Concept

Key idea

Our environment includes the air, water, land, and living things around us. Pollution occurs when harmful substances or unwanted energy damage these surroundings. Smoke can pollute air, untreated sewage can pollute water, dumped waste can pollute land, and excessive unwanted sound causes noise pollution. Preventing waste is often better than dealing with it later. Reduce means using less and avoiding waste, such as taking only the food you need. Reuse means using an item again, such as a durable shopping bag. Recycle means processing suitable discarded materials into material for new products. Reusing a jar is not the same as recycling its glass. Separate waste according to the local collection system. Keep accepted recyclables separate from food waste. Suitable fruit and vegetable scraps and dry leaves can be composted with adult guidance. Other waste needs appropriate collection and disposal. Not every plastic item can be recycled locally, and not everything that breaks down belongs in a home compost bin.
