Let me tell you about your generation, people in your 20s. You like brunch. You're not sure what you're doing with your life. You give a shit about the future of the planet. And you have tattoos. Shhhh. You have tattoos. I won't tell your grandma; it's cool.
Conservation nonprofit Tatzoo will not give you brunch (as far as I know), but it can help you with the other things. Apply for Tatzoo's training bootcamp, and the organization will teach you crucial skills for becoming a leader in conservation activism. Each team at the 10-week training camp will work to preserve an endangered species, gaining experience in fundraising, organizing, and communication along the way. And at the end of the program, you get a tattoo of the species you've helped work to save.
