Well 1) living has a massive impact on the planet because everything we do leaves a mark and everything we eat redirects energy into our bodies so that ship has sailed and 2) a 10% reduction in currents and wind specifically would have massive impacts on the planet’s currents and wind if we built enough power plants that used those sources of energy specifically to power the entirety of human civilization. We have other options, and the way we source power (as a planet, never mind individual jurisdictions) is basically an “all of the above” energy strategy in practice. However we can source energy, we do it.
