If you learn and put into practice a SINGLE thing from my blog, it should be this: the most important work YOU can do to prevent mass extinction is not "Buy Different Product" or "Buy Product Differently."
Instead, it involves going outside and looking at the land immediately surrounding you physically and understanding that you have been appointed its protector, and then learning working contacting messaging organizing planting teaching informing organizing organizing organizing to take care of it.
There are old ladies with no email address in your community that are handing out more native plants than you knew existed, there are nature preserves and wildlife parks literally like on their knees begging for volunteers, you have neighbors and friends and acquaintances and family that you can teach and inform, there is at this very moment someone else in your community that would LOVE to start a community garden.
Learn to grow native plants and you can literally just hand them out to strangers for free and everyone loves it
I started volunteering at a nature center and now I have more contacts than I know what to do with. literally just look up anyone working in ecology or conservation in your area and email the crap outta them.
you can organize with members of your community to protect a vacant lot or a random pond or to put in foot paths or get rid of invasive species in a park or anything
