The Controversial Use of DDT in South Africa

It is shows that using DDT can have bad effects on the environment and human health, but the fact that DDT is remains the best known pesticide to eradicate malaria should not be ignored (Roberts et al,2000). I personally believe that human health is of the out-most importance and should be treated as such. It should be protected in all ways possible. With that being said, I believe that countries should continue using DDT as a malaria control and save lives of people that are exposed to the disease, but should discontinue its use in agriculture.
