Plastics finding their ways into ecosystems is a growing global problem. Increasing human usage of plastic products and irresponsible disposal practices puts many animals in harm’s way, as they are not biodegradable and consumption of plastic objects is often times fatal. However, a new study has found that urban bees have found a way to utilize the plastics found in their environments. A study conducted by the University of Guelph, found that urban bees have begun using discarded plastics, such as disposable plastic bags, to build their nests and that some colonies utilize building materials such as caulk and sealants in place of normal plant resins. Surprisingly, no ill effects to the bees have been reported. While the findings are encouraging in that they showcase nature’s adaptability, they are alarming in that they bring to light the extent of human influences on urban ecosystems.
