Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products. Recycling is vital in conserving natural resources and greatly contributes towards improving the environment. Recycling helps to enhance the sustainability of resources such as iron and plastic since recycling reduce the amount of waste into the environment. Those wastes can lead to pollution such as air pollution and water pollution. Recycling also conserves natural resources such as wood, mineral and fossil fuels because materials are reused. Recycling metal, plastic and glass decreases resource depletion, and reduces the ecosystem destruction of mining, drilling and deforestation.
