The Environmental Impact of Fisheries and Fish Farming on a Global Scale - Research Paper The Environmental Impact of Fisheries and Fish Farming on a Global Scale On our Oceanography class trip to La Jolla, California, we spent a day on the Ocean Institute boat running tests and observing sea life. To collect a sample of the different fish in the area we dragged a large net in the water, which the volunteers said they don’t do often because it is destructive to the environment. I found it interesting that catching fish in this way could be harmful not only to the fish, but to the ocean environment itself....   [tags: Ecology]

A Study of the Impact of Human Encroachment on Coastal Microbial Concentrations - Introduction: The intent of the study was to analyze the impact of human encroachment on concentrations of the bacterium known as enteroccocus in coastal waters. In order to evaluate impact of human encroachment, the research question, to what extent does the level of human activity and development in proximity to a saltwater source affect the levels of the bacterium enteroccocus present, was posed. This study is was undertaken because the United States recently changed the federal standard of water quality at state beaches from fecal coliform to enterococcus....   [tags: Ecology]

The Green Gap: Exploring the Divide Between Ecological Thinking and Acting - Most Americas with any media exposure know the ecological damage our society is doing to Earth, yet we have accomplished almost nothing to mediate it. This gap between knowing and acting seems counterintuitive. Commonsense tells us that once we know something is bad, steps are taken to prevent it. Prevention is all the more relevant because Earth is a dynamic system where impacts on one side of the planet are felt on the other. As my mother always quoted to me, “Commonsense ain't all that common.” This paper looks at the potential rationals of why we often believe in the ecological damage we are doing, but fail to act to fix it; the “Green Gap” as it were....   [tags: Ecology]

Policy Evaluation of the REDD Mechanism in the Congo - Introduction Deforestation in tropical forests has gained salience in public debate on climate change mitigation policies. Such salience stems from the negative externalities caused by deforestation, such as the release of greenhouse gases emissions, the loss of biomass, forest degradation etc. Recent research on CO2 emissions point out that tropical deforestation represents about 15 to 17 percent of anthropogenic emissions of carbon dioxide (CO2) . To curb the emission of greenhouse gases emissions from tropical forests, the parties to the United Nations Framework on Climate Change Convention have initiated a mitigation policy called “REDD+” (Reduction of greenhouse gases emissions from def...   [tags: Ecology ]

It is sad to say but humans have played their part in deteriorating the earth. We have polluted and killed the very thing that takes care of us.

Ocean Dead Zones - When referring to Arizona’s water Kris Mayes, chairwoman of the state’s utility regulatory panel once said, “How do you say just how valuable water is in an arid state like Arizona?” she said. “It’s like the credit-card commercial-it’s priceless” (McKinnon). She was right, because in a dry state like Arizona, water is pretty important. To say water is ‘pretty important’ for the world is an understatement. We use water to function.

Oceans in Crisis - Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth....   [tags: Ecology ]

Mankind has had many impacts on the ecosystem – rapid development, depleting natural resources, overhunting, and pollution of various kinds- all of which have resulted badly for other species within our world.

Insecticidal Efficacy - Hussein (1991) reported that the use of Tween-80 and Span-80 surfactants as synergistic agents had improved the insecticidal efficacy and lowered the LC50 values from 3.3 to 5 times in case of Cyphenothrin and from 3.2 to 5.7 times in case of fenitrothion. Tween-80 was found more effective than Span-80. The combination ratios between the insecticides and the surfactants are important in determining the insecticidal efficacy. Abdel-Rahman et al.

Wetlands are defined as geographical areas where water covers or overly saturates the soil during the majority of growing seasons (CZM). They vary based on their appearances and locations which are greatly influenced by regional and soil divergence such as topography, climate, water chemistry, vegetation as well as human degradation (CZM). Wetlands are identified based on three major attributes: the constant availability of water (hydrology), the presence of specially adapted plants (hydrophytes) and the developmental condition of the soil (hydric) (CZM)....   [tags: Ecology ]
