2016 Oil and Gas Lease/Sale on Montezuma County 's public health, ecological communities, and economic stability? Introduction Hydraulic fracturing, or fracking, is a technique often administered by oil and gas companies in order to create fissures within subsurface shale formations. After a site is established, the initial step entails breaking through the soil and stone via a bit placed at the end of a drill. As the drill moves through the rock layers, it utilizes air pressure to drive fragmented

Nowadays environmental pollution is one of the hottest topics in society. Ned Haluzan concludes,“The most appropriate definition of environmental pollution would be the introduction of different harmful pollutants into certain environment that makes this environment unhealthy to live in.”(1) In other words, the natural environment has been destroyed by human activities, and thus harmful to the phenomenon of humans and other organisms for survival and development. With continued increase in population，and
Fossil fuels in which it allows us to easily live and absolutely necessary part of everyone 's daily life. Origin of Fossil fuels Fossil fuels started millions of years ago before the dinosaurs first inhabited the Earth. According to Trefil and Hazen (2013), “that energy percolated outward to the Sun’s Surface: then, in a mere eight minutes, it made the trip through empty space to Earth in the form of sunlight” (p.53). During that time, organic materials such as plants and animals
Introduction This term paper is situated in an area of specific health related and environmental concern: the human dimensions of global change. For about a decade now there has been growing scientific interest in the global environmental changes resulting from anthropogenic activity. However most of this research has focused on the scientific bases of environmental transformations with little attention to how human social responses are linked to global change. As a result, scientists and researchers
sun exposure and its ultraviolet (UV) component, and also to do with society’s views that tanning is attractive and healthy (1). When sunlight goes through the atmosphere, all UVC and approximately 90% of UVB radiation is absorbed by the ozone layer, water vapour, carbon dioxide and oxygen. UVA radiation is less affected by the atmosphere; consequently, the UV radiation reaching the Earth’s surface is mainly composed of UVA and a small UVB (2). This essay will look into why sun protection is required
