Where there are humans, there’s waste. About two billion tonnes of garbage was produced in 2016, and the amount we generate is increasing. A lot of it ends up in unmanaged dumps or landfill sites. Much of it can’t be reused or recycled, but instead of seeing it go to “waste” some cement factories are using it to create energy.
In this episode, People Fixing the World also looks at how tourists can help conservationists protect animals, such as lions, cheetahs and hyenas. All they have to do is share their holiday photos.
