The clickbait headline might more accurately read “Toxic pesticides and chemicals are poisoning wildlife and water in America’s public forests.”
The “non clickbait” headline obscures the truth: illegal drug producers have no qualms about illegally using land and illegally using pesticides. The key part of the story is that these are illegal pot growers — this is key to the story because if pot were less regulated, like sorghum for instance, costs would drop to commodity levels and take the profitability out of illegal operations.
