The topic is ‘How does damming the Colorado River affect the Grand Canyon?’;

The multiple dams surrounding the Grand Canyon have held the Colorado River like a closely monitored aquarium. The canyon has had to adjust to these obstructions for many years. For example, there has been increased algae growth, a change in fish population, and all the vegetation has caused the return of beavers. Insects, birds, and reptiles have all been affected due to the changes in the river’s content, temperature, and flow. Leisure or recreational use of the Canyon is different as well. Thousands of people who raft down the river each year now have difficulty making it through the rapids because of debris floating in the water. River beaches wash away due to the trapping of soil and rock behind the dam. The Colorado River has been transformed into some sort of plumbing system and scientists are hard at work trying to do something about this catastrophe.

Help?!

I would add more detail, such as what kinds of algae? What percent growth? Is that killing fish? Which ones? how exactly have the birds, insects, fish been affected? What exact changes are there in the temperature? How much has the temp risen? What kind of debris is in the river? What are conservationists doing to help solve the problem?
