This document discusses biodegradable plastic bags and bottles. It explains that biodegradable means a substance can break down into simpler substances through living organisms and will not persist in the environment. It describes how plants and woods are mixed with chemicals to make biodegradable products that decompose over time, returning to nature. Normal plastic dumping pollutes water and air, spreading bacteria and disease. Biodegradable plastics degrade where they can be digested, reducing litter and environmental harm. Such bags and bottles decompose from temperature changes or bacteria, leaving no pollution. Their price is the same as normal bags and bottles and they are marketed through social media, free samples, and branding to prevent pollution and support healthy living.
