Environmental issues are harmful effects of human activitity on the biophysical environment. Environmentalism‚ a socialand environmental movement that started in the 1960s‚ addresses environmental issues through advocacy‚ education and activism. The carbon dioxide equivalent of greenhouse gases (GHG) in the atmosphere has already exceeded 400 parts per million (NOAA) (with total "long-term" GHG exceeding 455 parts per million). (Intergovernmental Panel on Climate Change Report) This level is considered

Value of Water Humans have never had to deal with problems associated with water pollution until now‚ when we have already caused irreversible damage and have run into major difficulties regarding water worldwide. Although we rely on this critical resource to survive‚ we have failed to take care of our sources and water pollution has increasingly become a large problem that humans must deal with. Water is a human’s most valuable resource and it is essential to every living species. Humans can survive

Précis – Water Follies Purpose: This text was written in order to bring light to the fact that as the science of hydrology has grown enormously in recent years‚ the legality that dictates how ground and surface water may be used has been stuck in the 1800s. Argument: There is a detrimental disconnect between science and policy regarding domestic water usage that encourages rampant misuse and exploitation. Glennon argues that the common property resource of groundwater urgently requires more

their spread has been called the "least reversible of all human impacts” (White‚ 1997). In the same way that “these invasions threaten biological diversity by causing population declines of native species and by altering key ecosystem processes like hydrology‚ nitrogen fixation‚ and fire regime” (White‚ 1997)‚ the insertion of technology on a people not culturally ready for it will force out the natural cultural timeline. Often this change brings about many more unforeseen and for the most part‚ harmful

Habitat Loss Habitat loss—due to destruction‚ fragmentation or degradation of habitat—is the primary threat to the survival of wildlife in the United States. When an ecosystem has been dramatically changed by human activities—such as agriculture‚ oil and gas exploration‚ commercial development or water diversion—it may no longer be able to provide the food‚ water‚ cover‚ and places to raise young. Every day there are fewer places left that wildlife can call home. There are three major kinds

frequently subjected to human modification since the early 1900s due to the high desire for development in beautiful coastal areas‚ resulting in these habitats being filled in‚ polluted‚ exposed to invasive species‚ and having drastic changes in hydrology regimes (USFWS 1999). Dahl and Stedman (2013) of the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service estimate that more than 80‚000 acres of coastal wetlands are being lost on average each

In Saskatchewan‚ to proceed with a development project‚ the Minister of Environment must approve of the project. Therefore‚ according to The Environmental Assessment Act‚ the Proponent‚ i.e.‚ the project’s developer‚ must conduct an Environmental Impact Assessment (EIA)‚ and the potential impacts must be organized in a document called Environmental Impact Statement (EIS). The EIS is submitted to the Environmental Assessment Branch (EAB) and a technical review is conducted‚ ensuring that the Proponent

Differential Equations and Statistics. Modern Geological Industries use Mathematics for almost all the exploration techniques. The application of Mathematics to problems in geology and mining as well as to hydrology date back a considerable time. For a time‚ geostatistics meant statistics applied to geology or perhaps more generally to problems in the earth sciences. The basic programs‚ or computer applications which are required by the geologists‚ are completely

Stretches of a river can be different in terms of their processes and landforms. Introduction: My investigation is a study of hydrology‚ as I want to find out how and why a rivers channel‚ flow and valley characteristics change as you move downstream from its upper course to its mouth. These changes are represented in the Bradshaw Model (fig 1)‚ a fluvial model that describes changes in the river channel and flow characteristics between different courses along the river. Based on three factors
