Carnivorous Plants Changing Their Diets Because of Pollution

Who would have known that carnivorous plants would change their diet into becoming less bug eating plants to a more vegetarian diet instead. Nitrogen in the air is giving them enough nutrients apparently, and because of that they don't need to eat as many bugs as they once did.
The plants have cut down on eating bugs because they get enough nutrients from the soil. According to Dr. Jonathan Millet from Loughborough University, human activities like burning fossil fuels have upped the nitrogen in the air which gets dropped to the ground by the rain to be inhaled by the carnivorous plants' roots.
Plants in heavily polluted areas get 22% of their nitrogen deposition from bug eating, while plants in areas with light pollution get around 57% of their nitrogen from bugs. More than double!
Because of that, the study says that the plants are turning off their bug-eating ways by making their leaves less sticky and changing its colors. Read more about it over here: [Chem.info via Inhabitat]
