please raise your hand if you enjoy

snorkeling or diving or would like to

have that experience someday well I

think you and I have just made a

connection we love hanging around in the

ocean well my life in the ocean actually

began as a snorkeler but one day a close

friend said to me hey George oi and by

the way that’s my nickname I think you

should go get a diving certification

because the things that you see deeper

down in the ocean can be much more

interesting than what you’re seeing

right now as a snorkeler and that day

another dive guide came to me and said

hey miss would you like to join us for

this dive because all you need is this

discovery dive which doesn’t require any

certification for a moment I thought

about it and with a little bit of

reluctance I strapped on a 40-pound tank

on my back with the best and my slippers

I took my regulator up into my mouth go

I leap into the ocean I saw something so

far away that was a big sea turtle

greeting me at that time I got hooked

and addicted to diving because the

things that you see down there is so

spectacular and so unbelievable that it

is not the same as what you see in the

aquarium or at SeaWorld and I strongly

recommend that you go try to discover

dive if you can in your life and so one

day I did go get my certification and

learn to manage the tank on my back and

to control my breathing just like in

meditation and I finally realized – why

I

diving I was a beginning diver I used to

take underwater photography of larger

animals that we often see in the news or

in the media such as the well shark well

on so many dive trips what the other

people were all looking for manta rays

and sharks and sea turtles I discovered

something that was many million in

zillion times smaller than those larger

creatures and I felt so much in love

with it because it should also be

protected as much as these larger

animals and this tiny creature is called

this word right here which I’m gonna be

talking about today and you must all

wonder what does this word mean you know

when I introduced this were to my

students and they were asking me is

there that tree or a tree branch without

any clothes on and you know what two of

my students drew this right here well

you know well this word is actually

pronounced nudie bronc can you please

say this word with me nudie bronc and

this is what a nudie bronc

looks like this and this is what I

discovered in every dive and I can keep

clicking there’s so many different forms

of shapes and sizes of these sea slugs

they’re so beautiful I can’t wait until

my night spring trip that’s coming up in

two months because I’m gonna meet more

and more of them there’s so many of them

well I might not be a marine biologist

but let me just briefly tell you what

they are

nudee bronze ashley mean on

cover lungs which means that they

breathe with their external gills they

are marine gastropod molluscs that live

everywhere in their ocean waters around

the world and their vibrant colors

pretty much come from the food that they

eat such as corals sponges

LG’s sometimes even their own eggs and

their need upon friends and their wild

colors pretty much tell their predators

hey you back off I don’t want you to

come and eat me here and the cool thing

is that whenever I go in to look for

their head and where their eyes are

they’re so tiny and that means they have

really poor vision and they only see

bits or shadows here and there and one

time I even saw them fertilizing excite

those in beautiful spirals and they look

like a bunch of ribbons and so many

years that I have been reading so much

about nudibranch book and I actually had

this one that I loved the ping through

the pages there’s so many photographs

that are so colorful I learned that

there are so far about 3,000 identified

species of nudie bronze around the world

but yet there’s so many more still

waiting to be discovered in their

mysterious oceans and it’s so small that

it’s also camouflaging yourself that it

is so hard for divers to see them when

I’m talking to my friends who are divers

around the world on my trips they have

been reporting to me that over the years

it has been coming very challenging to

spot them why is it because of their

larger predators like sea turtles or

fish that have been eating more and more

of them the truth is their greatest

predators are not from the ocean we the

human beings have been the largest

threat to these newly Broncs

this is due to water pollution loss of

marine habitats due to unsustainable

fishing practices biodiversity decline

and also what I see all the time when I

go down diving which really bothers me

global warming that has been damaging

corals where the nudibranch live or eat

and when I was researching online more

about the coral reefs it is so

surprising that according to the World

Wildlife Fund that about a 1/4 of our

coral reefs around the world are damaged

with another two thirds that are in

serious threat so if this continues does

that mean that the gnudi Brow’s are

going to become extinct so does that

mean I’m gonna not see them anymore my

next question for you is please raise

your hand

if you have seen a piece of garbage or a

litter around your living working or

school environment for the past week

yes and you must have felt a little bit

uncomfortable or uneasy about it when I

go diving each time this is what I find

and that’s only one time a pile of

garbage in one hand that comes from all

over the place and how do you think the

new Bronx will feel about this in their

living environment before I became a

diver I’ve never imagined that there’ll

be so much trash so far down in the

ocean and at that time I imagined that

as if so much trash have traveled all

the way back down to me in the ocean

while I’m diving it is so true that our

human actions have been the worst threat

to the needy Bronx it is so easy to

forget about the larger the smaller

marine habitats when the media usually

focuses on their larger ones so why is

it so important for us to care about

these new debounce when it looks like

I’m the only one here who cares about

them more than anyone else in the world

well let me just tell you something how

we humans benefit from the gnudi Bronx

first divers like me love to go down and

see nudie Bronx to take underwater

photography so that we can produce

artistic portfolios divers congregate

together in so many different

communities online or even on their

trips to discuss about how they behave

and possible newly discovered nudie

Bronx moreover according to science

journals like life science there has

been reports where researchers have been

gathering data from the sea slugs to

study their brains for the simple

nervous system on the processes of

learning and also do you know that nudie

Bronx have become – the key to

developing new medicine to help us

humans in many many ways so that put us

humans in the community with the nudie

Bronx even if you might not be a diver

so it is time for us humans to cooperate

together in helping these new debunks

and to save them so how can we do that

well I I came up with this acronym for

you so easy for you to remember and it

is called s l ug slug after the nudie

rugs so what does that mean S is for

sharing

L is for lowering U is for understanding

and G is for guiding now because I am an

elementary school teacher and I teach

grade four and my students there’s some

of them here who have come come up with

a lot of gestures for you to remember

and they’re very interesting so they

would like to invite you to stand up

because they would like to teach you how

to remember that come on let’s stand up

here sitting down everybody longs back

and you know that there is strong

evidence that movement connects to

learning so are you ready

okay so Miss Judy right here would like

you to start from your finger and going

outwards to try s for your mouth to

share information about the needy Bronx

so the information that you learn from

me today please share them with your

friends families and the people around

them and encourage them to also share

that with others so the world becomes

more and more aware of the needy broad

community if you’re a diver please make

sure that you join the Facebook

community such as new debunk central

let’s share and spread the words out yay

next Melinda would like to have you make

a cool post like this and you’re going

to lower the amount of carbon footprints

such as the plastic photos that you use

like your plastic vibe you’re going to

lower this so that it stops entangling

the coral reefs and that’s where the new

Doubront lives and also you get a lower

the amount of electricity that you use

because what does this try to stop

global warming all right next is little

Sophie would like you to grow a pair of

nudie bronc Rhino pours in the form the

Shiva you and this is for understanding

more about the needy Bronx you educate

yourself through online researches

reading books and even talking to others

or watching films or documentaries so

you understand more about the community

of the needy Bronx Anika would like you

to hold yourself in the front and guide

other people you’re making a jeep to

guide the people around you model

positive behaviors above and below the

ocean waters please encourage the

younger generation to reduce recycle and

reduce reuse and recycle and we’re going

to do this all and I want you to give

each other a high-five because you had

just made a first step in saving the new

Diwan community down now I today have a

goal to put the human community with the

nudibranch community and I have found a

purpose in my life and where I belong in

the world by putting these two

communities together into one how are

you going to take action starting from

today and building that one community

let us share this planet together so

that our one community can live with

love happiness and health

thank you [Applause]
