Low impact development

According to King County Stormwater Services (2015), stormwater runoff accounts for approximately 1/3 of the water pollution in the Puget Sound. Contaminates like oil, pesticides, soaps, and industrial waste wash in to our local watershed where they negatively impact the local fish population and affect the supporting industry (Narayanan, 2013). Because of the unnatural rate and volume of stormwater flows it can damage wetlands and cause local flooding (Howard, 2007). The Pacific Northwest regularly receives a substantial amount of rain and snow melt. During these periods of heavy precipitation the volume of water is unable to seep in to the ground efficiently and runoff is created. Runoff is when the water travels across the ground surface and flows in to storm drains, streams, or other direct routes to significant water sources. As researchers May, Horner, Karr, Mar, and Welch state, urban development increases the amount of impervious surfaces which, while it does not contribute to pollution, alters the physical behavior of water systems (May, Horner, Karr, Mar, & Welch, 1997). This runoff behavior transports untreated pollutants on the…

These strategies include, effective communication, hiring of a diverse workforce, hiring appropriately skilled people, and finally offering development and training programs. Whether verbal or non-verbal, Proper communication can bring about an employees acceptance of the vision, values, and polices of a company. Failure to establish healthy communication can lead to poor work culture. Diversity within the work force is an important factor because a diverse population within an organization is…

extinction happened because of the impact of a cosmic asteroid and created a massive explosion…

and our exploitation of the earth. In each of the book’s thirteen chapters, Kolbert highlights a particular species that is now extinct and analyzes the causes and effects of its extinction. She explains the scientific history of the concept of extinction. Just as the current concept of a sixth extinction seems impossible to grasp, once the idea of rapid extinction itself was believed to be impossible. It took centuries of paradigm shifts in order for the scientific community to take the notion…

Dinosaurs, a dominating specie living in the Earth long time ago, extinct mysteriously. Paleontologists and scientists have established a variety of possible theories to explain. However, all these theories are still debatable.There are four main possible explanations: Asteroid Impact, Volcano Eruption, Falling Tide and Asteroid Impact theory was established by Luis Alvarez in 1980.Many plants and animals were disappeared abruptly from the fossil record as one moves from layers of rocks…

Stage 1: What caused the Chicxulub Impactor to enter the Earth’s atmosphere and hit Earth (2) About 65 million years ago an asteroid that is roughly 10 kilometres across, hit Earth on the coast of the Yucatán Peninsula in Mexico. It caused a huge explosion and left a crater that is about 185 kilometres across. This asteroid impact is commonly known to be the reason for the extinction of three quarters of the dinosaurs. (4) The asteroid soared through the sky at more than 40 times the speed of…

by Alexander, “Tourists now enjoy the sunshine and warm waters here, but 66 million years ago, it was dinosaurs that claimed their place in the sun” (Alexander 2). The asteroid also caused other chaotic events when it struck the surface of our blue and green planet. As said by Reynolds, “The consequences for everything in the region were terrible, and a years-long nuclear winter kicked dust into the atmosphere, ignited global fires, and played havoc with life on Earth” (Reynolds 1). The asteroid…

several million years the increased volcanic activity could have created enough soot and dust in the air that it blocked out the sunlight creating the cooler more varied climate that came with the Cenozoic Era. This seems like a very logical reasoning to why the climate would change but both the other hypothesis have a reasoning as well, the plate tectonics hypothesis suggest that there was a rearrangement of the continental plates that were occurring around the K-T boundary and this changed…

It is a common believe that mass extinction on our planet arose as a result of excessive warming and a deep acidification of the oceans. The asteroid theory states that the asteroid impact might have led to vaporization killing dinosaurs on the way. Dr. Keller’s hypothesis states that volcanic activity created a cascade effect that ended up in the extinction of these animals. Either way, experts commonly agree that dinosaurs could not survive in very hot environments. But how did extinction…

for the mass extinction of the non-avian animals of the cretaceous period. This theory I think would go directly and support with the Asteroid Impact theory. But there could also be other triggers that caused this, perhaps volcanic activity. Aside from the volcanic activity triggers, and the fact, that there have been no fossil records, of any kind postdating the late cretaceous period with fossils, eggs, footprints, etc. leads paleontologist to believe that “something” caused the demise of the…
