Despite the common goal of environmental protection, federal agencies lately stand divided over the best use of our natural resources – to protect wildlife habitats or to expand water resource development for the future. More and more, these issues are splintering the industry into two camps supportive of either the Clean Water Act or the Endangered Species Act.
