Because just like us they are living, breathing animals. That's like saying why sould we try to keep humans alive. Just like the manatee we can't go extinct. Because then their would be none of us left. That's why we need to keep manatees alive.. ? ;)
The Florida Manatee population is 4000-5000 in 2011.
it is need to keep a plant alive
They don't. Manatees are herbivores, plant eaters, and you rarely need to hunt for plants.
animals need water to keep them hydrated, healthy and alive.
manatees are fat so they can keep warm
Food and water.
Actually any thing can fart aslong as it is alive ,but manatees fart when the are dieing.
They don't have one. Manatees are herbivores, plant eaters, and you rarely need to hunt for plants.
Yes indeed they are. Plants provide manatees with the nourishment that they need. The plants make the manatee strong.
All of it
Oxygen and nutrients
how cells keep you alive is from your nutrients and from your stomach
