While you're thinking about Ebola, "Over one million people die from malaria each year, mostly children under five years of age, with 90 per cent of malaria cases occurring in Sub-Saharan Africa. An estimated 300-600 million people suffer from malaria each year."
Malaria has been pretty much wiped out in North America, but each year about 2,000 come here with it--didn't take the right precautions. DDT was discovered to be effective in 1939; the U.S. virtually eliminated the disease (about 15,000 a year) by 1951.
Ask the progressives and environmentalists why DDT isn't used today in Africa. Is it any wonder they are suspicious of western values and motives?
