I'm going to push back on this, largely because it assumes an all or nothing mentality which is discouraging at best.
If you look at the meat industry, and we all agree it's environmentally impactful to absurd degrees, one might apply that same all or nothing mentality here - which is incorrect. You don't need to become a vegan to have dramatic impact, but what if it became a norm to go a day without meat? We already have some religious expectations about that, we even have cultural norms that have altered what we eat and when (breakfast = sugary carbs in the West), why can we not do the same here? But this cannot happen magically, it involves individuals making the choice to encourage themselves and then their families. Everyone can do this.
I bring up a day without meat (per week) because it's a great example of how little change is actually required to have tremendous results. But we cannot get to those results if we expect some gigantic overnight change.
So going back to your article, you don't have to leave civilization entirely, and going plastic free overnight is silly. But, you can buy shampoo that comes in recyclable cardboard instead of those tacky bottles. You can eat delicious veggie meals for an entire day once a week. You can buy reusable utensils that you carry with you instead of demanding they be offered. You can use refillable containers to buy your groceries with and store them. List is truly endless.
You, yes you, can have a great impact. We as humans just struggle understanding long term impact. In the exact same way that we see someone like Michael Jordan and think he's naturally gifted, and ignore him spending 8+ hours a day practicing for years and how those choices have compounded for him.
