(1)What is overfishing
_____________________________________________________________
__________________________________________________________________
___________________________________________________________________
______________________.
Overfishing is closely tied to bycatch—the capture of unwanted sea life
while fishing for a different species. This, too, is a serious marine threat that
causes the needless loss of billions of fish, along with hundreds of thousands of
sea turtles and cetaceans
After-class

The damage done by overfishing goes beyond the marine environment.
Billions of people rely on fish for protein, and fishing is the principal livelihood
for millions of people around the world.
(2)What did we learn from the Deepwater Horizon disaster

The Deepwater Horizon blowout caused gas and oil to spill into the Gulf of
Mexico for 87 days. Years after this environmental disaster, scientists studying
the spill better understand the complex processes that affect how oil transforms
and degrades in the water and just how resilient ecosystems can be to such a
disturbance. The disaster response also did nothing to clear up debates about
chemicals called dispersants that are often used in spill cleanups. Researchers
hope that the technological advances over the past decade—and the knowledge
gained—will better prepare the world for the next big spill.
Thank you!
