Explain why it's heavier? Because electric vehicles carry all the chemistry, while gasoline powered vehicles only carry carbon and hydrogen and take oxygen from the air.
Or explain why the difference in weight is negligible? But it's not, electric vehicles are noticeably heavier, and vehicle weight is the primary driver of tire wear and road wear.
The bigger problem with EV revolution is carbon footprint of its side effects, e.g., extra emissions from producing and utilizing batteries, or extra particulates from tire wear due to weight of electric vehicles.
It's not enough to plant trees. Fallen trees rot and release CO2 back in the atmosphere. You need to cut the trees down, then use lumber for building something, and bury the rest so that it does not decompose.
Regular forests work just fine, and we have been doing logging for a while so sequestration is not a problem. We just need to do it more, and selectively, not cutting down everything at once.
