In this book it talks about Dead Zones.A Dead Zone is a place with little to no oxygen.Because of this the book explains that animals that live at the bottom of Dead Zones will die.The fish in the area will have to move out as well.This forces fishers to go miles out into the water just to get one fish.The Gulf of Mexico has the biggest Dead Zone.A Dead Zone can happen when algae form at the top of lakes and take all the oxygen leaving none for everything else.This has caused fish population to go down exponentially.

I think this is a good book.It tells about a problem that will affect our generation.It gives bulleted information sites it's sources.The sources are especially good because it tells someone didn't pull this out of thin air.It is a problem that people need to take action on.This book lists all the reasons why this is a danger.It is also a danger to our food supply and food is something humans need to live.This is why it deserves a 5 star rating.It is a problem that needs action now.
