Design a memorial to remind people of you.
Go somewhere you like that is in danger of disappearing or changing forever. What is threatening to kill this place? Take photographic evidence and submit it to your local authorities.
Next time you find a dead animal, draw a white line around its body and find out who killed it, how, when, where, and why.
Stop and reflect. Take some time to create a map of your emotions.
Don't die before marking this mission complete!
