Question:
Food can be produced cheaper if we use improved fertilizers and better machinery.
However some methods may be dangerous for human health, and may have negative effects for local communities.
Agriculture has become one key word in the global debate of environmental issues. some hold that improved fertilisers combined with better machinery will amount to a significant reduction in costs of producing food, while others contend that negative impacts will also ensue on human health and on local communities.
the former school of thought stands on the ground that improved fertilizers and better machinery will increase productivity. fertilizers boost the capacity of each inch of ground to churn out crops, and machinery boost the capacity of man to harvest them. and according to the theories of economy of scale, overall cost for each kilogram of crops will correspondingly decrease.
the second school has its point, though. fertilizers are unnatural products made of special chemicals. while these chemicals may enhance the productivity of the soil, they may also mutate the chemical make-up of the plants, either by affecting their genetic formation, or by getting themselves absorbed into the plants. the residues will remain in the food all the way to man's stomach. this will, of course, affect our health.
also, as the second school maintains, there is the use of the machinery. tractors and harvesting machines, unlike farmers harvesting with their reaping hooks, bring exhaust fumes to the farms and local communities, which worsens air pollution.
my judgement tells me that in the long term, we should advocate the second school of thought. we may be inspired by cheaper foods, higher consumptions and thus better GDP numbers, but if all these have to be traded at the price of our people's health, they are worthless. environmental interests have always been in conflict with economic developments, and the wiser way is to choose the latter's side.
there are, of course, things we can do. first, we can issue policies through legislation to restrict the use of fertilizers . second, we can develop new forms of nature-friendly fertilizers. third, we can reduce exhaust fumes on farms by encouraging the use of vehicles feeding on clean power, such as electricity or hydrogen fuels.
