During the second half of the 20th Century, a consensus emerged among North American archaeologists that the Clovis people had been the first to reach the Americas, about 11,500 years ago. This is the way America got populated.
<h3>What are major changes occurred in America's population?</h3>
In 2006, America's population reached 300,000,000 inhabitants. According to the estimates of the US Census Bureau, at the end of 2019 the American population will exceed 330 million people. As can be seen, it is a population in constant increase, both for its positive birth rate and for the high rates of immigration that arrive in the country every year. With these numbers, a percentage of annual population growth of 0.62% is determined.
This amount of population makes the United States the third most populated country in the world, only behind China and India (which have 1.4 billion and 1.35 billion inhabitants, respectively).

The steps of hydraulic fracturing have been placed in order as follows:
1. The targeted shale formation is drilled to the desired depth
2. The well is completed
3. Production begins with oil and gas flowing and fracturing commencing.
4. Well abandonment which entails leaving the land as it was initially..
<h3>What is hydraulic fracturing?</h3>
Hydraulic fracturing refers to the process of injecting a well with chemicals and other materials that are needed for it to release its oil content. Hydraulic fracturing often begins with the preparation of the well to be used for the purpose.
Next is the drilling of the target area. This is followed by the completion of the well, and the beginning of production. After production is completed, the well is now abandoned or returned to the way it was when production began.
