Patrick Moore, Ph.D. in Ecology, founding member of Greenpeace, who turned realist. "I love nature and people are part of nature - all people and all living things. I believe in one human family. Environmentalism must be beyond nationalism, politics and ideology." Many papers on ocean acidification, said to be caused by rising man-made CO₂ levels in the atmosphere, predict it will result in mass extinction of marine species that employ calcification and in turn will result in the extinction of many other marine species. There is no evidence to support the claim that most calcifying marine species will become extinct owing to higher levels of CO₂ in the atmosphere and lower pH in the oceans.
