Recycling is important because it allows materials like plastic, glass, and metal to be reused rather than thrown away. This saves significant amounts of energy and money - for example, energy recycling could provide 40% of the US's electrical needs and save $70-150 billion per year. However, Americans still dispose of too much recyclable material, with only around 23% of glass and 7% of plastics being recycled. Increased recycling could create more jobs and reduce waste in landfills, which contaminate soil and water supplies when trash decomposes. Events like Earth Day aim to raise awareness of environmental issues and encourage individuals to do their part through small actions like proper recycling.
