Did you know? A bicycle is a marvel of engineering efficiency, one where an investment in 22 pounds of metal and rubber boosts the efficiency of an individual mobility by a factor of three. On my bike I estimate that I get easily 7 miles per potato. For more information view the text and data in Chapter 6 of Plan B 4.0: Mobilizing to Save Civilization.
Need data? Sometimes numbers can tell a story. Here are some of the figures from the behind-the-scenes research for the latest book from Earth Policy Institute, Plan B 3.0: Mobilizing to Save Civilization, by Lester R. Brown. Complete data sets and charts are now available.
Did you know?:
The eight warmest years on record have all occurred in the last decade.
For seven of the last eight years, the world has consumed more grain than it produced; grain stocks are now at a historic low.
One fifth of the U.S. grain harvest is now being turned into fuel ethanol.
One third of reptile, amphibian, and fish species examined by the World Conservation Union are considered to be threatened with extinction.
Grain yields increased half as fast in the 1990s as they did in the 1960s.
Life expectancy in sub-Saharan Africa today is lower than it was in the late 1980s.
Today’s economically recoverable reserves of lead, tin, and copper could be depleted within the next 25 years if their extraction expands at current rates.
Nearly half of the annual global military budget of $1.2 trillion is spent by one country—the United States.
But not all the news is bad:
South Korea leads the world in paper recycling, recovering an estimated 77 percent of its paper products.
Conservation agriculture is practiced on more than 100 million hectares around the world
