Despite its importance to economic growth, environmental protection, and global health and energy issues, scientific literacy is currently low among American adults. According to the national survey commissioned by the California Academy of Sciences:
* Only 53% of adults know how long it takes for the Earth to revolve around the Sun.
* Only 59% of adults know that the earliest humans and dinosaurs did not live at the same time.
* Only 47% of adults can roughly approximate the percent of the Earth's surface that is covered with water.*
* Only 21% of adults answered all three questions correctly.
Knowledge about some key scientific issues is also low. Despite the fact that access to fresh water is likely to be one of the most pressing environmental issues over the coming years, less than 1% of U.S. adults know what percent of the planet's water is fresh (the correct answer is 3%). Nearly half didn't even hazard a guess. Additionally, 40% of U.S. adults say they are "not at all knowledgeable" about sustainability.
Despite this lack of knowledge, U.S. adults do believe that scientific research and education are important. About 4 in 5 adults think science education is "absolutely essential" or "very important" to the U.S. healthcare system (86%), the U.S. global reputation (79%), and the U.S. economy (77%).

I can kind of understand percentage for the question about dinosaurs and humans given that fundamentalist Christians teach that they existed at the same time to try and explain the idea that the earth is only 6,000 years old. However, how the hell can 53% and 47% of Americans get two of the most questions right? These are two things everyone should know. A person shouldn't even have to think about, they should just know the answer.
