小演讲water under the ocean

WATER UNDER THE OCEAN

Good morning/afternoon ladies and gentlemen/teachers and fellow classmates.
What do you think of when you look at the deep ocean? Do you think that it is boring? Well, i beg to differ. There are millions of species of marine animals living in the ocean and most are precious to our food pyramid! These are important and as fascinating as anything else! So, next time, go scuba-diving in the ocean and discover what you have been missing! Thank you!
