There used to be many species of rhino but now there are only five. All are at risk, some are critically endangered. But what can you do to help?

• Raise money for rhino charities. RWS presenter Nick Baker took part in the gruelling Marathon des Sables for Save the Rhino Trust. If that sounds a bit extreme, there are many other ways to help.
• Raise awareness about the use of rhino horn in traditional medicines and for decoration.
• Tell friends and family about the situation or give a talk at school.
• Don't buy products or souvenirs made from endangered species, for example ivory, rhino horn, tortoiseshell or coral.
• Rhinos need a bit of space! Their habitat can be destroyed by logging or building. Buy wooden products from sustainable sources and use recycled paper.
• Adopting a rhino as a birthday or Christmas present is a good way to support conservation work.
