GCSE Biology Revision: Global Warming and Biogas

You can watch all my videos at www.freesciencelessons.co.uk

In this video, we start by looking at the greenhouse effect and how this is caused by increasing levels of carbon dioxide and methane. We then explore how humans can reduce their emission of carbon dioxide by using biofuels such as biogas. Finally, we compare small-scale biogas generators with large-scale biogas generators.
