Article: Ecosystems on the BrinkAuthor: By Carl Zimmer
Main Points:
Summary:
What humans are doing is causing the food web to flip. Instead of the highest level to stay the same since they have no predators they are decreasing causing the lower levels to increase rapidly. A group of ecologist made experiments in Peter Lake in Washington the experiment was to add bass to the lake. By adding bass to the lake small fish increased in population because a lot of their predators were gone. This showed that the food web flipped.
My Thoughts:
I think that the experiment that they did as a good idea because it helped them create a monitor that tells them when an ecosystem is being pushed to it's limit
So What? Says Who?
Scientist discovered that the food web will flip and they developed a monitor to detect when Carl Zimmer
environmment is pushed to it's limit
What If? What does this remind me of?
With monitors can we help prevent species from It reminds me of tragedy of the commons
extinction
Main Points:
- We are putting stress on the planet with farming and cities
- A scientist was able to create a mathematical equation that is able to predict change before it happens
- scientist have discovered that there more weak bonds in the food web than strong bonds
- we have done alot of unknown harms like fishing and adding invasive species to environments
- scientist discovered that when wolf population decrease elk population increase rapidly
- scientist thought that the recovery of cod would take 5-6 years but they were wrong
- fish called the forage fish ate the eggs of cod fish making the number of birth get lower
