These take forever to degrade - like almost never. What if we had enclosed areas on the ocean where they are floating on the water - in a net so that ocean life and birds can't eat them, but they reflect back the heat that the ocean normally absorbs. We could put these on land as well. As long as they are contained by a net, they will help reduce climate change. Even a little helps when everyone's ideas are adopted.
