Greenpeace has linked the spread of the parasitic beetles, which are responsible for the destruction of millions of hectares of forests in southwestern Alaska, to global warming. According to the National Wildlife Federation, climate change will enable 48 percent of invasive plants and animals in the United States to move further north as temperatures rise. (Photo: Reuters)
