H. Leighton Steward is a geologist, environmentalist, author, and retired energy industry executive. He has written about the reasons for the loss of much of the Mississippi River delta (Louisiana’s National Treasure) and has given advice on how the nation can achieve “no net loss” of wetlands in the future; advice that has been accepted by the EPA and U. S. Corps of Engineers. Leighton was lead author on a book about nutrition and health (Sugar Busters) that gave advice on how to lose weight and prevent and or treat diabetes. The book became a #1 New York Times Best seller for sixteen weeks and made a significant contribution to the changes that have occurred regarding the availability of no-sugar-added, higher fiber, and low-glycemic products in the super markets. More recently, he has written a book Fire, Ice and Paradise that is an endeavor to educate the non-scientist about the many causes of global climate change so that the reader will be better prepared to understand what they hear, see, and read about in the media and from the politicians. In recognition of his many environmental efforts, Leighton has received numerous environmental awards, including the regional EPA Administrator’s Award for environmental excellence.
He is Chairman of the Board of The Institute for the Study of Earth and Man at SMU, was Chairman of the National Wetlands Coalition, and was twice Chairman of the Audubon Nature Institute. Leighton currently serves on the boards or boards of visitors of the M. D. Anderson Cancer Center, EOG Resources, The Buffalo Bill Historical Center, the Southwest Research Institute, and is an emeritus member of the Tulane University board.
Leighton’s current interest lies in helping to educate the general public and the politicians about the tremendous benefits of carbon dioxide (CO2) as it relates to the plant and animal kingdoms and their related ecosystems and habitats, and the general health of humanity.
