BOB DOUGHTY: ist">Archeologist Dorian Fuller of University College in London directed another study of climate change. He says the air began to suffer when people first started ising">raising farm animals like cows, goats, horses and pigs. When these animals process food, they produce a large amount of methane. is">This gas traps even more heat than carbon dioxide. He also says that growing rice in Asia added a large amount of methane to the air.
Some of these findings were presented recently at a meeting of the American Geophysical Union in Santa Fe, New Mexico. Other studies will be presented in the journal “Holocene” later is">this year.
Other than reducing the levels of these carbon gases, what can we do to help the environment? ists">Scientists agree: plant more trees.

FAITH LAPIDUS: “That
is
a curiosity! “ That is something that people in the southern United States often said when they saw something unusual that could not be explained easily. It also is probably what a number of reporters said earlier this month when they were permitted to see a machine that will be sent to the planet Mars. It is called a rover, and its name is…Curiosity. The reporters saw the machine at the Jet Propulsion Laboratory in Pasadena, California.
The name of this space vehicle came from Clara Ma, a student from Kansas. Two years ago, she won a competition to name the rover. She also plans to be at the launch area in Florida in November when Curiosity is sent on its way.
