If you’re looking to buy a computer and don’t want to spend a lot of money, a used computer may be the way to go. You can usually find one for less than half the price of a new one. Also, buying a used one can help reduce electronic waste. New computers require a large amount of resources to produce and ship, including raw materials, electricity, labor and fuel. In addition, manufacturing creates bad byproducts like air and water pollutants. Computers are also full of toxic chemicals like lead, cadmium and brominated flame retardants. The production of computer components also releases a large number of greenhouse gases. It takes hundreds of years for these devices to break down, and they leach toxic substances into the environment in the process.
