Interesting choice. I just tell people this:

Life is like a garden. Some are flowers and some are weeds. Humans need to tend their own garden. They must be aware that what they do in their own garden does affect others.

More poetically:

My garden is planted

All natural soil

Heirloom breeds

Grown with pollution

In air & waterways

GMO’s in modern seeds

I’ve chosen to remove weeds

When they come up

Share with community

Even those who can’t see

The harm inflicted

- Gross Humanity
