farmlands‚ grazing lands‚ and forestlands provide many products and recreational areas‚ so it is important to conserve them. Soil conservationists work to ensure the wise use of these soils. Soil erosion Rain water‚ wind‚ and other natural forces gradually wear away the soil. This process‚ called erosion‚ normally occurs very slowly. But people have greatly increased the

Some of the environmental problems are pollution‚ soil erosion leading to floods‚ salt deserts and sea recedes‚ desertification‚ landslides‚ change of river directions‚ extinction of species‚ and vulnerable ecosystem in place of more complex and stable ecosystems‚ depletion of natural resources‚ waste accumulation

Furthermore‚ high rates of degradation might have increased the sediment load along the catchment area. Generally‚ excessive sediment deposition in earthen dams reduces

only looked at random rocks from the Site. In regards to pebble size there really seems to be no correlation at all as the sites go on‚ with the figures dropping at site 3 only to rise again at Sites 3 and 4. Normally I would expect that due to erosion‚ the size of the pebbles would decrease along the course of the river. A reason for not seeing this could be due to the fact that in the weeks leading up to our fieldwork we experienced a lot of rain. This would have lead to a greater discharge in

you see of human impact on erosion? Humans are also impacting erosion by: the many recreational activities along the beach (e.g. horse riding and four-wheel driving places on large dune areas.)‚ the rising population of Cronulla’s population and the doubled amount of people visiting the Cronulla Coast during the holidays. These factors place pressure upon the infrastructure and coastal environment‚ which can make large dune areas and beaches more exposed to erosion. Are humans impacting

Threatened habitats are those that are in danger of being destroyed for reasons such as deforestation‚ pollution‚ urbanisation‚ natural disasters‚ increasing temperatures and erosion. Habitat destruction is happening all over the world. Tropical rainforests in Central and South America and in Southeast Asia and parts of Australia are being threatened. Rainforests now occupy less than half of the land that they did 100 years

One is loss of soil fertility through depletion of plant nutrients in topsoil. The other harmful effect occurs when eroded soil ends up as sediment in nearby surface waters‚ where it can pollute

The three key geographical processes that shape the coastal environment are erosion‚ transportation and deposition. The key issues relating to coastal management at Cronulla beach are Pollution‚ Tourism‚ Introduced Plants and Population Growth. Pollution is one main key issue at Cronulla beach because people are littering they

MY ROLE IN PRESERVING NATURAL RESOURCES Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water‚ and air‚ as well as a living organism such as a fish‚ or it may exist in an alternate form which must be processed to obtain the resource such as metal ores‚ oil‚ and most forms of energy
