10. Did You Know…?
There is a greater variety of life in the world’s oceans than
anywhere on land.
All our oceans are connected, so we need to keep
them all healthy!
There are many threats to marine life, including plastic pollution,
overfishing and global warming.

11. How Are Species Important to the Ecosystem
They Belong to?
Ocean ecosystems contain a variety of food webs and food chains, where each
element relies on another. They are in balance. Here is an example ocean food
chain.
sunlight
phytoplankton
krill
small
fish
tuna
shark

12. Activity : Food Webs
Provide each student one
copy.

13. Apart from the producers (phytoplankton), which use sunlight to make their own food,
each species of animal relies on another for survival. What do you think would
happen if all the tuna were removed from this food chain below?

14. If all the tuna were removed, the shark would have nothing large enough to eat.
With nothing to eat, the shark would not survive.
With no tuna, the small fish have no predator so would grow and grow in numbers.

15. In this scenario, the small fish would now eat the krill faster than they can reproduce.
Eventually, the krill would all be eaten, meaning the small fish would have only
phytoplankton to consume.

16. With the small fish continuing to grow in numbers and no longer having krill to eat,
they would eventually consume all the phytoplankton too. As the phytoplankton die
out, there is no new food being produced in this food chain. The small fish now have
nothing to eat and can no longer survive.

17. What we are doing?
Overfishing
This is when too many fish are caught. If people catch too
many fish, this affects many living things in the ocean.
Living things all need to survive. Some creatures that live in the ocean
eat plants, others eat different living things. This is called a food chain. If
one part of the food chain is broken (like a type of fish being removed
from the ocean by overfishing), then other things may not survive
because they won’t have food.

18. Overfishing
Look at the diagram below.
If one is removed then there could be a big problem.

19. What Are We Doing?
• Big pieces of plastic in the sea, like plastic bags, can harm the
creatures as turtles and dolphins can get tangled in them.
• Sometimes, sea creatures eat plastic as they mistake it for food.
• Plastics can also start to break down into tiny pieces in the sea;
this means that plastic gets into our food chain and lots of living
creatures start to eat plastic, even you and me.
Plastic pollution
This is when plastic gets into the seas
and pollutes, or harms, the living things.

20. Plastic Pollution
Many plastics do
not biodegrade.
• Plastic is a very
useful material,
but it is very hard
to get rid of.

22. The oceans and seas are so vast
and deep that we still don’t know
how many species live there but
scientists think it could be over
two million.

27. MARINE LIFE
• There are seven different species of turtle
(which are all reptiles) and none of them
have teeth.
• The leatherback is the largest species
and can grow to over two metres long.
Time for Change
Many sea turtles eat jellyfish, and a clear plastic bag
suspended in the water can resemble one. Many
Organizations are working to rescue injured turtles and
release put them back into the wild once they are healthy.
SEA TURTLE

28. MARINE LIFE
• Crabs are invertebrates, they have
no backbone.
• They are related to insects and
spiders, but they have many legs (10
in fact!)
Time for Change
Overfishing ! Some countries are implementing fishing
regulations to protect our marine life and ecosystems. You
can try eating less marine animals too.

29. CLIMATE CHANGE
Harmful gases are very
damaging to our climate.
These gases are produced by
cars, vehicles and the
factories that make some of
our toys.
When these harmful gases
rise up into the air, they get
trapped in the layer protecting
our Earth from the Sun (called
the atmosphere). When the
Sun shines onto the layer of
gases, they get hotter and
hotter and heat up our Earth
too much. This is called
global warming.

30. IMPACT OF CLIMATE CHANGE
ON MARINE LIFE
These changes are
impacting marine life.
Rises in temperature and
acidification can lead to
the loss of marine habitats
and species.

31. DID YOU KNOW?
The Arctic is warming about
twice as fast as the global
average, causing the ice
that polar bears depend on
to melt away.
Loss of sea ice also
threatens the bear's main
prey, seals, which need the
ice to raise their young.
END

32. DID YOU KNOW?
Due to the dramatic
loss of sea ice,
several colonies of
emperor penguins
in Antarctica face
"quasi-extinction"

33. CREATURES & THEIR HABITATS
• Dolphins are
mostly found in
Australia.
DOLPHINS

34. OCEANS AND CREATURES IN THEM
• They live in the arctic
sea

BEARS

35. Marvellous Marine Mammals
• Whales can be found all over the world.
Some species migrate (move from one
place to another in different seasons) to
find food and have young.

Did You Know...?

36. How Can You Help?
There are lots of ways we can help protect our beautiful blue planet:
Recycle things, rather
than throw them away.
Eat sustainable fish (that
means fish that isn’t
allowed to be overfished,
so we don’t run out).
Stop using lots of
plastics that could end
up in the seas (even
wet wipes can contain
small amounts of
plastic).
Help spread the message
about looking after our
oceans and recycling.

37. Inspiration
Artists have already been making sculptures out of recycled plastic.
Take a look at these for inspiration.

38. We Need to Stop!
Global warming isn’t good for our Earth as it heats
everything up. It causes ice to melt in the Antarctic and
sometimes this causes floods in other parts of the world.
Flooding and rising sea levels means that beaches
become smaller. This poses a danger to many
animals, such as the loggerhead sea turtle, which lays
its eggs in a nest on the beach.
Additionally, the nests need to be the perfect
temperature, as this affects whether the turtles
will grow to become male or female. If the
temperature keeps rising, more female turtles
will be born than males. This increases the risk
of this wonderful, already vulnerable species,
becoming extinct.
