Though Brazil's Amazon has been the focus of environmental groups for decades, the deforestation rate there has fallen dramatically in recent years as clear-cutting of Amazonian jungle in eight other countries has started to rise.
As a result, the 40 percent of Amazonia located in a moon-shaped arc of countries from Bolivia to Colombia to French Guiana faces a more serious threat than the jungle in Brazil. The culprits range from ranching to soybean farming, logging to infrastructure development projects.
Charlotte, N.C., host of the 2012 Democratic National Convention, is the nation's biggest financial center outside of New York. But Charlotte and surrounding Mecklenburg County have the highest foreclosure rates in the state, and many thousands of homeowners owe more on their homes than the properties are worth.
As thousands of Democrats converge in Charlotte for the convention, some troubled homeowners have also gathered, lamenting that the foreclosure crisis has not been sufficiently front and center in the presidential campaign.
The number of U.S. families struggling to put enough food on the table remains at record-high levels, according to new figures out today from the government. Last year, 1 in almost 7 households were what the government calls "food insecure." That's about the same level as in 2010, but still far higher than before the recession.
In addition to surveying the planets, the Voyager mission also spent time studying the planets' satellites, or moons. This mosaic image, taken in 1989, shows Neptune's largest satellite, Triton. Triton has the coldest surface temperature known anywhere in the solar system.
The Voyager 1 spacecraft's 35th anniversary is proving to be unexpectedly exciting, as scientists gathered this week to examine new hints that the spacecraft is on the verge of leaving our solar system.
Voyager 1 is now more than 11 billion miles away from Earth. It blasted off in September 1977, on a mission to Jupiter and Saturn. But it also carried a Golden Record filled with music and the sounds of our planet, in case it encountered intelligent life as it moved out toward the stars.
