Habitat for mantaees

A Manatee inhabits many areas such as rivers, canals and even coastal areas. However with recent climate changes this may be subject to change in the long run. Some predictions that I have is that Less water can be found on earth which results in loss of habitat for the manatees. In addition when the temperature decreases the manatee mortality rate increases since they can lose body heat. Therefore the habitat of a manatee might be filled with algae.
