Pesticides

The Guardian, 10 Feb 2019

The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review. More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. The total mass of insects is falling by a precipitous 2.5% a year, according to the best data available, suggesting they could vanish within a century.

The European Parliament has voted to adopt the final report of the Special Committee on Pesticide Authorisation (PEST), which calls on EU governments and the European Commission to make the authorisation procedure for pesticides more transparent, to take decisions based on independent scientific evidence, to test pesticides and pesticide active substances more rigorously for health and environmental risks, and to re-assess the product glyphosate for its cancer risks.

The US EPA considers glyphosate as “not likely to be carcinogenic to humans.” The International Agency for Research on Cancer (IARC) has classified glyphosate as “probably carcinogenic to humans (Group 2A).” EPA asserts that there is no convincing evidence that “glyphosate induces mutations in vivo via the oral route.” IARC concludes there is “strong evidence” that exposure to glyphosate is genotoxic through at least two mechanisms known to be associated with human carcinogens (DNA damage, oxidative stress). Why and how did EPA and IARC reach such different conclusions?
