An overview of the dangers deforestation poses to both plants and animals. This video highlights the impact habitat loss has on animals, how it causes their numbers to decrease, even to the point of extinction. The impact it has on humans is also discussed; in particular, how the lack of trees to convert carbon dioxide into oxygen leads to increased air pollution. Teacher notes: You could ask your students to look at habitats and food chains and what could happen if deforestation continues. They could look at what the term “extinct” means and investigate what has happened to other species of animals that have become extinct. They could then make posters, warning people about the dangers of destroying animals' natural habitats.
