Tattoo ideas

I would love to get another tattoo on my hand or wrist to symbolise my passion for the earth and everything in it (minus humans) I'm a vegetarian for animal cruelty reasons, have carried out conservation work in many countries and do all I can to preserve the world in which we insist on detroying. Would love some ideas of what to get, was thinking a tree but think that may be too common. (P.s I am normal honest 😝)
