Tire wear right now is worse, because tires contain an anti-oxidant that gets oxidized into a compound that is highly toxic to aquatic life.

The work is underway to standardize on a replacement. This time with even more tests.

Not really. There are plenty of possible replacements, the industry wants to make sure that _this_ time it won't hurt some Australian finches if tires are exposed to moonlight or something.
