Plastic bags are a very common and dangerous type of pollution. It’s not just the ocean that is filled with plastic bits, but it is also hitting very close to home for us. A recent study of the Great Lakes found plastic concentrations ranging from 600 to 650,000 pieces per square kilometer. In the marine environment plastic bag litter is lethal, killing tens of thousands of birds, whales, seals and turtles every year as they often mistake plastic bags for food such as jellyfish. After an animal is killed by plastic bags its body decomposes and the plastic is released back into the environment where it can kill again. Each year, an estimated 500 billion to 1 trillion plastic bags are consumed worldwide. That's over one million plastic bags used per minute. We need to put a stop to plastic bags and bring our own reusable bags to the store.
