I've been hearing a lot about how dangerous plastic is. Is it really that bad?

It depends on the type of plastic, and where it's being used. Some types of plastic are made from petroleum products and can be harmful to marine life if they're released into the ocean. Other plastics are biodegradable and can break down in landfills or oceans over time. Still others have been designed with additives that make them more resistant to breakdown. Ultimately, it's important to consider the entire lifecycle of any plastic product before deciding whether it's safe for use.
