The movement of a river typically begins to decline as it approaches its mouth, where it meets a larger body of water, such as an ocean or a lake. In this area, the gradient decreases, leading to slower flow rates due to reduced elevation and increased sediment deposition. Additionally, factors such as human activities, damming, and water extraction can also contribute to the reduction in river flow over time.
Populism is not in decline. See the Tea Party movement, and Sarah Palin.

The human body begins to decline at an old age or it can decline due to the lack of nutrition.
Factories begin because of the working conditions.
If the numbers of a species begin to decline dramatically, the species becomes known as an "endangered" species. When the numbers decline so far that the species no longer exists, the species is known to be "extinct."

If fish in a river begin to die due to pollution, the entire river ecosystem may face significant disruption. Fish are crucial for maintaining the balance of the food web, and their decline can lead to an overpopulation of other organisms, such as algae, which can further degrade water quality. Additionally, other species that rely on fish for food, such as birds and mammals, may also decline, leading to a cascading effect that destabilizes the ecosystem. Overall, the loss of fish can result in decreased biodiversity and compromised ecological health.
