The "3Rs" stand for Reduce, Reuse, and Recycle. These principles help us manage waste and protect the environment. To reduce means to cut down on the amount of waste we create, like using less plastic or buying only what we need. This helps lessen the burden on landfills and conserves resources. Reuse involves finding new ways to use items instead of throwing them away. For example, you can turn an old jar into a storage container. Finally, recycling is the process of turning waste materials into new products, like transforming used paper into fresh sheets. Together, the 3Rs promote a healthier planet.
