Introduction

By Arran Roberts Contents Page Title 2 ..........................................................Contents 3..........................................................Loss Of Habitat 5...........................................................Human Activities 7............................................................Solutions Loss of Habitat The amount of land available for animals and plants is reduced by Man's land use, mainly activities such as quarrying, building, farming and dumping waste. Quarrying is a major threat to plants which grow specifically in rocky areas, such as yellow larkspur and American Hart's-Tongue Fern. Plants of this nature are becoming more difficult to find as more quarries appear. (Lakeside daisy threatened by limestone quarrying) Building is a large cause of loss of habitat, towns and cities are outwardly expanding and more land is being used for housing and other large scale building projects such as shopping malls and new roads. Draining of swamps and wetlands and deforestation are also greatly contributed to by building. Loss of habitat and habitat fragmentation are areas of major concern in species conservation, building often results in large areas of habitat being broken up into a series of smaller areas, each of which will support fewer species. ...read more.

Biodegradable waste that is dumped causes a huge problem by producing the flammable gas methane which contributes to global warming. Human Activities Human activities pollute air, water and land in different ways. * Oil spills are becoming a large scale problem, causing devastating effects to marine wildlife. The oil is almost impossible to clean up, spreading over large areas very quickly. Even solutions designed to dissolve the oil can cause an imbalance in the ocean environment. Much water pollution is also caused by sewage and fertilizers seeping into water and starting the process of eutrophication by encouraging the growth of aquatic plants and algae. This process quickly blocks waterways, uses up oxygen and blocks light to deeper water. When this occurs, it kills aquatic organisms in large numbers which leads to disruptions in the food chain. Many industrial and power plants use rivers, streams and lakes to dispose of waste heat. The introduction of hotter water can lead to thermal pollution. ...read more.

Conclusion

Changes of even a few degrees will affect the whole planet through changes in the climate. Acid Rain is caused by emissions from industries which burn fossil fuels. Sulphur dioxide Solutions * Many Conservationist organizations are finding ways to minimise and combat the negative effects that Man is having on the environment. Oil pollution is a growing problem being addressed by Greenpeace, in protest to drilling for oil and by continuing to combat the effects of oil spills. * The use of compost in agriculture is a way of maintaining or restoring the quality of soils because of the properties of the organic matter contained in the compost. It is a valuable method of tackling organic matter depletion and soil erosion in southern europe as well as in areas continuously used in arable production where organic matter levels are decreasing. * The Countryside and Rights of Way Act was passed on 30th November 2000. This legislation puts into place additional safeguards for the most precious wildlife habitats and endangered species. * Strict guidelines have been set to reduce emissions contributing to global warming and to increase recycling in Britain. ?? ?? ?? ?? 2 ...read more.

    Balance of Food Production and Conservation

    4 star(s)

    now largely been replaced with biodegradable insecticides such as carbamates and pyrethroids. Bioaccumulation (or Biomagnification). This refers to the built-up of a chemical through a food chain. DDT is not soluble in water and is not excreted easily, so it remains in the fat tissue of animals.

  2. Global Warming Essay

    Only land-based temperature stations show a warming trend, and these stations do not cover the entire globe, are often contaminated by heat generated by nearby urban development, and are subject to human error. Global climate computer models are too crude to predict future climate changes.

  1. Rain forests.

    Large blocks of forest also occur in Indonesia, Malaysia, and the Philippines. A single family of trees, the dipterocarps, forms a dominant part of the Asian rain forest canopy. About 380 species of dipterocarps grow in these forests. Dipterocarp trees produce valuable wood and resins.

  2. Soil erosion

    Dryland salinity occurs when native vegetation is cleared. As a result of this the exclusion of water by deep-rooted shrubs and trees is decreased, and the level of groundwater rises, which makes the dissolved salts rise closer to the surface.

  1. Estimating the population of non-grass plants on the school fields.

    I am expecting the plants their to have a number of adaptations the will have them survive. This will be vital because without this the plants their would not survive because they would get too much competition from other, better adapted plants and this will force the extinction of the less adapted plants.

  2. An Investigation into the water quality of the River Banwell in

    Now that humans effect the environment on a large scale, these processes include farming, harvesting trees, construction work and disposal of solid wastes. Run off is a process, which is a non-point source. Chemicals maybe bound to soil particles, which are soluble in water.

  1. Human activities can impose far-reaching effects on the environment

    Artificial fertilisers such as ammonium sulphate contain no organic matter and are applied as powders that, being soluble, can easily leach through the soil before plant roots can absorb them. Plants that might compete with the crop are removed or killed by herbicides.

  2. Bradfield Woods as an example of a woodland habitat.

    - some fauna are overwintering in sites that are protected and it is not as dry and hot as the summer so less chance of losing control of the fire. Downsides * Damage to fauna such as reptiles and molluscs also under intense heat there could be adverse ramifications on the soil, moss and lichen cover (may be destroyed.)
