That's the point: understanding that individual virtue does absolutely, totally, precisely nothing. Only collective actions count. At all.
Understanding orders of magnitude is not something that comes easily to humans but it must be understood to work on large problems.
Collective actions start out as individual actions and like that they set the stage for change that is real and measurable.
By your reading Rosa Parks should have just shut up and sat in the back of the bus because 'individual virtue does absolutely, totally, precisely nothing'.
Understanding orders of magnitude is indeed not something that comes easily to humans but it must be understood to work on large problems, right alongside understanding how social change is engendered.
If you take one less flight this year, you've considerably lowered your carbon footprint. Congrats. If every single person that flies reduced their carbon footprint by one flight this year like you did... it would make absolutely no meaningful difference with respect to climate change. You might as well whistle in the wind. On the other hand, if all of those people had actually taken political action, meaningful change would be practically inevitable.
The narrative that encourages recycling, buying green brands, and generally expressing how much you care about the earth by how you choose to shop (making your environmentalism part of your identity as a consumer rather than as a citizen) serves only the status quo, and dissipates energy that might otherwise be channelled into making an actual difference.
One is forced to wonder why people who think this way bother to get out of bed in the morning. On a global scale you are insignificant approaching nonexistent, so by your own reasoning nothing you do matters and therefor you shouldn't bother doing anything.
Because they get hungry. You are animal, you don't need a noble cause to do things.

As I said: Not for very long. Besides, I wouldn't call that reason (except for people who do that to die, it's pretty efficient for that purpose).
In fact, even literally throwing up your hands is a waste of energy.
Quite a few philosophers of politics and radicals would agree with that statement; from SEP[0]:
>There is some debate among economists and political scientists over the precise way to calculate the probability that a vote will be decisive. Nevertheless, they generally agree that the probability that the modal individual voter in a typical election will break a tie is small, so small that the expected benefit (i.e., p[V(D)−V(R)]) of the modal vote for a good candidate is worth far less than a millionth of a penny (G. Brennan and Lomasky 1993: 56–7, 119). The most optimistic estimate in the literature claims that in a presidential election, an American voter could have as high as a 1 in 10 million chance of breaking a tie, but only if that voter lives in one of three or four “swing states,” and only if she votes for a major-party candidate (Edlin, Gelman, and Kaplan 2007).
Chances are, you can use the time to do other things, things that gain you more benefit than "a millionth of a penny" (if we must use the economism of time = money).
It's important to do both, but saving the planet will only be accomplished through collective action.
I'd agree if you said enforced collective action. We cannot rely on companies to self-regulate. There needs to be severe consequences for companies that damage the environment like this. As long as profits far exceed penalties, companies will continue to take the easy path.
Any collective, corrective action must include corporate action, or it is futile.
