I'm all for healthcare, but, on topic, it'd make even more sense to find replacements one-at-a-time for all of the products we use daily that are made up in part by crude oil.

Most plastics, many foods, many skin products, etc. all come from some by-product of oil. Because of that dependence, big oil is not only a huge industry, it's most industries, most company, most products, and touches most consumers.

Also:

"There are 1.65 trillion barrels of proven oil reserves in the world as of 2016. The world has proven reserves equivalent to 46.6 times its annual consumption levels. This means it has about 47 years of oil left."[1]

Wars have been fought over it when we still had a lot left, and we've got until maybe 2068.
