Question

Carbon dioxide emissions are contributing to climate change, which is causing average global temperatures to increase. These temperature increases have led to a loss of sea ice in the Arctic. Populations of polar bears, which depend on sea ice as part of their habitat, have declined as a result of this loss. The rate of Arctic sea ice loss is predicted to increase if the current temperature trends continue.

What is the best long-term solution to help maintain polar bear populations?

A.
replacing fossil fuels with renewable energy sources
B.
establishing several protected regions in the Arctic
C.
introducing plants capable of bioremediation to the Arctic
D.
identifying new sources of fossil fuels around the world

Answer 1

@velmalovesshaggy145 : The best long-term solution to help maintain polar bear populations is to replace fossil fuels with renewable energy sources. This will help reduce the carbon footprint and slow down or stop the trend of rising global temperatures that are causing the loss of Arctic sea ice. Establishing protected regions in the Arctic can help protect the current polar bear populations, but it will not address the root cause of the problem. Introducing plants capable of bioremediation to the Arctic is not relevant to this issue. Identifying new sources of fossil fuels around the world will further exacerbate the problem. Therefore, option A is the best solution to help maintain polar bear populations in the long term.
