Answer:
Laptops (wrote this myself, not copied)
Explanation:
Laptops are ubiquitous in our everyday life. I couldn't even write this without one. The number of computer units shipped has increased from 135 million in 2000 to 355 million in 2011! When a laptop becomes useless, it is usually disposed of. Environmental Protection Agency estimates that only 38 percent of computers in 2009 by weight were recycled. A laptop can contain mercury, lead, chromium and other heavy metals that provide power. If these toxic elements ended up in a landfill, they could contaminate groundwater, surface water or the soil around the landfill.
Approximately 164 million people in the US own laptops. The amount of energy (electricity) needed to power these laptops contributes to the millions of tons of greenhouse gases that are transmitted into the environment.
Richard Mattison, CEO of the Trucost, part of S&P Global, stated, "Our analysis indicates that, on average, if nature charged for its services, the “true cost” of a desktop computer would be around 6 percent higher than the retail price, while the laptop would be 14 percent more expensive." In other words, if nature charged for its administrations, the "genuine expense" of a desktop, it would associate with 6 percent higher than the retail cost, while the laptop would be 14 percent more costly.
