To summarize what this article talked about it was a study done on the effects of soil degradation and the effects on the vegetation in areas around watering points and normal grazing lands. The study showed that in these ecosystems the overgrazing reduced the ecosystem diversity of plants in poor soils. It also talked about how overgrazing around certain areas can not only destroy the soil but it can also cause the destruction of certain types of species. Overgrazing differs in all areas of the world but it still has a common problem which is that when there is overgrazing no matter what type of environment you are in that environment will be
Deforestation is when trees and other vegetation is being removed converting the forest to another land use, this exposed the soil and often leads to erosion and loss of soil fertility. The valuable nutrients of the soil are being washed away by erosion. To prevent this, we need to stop cutting down trees to create so many buildings, business owners should try to find established dwellings to put their business on. Deforestation also poses a threat to the food chain. These three major causes of soil erosion can be prevented and it will benefit everyone as a whole by creating a sustainable society for our environment.
When there is rain the forests holds a lot of rainfall to the soil through roots of plants. The water then sinks deeper in the ground and replenishes the supply of the water table. If there was the removal of these forests then water from rain would flow simply through the soil surface and not be retained. Another effect may be the water from rain will not stay in the soil at all and the process of evaporation would immediately set in therefore not replenishing water table. This would lead to wells drying up.
2. Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = Lichens need nutrients from the air and water to grow, but humans pollute water with chemicals and air with smoke which can effects there growth. Action affecting Trees = Humans are cutting down trees which is leading them to extinction. Action affecting Flowers = Humans are destroying flowers and plants by destroying the land their on by building buildings and growing crops.
They were masters of restoring nutrients to the ground and producing a great deal of food from their soils. Mayan peasants would slash and burn the rainforest and then wait for the ashy nutrients to go deep into the soil before they would farm. When farmers let the land rest, they are trying to make it fallow (fallow means the land was well rested and nutrient rich). These farmers knew that over-farming could ruin the soil and make it impossible to grow on again. When scientists look at dirt today, they can tell a lot about what happened in the past.
However the trees they cut down were put to use in firewood and fuel for cooking. Other clearances of these deciduous woodlands included for the growth of crops. The land was also used for agriculture and sheep grazing which starts to create a biodiversity. However this damaged the soil but allowed heather to grow and dominate the vegetation that was growing prior to disturbance. Moorland areas were thickly forested.
This study is about the European buckthorn (Rhamnus cathartica, L.), which is an invasive shrub to the woodlands of northeastern Illinois. The European buckthorn is detrimental to the environment because the shrub alters the soil properties where it resides, which forces the natural plant inhabitants of northeastern Illinois to adapt to the sudden change in soil properties. Due to the changes in soil properties, many of the natural plant inhabitants die from the high amounts of nitrogen and carbon the European buckthorn puts into the soil. This study was done mainly outside the lab in the woodlands of northeastern Illinois at three different sites, the Lake Avenue Woods, the East Woods in Morton Arboretum, and the Mary Mix McDonald Woods. The
Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = Lichens depend on air and water for nutrients which is affected by things such as air travel and exhaust fumes. Action affecting Trees = People cutting down trees for useable items is one main way that leads to extinction. Action affecting Flowers = People are clearing off land in order to plant crops and trees Action affecting Bees = There is intensive farming being done all around the world to keep up with the supply and demand of food. As a result this eliminate food that bees pollinate from.
The water is not easily absorbed into the clay because it is harder for the water to enter the pores. Soil type and texture are very important to farmers. Too little water in the soil may cause plants to wilt and die. Too much water in the soil can disrupt a plant's ability to take in oxygen. Based on your data, which type of soil do you think is best for agriculture?
Another big effect of deforestation is the fact that it causes soil erosion. It is estimated that 15,000 acres of topsoil are washed away each year. Which lowers the productivity of the land so it can't be used for growing crops or anything. In 1999 the government of Haiti tried to limit this deforestation, by developing a 15-year Environment Action plan, this plan proposed to by trying to develop an alternative fuel source. The plan is failing due to political instability and lack of
