Or even a decade earlier: > Opposition to DDT was focused by the 1962 publication of Rachel Carson's book Silent Spring. It talked about environmental impacts that correlated with the widespread use of DDT in agriculture in the United States, and it questioned the logic of broadcasting potentially dangerous chemicals into the environment with little prior investigation of their environmental and health effects. The book cited claims that DDT and other pesticides caused cancer and that their agricultural use was a threat to wildlife, particularly birds. Although Carson never directly called for an outright ban on the use of DDT, its publication was a seminal event for the environmental movement and resulted in a large public outcry that eventually led, in 1972, to a ban on DDT's agricultural use in the United States. https://en.wikipedia.org/wiki/DDT#History https://en.wikipedia.org/wiki/DDT#History By the way, you can get Silent Spring for free on https://www.fadedpage.com/showbook.php?pid=20151002 https://www.fadedpage.com/showbook.php?pid=20151002 – and it is still very much worth reading; eloquent and poetic while still being factual, informative and balanced. The producers of DDT and other poisons started a smear-campaign after the publication, but it only lead to a Streisand-effect.
