Yes. PCs require energy to run, which typically comes from coal-burning power plants, releasing CO2 and contributing to global warming. Most PCs also have features that use “standby power,” which means they continue to emit CO2 even when switched off as long as they’re plugged in.
PC manufacture and shipping also releases CO2 and uses up water. Finally, many of the metals used in computers are toxic, so if they are not disposed of properly and sent to a landfill, they will leak toxic chemicals into the earth and groundwater.
In addition to the issues listed above, electronics disposal and recycling is becoming an ever increasingly important issue, especially as a projected 400 million electronic equipment units will be discarded as obsolete annually in the next decade. As mentioned above, recycling these materials is very important because of the potential toxicity of the metals and other materials in electronic equipment such as computers. Responsible electronics recyclers break down old computers, sell wiped hard drives, monitors, and CPUs, and break down other non-reusable pieces such as wiring glass, and plastic parts to obtain raw materials for use in new products. Considering all of this, if a personal computer is pitched into a landfill instead of being recycled, it is indeed creating a pollution problem that could be resolved with recycling.
If what you mean is do they produce invisible, odorless toxins, then the answer is no.
but the other two answers’ are right on the spot though. Google “e waste” and look at images. it makes me want to cry!! Reduce burning coal and use the power saver option on your computer, or at least turn the monitor off when you walk away for more than 20 minutes.
