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...
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...

...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...
