PHYTOPLANKTON
Tiny ocean algae that drift with the currents and use sunlight to make their own food (photosynthesis). As they eat sunlight, they release oxygen and become the first bite in the ocean food chain.
Why it matters: They kick off the marine food web and pump out tonnes of oxygen.
Fun Fact: Their giant “blooms” can be seen from space like swirly green paint.
Say it like this: FY-toh-PLANK-tuhn
Your turn: Draw a page of tiny dots... boom, you’ve made your own plankton bloom!
We have something for you: read Sophia's article about the mighty plankton and how it helps us to breathe and live.
POLLUTION
Unwanted stuff in the sea, like rubbish, chemicals, extra noise, or too much light/heat. It can wash off the streets into drains and rivers, blow in with the wind, or spill from boats.
Why it matters: Pollution can tangle or poison animals, make water cloudy or dirty, and stress habitats like reefs and seagrass. Keeping rubbish out and using less harmful stuff helps the whole ocean web.
Fun fact: After a rain, a city storm drain can be a fast lane to the ocean: whatever’s on the street may ride the water all the way to the sea.
Say it like this: puh-LOO-shun
Your turn: I have prepared for you a fun challenge, you can do it by yourself or with friends or classmates. Let me know how it goes. Your friend, Atlas!
