Polar bears were the biggest and most feared predator in the North Atlantic, until recently. This paper will explain what is happening to the polar bears due to the melting ice caps, what the result of this is and how that is going to change the entire region. It will focus on primarily three factors; climate change and CO2 production, the invasion of killer whales (Orcinus Orca), and how the invasion into the north will effect human civilizations. Introduction The world’s climate is changing rapidly. Humans are pumping more carbon dioxide (CO2) into the atmosphere than any time in history.
Since the Industrial Age and the Industrial Revolution until now, we have poured endless amounts of smoke, trash … into the air. That much toxic waste has now accumulated enough to change the entire world, forcing it to readjust. This not only affects us, but millions of other species as well, threatening life as we know it to end. Effects of climate change You might think that the weather changing is just a normal thing, but climate change is much worst. Animal to this day have adapted to its surroundings; for example, tropical birds have evolved to live in tropical forests.
Mining the hydrothermal vents could make it so that some very bad things could happen to our earth. Mining is very bad idea until we finish all of the studies about hydrothermal vents because very bad things could happen to fish and the communities nearby the mining. First, The vents are used as homes for species. Mining could wipe out all of the yet to be discovered species. Mining will pollute the water and let out toxins that can kill species and communities near by.
Wolves should be kept on the endangered species list because as seen through evidence they help the environment in many ways that people don’t always see. Imagine a world where wolves don’t keep the deer numbers in check or kill off diseased/injured animals, the whole ecosystems of some areas would be completely ruined. Other animal species would die out if wolves are their main predator because they would begin to over populate which would leave them to over using their food supplies and then starving to death. Animals would have to be forced onto the endangered species list costing us tons of money only for it not to really help. It would be sort of like a chain reaction if wolves were to be taken of the list and then go extinct, and we never know if that chain reaction would affect us very badly or if it not affect us at all until it is to
The earth was covered with extensive polar and mountainous sheets of ice. So much water was taken up with ice that the global sea level dropped almost 140 meters. This time in earth’s history would be considered a glacial period. Oceanic circulation, solar energy fluctuations, continental positions and earth 's orbital cycle caused these conditions. Glacial global temperature changes between the ice ages and interglacial periods were due to the concentration of greenhouse gases.
As polar bear population decline so does the population of seals which is a fatal cycle for polar bears, because without ringed or bearded seals, polar bears cannot survive and will be pushed inland. The fallout from the bears being pushed onto the mainland could be detrimental to the Inuit population that are in coastal regions of the ice caps, as bears have been reported to be increasingly more aggressive with humans, it is only a matter of time before the interactions become fatal. Now, not only do they have to adapt to warmer weather, but they also have to deal with the diminishing of the land that they inhabit. Polar bears run the risk of becoming extinct, because without the large ice surfaces, they will have no place to live. It is largely believed that polar bears have adapted to new conditions once, and would have no problem doing so again, however this is utterly incorrect.
Describe how human impacts are causing many species to become endangered or go extinct. Humans do a lot of bad things, that cause many species to go extinct or become endangered. One of the biggest problems is human predation. Humans do a lot of harm by hunting. They erased the megafauna mammals of the last Ice Age, decreased the population of whales and other marine mammals, and wiped out the Dodo Bird and the Passenger Pigeon.
Not only sea animals, but animals all over the world might extinct or become endangered because of pollution. If our future generation has less food, people from all over the world will suffer from starvation. They will not only suffer from the lack of food, but also from the disease that pollution causes. Our world will become something so frightening and unsuitable for any living
Global climate change constitutes arguably the single most important threat to mankind. From the onset of the industrial revolution, greenhouse gas emissions (GHGs), including carbon dioxide (CO2) have increasingly built up in the atmosphere, causing the climate to warm up slowly but steadily (IPCC, 2014). NASA predicts that 2016 will mark the hottest year on record. The effects of global warming are ubiquitous: Greenland’s glacier and the Arctic ice cap are melting, ocean levels are rising, occurrences of extreme weather are increasing, including hurricanes and areas of either intense drought or flooding. Collectively, these changes and their direct consequences are an imminent danger and they directly affect other urgent issues humanity is
But it is just stereotype that we have to protect all the animals when they are in danger. Website The DEBATE.org states that "Everything will eventually starve to death if we allow everything to live. Then w 'ere REALLY monsters as humans. Look at Yellowstone. There are many examples of the negative consequences of over protection - we almost made certain trees extinct when we protected them from fire.
