This problem, if left untreated, could also pose a serious threat to the food chain. Over cultivation occurs when farmers or agriculturalists disturb the soil around crops too much. It is the practice of repeatedly cultivating and growing crops more rapidly than the soil can regenerate, leading to a decline in soil quality and productivity. There is a certain amount of cultivation that is necessary to remove weeds and grasses that are not part of the cash crop. Too much cultivation, however, can have the opposite effect desired, injuring the plants it is supposed to nourish.
Although alien species sometimes find new environment a good help, but then, it becomes an invasive species that is thriving, always spreading out, and of course, cutting the amount of native species by predation or another challenge for room or hunger.” In today society, native plants and any wildlife environment in the United States has become the most problem they are facing right now. Native plants occur in North America before European settlement. However, exotic plants are not really found in North America or you may think it would be in a specific region, like North Carolina. But, in North Carolina, it has a lot of exotic plants around that area and other places that’s connected like Asia conditions and everything is alike with the climates. (Wright.R.T, Boorse.D.F.
The removal of crops to feed families and build on the land where the crops were. Deforestation for fuel and construction materials. Inappropriate irrigation practices that lead to high salinity levels which renders the soil infertile. These are intensified by other factors draught depletes vegetation cover. Climatic shifts increases the frequency and intensity of draughts.
What is more, lower yield in less-developed countries leads to ‘yield gap’ in agricultural production (Godfray, 2010). Farmers in developing countries do not master the advanced technical knowledge and skills which can increase food productivity (Godfray, 2010). Also there is not sufficient investment in agricultural area in these countries (Godfray, 2010). So proper measures must be taken to deal with these serious problems. First of all, one part of solutions is strengthening the research in agricultural area (Godfray, 2010).
* Impacts on Agriculture The region’s economy depends on crops; the majority of the Great Plains is used for agriculture. With temperatures increasing, extreme heat, and droughts becoming more frequent, the aptness for certain Great Plains’ crops will change. Livestock will also be put under heat stress and are more at risk for disease. Poor agricultural land management combined with drought can also cause many disastrous events, for example the Dust Bowl of the 1930s. With expected warming temperatures and constant burdens on water and land resources, negative impacts will certainly affect the agriculture.
Due to the reactivity of acid rain, the cell processes of plants are disrupted, and the cells die or become unable to function properly. Although this greatly damages ecosystems, this environmental issue brings concern to society. Today, with our growing population of more than 7 billion, humans have become hugely dependant on agriculture. As such, acid rain has the potential to damage crops extensively, and thus, damage society as well through shortage of food or even famine. In addition, in countries that depend on the production of agricultural goods like Canada, the effects of acid rain can be tremendous.
Both nitrogen and phosphorus are essential nutrients for plants and are therefore present in most fertilizers in addition to being present in agricultural and municipal waste products. As a result, the movement of large amounts of fertilizers around the planet can also mean the movement of excessive nutrients from one place to another. Typically, some of the fertilizer used on a farm does not stay there but moves downhill where it can get into a downstream aquatic ecosystem-a river, lake, or bay. Concentrations of excess nutrients in these bodies of water cause the patches of algae to expand prolifically.
We are finding out now that this is not always the case. In this paper we will examine the causes and effects of two serious environmental catastrophes, one affecting ecosystems in more localized areas called invasive species, and another affecting the entire planet called Global Climate Change. First thing, invasive species. Invasive species are non-native species that are introduced to a foreign area, in which the introduced species has no natural predators to control their growth. In result the introduced species starts reproducing and slowly begins to take over, becoming a nuisance to the environment; and with nothing preying on the new species the invasive species continues to grow.
This inorganic fertilizer gives all the nutrients the plant needs to grow which causes the plant to grow more rapidly and produces the fruits and vegetables quickly. Even though this is less time consuming and less costly, it now has toxins within the fruit or vegetable. When the plant has reached maturity, it is vulnerable to predators that eat the “natural” foods. This is when the plants are protected by fenced in areas so animals such as deer, rodents, or anything else that is harmful to the plans. Growers that are not growing organic foods use pesticides and are the only toxic substances released intentionally into our environment to kill living things.
Nowadays, agriculture is an occupation that many people in the world earn it for living. For the increase in amount of agriculture areas, it makes the agriculturists compete with another for the best crop for sale in the market. The technology becomes a main function for improve the better products. Fertilizer is one of technology which is important for agriculturist; fertilizers are added to soil to supply essential elements to the growth of plants. The most common fertilizers are organic fertilizer and chemical fertilizer.
