Nowadays consumers demand cheap food so more of corn and soy are in demand. Farmers grow these crops consistently which is known as monoculture; because of this the soil depletes and forces farmers to use greater amounts of pesticides and fertilizers. Even the animals are fed corn, which again motivates farmers to cultivate the same crop. The effect of food on climate is scary. Because of monoculture lot of pesticides and fertilizers are used.
They always notice that corn is a cheaper product, but they do not even appreciate the sacrifice of most of the corn farmers throughout their life. The researchers want to find out the problems that faced by the corn farmers not only in financial aspects but also in their social, economic and physical aspects. Most neglect the importance of corn. They see it as low source of income. Many corn farmers also encounter problems that can contribute to poor harvest.
However, the question as to how beneficial the Agricultural Revolution was to humanity remains. Some people argue that the Agricultural Revolution offered and illusion of lavish life, but at more cost than benefit. For example, Friedrich Engels, co founder of Marxism, believed agriculture the direct cause for a loss of political innocence (Noble or Savage 2). Others argue that agricultural came as a great success for the survival of the human race, and believe it to be crucially beneficial to the development of humanity. Both arguments have their flaws and strengths, however, evidence suggests that the Agricultural Revolution benefited humanity from the perspective of a larger group, but came as a deficit to humanity from the perspective of the individual human.
It means if there is a biodiversity crisis, our health and livelihoods are at risk too. For instance, wild fish make a critical contribution to food sources in many countries, especially those with high levels of poverty and food insecurity. The aquaculture industry leads to the pressures on global wild fish stocks that restrain the food supply for people in developing countries and removes large quantities of small fish from the ocean food chain. Farming carnivorous species, like salmon, require large inputs of wild fish for feed. Some aquaculture systems totally depend on wild fish supplies.
In order to survive or in for survival the process of conservation is needed for every living organism. Even an ant conserves food to so that in winter season there should not be any difficulty in searching for food. Our planet Earth is the home to many diverse lives which vary from each other. We popularly call this as biodiversity as biological diversity used for describing the variety of lives present on earth. Habitat destruction or excessive harvesting of particular specie may prove to be a threat to biodiversity conservation.
There is an increasing effect of climate change which has led to drought which has led to the withering of the crops and reduction in crop and animal yield. It’s therefore important to scrutinize agricultural production system for their sustainability because through scrutinizing, it will ensure that proper methods and processes that improve soil productivity are adhered to while minimizing harmful effects on climate, soil and human health. Scrutanization also ensures that famers use inputs which are from renewable sources and avoid those which are non-renewable and the petroleum based products which enhances a clean
Contribution of chemical fertilizer and pesticide industries to climate change is well known (Leis, 2008). Food is and will remain at the centre of this unfolding climate crisis. Everyone agrees that agricultural production has to continue to rise significantly over coming decades to feed the growing population. Climate change however is likely to put agricultural production into reverse. Impact of global warming on agriculture is estimated that in future climate change will reduce the potential output of global agriculture by more than 3.2 percent as compared to today (William R. Cline,
Initially, soil fertility can increase following deforestation, especially when the forest is burned rather than logged reported by Uhl (1987).Conversion from forest to new forest has smaller long term dramatic effects on soil organic Carbon and bulk density compared to conversion from forest to cropland. It matters whether forest is converted to cropland with annual crops (e.g. maize, cassava, or soy beans), perennial crops (e.g. oil palm, cocoa, or rubber), or forest plantations. The conversion of forest to perennial crops usually results in lower levels in the rates soil fertility decline because – to some extent - these systems mimic the forest cover (Hartemink, 2005b).
Another way in which agriculture increases the rate of global warming is through deforestation with the aim of clearing lands for agricultural purposes. Many of today’s lands under agricultural activities were previous forests that covered massive tracts. The cutting of trees reduces the rate of removal of carbon dioxide from the atmosphere, which directly leads to its accumulation within the atmosphere. The result is the rise in global temperatures. Deforestation continues to be rampant while reforestation efforts are capped by selfish capitalist gains by individual large-scale farmers whose aim is to rake in more profits annually (Haldar, 2010).
