VOICED: Pacific oyster farmers see global warming in poor harvest

The video discusses the challenges faced by the oyster industry due to the BP oil spill and climate change. It highlights the impact of ocean acidification on oyster larvae and the broader ecological consequences. The industry is adapting by monitoring water quality, but the rapid rate of change poses a significant threat to marine life and the food chain.

What event led to the increased demand for oysters from the Pacific Northwest?

• El Niño

• BP oil spill

• Overfishing in the Atlantic

• Hurricane Katrina

What percentage of oyster larvae died in the Pacific Northwest facility in 2009?

• 50%

• 25%

• 75%

• 100%

How does increased carbon dioxide in the atmosphere affect ocean chemistry?

• It raises the water temperature.

• It forms carbonic acid, making the water more acidic.

• It increases the salinity.

• It decreases the water's oxygen levels.

What adaptation measures are oyster hatcheries taking in response to ocean acidification?

• Using treated seawater

• Increasing water temperature

• Monitoring water quality and adjusting water sources

• Feeding oysters more frequently

Why is the current ocean acidification event unique compared to past events?

• It is caused by natural phenomena.

• It is occurring at a slower rate.

• It is happening at a much faster rate.

• It is affecting only shellfish.
