GEOGRAPHY NOTES
· Since European settlement between 78 & 100 plant species have become are extinct. 150-200 under threat.
· GENETIC DIVERSITY - safeguard species diversity. Large range of genetic forms within each species. Genetic variations.
· Extinct- disappearance of species after thorough searching (some extinction is natural)
· At risk- in danger of becoming extinct
· Endangered- close to extinction in the wild unless something is done the species could disappear altogether
· Vulnerable- The step before endangered
· Rare- few of a particular species remain , less serious category than endangered
· Extinction can occur naturally because of climatic change which affects the vegetation on which animals depend.
· MEGAFAUNA-large Australian mammals from the ice age
· Aborigines 50000 yrs ago modified asia Australia bridge vegetation through burning it out resulting in dry arid landscapes. This also could have made extinct the megafauna.
· In Aus since 1788 only 30% of the vegetation remains unmodified to osme degree.
· Cultural Vegetation means exotic or introduced species, such as those found in ornamental gardens or pine plantations.
· The murray darling was dammed affecting surrounding habitats
· Introduced species have had a 3 fold effect on environments 1. Grazing
2. Competition between native and introduced species 3. introduced species can introduce formerly unknown diseases.
· In recent years large amounts of insecticide and weedicide have been used and effect the food chain
· Homozygosity- breeding of the same species of animals
· Hybridise- mixed breeding of plants
· Wildlife is harmed by recreation practises
· Oldest nat. park in Australia is Witches Falls in QLD founded 1908.
· Rachel Carson’s SILENT SPRING showed the impact that pesticides could have in areas far outside where they were applied.
· We are using up our renewable resources faster than we can replace them
· Unique plant and animal species
· Last remaining rainforest in Aus is between Townsville and Cooktown, it is on the world heritage list

After the fetus was found to be abnormal, the 2 partners were at discrepancy about whether to terminate the pregnancy or not. Gwen wanted to terminate the pregnancy while Nicole insisted on continuing the pregnancy. This dispute put stress on both partners and caused the first tear of their relationship. Besides the couple, everyone in the care team is also facing this ethical dilemma. Some people might agree with Gwen while others might be on the same page with Nicole. Some people might have no side but feel troubled and distraught by the situation. It’s natural and normal for care providers who are involved in a situation like this to have an opinion based on their personal
In August 1945, the United States dropped nuclear bombs on Hiroshima and Nagasaki. When she began writing Silent Spring in the 1950s, Carson was acutely aware of the short and long term impacts of these events (Carson, 1962). As a naturalist and scientists, she worried about the long term effects of nuclear fallout and the misuse of pesticides. Her work for the U.S. Department of Fisheries gave her unique insight into the rapid ecological system changes due to pesticide use and our own culpability in creating the insect and pest problem to begin with (Biography, 2011).
Native plants in any given area have adapted to all the other organisms in a given area and genetically diverse ecosystems are generally maintained.
This dense and luxuriant rainforest has the greatest diversity than any other in Australia and many in the world. The Daintree is also the home of rare and threatened extinct plant and animal species. The importance of this ecosystem is the very high. This ecosystem contributes to the overall health of this plant in many ways. Diversity contributes to the breakdown of pollution and helps to control the climate to name a few.
Rachel Carson’s Silent Spring revolutionized the American point of view concerning the environment. It rejected the notion that pesticides and chemicals are the right choice for “controlling” various animals that are seen as an inconvenience. Carson writes about the dangers of pesticides, not only to nature but man himself.
Furthermore, Tony Harrison’s V explores the relationship between centres and margins through language. Harrison uses language in order to not only give voice to the working class, but also to challenge dominant ideologies and dominant voices which are bound up with the use of Standard English. Previously discussed in reference to The Lonely Londoners, Standard English is associated with power and elitism and thus ‘places as subordinate all the utterances that are literally or figuratively between inverted commas’ (). This is challenged in V. in which the privileged voice of the eloquent bourgeois poet () and the working class ‘skinhead’ argue. Harrison was concerned with issues of articulation and voice, this is clear throughout his poetry and he discusses this in an interview: ‘And that the idea of articulation, expression, became for me absolutely vital
Technology continues to progress. Today, every business, school and organization thrive mostly because of a well-developed website or an application that is easily downloaded into any mobile device. Healthcare, as well has been progressively adding ways to incorporate the use of electronic devices. The use of the patient’s portal and the electronic health record are only a few technological advances in healthcare today. A bedside nurse working in an acute care has the competence with numerous gadgets operated to ease the patient care process.
