The drought may be officially over, but we all found out there was no need to just waste a natural resource by keeping the water running while brushing our teeth, or taking a shower that is too long. Eliminate harmful cleaning products and use all natural baking powder for scouring, polish, or fungicide. Keep the air clean. Don't smoke. It's a disgusting habit anyhow, but do us all a favor, and just find something else to do instead of smoke.
Be kind to each other. The world and our planet is a better place if you smile. If someone insists on being right with road rage or some other ridiculous thing that may harm others, let it rest in their karma, not yours. Being a good friend is something that should be easy for us earthlings, and yet we rarely have time for each other.
Spay or neuter your pets. Having less can be better. We can care and give better lives to pets if we don't let them over-populate.
