Tell Me Tuesday: What green actions make you feel you're doing your part?

For example, even as I enjoyed the astoundingly beautiful weather on the long Thanksgiving weekend, I couldn’t help but feel a little guilty about what the unusually warm temperatures represented: climate change.  So while I was out enjoying a lovely hike on Sunday in 27* Celsius weather, I kept thinking about how this type of unusally warm weather could contribute to the loss of summer sea ice in the Arctic and how that would affect Arctic communities and species like the polar bear.
I don’t usually find guilt that productive, so I tried to find something positive to do for the environment.  And there on the hike was my answer: a field of milkweed pods just opening up.  For anyone who’s not familiar, milkweed is the only plant that the monarch butterfly caterpillars feed on, which makes it pretty special.  So when my friends and I saw an opportunity to help seed these important plants, we jumped on it!  Not only did we have a great time, but we hopefully helped feed future generations of monarch butterflies.  (And I think I finally got all the fluffy bits out of my hair today.)

All this made me curious: what conservation actions (however small) make you feel good about your contribution to the planet?
Last TMT: As it turns out, lots of you DO love sharks!  It’s great to hear that you find them “fascinating” and are glad “they are finally starting to get the protection they deserve.”  As always, thanks for the comments – please keep them coming!
