I understand MORE than I will explain!
Hang in there, all there is to do sometimes!
Experience is the best teacher. At least it used to be.

I feed my neps by recycling livestock from my aquarium and use tapwater for all my plants.(it's rlly pure here)
If you mean in general, i insulated my whole house, buy only the most energy efficient appliances, bring my own shopping bag, do 95% of my travelling by bicycle, separate all my garbage etc...
