The document discusses reducing environmental problems through the 3Rs - Reduce, Reuse, and Recycle. It defines each of the 3Rs and provides examples. Reduce means living more carefully to create less rubbish and avoid waste. Reuse means using an item more than once rather than disposing of it after single use, like reusing glass containers. Recycle means processing used materials into new products to save resources and energy, like recycling paper. The document encourages applying these strategies like using online materials instead of paper excessively, and looking for minimally packaged products when shopping to help reduce environmental problems.
