In his book, The End of Plenty - The Race to Feed a Crowded World, Bourne chronicles the trends, making it likely we'll see more hunger and malnutrition in coming decades.  While the earth's population and economies are growing rapidly, our ability to feed it is undermined by climate change, growing water shortages, the use of farmland to grow biofuels and the increasing consumption of meat, which is a highly inefficient way to use the grain we grow.

Michal Biskup

This week, KPCW is proud to announce that Michal Biskup is the winner of the KPCW Water Waste Contest.

Twelve-year-old Michal found his entry while on his way to a school sport:

"I took this photo while I was biking to soccer practice, when I passed Ecker Hill Middle School, I noticed that the sprinklers were set up so that they watered the concrete more than the grass. this is a problem because less water got to the plants and more got to the concrete, where it would evaporate or go into a sewer.
