The negative effects of lead and asbestos are known and abatement is ongoing. There are grants being administered today to aid in their continued abatement.

The negative known effects of microplastics are emerging. The public are not as aware of the extent to which they are exposed to microplastics daily. Also, we don't actually know the full extent of the damage being done yet, but what we do know so far is that microplastics affect neurological development, fertility, and are known endocrine-disrupters. It will take time to see the full effects of microplastics in our environment, and it's going to get worse before it gets better.
