hydroelectrically dammed

Q

What has the the answer to saving salmon during the past century been?

A

Produce salmon in hatcheries

23
Q

What is ocean acidification?

A

Ocean water absorbs 30-40% of CO2, CO2 & H20 bond to create Carbonic Acid, the release of hydrogen ions from Carbonic acid & bicarbonate molecules releases hydrogen ions which add acidity and affects pH of ocean

24
Q

How is biodiversity affected by increase in ocean acidity?

A
  1. Drops in metabolic rate
  2. drops in immune response
  3. increase parasites/bacteria
  4. destruction of coral
25
Q

What is Calcium Carbonate?

A

A molecule used by coral, mollusks and crabs to grow and repair their exoskeletons

26
Q

Why do some scientists believe overall cloud coverage will decrease, thus increasing the rate of global warming?

A

Phytoplankton populations will be reduced, thus they can’t create the chemical that contributes to the formation of clouds

27
Q

What is hypercapnia?

A

Excess of CO2 which can mess with immune response, affect odors used to identify friend or foe, affect echolocation
