I have no time to virtue signal by participating in meaningless social activism. I will help individuals where I can because that is somewhere where I can meaningfully affect change with my actions.
Maybe it's my age. Maybe I'm cynical, I don't know. I used to care about these things. I bought a crappy house in a crappy neighborhood to save gas. I wasted money on a solar panel system. I planted native plants, composted and grew my own fruits and vegetables. I was worse off for it, and no change came from it. If I managed to save any resources, they were quickly consumed by some other wasteful excess of society.
Unless your activism is effective, it is useless. It is basically religion at that point.
You are also constantly bombarded by messaging telling you not to and to focus narrowly on short-term self-interest, from the opposite side of the political spectrum.
The one you view as “pestering” is just the one you haven’t internalized.
Any of these problems, can directly affect your children.
Let me tell you one example, my parents generation suffered much higher cancer rate than normal. That's caused by 40 years of rapid industrialization in China.
Think about it, these issues let limbo, will very likely make your retirement miserable in 20-30 years...
