Explain how climate change causes the ecosystem to become unstable. Include pollution in your answer. Include evidence from the article.
Lee Kantar lost two moose calves this past weekend. They were just a few of many calves that did not live past their first year in the forests of Maine. Kantar is a moose biologist for Maine's Department of Inland Fisheries and Wildlife. He has seen similar cases of moose dying young throughout northern U.S. and Canada. Scientists believe that the cause is climate change: As the climate warms up, diseases, brain worm, and winter ticks are becoming more common. In Maine, at least 50 percent of calves have died before their second year. In northeastern Minnesota, that number is as high as 90 percent. In the northwest of the state, the moose population has disappeared entirely. There are still signs of hope. The PLOS ONE science journal recently published a research article on how climate change affects vegetation in Alaska. The article explains that when temperatures rise and winters become shorter, vegetation will grow. In the tundra, moose have to feed on shrubs that poke above the snow. They will therefore follow it as it expands toward the warming northern territory. According to Kantar, this is a sign that the species will be able to live on.
