Computers are in my opinion really great and there are millions of people around the work who either work in front of a computer or simply like spending time in front of a computer. You can also recycle computer parts if you want to do some recycling. Computers have been around for a few decades but they already completely revolutionized the way we live. It is hard to say how the lives of people will look like in fifty or so years, but I am sure that computers will be even more popular. Computers allow people to save time so no wonder that they are so popular everywhere.
