What Caused "Day Zero"?

Image
Everyone agrees that water is a necessity. In Maslow's hierarchy of needs, it is one of the first things that people need to survive in this world. What happens if all of a sudden, people have to cut down the amount of water they take in for both drinking and cleaning? The obvious answer is outrage, riots, and panic. That is what is currently happening in Cape Town. Because of a 3-year long drought, previously full reservoirs are running out of water to keep the cosmopolitan city running. The people are complaining. They pay taxes to live comfortably, but in return, they have to minimize their water intake to make sure everyone gets enough water for the day. There is a projection in mid-July called "Day Zero", or the day when most of the city's taps will be turned off to conserve water. What caused this tragedy to occur? Two words: climate change. According to National Geographic, about a decade ago, the city was warned that its current population growth and sh...

Carbon Dioxide - From Global Pollutant to Important Energy Source

Scientists have discovered a way to turn carbon dioxide (CO2) into useable energy! The harmful gas that exits our cars, bodies, and factories has the potential of powering the objects we use daily. Researchers at the U.S. Department of Energy has discovered a new and unconventional catalyst for the reaction that converts CO2 to carbon monoxide(CO). According to an article in science daily, carbon monoxide can be used to make a wide range of beneficial elements from hydrogen to alcohols.  The problem that scientists are having is that until recently the elements that can catalyze such a reaction efficiently are the rare and expensive noble metals such as gold and platinum. However, researchers have discovered that single atoms of nickel - which is more abundant and less expensive - can be used for the same purpose. Both carbon dioxide and carbon monoxide are dangerous to humans and the environment alike. But if researchers can find a way to harness the potential energy of these...
