> Whether your choice as an individual has a significant effect is another question. But it’s undeniable that one choice is better for the environment than another. As people we can make the better choice or the worse choice. It’s up to us as individuals.
Sure, but such an impoverished "choice" is essentially "do nothing" or "do nothing, with the option of eating tuna". It's basically table-stakes: once you've made the easy choices you have control over, it's time to make difficult choices which involve many people. (I see voting the same way: the first step of political engagement)

That's a straw man; nobody is saying that's a solution. If you insist on viewing everything through the lens of individual choice, then we can just apply your own reasoning to more impactful choices, e.g. as an individual I can:
- "petition legislatures for stronger fishing regulations" or "don't petition legislatures for stronger fishing regulations"
- "file lawsuits against organisations/individuals breaking regulations" or "don't file lawsuits against organisations/individuals breaking regulations"
- "campaign for representatives with good environmentalism credentials for key posts" or "don't campaign for representatives with good environmentalism credentials for key posts"
- "infiltrate and disrupt environmentally-damaging organisations" or "don't infiltrate and disrupt environmentally-damaging organisations"
- "help organise and spread awareness of collective efforts at systemic change" or "don't help organise and spread awareness of collective efforts at systemic change"
- etc.
These are all individual, personal choices; and are likely more impactful than choosing whether or not to eat fish. Since it's pretty cumbersome to talk about "individually choosing to work alongside other individuals in an effort to support each others' efforts to implement changes that adjust the cost/benefit ratio of the choices of other individuals who may have large impacts on the environment", it's common to abbreviate this using phrases like "collective action" and "systemic change".
