Pesticides

This article explains that additives in pesticides make their active ingredient more effective, up to one thousand times more effective in some cases. It explains that safety tests on pesticides typically only target the active ingredient, so this news means that pesticides are much more dangerous than previous testing revealed. A product called Roundup, sold by Monsanto, proved to be the most toxic of the herbicides and insecticides tested.

The article does not really explain what this means for the environment, so I think that communicating the effects of this is important so that people can understand the sustainability problems it causes. While the pesticides itself have not changed, we are just understanding how toxic they actually are, it is still important to note they have an adverse effect on the environment. Monsanto is a company subject to a lot of scrutiny, putting profit over health. I think it is necessary to do some more research to understand what this means and what the alternatives are.
