Is it such a shock that chemicals that kill one class of living thing (plants) may have some biological impacts in another class (mammals)? We have a long history now of inventing wonder weed killers and pesticides that later turn out to be unsafe. #Glyphosate https://twitter.com/Andreleu1/status/1282859258015387648

2/ In the end, the safest way to grow food is via intelligent intervention and subtlety. This goes for conventional farming as well - if you're going to spray, be targeted and do it to the minimum extent possible. But our entire system is designed to minimise human labour....

3/ And to keep farmers close to the financial edge so they'll always choose to play it safe even if the end result is people eating more poisons, because there's no financial buffers in the system.

4/ So instead we get overkill dumb spraying because it's cheaper and looks less risky than having enough eyeballs on things to decide when to intervene.
