It’s the world D
The reasoning is because when u search up Africa the Arabic comes up so yeah
Answer:
Human interaction with the ecosystem has rapidly spread disease to Yellowstone's wildlife, which has proven to have adverse effects on populations. Also, humans tend to leave trash in poor areas. Littering is a problem in Yellowstone because it can be ingested by the wildlife and also pollute the park...
hope it helped you :)
Answer:
animal wastes and fertilizers
Explanation:
The majority of the nitrates that are polluting the rivers come from the animal wastes and from the fertilizers used in the agriculture. The increased amounts of nitrates in the rivers causes eutrophication. This basically means that the water is becoming over-saturated with nutrients. This leads to the spreading out of the algae. As the algae spread out more and more, they cover the surface part of the water, so large portions of the rivers do not receive sunlight, which kills of the organisms that use photosynthesis. Further, the algae reduce the amount of oxygen in the water, often resulting in dying out of the fishes. It is a chain reaction that leads from one thing to another and the end result is devastating.
Answer:
They have reduced the river's force to almost nothing by the time it finally empties into the sea.
Explanation:
The Colorado River is one of the biggest rivers in North America. It runs mostly through the United States and little through Mexico where it ends its flow and empties into the sea. This river has been the subject of heavy exploitation by humans, and for that purpose, numerous dams have been built on it.
The number of dams is so high and the water is used at such a high rate that the river barely has any water as it empties into the sea. As this river runs mostly through arid and semi-arid areas that are also used for agriculture, its waters are heavily used for irrigation, leaving less and less water in the river as it gets closer to its endpoint. The dams are helping a lot in the economies of the states through which the Colorado River runs but the effect on the ecosystem of the river has been devastating.
