Many foreign countries began to discover environmental problems. Russia, Sweden and New Zealand banned DDT. The Japanese in particular were enraged by the effects of forced-draft industrialization on their lovely country. After 48 schoolchildren were felled by photochemical smog in Tokyo last summer, kogai (environmental disruption) became the nation's top issue. Last week Japan's Diet responded by enacting 14 tough new laws aimed at sending big polluters to prison...

Legal actions prodded the Departments of Agriculture and HEW to expand ?and start enforcing?an existing ban on DDT. In Alaska, the controversial pipeline was delayed in part by a private suit citing the Environmental Quality Act of 1969, which requires federal agencies to study the environmental impact of any new project?and make the studies public...
Metcalf estimates that Lake Michigan contains 10,000 Ibs. of dissolved DDT. About 50 trillion insects leave the lake annually, each one containing .0000001 gram of the pesticide. If 10% of the bugs were trapped and burned every year−and no more DDT was sprayed around the watershed−the lake could be free of the pesticide in a decade...
...secret that U.S. waters contain noxious substances like DDT, lead and mercury. The mystery is how to remove them. The pollutants are dissolved in such microscopic particles that they cannot be sifted or scooped out by chemical or mechanical means...
...great part of their lives as larvae in the water before metamorphosing into their more familiar buzzing selves. In a controlled experiment, Metcalf built a small tank to duplicate the ecosystem of a lake and its shore. He discovered that adult mosquitoes leaving the tank contained concentrations of DDT 100,000 times as strong as could be found in the water itself...