On the first level, when foreign, but previously non-invasive species is first introduced to a new area, the new species may play a role in a community that was previously unfulfilled; it may fill a vacant niche in the ecosystem. Originally this new species may be seen as a useful contributor to its new surroundings because it has only (temporarily) increased biodiversity in the area (Meinesz, 2003).
That is, the conservation of selected plants and animals in se¬lected areas outside their natural habitat is known as ex-situ con¬servation. The stresses on living organisms due to competition for food, water, space etc. can be avoided by ex-situ conservation there by providing conditions necessary for a secure life and breeding. Such strategies include establishment of botanical gardens, zoos, conservation strands and gene, pollen seed, seedling, tissue culture and DNA
On the other hand, with the benefits of technology in improving health, it has been a daunting task for the healthcare workers to adapt to the ever-changing technology. In addition, the cost of Health IT system much especially for the private provider is expensive because of the purchasing cost of the IT components and maintenance, technical installation, licensing fees and opportunity cost of learning duration for the healthcare providers. For this reason, the rates of exploiting the benefits of technology in healthcare delivery are minimal as compared to that in the administrative and financial sector within the Health industry. This has had a surprising turnout since the high cost of investment in Healthcare technology is met with a low rate of its use to improve
Assessment methods can be described as being either Formative or Summative. Formative assessment is utilised as a method of continuous monitor through incorporating it into daily teaching practice and is fundamental the teacher’s responsibility to implement. This type of assessment therefore provides the perfect opportunity for teachers and learners to discuss the learning which took place and be able to identify areas of teaching/learning strategies that could require amendments. Summative assessment can be employed both internally and externally. Internal summative assessment could be in the form of an end of topic test and used to record individuals’ progress that can be shared with pupils, parents and other teachers. External bodies such as the Scottish Qualifications Authority (SQA) produce summative assessment in the form of exams in order to award individuals with a specific grade for certain subjects. These methods are continually used in schools and if used appropriately by teachers, do have a positive effect on the learners. It is the responsibility of the teacher to gather information from these assessments to not only evaluate learning, but also evaluate their own personal teaching practice. Effective and appropriate assessment can encourage pupils to focus their learning and help provide them with achievable but challenging goals. Communicating with pupils and setting goals will increase their motivation and enthusiasm for learning through providing them with a clearer understanding of what is expected of them in order to achieve their goals. Through using continuous assessment it supports the detection of where learners need assistance and allows teachers to guide and provide additional materials where necessary.
I remember when I first thought about the power one person could have to create change. I was a teenager growing up in the South when I read Rachel Carson’s book “Silent Spring”. This beautifully written book is a powerful indictment of the widespread use of pesticides. Rachel Carson criticized the chemical companies for claiming that pesticides were safe despite mounting evidence to the contrary. And she criticized public officials who accepted the chemical industry’s claims.
I would like to bring to your attention the benefits that will accrue due to technology adoption in our health sector. Firstly, it is the improvement of the patient care. This is in regards to the efficiency and optimal in the patient care delivery. There is a need for the technical implementation of how to enhance nurses' communication with the patients, physicians, and other nurses. In case of emergency, medical personnel can easily communicate without risk of losing information due to wreckage or poor handwriting. It is also important to note that technology can automate the less value-adding elements of the patient experience enhancing customer satisfaction and service delivery (Sultan,
In our world today we have approximately 26,021 endangered species. Endangered species are organisms that may possible become extinct. The term 'endangered species' refers to all species that fits this description. However some conservation biologists and scientists normally use the term ‘endangered species’ to refer to species that are put on the IUCN(International Union for Conservation of Nature)Red List. Many factors can be looked at when considering the conservation status of a species. Factors such as human threats or environmental threats can cause a species to become endangered.
