The arctic has been a section of the world with the clearest negative impact of the effects of climate change. The ice caps are slowly melting, while there are different species of life being threatened through the diminishing food source in this densely populated area. The melting of the ice effects the environment in so many negative ways like releasing trapped bacteria in the ice, eliminating food source that can’t adapt, and creating an unstable life cycle. There are different species of assemblages that have adapted to the living conditions of both above and under the ice, representing 20% of the main algae source of food in the Arctic. The melting caps are causing these limited resource available to the birds, fish, and marine mammals causing many of these animals population to diminish because of the lack of algae. The polar bear is one of the most effected as they really on the smaller food source around that really on algae. The interruption to the life cycle in the Arctic was caused by humans and these animals are suffering without having any major cause in the event. The table shows the decline sea ice in the Arctic Ocean measured annually starting from the 80s to the 10. This correlates to the global warming of the planet, causing global change and the arctic is being impacted in rapid rate.
This graph provides great insight into the depletion of sea ice. This significant decrease, shown on the graph, in sea ice in the Arctic Ocean is very scary as it leads to less available resources for wildlife and marine animals.
This is an especially interesting phenomena because of the unique chemical structure of H2O in that liquid water contracts whereas solid ice expands and traps air with in it which creates a different level of buoyancy. I think you did a good job touching on the wildlife that will be effected as a result of rising temperatures.
This is an unfortunate reality of the increased human population on earth. All around the world, countries are industrializing and moving themselves into the 21st century. While technological advances in medicine, science, and convenience represent positive strides for societies, they come at an overlooked cost. You do a great job speaking to the loss of animal life that occurs in places like the Arctic as a result of melting ice caps.
It’s too often the case that as one benefits and advances, another loses and retreats. This is seen again in the case of marine wildlife in the Arctic as you present and discuss. Unfortunately, without significant steps taken to address these issues and developments, they will continue, and the effects on wildlife will only get worse.
