Keep an eye on what you are driving, and make sure you are keeping its pollution levels law. It is required by law, but its surprising how many people don’t really care.
Avoid using vehicles for going around the corner. The walk will do you good.
Use shared vehicles and public transport where possible. Use eco friendly fuels.
Keep an eye on what you are using. Many chemical products are harmful for the environment. Find out the effects of chemicals you use, and explore options that help you do your thing with minimum damage. Its probably healthier for you too.
Avoid cooking fires. Avoid campfires. Avoid all unnecessary smoke.
Don’t sit on the horn when traffic comes to a standstill. Your horn cannot physically move cars along. If it’s a jam, it’s a jam. If it looks like its going to take a while, switch off your engine, and have patience. Blaring horns only make a bad situation unbearable. Yeah call me fussy. I call it noise pollution.
This goes for other noise pollution stuff too. Bizarre loud celebrations in the middle of the night, loudspeakers, etc. near hospitals is a baaaaad thing to do.
