Biggest consumer=animal product
Smallest consumer=starches
increase in meat production=increase in water-->demand of water increases with diet NOT population |

Definition
| lack of plant diversity, no variation |
|
|
Term
|
Definition
| diversified crops and polyculture interbreeds individual plant lines to incorporate variation in the genetic line. This variance ensures that at least some portion of the plant population would survive in adverse conditions like drought, wheat rust, or other plant diseases. Monocultured lines do not have this variation because they are not interbred. Polyculture crops are more beneficial because they are less likely to be eliminated entirely by resistant fungus or bacteria. |
