With the need for more animal pastures, and grazing land deforestation is occurring globally. To keep a factory farm running the use of fossil fuels to run machinery, and heat barns during the winter months causes even more pollution to the environment. This magazine provides an ample amount of information to prove that factory farming is damaging the environments in many ways, and regulations need to be put in place. "Pew Commission Says Industrial Scale Farm Animal Production Poses." "Unacceptable" Risks to Public Health, Environment.
Instead, forests were used for stuff such as fences and fuel. Deforesting New England ruined forest grounds, changing the way Indians live. Cronon states, “the ecological effects of this regional deforestation were profound, extending even to the climate itself” (Cronon
The portion of agriculture in China’s GDP dropped from 28.1% in 1978 to 11.8% in 2005. In China, the food producing enterprises like agriculture and its allied activities livestock farming the small and marginal farmers have dominated horticulture, floriculture; aquaculture etc. small farmers cultivating small plots of land characterize agriculture in Asia (NCESU, 2008). China has the world third largest area of 960 million square kilometers, the arable area is only 107 million hectare, only 7% of the global arable land. Therefore, agriculture is the fundamental industry not only to guarantee the supply to food and other agricultural products for the huge population
Actually, one of the results of increased CO2 levels are the development of more weeds, pests, and diseases. As mentioned in an article called, “Effects of Climate Change on Agriculture” by North Carolina State University, “Weeds have become more prolific and are expected to invade new habitats as global warming increases.” The article also mentions that pests that may carry plant diseases will become more widespread resulting in herbicides becoming less effective (North Carolina State University). With these problems arising from increased CO2 levels, agriculture will be deeply affected.
As our population grows, we need more and more land to either live on or grow food on. This means we have to start cutting down forests to make room. The plants in the forests are what make the oxygen that we breath through photosynthesis which is a part of the carbon cycle. The more we cut down, the more we interfere with that cycle and the more the rest of the forest is affected. This interfering with the carbon cycle is also a contributor to the issue of global warming.
1.3 Purpose of the Study This research is meant to assess the impact of urbanization on agricultural land. The researcher intends to establish how the loss of fertile agricultural land to commercial and residential use is affecting food production in Kiambu county. 1.3.1 Objectives of the Study The objectives of the study are: 1. To investigate if rapid urbanization has led to change in land use in Kiambu County. 2.
These explanations are persuasive in their own right, but ecologists have increased some additional to deal with, like what would be the resultant of alteration of biodiversity on ecosystem properties, such as productivity, carbon storage, hydrology, and nutrient cycling? The apparent follow-up problem is what are the resultant of resemble largely anthropogenic alteration in biodiversity on the goods and services that ecosystems give to humans? If altered biodiversity affects ecosystem lot, is there a point at which changes in the lot might have a negative influence in human welfare? That is, those problems that being answered step by step by our own biodiversity, climate change, ozone layer begins to release the air or gas, and
Modern society is developing and changing according to the rules of globalization and overwhelming innovation. Now is the stage of human existence, when industrialization is creating huge risks for the whole world. In that context, environmentalism, as a part of modern social movement incorporates individual lifestyles with governmental control within a nation. It also has a major impact on global environmental issues of different levels of operation. The concept of “risk society” that was entered by Beck is related to the behavior occurring as a response to the modernization.
Concerns include the sustainability of increasing crop yields and intensifying agriculture, competition for land and food production, and the potential for environmentally damaging land use change (Slade). "Energy from Biomass: The Size of the Global Resource," an assessment of the evidence that biomass can make a major contribution to future global energy supply, by UK Energy Research Centre reports a figure about common assumptions for high, medium and low biomass potential estimates. Global biomass potential is measured in exajoule (EJ), and moving from the lower to the middle bands implies a dominant role for energy crops and requires increasingly ambitious improvement in the agricultural system, and changes in diet. With low population under 9 billion and crop yields outpace demand more than 2.5Gha land for energy crops, the global biomass potential will possibly be within the range 700-1200EJ. The figure shows that the biomass potential from energy crops is essentialy linked to the food demand and how it will be met.
