1. Partridge means that humans have moral responsibilities towards people that they do not know individually and who may not even exist at the present. He uses a metaphor about a campsite to explain his argument: when they have finished camping at a campsite, a person has a moral obligation to clean it for the next person who will use it. While they do not know this person, they still have good reason to believe that someone will eventually come to use the campsite in the future and that by not…

Meanwhile sustainability is the ability of the earth’s natural systems, cultural systems, and economic systems to survive and adapt to changing environmental conditions indefinitely in the face of exponential population growth. In class we studied five ecosystems that were vital to resource sustainability and the continuance of life on planet earth. These five cycles we studied were: the water cycles, the carbon cycle, the nitrogen cycle, the phosphorus/ rock cycles, and the sulfur cycle.…

Water Pollution All around the world, many plants, animals and people are dying because of poor water conditions. On top of that, many ecosystems, both land and aquatic are being destroyed by the dumping of toxic materials. Fresh water is already very limited in the world today without pollutants included in it. More than half the developing world does not fresh, clean water to drink. Water pollution shrinks the amount of clean drinking water for everyone. Aquatic life is also being majorly…

(National Wildlife Federation, 2016, p.1). 1. What kinds of problems can invasive species cause? Do you think one group of invasive species is worse than another? Why, or why not? Some of the problems that invasive species cause is impacting natural ecosystems, the economy, recreational, agricultural, and commercial activities. Invasive species can also effect human health. Removing invasive species can be costly. Invasive species also prey on native species, cause or carry disease, prevent…

suggests that terrestrial food webs, which are depictions of biodiversity, species interactions, and ecosystem structure (Polis & Strong 1996), are dramatically altered following plant invasion (DeVore & Maerz 2014; McCary et al. 2016; Smith-Ramesh et al. 2016). For example, successful plant invaders can eliminate vital plant-herbivore linkages, resulting in transformed food-web interactions and ecosystem structure (Carvalheiro et al. 2010; Engelkes et al. 2012). Invasive plants can also alter…

Introduction: Urban areas contribute pollutants that wash off of areas that are not native to the area (Sanders, et. Al. 2001). These pollutants caused by urban areas contribute the deterioration of water quality in stream and runs which make up a significant part of the bodies of water in the state of Ohio. Water quality is crucial for the fish and macroinvertebrates species that can sustain a community in that specific body of water, any change in this quality can change the entire diversity…

Task #7 My ecosystem has been affected significantly by humans both positively and negatively. The positive impacts have led to increasing the diversity of species as well as attracting civilians. Throughout the recent years, different kinds of fish have been added to the lake. This has allowed the fish population as well as the lake diversity to increase significantly. The introduction of a new species to the lake provides many opportunities socially as well as environmentally. However, the…

The commons are the natural resources available to all members of a society or community. The natural resources include water, air, animals, plants. These materials are not owned privately, they are held in common. Hardin’s main assumption about the commons can be separated in three categories; the world is biophysically finite, over-population can be considered as an example of the tragedy of the commons, and the system commons for breeding must be abandoned. The tragedy of the commons…

Objectives of Dingle oceanworld: Dingle oceanworld is a center of research and conservation. The facility was opened in 1996. The mission statement of Dingle oceanworld is ‘To develop Dingle Oceanworld as a National and International Centre of Excellence in the care, conservation and presentation of all forms of marine life for clean seas. We will conduct research which enhances the quality of marine life and educate our visitors to the best of our ability.’(Dingle Oceanworld, n.d.) Why…

Presence of carnivores helps to maintain the integrity of ecosystems throughout the world (Soulè and Terborgh, 1999). Many carnivores are capable of altering trophic structure and biodiversity through a process known as top-down control (Elmhagen and Rushton, 2007). Through this, carnivores are able to prevent the overabundance of herbivores. If uncontrolled, an explosion in herbivore population density would increase the grazing pressure that would ultimately threat the survival of the…
