Cats are very poo-ticular and the potoroo s loo helps the gum tree grow. Worm poo is pure organic humus which helps keep the soil clean and fertile. Plankton pwooze feeds the animals of the deep-ocean. Chicken pwoo pollutes the countryside, along with waste from other farm animals. Nature s bin-men , moulds, toadstools, bacteria and dung beetles do their best to keep the place clean and the soil replenished with nutrients.
Humans have sewage works, but still dump billions of tonnes of unrefined poo into the seas.
One-third of all the world s productive soils are turning into deserts. They could be diverse farms, with animals living more natural lives, surrounded by forests and wetlands. Then the poo cycle would operate properly. Prof. David Bellamy, botanist, writer and broadcaster, is one of the best known and respected scientists in Britain. His television and radio broadcasts communicate his enthusiasm and concern for the natural world.
