30 years is not a good enough sample. In fact it's pretty bad.
We do have more data available than just what one farmer experiences.
Nonetheless, what is a good response to it?
I don't have the feeling that just ignoring it or not doing anything is a good approach.
What's the point of "the issue is more nuanced!!1!" all the time? We collectively need to act now. Everyone of us. You are draining momentum to what end?
