  • Non Native Invasive Species

    For example, “Holland et all. (1995) identified the [zebra] muscles are the principal reason that eutrophication abated in Lake Erie, while others have noted similar effects in other lakes and rivers (e.g., Strayer et. al., 1999)” (Sagoff 2005). The significant reason why zebra muscles are taking over is due to competition for resources. The zebra muscles…

  • Coral Reef Bleaching

    Coral Reef Bleaching Coral reef bleaching, which is the whitening of diverse invertebrate taxa. The cause of the whitening is “from the loss of symbiotic zooxanthellae and/or a reduction in photosynthetic pigment concentrations in zooxanthellae residing within the gastrodermal tissues of host animals.” (P.W.Glynn) The reason why coral reef bleaching is such a concern is because the “consequences of bleaching large numbers of reef-building scleractinian corals and hydrocorals.”(P.W.Glynn)…

  • Coral Reef Deforestation

    between warming ocean waters and disease outbreaks, in that coral disease prevalence increased from winter to summer in all major families of coral. As stated before, coral disease is also instigated by insufficient water quality particularly due to eutrophication and sedimentation. Corals are only suited to cope with certain mild and controlled levels of nutrients in the water, as result when the water becomes too rich in nutrients, this has been found to accelerate disease signs in corals as…

  • Oil Seed Crops Case Study

    4. Discussion 4.1. Comparative analysis of oil seed crop The comparative analysis from the LCA of sunflower, soybean, and canola per impact category are shown in Table 2. According to the results reported in the table 2, soybean was the oil seed with the the best environmental profile regardless the impact category. In contrast, sunflower was the oil seed crop with worst environmental results in almost all the categories. Environmental results were same pattern for the three crops, but…

  • Oxygen Vs Intermolecular Forces Essay

    INTRODUCTION The determination of whether a body of water is fit for consumption and all other factors concerning its physical and chemical state is known as water quality. Water (H2O) has a covalent bond as it consists of two non-metal substances (intramolecular bond). Intramolecular forces are the forces inside an individual molecule (chemical bonds) while intermolecular forces occur between molecules (physical interactions). Hydrogen can act as a metal or a non-metal and oxygens bond with…

  • Carbon Dioxide Impact

    the whole human race is enough to fill a canal 10 meters deep, 100 meters wide, and 12.1 million kilometres long, long enough to encircle the globe 180 times. Impacts include water degradation, the depletion of rivers and groundwater as well as eutrophication when excess nutrients enter the water courses and cause algal bloom. Rivers are drying up because of greater agricultural production and water consumption and groundwater levels are declining rapidly, especially in densely populated areas…
