  34. Dirty Water
    Waste water from power stations, waste from factories, and fertilizers from farms that are sources of water pollution
  35. Cloth diapers
    An environmentally friendly alternative to disposable diapers that produce copious amounts of methane when disposed of in landfills
  36. 90%
    The amount of the world's waste that ends up in landfill sites
