Yes, microplastics are bad, but the comparison between electric and ICE cars is just not true at all. Mineral mining can be bad, but it's mostly bad because bad is cheap, and they can get away with it in third-world countries with lax environmental protections; however, even given this, when a battery wears out, all it is is a change of configuration of the materials that make it up, which you can reclaim, and we're getting better at reclaiming those disordered elements in used batteries. So the percentage of reused minerals in batteries will continue to climb. ICE cars combust fuels which are used up and turned into water and CO2, which is bad and requires more fuel. Also, yes, e-bikes are good.
