Human Dependence on Ocean Systems by KE and JC
Question | Answer |
---|---|
Wher does 80% of the pollution in ocean environments come from? | Human sources |
When there is a lot of precipitation for an extended duration, what happens? | Flooding |
What is an artificial reef? | A human-made underwater structure used as a habitat for marine organisms. |
What is one thing an artificial reef does? | Promotes marine life in areas with a generally featureless bottom, controls erosion, and discourages fishing |
If the climate rose by 1°C-2°C what would a major concern for humans be? | Sea levels might rise enough to flood coastal areas. |
How does fertilizer used in farming make its way to the ocean? | Stormwater run-off |
How does fertilizer in the ocean affect the ocean enviroment? | It creates algal blooms. |
What do algal blooms do to the environment? | Creates excess ammonia |
When humans build houses on wetland areas, they always do what? | Make changes that might not be reversable (e.g. habitat destruction) |
What does more CO2 in the air from cars, factories, and respiration mean for the ocean? | It means there will be more CO2 in the ocean, which forms Carbonic acid. |
Why is Carbonic acid bad for the ocean enviroment? | It means it will be harder for ocean organisms to absorb calcium into their shells and skeletons. |
How does ammonia affect ocean life? | Poisons and kills fish |
If a certain factory has a pipe that is dumping pollution into the ocean, is this point source or non-point source pollution, and why? | Point source, because we know exactly where it is coming from. |
If CO2 reaches the ocean and is turned into carbonic acid, is this point source, or non point source pollution, and why? | Non-point source, because we don't know who or where it came from. |
