> reduce the impact on nature

Less bad is not the same as good. For example, electricity from solar panels is less bad than electricity from fossil fuels but there's considerable disruption to the natural world to produce them, not least of which involves mining for raw materials. In the same vein, we're nowhere near reducing pollution to safe levels or even reducing our overall pollution, all we've managed so far is a reduction in the rate of growth of fossil fuel use, it's still going up YoY.
