Cities across the world are growing, and so is the amount of rubbish they use. In fact, the citizens of London throw out more than 3.7 million tonnes of waste each year. That is the equivalent of over 1,500 Olympic-size swimming pools filled with rubbish!
Not only is the amount of properly disposed trash rising, but so is the amount of litter. City governments are desperately trying to find ways to keep their communities clean while also preserving the area’s space and aesthetic style.
