Pesticides are important. They help farmers grow more food on less land by protecting crops from pests, diseases and weeds as well as raising productivity per hectare. Production of major crops has more than tripled since 1960, thanks in large part to pesticides.
Why do farmers use pesticides and fertilizers?
Fertilizers are used to supply crops with essential nutrients for growth and to help replenish the soil of key elements once a crop has extracted them during the growth process. Pesticides are chemicals which are used to control weeds and insects which pose a threat to crop production.
Why we should not use pesticides and fertilizers?
Excessive use of fertilizers and pesticides by farmers in agriculture to enhance crop yield is detrimental to environment and human health. Fertilizers and pesticides use has led to the problem of air, water and soil pollution.
What are the pros and cons to using pesticides and fertilizers?
The pros of pesticide and fertilizer use are offset by the problems related to their toxicity. For example, one of the many negative effects of pesticides has to do with the depletion of beneficial organisms. Many pesticides used to protect crops from harmful pests often kill beneficial insects.
