Wild Fund for Nature Director General James Leape also used the phrase around the same time. The most detailed examination of the environmental credit crunch and its interaction with the financial credit crunch occurs in “From Red to Green? How the financial credit crunch could bankrupt the environment” by Donovan and Hudson. This argues that the financial credit crunch will have both positive and negative consequences for the simultaneous environmental credit crunch. As a result, policy makers need to be more flexible in their responses to both credit problems. Another recent book that explores the topics without using the term "environmental credit crunch" specifically is, Richard Heinberg's "The End of Growth: Adapting to Our New Economic Reality". The book opens with a review of the financial crisis and the much discussed financial limits to future growth before addressing the corresponding environmental limits to growth.
