Case Study: Can Polar Bears And People Coexist?
Task 1
Can polar bears and people coexist?
Polar bears are the largest land predator on earth today. They live in the Arctic area, surrounded by the northern nations like Norway, Greenland and Canada. The effects of global warming have caused the temperatures to rise, which have led the Arctic ice to melt. Because the polar bears’ territory is shrinking, they are forced to hunt further inland. They usually hunt on the sea ice, but they cannot do that now. A polar bear can starve for months, but they will get even more desperate for food as the time goes. So they are in a state where they are willing to do everything for food, and we do not want to be in the middle of them and another animal. Imagine going for a walk, and then suddenly spot …show more content…
Climate change is one of the biggest challenges we are facing in the world today. It cannot be ignored, and if we want to create a sustainable future for the next generations, we must act. Some says that climate change is not caused by human activities, and some says that it is. In this essay, I will discuss the results of climate change, how it is affecting our world and whether or not climate change is caused by humans
When talking about this subject, it is important to know what global warming is. There is something called the natural greenhouse effect, and the human enhanced greenhouse effect. If it was not for the sun, we would not have been able to exist. We get solar radiation from the sun. It goes through the atmosphere and warm up our planet, and then the re-radiated heat escapes into space. If the re-radiated heat cannot escape, it will get warmer than it is naturally supposed to. This is happening right now. The rise in temperatures have cause a lot of damage to our planet. This would also lead to more greenhouse gases, especially CO2 and CH4, floating in our …show more content…
Most scientists claims that global warming is caused by human activities, but there are people who simply deny the existence of global warming. I cannot understand how someone can say that climate change is not caused by humans, the effects are undeniable. Big meteorological corporations have done research that proves that the average yearly temperature have increased over the last 20-30 years. This summer there was a heatwave in central Europe, and the temperatures in Paris was over 30 degrees. In central Germany the temperatures was up to 40 degrees. This is not normal. It will probably become even warmer in the next years.
The sea levels are rising, the glaciers are melting, the people in china are wearing masks not to be poisoned or sick by all the pollution in the air, it has become more extreme weather. The people who believes that climate change is not caused by humans, says that the climate have been known to change over time and that we should just look at the current situation as a part of the planet’s natural circle. These people do not even have any scientific proof to backup their claims. The speed of these changes in our climate are too high for there to be another reason for it, except human
