What huge envrironmental cost of batteries?

Australia mines >50% of the world's lithium and 1% of worlds oil, and for them oil pollutes more

And lithium is recycled, oil is not.

Oil is a biohazard, we had massive oil spills wich posioned areas as large as fukushima exclusion zone. Pour barrel of oil in a forest, and everything dies

How many lithium spills were there? Zero. If you sprincle lithium in a forest, nothing happens.

I don’t know enough about the battery supply chain: but, generally speaking, centralizing problems often makes it easier to fix them by giving maximizing the leverage of improvements.

Gasoline doesn't just magically appear at the pump. Oil extraction has huge environmental costs too.
