Clip Description

There are a number of organisations and charities that help the natural world by protecting habitats and wildlife. For example, the World Wildlife Fund (WWF) is currently undertaking conservation work in over 100 countries, and has helped bring several animals back from the brink of extinction – including mountain gorillas, giant pandas and tigers.

In this fascinating clip, we learn that orangutans are critically endangered. This means that they could soon disappear from the wild altogether. Fortunately, a number of charities and organisations are working tirelessly to protect orangutan populations in both Borneo and Sumatra. Why do you think the word ‘orangutan’ means human of the forest? Watch the clip to find out.

Quick Whiteboard Challenge

  • Female orangutans only give birth to a single baby (twins are extremely rare) about once every 8 years – the longest time between births of any mammal on earth!
  • Female orangutans live between 30 and 40 years in the wild.

Around how many babies might a female orangutan have in her lifetime?
