how much area has the everglades lost in the past year?

In recent years, 50 percent of the original Everglades has been lost to agriculture and urban development. This equates to about two million acres. Much of the area is now protected as a national park.

When a lake, river or other aquatic  system  becomes  eutrophic, it can have serious negative effects on other organisms like fish, birds and even people.if an algal bloom is so bad that it causes wide-spread death  in  the  water, the organisms that die will all sink to the bottom and start to decompose.
