Compared with the first half in the twentieth century, the world’s population has almost doubled. While figuring a solution to food shortage, many countries have adopted new methods to increase food production in order to meet the demands of growth in population. However, as far as I am concerned, to some extent, rise in food production is harmful to the environment.
First, in order to plant more crops, lands whose natures are forestry or pastures have been altered into the use of cultivated lands. We learn that forest and swamps have played an important role in maintaining ecological balance. Numerous flocks of birds and a variety of animals take them as their home. What’s more, swamps and rainforests largely determine an area’s precipitation and humidity, which affects the climate most. For instance, before a part of Amazon rainforest was explored by Brazil government or individuals, there were over two thousand species of animals living, which made a prominent contrast with the poor situation after a part of rainforest was changed into farmlands.
Moreover, some artificial inputs have to be used to ensure the production. Naturally, insects, disasters even climate changes all have negative effects on arigulture, then the use of chemical inputs becomes a must. Nevertheless, during the use of chemical inputs, it may weaken fertility of lands gradually and without people’s knowledge. As we all know, fertilizers and pesticides have strong acid which probably does harm to lands. The growth of crops may boom in one season, but the acid soil is not suitable for planting in the future. Chances are that the land is abandoned and then become dried-up. In a long run, the abuse of fertilizers and pesticides can make an irrecoverable damage to the ground.
To summarize, over-planting crops can lead to an irreversible situation by expanding farmlands and abusing chemical inputs. For the sake of nature and our living environment, I think adopting high technology is a wise choice in meeting the requirement of food for population growth.
