My two cents...
Due to this pandemic, I'm finally eating the way I've always intended to. Beans, legumes, brown rices, chilis, stews, novel flours, baking.
I've dropped 30lbs, now close to my ideal weight. I'm also eating non-stop, so it's not due calorie restriction.
To maximize social distancing, and maybe reduce risk of food shortages, I've been buying bulk as much as possible.
Another unexpected benefit is my food waste is now super low.

On a personal level, online calculators tell me I've reduced my footprint about 90 percent. More than the material change, I didn't expect it would improve my life so much -- saving money, time, increasing connection to family and control over my career, plus being invited to communities like food deserts who can benefit most from such transitions. I would bet most Americans could reduce about 70 or 80 percent with simple improvements they wish they did earlier. Most Silicon Valley types maybe 90 percent before any difficult decisions.
My podcast and nonprofit's missions are to help people realize they'll like the change. Everyone presents sustainability as a burden, chore, or sacrifice. In practice, it's the opposite, but no one tries so haven't experienced it. They think not flying means not working or seeing their family.
We're creating systemic change by leading well-known people to change, publicly so listeners have role models. Community influences people more than facts and figures, so we're focusing on people in everyone's communities.
Many opportunities for rewarding change.
