Topic statementIn recent decades, there has been a number of high profile innovationsđổi mới in farming based on scientific research, most notablyđáng chú ý the use of chemical insecticidesthuốc diệt côn trùng and the genetic modificationsự biển đổi gen of crops.
Topic statementWithout doubt these have led to some very positive outcomeskết quả. ExampleFor example, researchers have been able to identify which pests cause problems for a particular plant and to create a means of destroying them. Supporting statementIn some areas of the world, this has transformedchuyển đổi farmers’ ability to grow food for their own consumptionsự tiêu dùng as well as to sell it to generatetạo ra incomethu nhập. Supporting statementEqually, in recent years, the ability to manipulateđiều khiển, thao tác the genetic make-upcấu tạo di truyền of plants has made it possible to create strainschủng, giống of crops naturally resistantcó sức kháng cự to pests and diseases. Supporting statementIn fact, some of these new scientific developments are reducing the need for the innovations of the previous generation.
Topic statementHowever, there can be serious drawbacks to these scientific developments in agriculture. ExampleFor instance, it is now becoming clear that pesticides may be damaging beneficial organismssinh vật as well as pests. ExampleFor example, it is widely agreed that the world’s bee population is being affected by chemicals; this means fewer plants are being pollinatedthụ phấn, which affects food supplies. Supporting statementIt is possible, also, that a range of human diseases which are becoming increasingly common, for example asthmahen suyễn, may be exacerbatedlàm trầm trọng hơn by these chemicals.
OpinionMy own view is that it would be wrong to deny the potential of science to improve agriculture – as it has done throughoutxuyên suốt history, from the development of the ploughmáy cày to the refinementsự cải tiến of livestock breedingchăn nuôi. SummaryHowever, we must be sure we understand as much as possible about the effects of innovations before it is too late to reverseđảo ngược any negative consequences.
