answer:It means everyone picks at least one thing they can do to contribute to a better world. Very, very few people are able to give up driving, recycle every scrap of everything all the time, become self sufficient vegan farmers. My contributions fall into keeping my 5 acres chemical free, pesticide free, a haven for wildlife. I rescue geese and cats, consolidate my driving, and accomplish all errands in one trip to “town”, once a week or so. I do, however, enjoy a steak or other meat, once in awhile and don’t believe in any extremist path. Middle of the road and put your energies towards the things that you feel most passionate about. There should be no superiority trips going on, everyone does their little part, or multiple little parts. That’s the best we can do.
