1. Because most people replace (replace) their mobile phone every two years or less, about 125 million phones are thrown (throw) in the bin every year in the USA. The problem is that many mobiles contain (contain) dangerous metals, like lead, mercury and cadmium, so if they are thrown (throw) away they pollute (pollute) the environment. Now, organisations like 'Call2Recycle' offer (offer) to take your old phone for recycling. Your old phone is collected (collect), and then it is sold (sell) back to the company that made it. Then either it is sold (sell) again in another country, or it is taken (take) to pieces for the materials, like plastic, glass and metal, and the electronic components.
