Listening To Volcanoes
Volcanoes are complicated, and we don’t have universally applicable ways to predict when they might erupt. Measurements of seismicity, gas emissions and ground deformation are all useful in trying to figure out what volcanoes are up to. However, it is unlikely that will ever have definitive prediction techniques.
How Safe Is Drinking Water?
Water is life. It’s a fundamental need for every human being on the planet. Each person requires more than five gallons of clean and safe water a day for drinking, cooking, and keeping clean. Dirty water, on the other hand, can be deadly. An estimated 1.8 million people die every year as a result of diarrheal diseases like cholera. And tens of millions of people are seriously sickened by water-related maladies.
The Changing Face Of Air Pollution
Air pollution in cities is a global problem that has reached crisis proportions in places like China and India. In our country, since the Clean Air Act was passed in 1970, there has been a great deal of effort exerted in controlling pollution from vehicles. A combination of pollution-limiting changes to engines, fuels, and pollution control systems has significantly reduced the amount of air pollution associated with the transportation sector.
Fracking And Streams
Hydraulic fracturing – better known as fracking – is a method of extracting oil and gas from shale deposits in which millions of gallons of freshwater and chemicals are injected into deep underground deposits. There has been a great deal of concern related to the effects that this process has on water quality and also on the stability of the ground in the vicinity of where it takes place.
Climate Change Threatens the U.S. Military
According to a new study from the Pentagon, nearly half of United States military sites are threatened by wild weather linked to climate change. The U.S. Department of Defense states that drought, wind, and flooding that occur due to reasons other than storms topped the list of natural disasters that endanger 1,700 military sites around the world – everything from outposts to large bases.
