Why are Manatees endangered?

Manatess are constantly getting hurt and killed by powerer boats running into them. This is because manatees are slow near-surfaced swimmers. This problem alone wiped out 12 precent of the manatee population.

Manatees were heavily hunted for in the past because of their meat and blubber. But even still today in the Caribbean and South America they are still hunted.

Prowerboat damage

Manatees rely on seagrass for there diet. Coastal developement such as buildings or structures built along rivers or the coast line destroy seagrass habbits leaving no food for the Manatees.

A major reason why the Sea Turtle population went down is because of the fishing industry. Many boats every day cast their nets out to catch and then sell their fish on the market. But sometimes other creatures get caught in the net such as Sea Turtles. This results in the fishermen killing the turtle or just leaving them in the net to die.

Sea Turtles can sell for a lot of money on the illegal market causing many people to hunt for them. Sea Turtles are very vaulble for their shells, meat, and eggs. Before the law of making Sea Turtles illegal to hunt, many people hunted Sea Turtles which drastically decreased the population of them.

Why are Sea Turtles endangered?

A simple plastic or balloon in the ocean could kill a Sea Turtle. A Sea Turtle might think a piece of trash in the water is food but there is a high chance of the Sea Turtle choking on it, getting tangled in it, or getting sick from it.

What will happen if Whales go extinct?

If Whales were extinct it would effect the ocean negetivaly.

What will happen if Whales go extinct?

- Less ocean plants: This is because Whale feces is like a fertilizer to the plants and gives the plants lots of nutrition

- Less herbivors: Since the plant production has gone down many herbivors die

- Less carnivors: Since most herbivors are prey and there are now less of them, the carnivors will have less prey to eat and many of them will die

Negative outcomes: Since there are less fish in the sea, the fishing industry goes down and lets not forget the Whale watching tourist attractions

What will happen if Manatees go extinct?

Manatees are not even close to a keystone species but if they go extinct they will have a somewhat negative effect on the ocean.

What will happen if Manatees go extinct?

- Less sea grass: Manatees eat mostly sea grass and if they go extinct no one can trim the ocean floor. This is important because sea grass needs to stay short in order to stay healthy

- Less Sharks, Crocodiles, and Alligators: This is because they are predators of the Manatee

-Less fish: Manatees sometimes have moss or sea debris on their back but fish will eat the debris off benefitting both the manatee and fish (this is called Symbiosis)

Negative Outcomes (on humans): No one likes too much yucky sea grass and you heard less fish, that means bye bye fish industry!

What will happen if Sea Turtles go extinct?

If Sea Turtles go extinct many sea creatures will die.

What will happen if Sea Turtles go extinct?

- Less sea grass and seaweed: Sea Turtles mostly eat sea grass but if they are extinct the sea grass wont get trimmed and they will eventually die

- Less sea creatures: sea grasses are homes to many sea creatures and when the sea grass is all sick and dead the sea creatures loose there habbitat and die

- Less predators (Bigger fish): since all the little sea creatures are dead the predators have nothing to eat and they die

Negative Outcomes (on humans): The fishing industry goes down and the ocean becomes alot emptier
