[单项选择]

Wherever people have been, they have left waste behind, which can cause all sorts of problems. Waste often stinks, attracts vermin and creates eyesores. More seriously, it can release harmful chemicals into the soil and water when dumped, or into the air when burned. And then there are some really nasty forms of industrial waste, such as spent nuclear fuel, for which no universally accepted disposal methods have thus far been developed.
Yet many also see waste as an opportunity. Getting rid of it all has become a huge global business. Rich countries spend some $120 billion a year disposing of their municipal waste alone and another $150 billion on industrial waste. The amount of waste that countries produce tends to grow in tandem with their economies, and especially with the rate of urbanization. So waste firms see a rich future in places such as China, India and Brazil, which at present spend only about $ 5 billion a year collecting and treating their municipal waste.A. Waste is everywhere
B. Waste is very harmful
C. Waste should be treated universally
D. Waste can be an opportunity
