You don't need 'more' regulation, but probably different regulation.

So eg instead of having lots of piecemeal regulation that bans straws and plastic bags and Kinder Surprise eggs etc, you can have a single relatively simple tax on plastic garbage. The total amount of regulation would go down, but effectiveness would go up.

(You can give companies who collect and deal with their plastic trash a discount on the tax, if you want to.)

Similar for carbon dioxide emissions tax, instead of silly gameable things like CAFE car standards.
