Do I really need to point who is the biggest e-waste generator in the world? Solve that problem first.
It's also the consumers who are using the oil, not only the oil companies, who are to blame at the end. If no one buys, no one will produce.
Sure, if it's cheap and readily available, people will use it no matter how bad it is.
That's why it's so important that the governments increase the taxes on oil, petrol and diesel.
In many places in Europe you can get to work or holiday destinations by public transport.
In Switzerland (a rich and relatively densely populated country, albeit full of mountains) there are trains and cable cars to almost everywhere, and if not a train there is most likely a bus (managed by the post office). I managed to live there quite a few years without owning a car.
In Singapore they put a hard limit on the number of cars on the road (and no exception for electric cars, to Tesla disappointment), and the available slots are sold at auctions. There is a dense public transport system, supplemented by a relatively high amount of taxi.
What’s “that problem”? It’s not clear from your post.
We always seem to go in circles with whataboutism when posts like this appear: “X is a bigger problem so let’s solve that”. We can do this for every problem — look at the data through the right lens and another problem is always bigger - and never solve anything.
