What is seaweed used to make?

Seaweed can be used as food, and is popular as a snack or light meal in some countries, inlcuding China, Japan and Wales. The Chinese serve shredded and dried seaweed in bowls, whilst the Welsh make lavabread croquettes by mixing it with flour and onions. Seaweed can also be used to make fertiliser, both in dried and in liquid form, for use in agriculture and by private gardeners. It can also be used as animal feed, being extremely high in minerals.
