Claim: Without conservation planning, Lake Pontchartrain could change considerably because of human activities around the lake and upstream activities along the Mississippi River in the Lousiana eastern boundary.
Evidence: The lake could change considerably without such conservation planning. Hence, the ecosystems of the lake now, and in the future, depend very much upon some basic decisions about human activities in the vicinity of the lake, and, even more so, human activity upstream along the Mississippi River. A large part of its eastern boundary is demarcated by the Mississippi River.
