This is not only in the US. We don't know what is being sprayed or for what purpose, but anyone with eyes and who has been alive for 20 years or more should know the trails are now different. Has airplane tech changed in the last 20 years? Yes, of course. But I have not been able to find someone to explain to me how those trails stay up there for so long like they do. On top of that, we have farmers telling us the land changed when the planes started spraying. These farmers have worked the land for generations and generations, they can tell you when something has changed in the enviroment. If they say we should be looking at the planes, we should be looking at the planes.
