I doubt the problem is in detecting illegal activities harming the environment.
And deploying iot devices across million km, I highly doubt this is economically viable, even if the devices cost nothing, deploying them would be a huge investment.
Surely satellites can already do a decent job of detecting illegal activities, at scale. Research funding continues going downhill with non sensical investments.
