The Black Death swept across Asia and Europe during the middle 1300’s. It began in Central Asia. Ships that were used for trading carried rats. When the people got bitten by the fleas on the rats, the fleas gave them the plague. From these ships, the plague spread throughout Europe.
The Impact of the Industrial Revolution on Our Environment The Industrial Revolution had a large, negative impact on the environment. Before the Industrial Revolution most peppered moths in Britain were white, however, the amount of coal and pollutants produced during the Revolution changed the color of the moths' environment. Soon, the darker moths were more well camouflaged, and the white moths all but died out. Peppered moths were not the only creatures impacted by the Industrial Revolution, humans and domesticated animals were also effected. “Industrial Britain was hit by an outbreak of cholera in 1831-32, 1848-49, 1854 and 1867.” ("Diseases in industrial cities in the Industrial Revolution" 1).
Rodents played a large roll in spreading Bubonic plague. Plague occurs in arias with a lot of burrowing rodents. During the renaissance rats were probably big problems. Any rat living in someone’s home or running down the street could be infected. Rodents also act as long term preservers for plague.
The disease spread like any other thing, it traveled through trade. The plague comes from fleas on rats that carries the disease. The rats first made their way to Europe on boats form China and the plague slowly moved more inland. In 1347 intailin traders brought to plague to Sicily and spred it to Milan and flouence it also made its wayt o middle eastern countries. It makes it way throughout Italy and by 1348 it has hit
Running head: Plastic Oceans 1 Plastic Oceans Ben Smith Oakland University PLASTIC OCEANS 2 Abstract The amount of plastic debris is a growing trend that is becoming increasingly more dangerous by the day. This plastic pollutes and kills innocent animals, and is and at the same time is broken down into tiny inconceivable amounts by photodegradation that are almost impossible to collect. 80% of this plastic comes from land, a source that we most likely can control, with the exception of weather and natural disasters. The Great Pacific Garbage Patch is proof that plastic pollution is a growing epidemic and the ocean just continues to resurface the same plastic because of the currents in the gyres. This process begins polluting the ecosystem and harming the food chain from the toxins plastic absorbs and releases.
Experiments conducted by Calhoun (1962) involved the overcrowding of rat populations which gave rise to killing, assault and cannibalism. Overcrowding can increase negative effects such as irritation, discomfort and frustration brought about by the feeling that personal space is being invaded. However this feeling of invasiveness varies between cultures – what is considered unacceptable in western culture is not necessarily true
Oceans are being polluted by substances such as farm fertilizers, chemicals produced in factories, and harmful sewage from towns and cities (Claybourne 38). Trash and debris, especially plastics, are deposited into the oceans by humans. These objects can be mistaken as food by many species, which eventually leads to death. When species consume what looks like to be food, but in reality is hazardous waste, the animal contains that chemical inside of them. When a larger animal consumes the hazardous animal, it affects the entire food chain (“What Is Ocean”).
Drowning in Plastic It’s hard to imagine life without plastic. It’s everywhere: covering our food, holding our purchases, protecting our loved ones, saving patients in hospitals and floating along our waterways and oceans. The thought of living in a world surrounded by toxic chemicals and pollution is a thought which many would rather not think about. Plastics have revolutionised the world in which we live, but with dire consequences. The production of these toxic-filled substances continues to lead the human race on a path of natural destruction; with thousands of animal sea-life dying annually from plastic consumption.
The sea animal cannot adjust to these changes in the ocean due to global warming. Pollution is another big problem that is threatening our ocean. The ocean has become a dumping ground. These toxins are affecting the ocean in a harmful way. This is also hurting sea life.
The ocean dwellers are virtually helpless, and they will ultimately have to suffer the consequences that have been created mainly by humans. Over the past few years there has been a significant change in marine life. Coral reefs are becoming endangered due to high carbon dioxide levels and effects of warming. Large predators, small fish, and other organisms make their homes in coral reefs. A process called mass bleaching has also become a danger to coral reefs.
