What’s wrong with pesticides?

<Pesticides are designed to be toxic. Many pesticides are severely harmful to human health and the environment, and responsible for the poisoning of numerous people, livestock and wildlife.Some have been linked to cancer. Some are based on WW2 nerve gases and damage the nervous system, whether insect or human. Many also disrupt the hormonal balance in our body: they threaten our potential to reproduce, and to have healthy offspring. Finally, some pesticides remain in the environment for decades: they accumulate in the fatty tissues of animals and contaminate the environment far from where they were used.

sorry. Thanks, but this is a charity site and upgrading from 1.5 is not going to be straightforward when they have no web dev budget, have a heart!
