Detailed explanation-1: -Soil degradation, water pollution, and greenhouse gases are the main bad effects of modern agriculture on the environment.
Detailed explanation-2: -Detailed Solution. Ozone depletion is not the effect of modern agriculture instead it is the result of CFCs, and HCFCs.
Detailed explanation-3: -The modern farming methods use excessive water, which may ultimately lead to water shortages. The application of modern techniques results in the eradication of essential microbes from the soil, which may eventually result in infertility of the soil and unhealthy crops in the long run.
Detailed explanation-4: -Under water-logged conditions, pore-spaces in the soil get fully drenched with water and the soil-air gets depleted. The water table rises while the roots of plants do not get adequate air for respiration. The mechanical strength of the soil declines, the crop plants get lodged and crop yield falls.
Detailed explanation-5: -Hence, the correct answer is (b) Deforestation.
