...Fathers to double the figure. When he was writing Brave New World, in 1931, world population stood at just under 2 billion. Today, "only 27 years later, there are 2,800,000,000 of us." People keep breeding, as it were, behind Huxley's back. Clean water, penicillin, DDT are also to blame, he says. Soon there will not be enough to eat, Huxley warns, and suggests that occupancy of this planet by more than 3 billion persons is dangerous and should be unlawful...
...into a hut, rests a while on a wall, buzzes down to gorge herself on a drop of blood (often, in the process, infecting her victim with the parasites in her saliva), then rests on a wall before heading out. In a dwelling whose walls have been sprayed with DDT, these pauses are her undoing. As long as six months after a spraying, there is enough DDT left to kill her soon after contact...
From House to House. The shift in goals-from mere "malaria control" to complete and quick eradication-was dictated partly by the success of early campaigns in Sardinia, Italy, Greece and Chile, partly by the danger that unless the attack is promptly pushed, the DDT-resistant strains of Anopheles may get out of hand. Abandoning area spraying, the malaria fighters are tackling the huge job of spraying every dwelling in malarial regions. Walls are saturated with DDT as fast as possible; scheduled are at least three more annual sprayings. This way, doctors believe, the cycle of mosquito-man-mosquito renewal...
...Anopheles should be prevented from starting any new infections, and old ones will eventually burn out because the parasites lose their reproductive powers after two or three years. In areas where the mosquitoes are resistant to DDT, another insecticide, dieldrin, will be used. Where the mosquitoes bite in the open, preventive drugs will be used in addition to spraying. Example: the entire table-salt supply for the Amazon Valley is now being laced with chloroquine to build up the inhabitants' resistance...
...large fire extinguisher. In Mexico, 3,500,000 houses have been sprayed. The program is well along in Central America, coastal Ecuador and Peru, Formosa, Swaziland and Ceylon. It is finished in northern Venezuela, several Caribbean islands and parts of Argentina. Soon to feel the fine spray of DDT are Turkey, Iraq, Iran, Afghanistan, Burma, the Philippines...
