Algae are plants like seaweed that tickles your feet when you’re paddling in the sea!

But did you know that many species of algae have many astonishing properties?

For example, spirulina is full of proteins. This brown alga has twice as much vitamin C as oranges!

The Japanese eat 7 kg a year, whereas elsewhere, people are only just starting to taste it.

It also turns out that algae are ideal for making beauty creams.

And because they can thicken and jellify, they’re used to make candy.

We now know how to make fuel and plastic from algae.

In France, a new company now uses algae to make smart phone cases!

But certain algae also cause problems. You may have heard of “green tides”.

Thousands of tons of algae get washed up regularly on the beaches of certain bays with shallow water.
