Very often these personal efforts are simply virtue signalling or a way for people to feel better about themselves. Doesn't mean that you should be wasteful with your resources or actively damage your environment but please, don't pretend to be saving the earth by drinking less milk.

Where a difference can be made:

- politics - if you are in politics yourself, or you can lobby and exercise some pressure to dictate policy, that can go a long way

- industry leaders can actually make a difference but don't have the incentives for it

- research and innovation - if you're an engineer this is probably where you can make the biggest difference even if you're unlikely to be one of the few people who have a breakthrough - renewable energy, alternative materials, new ways of food production and so on - you can put in work to improve the technology behind any of these to the point where they make more economic sense
