Rather than take a defeatist veiw from this line if thinking, it will do well for your mental health to first spend more time, energy and thoughts on things you can control. Not just things related to environmentalism, but broadly reduce energy, engagement and focus from the things you don’t have significant control over and direct them to those things you do have control. It’s good to get a broad picture and observe the world around you outside of your control in small doses, but it’s easy to over indulge in an unfocused survey of problems in the world, especially on social media. (I include Lemmy communities in the social media category).
Furthermore, when you do engage with these problems, do so with more narrow focus and in more depth with an eye towards understanding the level of impact the problem has and what organizations or policy positions you can support to amplify your limited influence over the issues that causee the problem. In this way you can mitigate the feelings of helplessness and sense of there being many existential and imminent problems you need to contend with but cannot remedy. You can turn seemingly untouchable solutions into real possibilities without overwhelming your emotional capacity by working with others.
I want to thank you for your reply. Hearing about someone like you and your attempt to improve your community and the world I the ways you can is so uplifting!
People are social (even the introverts) and the return on in person, deep social interaction is another reason it’s important to fight the allure of convenience of online media being ones primary and most influencial social interaction. I love that you’re doing it!
