2005 and Vital Signs
2003 are compiled here within this online portal.
Fish is the last wild meal in the human diet, but roughly two-thirds of the world's major stocks are now fished at or beyond their capacity, and another 10 percent have been harvested so heavily that populations will take years to recover.
According to the World Bank, less than one-fifth of all countries arecurrently on target to reduce child and maternal mortality and provideaccess to water and sanitation, while even fewer are on course tocontain HIV, malaria, and other major diseases slated for reductionunder the United Nations' Millennium Development Goals (MDGs).
In 2004, weather-related disasters caused nearly $105 billion in economic losses (in 2003 dollars)—almost twice the total in 2003.Roughly 12,000 weather-related disasters since 1980 have caused just over 618,200 fatalities and cost a total of 1.3 trillion.
In 1950, U.S. drivers covered some 588 billion kilometers (365 billion miles) in 40 million cars, or almost 14,600 kilometers per car. By 2003, the average distance driven per year had grown to more than 19,000 kilometers.
The world's airlines use some 205 million tons of aviation fuel (kerosene) each year, producing greenhouse gases such as carbon dioxide, nitrogen oxides, ozone, sulfur dioxide, and methane. Jet fuel is the second-largest expense to airlines after labor and can amount to 20 percent of companies' operating expenses.
In the United States, cyclists are 12 times more likely than people in cars to die en route to their destinations. On a per-kilometer and per-trip basis, U.S. cyclists are twice as likely to die on the road as German cyclists, and more than three times as likely as Dutch cyclists.
Countries continue to lose more trees than they regenerate. Global forest cover stands at approximately half the original extent of 8,000 years ago. According to the U.N. Food and Agriculture Organization, an average of 9.4 million hectares of forest (roughly the size of Portugal) was lost annually during the 1990s.
How many people perish during warfare? Tallying combatant deaths is a narrow approach, since both military personnel and civilians are killed in battle.
By 2020, people in industrialized countries will consume 90 kilograms of meat a year—the equivalent of a side of beef, 50 chickens, and one pig. Worldwide meat production continues to grow, with an estimated 258 million tons produced in 2004, a two-percent increase from 2003. Since the 1970s, meat production has more than doubled because of higher demand and the introduction of large-scale production processes.
A study by the U.S. National Center for Atmospheric Research found that rising global temperatures have been a key factor in increasing drought worldwide. Carbon emissions from fossil fuels are believed to be the main factor behind the rise in atmospheric concentrations and global temperatures. Nearly three times as much carbon was released in 2004 as in 1960.
