which is toxic or the development of roads to transport the products. > Education - It is of great importance to educate people in ways of preventing habitat destruction and encouraging the conservation of organisms. 1 ...read more.
