.com was taken. which should I go, .net, .io, .co or any other suggestions?

I have an idea of a web tool to help people go ethical and healthy eating habit. .com was taken😢

The audiences are 16-35 yo people who are interested in starting vegan/vegetarian diet or consume less meat.

the domain honestly doesn't matter but based on your target, I'd go with a .co (or even .app).
.net is from the 90's and .io it too "techy"

Thank you 🙏 .app sounds like a good idea, too!
