What this set covers
Farming methods, trade and disease spread are the focus. The Green Revolution, GM crops, intensification, food miles, agribusiness, Fairtrade, aquaculture, endemic and pandemic disease, vector-borne and zoonotic disease, diffusion types and herd immunity appear.
- Common mix-up
- Students often confuse endemic, epidemic and pandemic: endemic disease is constant at a stable level in a region, while a pandemic spreads across several continents or worldwide.
- Revision tip
- Trace how a disease might spread by contagious diffusion and then by hierarchical diffusion, and say what herd immunity does to the chain of transmission.
