Hello everybody, I think that we have to be honest with ourselves, everybody wants to save the planet and be a good ecologist in this world. But I think that if we wanted to be a real ecologist we  would have to be an extreme ecologist because to defend a cause we have to be an exemple. I mean that our foot print has to be approximately equal to zero. But be this type of hero doesn’t exist because it has a price and no one wanted to take this responsibility. I think that nobody want ’s to renounce to our privilege so we do some little things to say that we are ecologist and be accepted in this society. But that will not change anything, one man’s action can’t change anything. You will certainly say me : « if everybody do this little action it will make a great thing », but just for exemple turn of the light when we go out of our room is really really insignifiant when we are wearing clothes which have travel the whole world in a plane. You can do what you want but for me a decided to be honest with myself and be happy to be in this beautiful capitalist world.

The reason the things we do to reduce carbon footprint can seem insignificant sometime is because most pollution and carbon emissions come from major companies around the world.

This doesn't mean it's not good to make an effort to reduce your carbon footprint when you can, though. And this world being capitalist is not really the best option for earth's future at the moment.

While it’s true that small actions like turning off lights make very little difference, this doesn’t mean we should accept our fate. Ignoring the problem is exactly what previous generations did that led to the current situation. It’s our responsibility to give future generations a chance to live. Instead, this just means that we need to make a radical change to the very way we think. For example, using your analogy, we would need to start manufacturing clothes locally and reduce the carbon emitted from shipping products around the world. (This also means we should dismantle capitalism, which is responsible for the current consumerist mindset that is leading to rising carbon emissions.)

It's true that our efforts might be insignificant, but that doesn't mean you just stop. You have to push for larger efforts to be made. I noticed you mentioned capitalism - in my opinion, capitalism is actually one of the main reasons why our climate is as bad as it is. @girlboss already made a great example of why capitalism makes things worse, you should read their comment thoroughly.
