The increase of food production owns much to fertilizers and better machinery, but some people say it has a negative impact on human health and community.To what extent do you agree or disagree?

Write at least 250 words.It it evidentially true that advanced machinery and fertilizers, to a large degree, optimize food production.However, by giving it all negative comments, I believe it unreasonable and irrational since it merely represents only one single step rather than the entire proceing procedure.It cannot be repudiated that side-effects fertilizers and machinerybring about are somehow obvious.For instance, the chemical substances detrimental to health seep into crops and vegetables along withfertilizers.Sometimes, overdose of any chemical may directly result in certain degrading of body organs.More seriously, the universal application of machinery may replace human labor force as a more efficient substitute, which may lead to the rise of unemployment.Besides, the waste gas generated by all those units will definitely contribute to local air quality or perhaps global warming.Neverthele, is it true that we, as human beings, should leave all these inventions behind and pretend they have never made a great difference?

On the other side, it is a logical error to take one certain step as the whole proce.Currently, along with scientific advancement, people rarely take raw food as in the past.Thanks to the perfection of food proceing industry, there are more procedures, such as filtering, degerming, or low-temperature evaporating, to guarantee food quality harmle to human bodies.In addition, many trace elements and other nutrient vitamins are, through advanced operation, compoundedin the food in order to improve the nutrient composition of the food itself.Therefore, it is fairly aertive and parochial to claim fertilizers and machinery have a negative impact.And more ironically, if human beings did not apply them in food production today,there would be no way to feed growing world population.As was previously stated and well discued, the role and function of fertilizers and machinery in food production is overgeneralized and misinterpreted.Personally, they both serve well in food production, and their flaws are avoidable most of time.
