So, they made a new chemical to make tyrea last a bit longer. But, whoopsie.. It kills these extremely environmentally-important fish, this is confirmed fact. Also, there's no way to avoid it getting into water streams if it remains in tyre formulations.

Solution 1: ban the fucking chemical and go back to prior situation.

World, apparently: no, that's ridiculous. Instead, we'll just do studies to see what people might pay for a tyre without this chemical, while we cross our fingers and hope someone makes a new chemical that's not toxic... But keep using the poison one in the meantime.
