We do not know the consequences yet. But that is partially what makes it scary. Having no idea what consuming all this plastic (animals in general, not just us) will do mixed with it being extremely widespread makes it a very scary situation. These are clearly foreign objects being forced into our environment in ways that haven't been seen before. Cleaning up the issue, and working out the side-effects should go hand in hand. We could possibly be having an effect on our environment directly with our actions and we are trying to figure out how to stop it. Solar roads is more of a fad "solution" to the issue. Microplastic is the problem.
