the link does not work anymore Startup. i know, that at the beginning of this month the treaty to ban persistant organic pollutants (pops) has gone into effect, which among others bans DDT.
the DDT scare begann in 1962 with the book "Silent Spring" by Rachel Carsons and it is true, that DDT accumulates in fatty tissues over time, so it should not be used in agriculture, however the first world has been pressuring the countries dependant on economic aid to completely back away from using DDT, even when it is only used to fight the malaria mosquito (at least Germany did).
so after malaria had almost been eradicated thanks to DDT the mosquito has made a comeback with 500000000 people worldwide carrying the desease and one death to it every 30s, which makes the environmental whackos and their ideas more dangerous than some warmonger.
i dont think it is the intention of the first world to keep the world suffering from malaria, it is just that they are caught in their ideologie of everything "unnatural" being bad, leading to chemophobia and aversion against things like genetic modification.
people like Lorraine Mooney from "save children from malaria", a southafrican organisation and even Nader have spoken against outlawing DDT.
