I mean building out renewable energy still has a negative impact on the environment, whether it be silicon for solar panels or concrete for hydro electric dams. Not to mention all the water that gets used to cool the massive data centers or the materials needed to create the computer components used in the data center. So sure you could lessen the environmental impact by shifting to renewables but it would definitely still be there. Reducing usage will always be the best way to help the environment, there’s a reason it comes first in Reduce, Reuse, Recycle.
I mean I think a lot of it is that at least in America when it comes to Math a lot of the teaching is more about how to use specific formulas and apply them to certain kinds of problems. They don’t really teach you what it is you’re actually doing or why you’re doing it. It just turns into recognizing a type of problem and applying a certain tool to it rather than understanding what that tool is and what it does.
