there are a million answers to this, but what comes to mind as some of the biggest ones?
I have to research a few of these, preferably something has has improved existing products to make them better for our health/the environment.
One big one is unleaded instead of leaded gasoline.
Any other major ones come to mind?
thanks for any input
