Whose environment is it?

Decades ago, most governments banned the use of DDT to kill mosquitoes. They did it because it was supposed to be bad for the environment. Millions of people in Africa and Asia died of malaria as a result of the ban. Now, some of those countries are allowing DDT again - because it is the safest and most effective way to eliminate malaria from the human environment. Whose environment are the environmentalists trying to protect? Not ours - not one fit for human beings to inhabit.
