Re “California’s timber industry was sacrificed for the spotted owl. Now pot farms pose a new threat” (sacbee.com, Jan. 11): We’ve always known rat poisons have killed a lot more than rats. The highly toxic poisons have not only wreaked havoc on California wildlife but posed an invisible threat to our pets and children. The new UC Davis and California Academy of Sciences study makes clear how use of the poisons on California’s pot farms is sentencing some of our most imperiled wildlife – including northern spotted owls – to painful death. When Californians voted last year to legalize recreational marijuana, that approval required the state to established measures regulating growers’ use of pesticides, energy and water. But the state’s current plan not only fails to adequately prohibit growers from using wildlife-killing rat poisons but also fails to adequately assess harms from projected increases in use of pesticides, water and energy.
