This quiz application from the Sierra Club shows you amazing things that happen in 24 hours in the natural world. How Much In A Day takes a different approach to quantifying the natural world. Focusing on meteorological forces, animal behavior (including that of humans), and other everyday phenomena, it exposes both the wonders and horrors that transpire on a daily basis. Sample : How many people are born worldwide in a day? Answer: According to the Population Reference Bureau in Washington, DC, as of mid-2004 about 368,000 people were coming into the world every day while around 158,000 were dying. That leaves the world with nearly 80 million additional people each year. A portion of this mobile application's sales proceeds are donated to the Sierra Club for environmental protection causes.
