150 words writing of threats to sharks

the threat I choose is (climate change)

In this discussion board, you will research and reflect on threats to sharks. Please respond to the following prompts: 

1. Threat summary:

• Pick one (1) threat to sharks from the list below, and describe that threat:
  • Bycatch
  • Shark finning
  • Overfishing
  • Shark nets (to reduce shark attacks)
  • Climate change
• Add a short title of what threat you have chosen at the beginning of your summary (e.g., 'Bycatch:'). 
• Your summary should be approximately 150 words and should include:
  • Numbers that quantify the threat to the extent you can find (e.g., number of sharks killed by bycatch annually)
  • Links or citations for your information
• In picking your threat, be sure to look at what your group mates have posted, and there may only be two summaries of the same threat within a group.  In other words, if there is one post about bycatch, you may also do a summary of that threat; if there are already two posts, you must do a summary of a different threat.
• Include a photo or video !
