This would lead to wells drying up. Another factor affecting water supply is climate change. As climate warms up weather patterns are shifting. Some places experience a decrease in rainfall and others see an increase. A decrease in rainfall means there is less water in aquifers and the water table.
EFFECTS OF SOIL EROSION- AND THE ENVIRONMENT JAIRAM RAJPAUL 08/16/14 With an increase in the global population there is an increase for food production which ultimately leads to soil erosion, overgrazing, over cultivation and deforestation. What is soil erosion? Soil erosion occurs when there topsoil from the earth’s surface erodes because of overgrazing, over cultivation, deforestation. The nutrients and microorganisms that found within the soil are no longer able to survive and water cannot penetrate through the soil as it would normally. Soi can be washed away or blown away by wind.

Moreover, rapid mechanical agriculture development resulted in over-cultivation, so that the soil was exhausted. Furthermore, the keen world market completion aggravated the problem. J. Laurence Laughlin said that “the price of the whole crop is determined, not by the markets within this country, but by the world-market”. In fact, most of the US agriculture crop was exported. However, the advancement of agriculture technology also benefited other countries, such as Canada, Argentina and Australia.
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It is the phenomenon of grazing animals in greater numbers that the land can support in the long term. Due to animals consuming more grass than can be produced, the ground becomes sparse leaving the soil exposed to erosion. The livestock should be rotated from pasture to pasture to allow this recovery to take place. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion.
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, leading to wells drying up. Another factor affecting water supply is climate change. As the climate warms from ever increasing greenhouse gas emissions, weather patterns shift.
The changes the environment for the reason that the land that was once used for farming becomes completely unusable. Although this is not the only environmental effect, according to (source 6) greenhouse gases are a major problem when it comes to global warming. Trees help to absorb these greenhouses gases converting them into oxygen, therefore, if there are fewer trees to absorb these gases then this will lead to increased rates of global warming. These changes are all separate when they first occur but once these effects last for
Pollution from new factories filled the air and streams in cities while farmers multiplied the size of their farms in the countryside via the acquisition of virgin tracts of land. Expansion confined animals to small areas that could not support them, causing the extinction of some species. Some of these problems have been identified and resolved in the United States, however in third world and underdeveloped countries these environmental issues are still prevalent. The most prevalent of these problems is the shrinking of the South American rainforest, a major contributor to global warming. The possible effects of global warming include melting of the ice caps, which would cause catastrophic flooding.
