We've been talking a bit about zoos this week, and we always love a good plastic bag discussion, and now here's something that combines both: a new art show at the Toronto Zoo that uses plastic bags to bring attention to the environmental issues facing the moon jellyfish.

Buffalo-based artist Kara Daving paints these lovely jellyfish on, yup, recycled grocery/retail bags that have been collaged together. The plastic bags mimic the shapes (and sometimes movements) of the jellyfish themselves, but the art also calls attention to an environmental issue. In addition to clogging landfills, plastic bags are also ending up in our oceans, threatening the habitats of many sea creatures and plant life -- including the moon jellyfish.

The art show ties in the with the new Great Barrier Reef exhibit , which opens tomorrow.

The show is in the Zoo Shop, which is past the admission gates -- which means it'll cost you the $20 zoo admission to see these paintings, which I wouldn't necessarily recommend. That said, they could be one more reason to head to the Toronto Zoo this month, if you were already thinking about it.

And they are definitely one more reason to start taking reusable bags to the grocery store.
