Why were conditions made so tough for young Spartan boys at such a young age? Why was dying for Sparta considered an honor?-

Cthat is the answer

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.

This is a true statement  hope this : )
