As an ecologist, I often get questions about how to be more "environmentally concious", and one thing that I noticed is that a lot of people have a kind of "all or nothing" mentality to it.
A lot of people feel as though if they can't do something 100%, than it's not worth trying. I feel that type of logic is also perpetuated by many of the public figures/influencers that talk about this. But the fact is, there is no all or nothing here. You don't want to or can't be a vegetarian? That's fine! Even reducing your meat consupmtion by 10%, or even 1%, is already useful. You sometimes forget your reusable bag? No worries! Use the plastic ones, you're not going to ruin the earth by doing it. You can't bike to work? So what! Drive if you need to, if you can cut just one trip short and go to two places at the same time, you will already be doing good. You can't afford to or don't want to stop buying fast fashion? That's ok! Did you donate some of your clothing? Did you mend a little hole on your shirt instead of buying a new one? Did you wear something for multiple seasons? No matter how small, what you are doing matters!
Until we talk about these things as being a gradient, we will never see real change. Instead of shaming people who you think aren't doing enough, praise every small bit of progress.
But most importantly, remember that the biggest and most valuable thing you can do for the environment is not to use reusable straws, it's to VOTE for politicians who implement policies protecting the environment. We can all do all the things that are reccommended to consumers, but that's not enough. The problem isn't individual people, it's corporations and governments. So you can be the worlds biggest meat eater, drive a giant SUV, buy a new shirt for every day and never recycle, but if you VOTE for green policy changes you will still be doing more use than someone who doesn't.
