Warming streams could be the end for salmon

Summary:

            Warming streams in California could be the end for Spring-run Chinook Salmon by the end of the century, say scientists at UC Davis, the Stockholm Environment Institute and the National Center for Atmospheric Research.

     In almost all scenarios, the fish died out because streams became too warm for the adults to survive the summer to spawn in the fall. The only thing that could preserve salmon populations for a few decades was to reduce the amount of diversions for hydropower generation at the warmest time of the year. Hydropower is often part of renewable energy portfolios designed to reduce greenhouse gas emissions.

Critique:

            Scientists should figure out more of what to do to save all of these salmon in the streams. They could possibly move them from one stream to another once one is too hot or cold for them to be in. they could also control the temperatures in the stream to make them cool when they are hot.

Impact:

            The impact of all of the salmon dying would be a big impact on food. If all of the salmon died in contaminated water we would no longer be able to eat the salmon. Salmon is a very popular fish to eat, and if not available that would be a big disappointment to many people.
