is mainly because of the corruption at a local level.

I worded myself badly at the end, I meant any drinking water. I agree regarding clean water, however fresh-water is going away and without desalination plants being built, which they aren't, we're going to be fucked as we're running out of non-salted water.

The others (sun, wind, water) are not beneficial yet

They are, wind is pretty shit, but solar can be good, but the better ones are water as they can provide protection as well from hurricanes and tsunamis.
Tesla cars and their battery are not ideal, but they're still way better than gas-powered vehicles, especially if you don't make them so luxury and reduce the weight.

As to how to reduce it otherwise, consumption in general, ban, outright, or downright hang the dirty capitalists that produce garbage products with the purpose of them breaking down in a short period of time so you have to buy another.
Headsets shouldn't break in months or even a year, they can easily last for 10+ if desired, but instead we use small thin wires and poorly made protectors so that they break earlier, and then they throw all that in the bin and buy a new one.

It's really a simple problem to solve, it's just everybody with the power to solve it benefits from the problem.
They'll reap what they sowed and probably be brutally murdered in a couple decades if they don't go hide out in bunkers though.
