Native flowers attract bees and offer pollen + nectar for them :)
Don't forget that honeybees aren't the only bees nor the only pollinators. Ask your local university or beekeepers / native plants association about what you can do to help out in your area!
Worker cooperatives (and often cooperatives in general) are an example of this. They almost always exist within a capitalist system, so are not able to completely separate themselves from all aspects of capitalism, but they are definitely examples of common ownership of means of production.
Specifically you can look up the Mondragon Corporation which is probably the biggest/best known example of a workers cooperative but there are many others. There are lots of variations on this same concept - one where risk, rewards, and decision-making are shared more equitably among everybody participating. I think the most interesting are food co-ops (and sometimes CSAs), utility cooperatives, and housing cooperatives. These are all over the place and are often quietly successful examples of common ownership.
