Many of the aquatic invertebrates are responsible for keeping the ecosystem clean by feeding on litters. Extinction of theses invertebrates would totally disrupt the balance of the ecosystem. The aim of this study is to bring awareness about the harmful impact global warming has on the local aquatic invertebrates and on the ecosystem at a global scale. The hypothesis for this study is that the biotic diversity of the slow moving water and fast moving water are driven by abiotic factors. To support this hypothesis, three predictions were made.
These scientists play a very important role in developing new ways to protect the seal population. In relation to this article Duke University faculty and the International Fund for Animal Welfare were major stake holders in publishing the study. The issue of the decline in harp seal population is global, economic and biological. The warming of the oceans’ waters is a problem that humans and wildlife are facing all over the world. It is also a problem that does not have many possible solutions, causing it to be the most detrimental to harp seals.
This falls to the side of letting natural selection run its course. Whenever the author talks about the opposing side, he quickly counteracts with why that wouldn’t work. He also strongly mentions how human interaction is one of the key points in why we have this problem in the first place. Unanswered Questions: In what ways are the barred owls taking over? The spotted owls are threatened due to loss of habitat, and the habitat that they have is being taken over by barred owls.
Explain why the impacts of global warming are predicted to be uneven and unfair. Evidence of the impacts of global warming is accumulate and becoming more precise. Its effects on people, particularly the poor minorities, indigenous peoples and others living in low-lying areas and other vulnerable regions, are becoming more apparent. The most prominent characteristic of global warming is the inequality in which the human population would experience it. Global warming is a result of greenhouse gas emissions being let off into the atmosphere.
Scientists were studying this correlation and discovered some of the reasons for this higher mortality rate. Some otters are caught and killed in fishermen’s nets, some drown in lobster pots, and predators such as sharks kill some. A final explanation for their low population in California is infectious diseases, which mostly kills
With reference to one or more located examples, describe and explain the different impacts of flooding (25 marks) Floods can have a major impact on the environment and society. The impacts can be social, economic, and/or environmental. Although the vast majority of the social and economic impacts are negative because they result in costly repairs and the disruption of peoples’ everyday lives,, some of the environmental impacts can be positive. For example, floods spread sediment containing nutrients over soil that may not have reached had there been no flood. Whether or not a country can cope with the effects of a flood depends greatly on whether it is a less economically developed country (LEDC) or a more economically developed country (MEDC).
My first piece of evidence in favour of human activity leading to extinction is ‘humans are driving animals to extinction faster than they can evolve ‘written by Juliette Jowit, (on Sunday the 7th of March 2010), the guardian newspaper, 15/01/15. This source is very reliable as it has been said by experts on animal, survival and extinction. In this article it explains that humans are one of the main causes of animal extinction and this is driven by the destruction of habitats(deforestation),hunting, the spread of alien predators(invasive species),disease and climate change. Also, due to these causes humans are effecting the cycle of evolution and this partly happens through the
To be as successful as possible it was in the best interest to be an Empire. With the rise of empires comes a social change. This includes mix of cultures, belief and dominance. Biological exchange includes the exchange of disease, food, animals and people. The New World’s isolation from the rest of the world effected peoples of the Americas immunities being weaker than the rest of the world.
Environmentally, whaling has caused the endangerment of certain species of whales. The main environmental concern of whaling is that it would harm the balance of the ecosystem through the extinction
The biology of dolphins and whales changes in marine park conditions. Their diets are different, they have significantly shorter lives and they are more likely to suffer from disease. Furthermore, mammals in marine parks are trained and this means that their patterns of social behavior are also changed. Consequently, research undertaken at marine parks is generally not reliable. For instance, the research into the behavior of killer whales that was conducted by
