Modern Agriculture and Environmental Conservation

Extracts from this document...

Introduction

Is modern agriculture compatible with environmental conservation? Prior to the Second World War, the agricultural systems in many places were reliant on recycling organic matter, rainfall patterns and internal resources. The yields were stable but ordinary and most labour was done by the family. They also had no specialized equipment1. At the end of this war, the modernisation of agriculture advanced with the inventions of farm machines such as the thresher and the cultivator, as well as the increase in use of fertilisers and pesticides2. Today, the modern agriculture provides the food for at least more than 6 billion people around the world and uses almost 40% of the world's land3. ...read more.

Middle

Furthermore, the cutback on land is due to irrigation. Without irrigating the land, it is said that at least 1.3 billion acres of land would be needed to make up for the lost production. Pest control systems also increased productivity. An estimated 70% of the world's produce might be lost in the lack of pesticides, whereas with pest controls only 40% is lost4. Moreover, fertilisers have boosted crop yields meetings demands of the world's population. On the other hand, some people would believe that the modern agriculture has brought various environmental problems. ...read more.

Conclusion

Consequently, the use of these technologies amplifies the society's dependence on fossil fuel, thus increasing the greenhouse gas accumulation, air pollution and acidification. In conclusion, I believe that even though the modern agriculture causes some environmental problems, it has provided food to the world's population. Without the changes in technologies and different techniques in farming, the yields produced would not be able to meet the demand of the people. However, modern agriculture has brought serious problems and I believe that these conflicts with the environmental conservation. These problems would potentially affect the environment in the long-term such as global warming.

  2. Moscow, Russian Federation Summer-time pollution and summer smog problems

    Tropospheric ozone shows a strong positive correlation with the increasing temperature and smog formation, where photochemical mechanisms of smog contribute to O3 formation and O3 trapping in the troposphere (Mosecomonitoring 2010; Stathopoulou et al 2008; Zvyagintsev 2008). Additionally, since photochemical smog represents a "blanket" of anthropogenic pollutants such as CO,

  1. Polar Bears conservation

    It's also had a huge impact on them due to their specialized diet. They are the top predator of their region, so this exposure has been more along the lines of toxins through their food sources. Polar bears are dying out mainly because their homes are melting.

  2. chemistry of renewable resources

    The developing countries present energy markets that are very small in the relation to developed countries and this is one of the reasons why they are not developed countries. This also means that a massive production and large facilities for biofuels are not feasible or needed.

  1. Industrialized agriculture.

    Energy consumption could be decreased in this process by employing more efficient irrigation systems that reduce loss of water. 3. Mechanical Tillage of the Soil Surface. Tillage and seedbed preparation consumes large amounts of energy for the operation of machinery.

  2. Feeding The Third World

    The lack of organic input reduces the amount of humus in the soil that in turn, lowers the water holding capacity, and bacterial and earthworm content of the soil, causing it to dry out and become more vulnerable to erosion.

    Using this equation in our situation the only variable we have on the right hand side is the volume. Once a hole has penetrated the oil reservoir the restricted volume is no longer comparatively small but has become an infinite space.
