The human's impacts to Murray-Darling river are wastes the water, throw rubbishes and pour the toxic waste. The most human's impact to river is pouring toxic into river. Because toxic waste is poisonous, so if someone in a factory pours toxic waste into the river, the poison will spread into the river. So the poison water flows into ocean. But while the water flows into the ocean, the fishes drink the poison water also the water flows into the ground and the ground grows poison plants

Into the ocean, on the side of the road, (burying it) in the ground... It's a horror. Not one major river or ocean on the planet remains untainted by human waste and/or pollution.
The Chesapeake bay is in danger because people are throwing waste into the water and, people are also pouring cow manure, human sewage, and fertilizer in the bay and causing Algae blooms which blocks the sunlight for the animals and the bay grasses.
The river becomes 'polluted'.
