The problem with banning the sale of New IC engines by 2040, is the electric cars are run off the electric grid. They are changing one fuel source for another, and while more efficient, if you live on a coal powered grid you haven't lowered your carbon footprint all that much. Now when I say problem, I'm not saying we shouldn't do it. I'm saying we need to do another thing at the same time to maximize it's effectiveness. And that is reduce our dependency on fossil fuels for power production. And we have several options, like nuclear energy. We've come along long way since most of our nuclear power plants were built. We can upgrade em, and plop down more, they take so long to build we would have plenty of time to phase out coal and gas power plants without sending the economy into a tailspin.
Because we are halfway to the point of no return concerning the 2 degree cap we've set ourselves. And their is still enough oil in reserve at the moment to hit that mark five times over. Which if we're smart we will stop burning it, and keep it for the other things we create from it.
There is literally nothing we can do atm concerning mining, it sucks how bad that is for the environment but we need the materials to make the new things we have to build to replace the old things. We can offset the damage by cleaning up our trash act. For instance, why do we let companies sell everything in disposable packaging? Take Coca Cola for instance, I'm told that back in the day they used glass bottles you could return. They would then wash and reuse the glass bottles. Why does everything have to be individually wrapped? Why is it the consumers fault the company is creating this trash for us to throw away? Because I'm fairly certain I like Coke enough to buy it in a glass bottle. Heck, I prefer it actually, makes the flavors more crisp. So why is it my fault it's being sold to me in a one use plastic bottle that will likely end up in a landfill. Our local Boston Pizza delivers their food in reusable Tupperware, why is that not more of a thing? There is a great deal we can do to clean up our trash, if we look towards who is actually producing the things we throw away and why. Instead of blaming the consumer for their choice in disposing of the trash that wasn't necessary in the first place.
