Should we use pesticides as they prevent our crop and food from pests or should we think of alternatives? Write your view about this issue and give a sound reason for your answer. (AS1)
i. The pesticides are non-biodegradable chemicals. These chemicals cannot decompose by decomposers (bacteria and fungi).
ii. They get accumulated in the environment and cause harmful effects to the living organisms. Therefore, we should think about using alternatives to pesticides.
iii. The alternatives of pesticides which can be used in the agriculture are: crop rotation (alternate growing of two different crops in the same field), biological control of pets for example control of mice by owl, vermicomposting (use of earthworm), using bio-fertilizers and development of genetic resistant strains, for example Bt cotton.
