An entertaining overview of some of the ways we can help to protect plants and nature. This video looks at ecology, nature reserves and conservation, while also refreshing some of the topics covered in the rest of the series. Teacher notes: You could ask your students to come up with a list of things that humans do that have both a positive and negative impact on the environment. For example: pollution, littering, deforestation, animal conservation, growing vegetables. They could then make a poster highlighting the things the school can do to protect plants and nature.
