As the world’s population grows every minute, there are more and more mouths to feed.  In fact, there are so many mouths to feed that ‘overpopulation’ is now a big concern for our planet’s future. 

Algae

SeaweedAlgae is the green slime you see in ponds or in a fish tank and the long brown/red/green strands of seaweed you see on the beach or in rockpools.  Already millions of people around the world eat seaweed from Japan to Chile, South Africa to Belize and even in England.  In fact you've probably eaten food with seaweed in it and not noticed it as chemicals from seaweed are used in many sweets, desserts, meat products and even drinks!

The benefits of seaweed are many.  It is very nutritious as it has lots of good minerals and vitamins for the body.  These include vitamin A, which helps fight off colds and viruses and calcium which is good for your bones and teeth.  Seaweed is also easy to grow and doesn't take up precious land space as it's grown in water.  It grows quickly and can even grow in polluted waters and in places where normal food crops wouldn't survive.
