Fracking, also known as hydraulic fracturing involves the extraction of natural gas from deep below the ground. A shaft is drilled into the ground followed by a horizontal well hole that flows to the gas layer of the earth. The well is divided into smaller sections and these sections are fractured in sections. Fracking fluid (7 million litres of water is used, several thousand tonnes of sand and 200,000 tonnes of chemicals (de Rijke, 2013)) is then pumped into the ground at high velocity. Cracks

Renewable Energy Sustainability According to the United Nations, the world reached a population of 7 billion people in 2011, and it is estimated that the world population will increase to 9.7 billion people by the year 2050. Due to the lifespan of the average person increasing by almost thirty to forty years within the past sixty years, the population is growing faster than the Earth can possibly sustain everyone. The current main sources of energy are still nonrenewable resources. Nonrenewable

Arjun Makhijani, a prominent researcher for The Institute for Energy and Environmental Research, claims that today’s emission rate of carbon dioxide is about nine gigatons annually and that the Earth only has the capability to absorb 3 gigatons annually—thus a problem arises. Furthermore, Makhijani states that about 2/3rds of the carbon dioxide emissions are caused by the burning of fossil fuels such as coal and petroleum. With those shocking statistics in mind, fossil fuel’s emission of carbon

disadvantages as an energy source. The use of fossil fuels, as an energy source, impact the environment as well as social, economic and political aspects of the world. Fossil Fuels; Beginning of Existence The existence of fossil fuels stem from the Carboniferous Period in time (U.S. Department of Energy, Fossil Energy). According to an article from Energy Source the creation of fossil fuels came about when “prehistoric plants and animals died” and then buried under the Earth for millions of years (Fossil)

Introduction: At the beginning of the movie, there were scientist, Dr. Grant and Dr. Sattler, who had a very big inspiration on Dinosaurs and Extinction of Dinosaurs. Grant and Sattler were invited to a weekend to see actual live dinosaurs at Jurassic Park. Meanwhile, having a good and educating trip, they found out how the embryos and dinosaurs were actually made, and no, they didn’t agree with the way things were being done. One of the workers, Nedry, shut down the park so he could get the 1.5

Introduction: “Limulus polyphemus, the horseshoe crab, inhabits shallow-brackish marine environments ranging from the Atlantic Ocean along the North American coastline to the Gulf coasts of the United states and from the East coast of Mexico to the Yucatan Peninsula” (Walls, Elizabeth). There are three other species of the horseshoe crab worldwide: Tachypleus tridentatus, Tachypleus gigas, and Carconoscorpinus rotundicauda that closely resemble Limulus in structure and habits, ranging from the

Rocks associated with the Viluy traps include dikes, sills, and layered basalt breccia, and are overlain by Late Devonian-Early Carboniferous sediments (Ricci et al., 2013). Previous analysis on dating the traps has proved difficult due to high rates of erosion and burial by Mesozoic sediments in the east and Siberian traps to the west (Kiselev et al., 2006). The current extent of the

1. Introduction Since1970, Muirshiel Country Park has been part of Clyde Muirshiel Regional Park which is situated in the River Calder Valley north of Lochwinnoch. The park is an area of general natural beauty with beautiful landscapes and great scenic views but people are allowed to live and work within the area. It may look remote but it has a purpose for human activity, as in the past the land has been used as a farm situated close to the current entrance, for field sports such as grouse shooting
