In my opinion per the current trends in the world, human population eventually outgrow the earth’s ability to sustain it, it probably won’t happen in our life time but it will. I have always been concerned about our water supply, especially so since what happen in Flint, Michigan, so I decided to do some research on our water supply. In this country, we have 4.5 percent of the world’s population yet almost 8 percent of its freshwater resources. It is home to the largest freshwater lake system in

Largest Explosion The area around Yellowstone has been home to some of the most pyroclastic explosions currently known to mankind. Based on rock layers found around Yellowstone and areas impacted by prior eruptions, scientists at the USGS (United States Geological

According to the United States Geological Survey, several flights fly over regions from Asia to North America so the ash cloud could indigne aircraft. "Ash and aircraft do not mix, as volcanic ash is abrasive, melts at jet engine temperatures, and can cause engine failure." Alaska Volcano

The purpose was to create a program and coordinate assets of the federal government and state agencies to “control and minimize the economic, ecological, and human health impacts caused by invasive species (Bergman).” In addition to organizing and establishing federal policy in regards to invaders it defines what an invasive species is.

Arizona, which is a few miles upstream from where the pulse flow was added at the Morelos Dam. Each data point represents the monthly mean streamflow rate (discharge rate) in cubic feet per second, from 1963 to 2016, as reported by the United States Geological Survey (USGS, 2017). The red linear trend line in Figure 3 shows the overall trend in the streamflow rate during this time period. To further our analysis of the history of Colorado River streamflow, we prepared a histogram, Figure 4, to determine

to a report from Newsweek Global, the Oklahoma Geological Survey states that Oklahoma only has one and a half earthquakes over 3 magnitudes per year before 2008, the year of the oil and gas companies begin to use hydraulic fracturing technology, compare to two and a half per day in 2015(MCGRATH). The United States Geological Survey (USGS) also indicates that hydraulic fracturing induce earthquakes on March 28, 2015 (MCGRATH). In addition, United States Environmental Protection Agency confirmed that

The year is 1964, what seemed to be just like any other normal day in southern Alaska turned out to be anything but.

What is known for certain is that on August 15th of 2012, people were on an island in the East China Sea which both the Chinese government and Japanese government

Origin-Destination (OD) models and to investigate their performance using location based social network data which is capable with the potential to provide traffic design with higher spatial and temporary resolution at lower cost than traditional methods of survey(Kheiri, Karimipour, and Forghani 2015). This data was applied to analyze the trip attraction for the
