As I reviewed the results and thought about the laboratory work up I came to the conclusion that I had to be careful with believing them.
There are some uncertain factors, which needed to be pointed out.
The first thing that came to my mind is, that during my measurements on the length of Fucus spiralis I was not sure which plants were complete and which not. This uncertainty comes from the way we sampled the Fucus spiralis. We had to hurry up and cut the plants with a knife but did not pay attention whether we were cutting the directly at the stipe or above.
Furthermore, we did not distinguish between fully grown plants and young ones.
This makes the results of the mean lengths not precise (in means of actual mean …show more content…
I think that this is a great example to explain how bad the influence of humanity on ecology can be and how important it is to act sustainably, because it shows the negative repercussions of a decision (to stop the dewatering of the mine) that took place over 200 years ago.
Thinking about the effects that those discharges might have in future, one has to take into consideration that at least the pH – level of water has changed from 3,3 pH (around 1800) to 6,1 pH (today) (Wilkinson 2011); an improvement can be recognized. Nonetheless, it is obvious that drainage water still has a great impact to organisms. It is necessary to think of methods to stop this pollution as it could lead to an extinction of organisms.
7. Analysis of the content
After talking about the project itself, it is now important to pay attention to the content itself. I therefore have selected some points that a worth having a closer look at. It is useful for a better understanding of the topic.
7.1 St. Monans and the abandoned coal mine
St. Monans is a village and is situated in the East Neuk of Fife. The village “has played an important role in the salt and coal industry for hundreds of years” (Angus 2002, 4).
With the beginning of industrialization, Sir John Anstruther and Robert Fall decided to establish the Newark Coal and Salt Company in 1771. One year later, in 1772, nine saltpans, a windmill, a

This milestone, which covers Section II of Final Project Part I, should be a paper structured as follows:
Around the world our water supply is depleting. Our water is becoming contaminated making it harmful for both mammals and aquatic life. Today over one billion people go without adequate water supply and every fifteen seconds a child dies of waterborne illness. Sources of water that once supplied water to millions can no longer meet the supply and demand of the water need. Scientist predict that the amount of useful water will keep depleting greatly in the years to come. In the next couple of pages it will talk about both the geological and human reasons as to why are water supply is depleting.
Chapter 5 described the outcome of the project. It concludes what is considered as an essence of every chapter and also what is the significance the project has delivered. Some recommendations for future works were also
In summation, I found this project to be very informative and very open ended. The key to success is getting an early start and taking the time to ask questions early so that there is enough time for the questions to be answered. The University of Phoenix provides us with the necessary resources to learn the required software well enough to succeed however, the best way to learn is to review the tutorials well ahead the project is due with no pressure to learn in order to immediately complete the assignment because the rush and the pressure will not allow for the best learning experience. The internet is also full of resources and knowledge that is of potential relevance to the class
In Mount Judea, Arkansas, there lies a hog farm very close to the historic Buffalo River, known for its natural beauty and amazing sightseeing. On the contrast, immense amounts of green algae have been found in its water in the past few years. As a result, suspicions have been expected with the possibility of the hog manure ponds leaking into the Buffalo River. This is an enormous environmental problem, as endangering a natural, free-flowing river is constrained in any aspect. The Big Creek Research and Extension Team (BCRET) from the University of Arkansas have recently drilled deep into these manure ponds in search of a leak and have accomplished their goal. (TFW). Around 120 feet below, there lies a wet place of soil that could possibility be the cause of green algae found in the nearby river. Individuals notice how big of a problem this can become. Three women, in fact, have appealed to constrain the amount of manure spread in the nearby fields surrounding the Buffalo River. (TFW). People love to see natural beauty, which is what the Buffalo River provides. Instead, they have to burden with the fact of green algae. Green algae can affect a body of water in many ways, including the contamination of turning these
When compared to the theoretical value, we had a 2.6% error in our experiment. Any errors that occurred maybe due to a too low intensity
I could like to improve on presenting this project because I feel like I am missing some important information. For example, I forgot to explains to the audience what are
Germination of seeds, and early stages of growth are important determinants in interspecies competition (Mangla et al. 2011). Higher proportions of B. gracilis seedlings to B.rapa will allow B. gracilis to gain an advantage both in germination, and in development of its roots and shoots. B. gracilis can then establish itself and sequester resources (water, sunlight soil nutrients) for growth and survival before B. rapa. Additionally, it was predicted that the mean biomass (root and shoot) of B. gracilis would increase as the ratio of B. gracilis to B. rapa increased. Multiple roots of long length in B. gracilis will be favoured as they can better compete in water and nutrient acquisition against B. rapa (Craine and Dybzinski 2013). Increased ability to acquire nutrients thereby increases the availability of nutrients B. gracillis has to grow, increasing shoot length and thickness. On this basis, the mean height of B. gracilis was predicted to increase as the ratio of B. gracilis to B. rapa increased as
As I calculate the sample means, the extremities are flattened out ,as we have a large sample size, and the average of these sample means lowers the spread of data inturn
Due to the errors that may have occurred the result may be invalid. There are two types of errors that were encountered: inherent and technical errors. Inherent errors included, the measurements of the slope of the ground, the accuracy of the pH, and wind speed. Whereas, technical errors included whether the pH colour card was clean (this could drastically effect the results, as residue of other pH can change the results), as well as the estimated canopy cover could have been inaccurate, as it was visually determined. Therefore, there are several factors that could have affected the result of the experiment. There are many ways, in which the investigation could have being improved to provide more reliable results. For instance, digital equipment’s
It is easy to imagine when Hardin (1968) wrote the Tragedy of the Commons; he anticipated things would get progressively worse over time, particularly if people did not respect the earth (Hardin, 1968). Although he did not mention any particular common, Hardin (1968) envisioned the world’s resources dwindling, as a result of people's mishandling of them. Hardin (1968) explained that “tragedy” in “The Tragedy of the Commons,” is the cruel way things work. It may have seemed as though things in the world were progressing without incident as far as resources were concerned, then, whether through culture or because of mere necessity, one day the tragedy of the commons occurs (Hardin, 1968, p.1244). This phenomenon is apparent in the movie
