Read the following excerpts from an article published on earth.com and answer the question that follows. "As the movement against plastic straws continues to gain momentum, plastic balloons are getting their fair share of negative attention as well. A growing list of cities and states are banning mass balloon releases, and a few towns in Massachusetts have even banned balloons altogether. After balloons are released into the air, they can travel hundreds to thousands of miles before returning to the Earth as litter. In the ocean, balloons often cause fatal injury to marine animals who mistake them for food and ingest them. Dr. Jan Andries van Franeker of the Wageningen University & Research Centre explains why degradable balloons are not the solution to the problem. 'Animals mistake remains from balloons for food, which may cause blockage of stomach and intestines and may lead to starvation,' said Dr. Franeker. 'Latex rubber, in spite of its natural origin, does not degrade quickly enough to avoid ingestion by marine wildlife and potential damage to their digestive system.' States such as California, Connecticut, Tennessee, and Virginia have banned mass balloon releases and many people feel that these events should be banned everywhere, considering the fact that it is basically littering."
