The document discusses the main uses and effects of plastic. It notes that over 500 billion plastic bags are used worldwide each year, most of which are not reused or recycled. Plastics are used in many applications like packaging, electrical goods, vehicles, and agriculture. However, plastics take thousands of years to decompose and release harmful chemicals. Their lightweight and durability also leads to plastic pollution in oceans and landscapes. Plastic pollution negatively impacts health through chemical exposure, and harms environments and wildlife through ingestion, entanglement, and chemical effects. The document outlines some ways to reduce plastic use such as favoring biodegradable and reusable products, increasing recycling, and avoiding single-use plastics.
