The 11th hour, is a documentary film produced by Hollywood superstar Leonardo Dicaprio. The film highlights how the human race, is causing sever ever-lasting damage to the earth by the constant need to develop economically. Dicaprio’s documentary invites over 50 experts from various academic fields, to give their opinions and possible solutions to the environmental issue at hand. The documentary implies that the human race is in danger from its own action, hinting that humanity could be extinct within the near future, due to Global warming, deforestation, depilation of oceans habitats, exhaustion of food resources, and the mass release of unnatural substances into nature. These environmental catastrophes originate from the belief that human kind is superior to nature and other living creatures.

To Vaccinate Cathy Albano Rasmussen College Author Note This paper is being submitted on July 12, 2014, for Dr. Laura Cleveland’s M232/MEA2203 Pathophysiology Summer Quarter 2014. To Vaccinate A battle against rabies in humans, in order to prevent this, animals must be vaccinated along with humans, over ninety-nine percent of all rabies infections in humans are from an animal bites. Rabies breaks down the immune system and spreads to the brain stem causing a dangerous affect which leads to death. It is imperative to have animals vaccinated to prevent them from getting the rabies virus, which in turn can be contracted to a human through a bite. It is estimated that nearly 55,000 human deaths occur from rabies, due to not being
Eugenics is the manipulation of genetics to improve the genetic composition of a population, usually referring to a human population. Eugenics has been around for a long time. When white settlers came to Australia the policy of removing mixed race aborigines came from a eugenics theory that full blooded aborigines were already dying out anyway because of diseases they caught from European settlers and that their population wouldn’t be able to sustain itself. However, in the last 50 years, there have been many new breakthroughs in biological eugenics. From the sequencing of the human genome, published in 2003 to the use of IVF for impregnation, we are only beginning to understand the lengths to which we can take this technology.
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
Lucy the Beginnings of Humankind is a novel about the impressive discovery of our ancestors by Donald Johanson and Maitland Edey. This discovery changed the way scientists thought about the origins of humankind. The discovery of Lucy proves that humans evolved from apes millions of years ago. It also provides further evidence that supports the fact that bipedalism preceded increase in brain size in human evolution. Finding 40% of the bones from Lucy was extremely impressive to scientists and especially to a paleoanthropologist because of the simple fact that these bones are over 3 million years old.
In the Article Faster Pussycat! Kill! Kill! Author Kiera Butler brings up a range of topics on this subject. The article discusses the dangers of domesticated and feral cats who are killing the US bird and mammal population and are currently responsible for 33 bird extinctions as well as spreading diseases such as rabies and toxoplasmosis.
The ultimate factors that explain why the Europeans first came to possess guns, germs, and steel are due to their head start in food production, and availability and use of domesticable animals (from which they derived many of the germs that would later wipe out the Native Americans). Basically, domesticated animals provided meat, milk products, fertilizer, land transport, leather, military assault vehicles, plow traction, and wool. The extinction of the megafauna 40,000 years ago “eliminated all the large wild animals that might otherwise have been candidates for domestication, and left native Australians and New Guineans with not a single native domestic animal.” Diamond includes this because after a few thousand years of eating big game, the megafauna went extinct leaving the tribes to resort to hunting-gathering. This fact set the tribes back even further because lack of domestic animals means lack of meat, milk products, fertilizer, etc. One of Diamond’s claims is that there were few animals, suitable for domestication, present in black Africa; since black Africans had little opportunity to utilize such animals, civilization was not in the cards for them.

BLUEPRINT OF LIFE 1. Evidence of evolution suggests that the mechanisms of inheritance, accompanied by selection, allow change over many generations outline the impact on the evolution of plants and animals of: * changes in physical conditions in the environment * changes in chemical conditions in the environment * competition for resources | Changes in physical conditions in the environment * These include natural conditions, such as temperature and the availability of water. * The Australia landmass has become drier over time and this has lead to changes in the species of kangaroos that are present today. Approximately 25 million years ago, Australia was considerably wetter than today with large areas of rainforest.
