Hi Y11,
You have done work on food production recently and uses of microorganisms. You now need to move on to looking at how humans affect the environment, and I would like you to start this by looking at the causes and consequences of global warming.
4.11 understand how human activities contribute to greenhouse gases
4.12 understand how an increase in greenhouse gases results in an enhanced
greenhouse effect and that this may lead to global warming and its
consequences.
Here are some helpful links. Please let me know which of the links/resources (including your textbook) are the most helpful to you. There is lots of overlap here with Geography, so it would be great to see the geographers helping other members of the class!

Enjoy!
