One of the advantages to using genetically modified organisms (GMOs) is

• bad smells

• livestock can escape

• water pollution due to runoff

• improvement of feeding efficiency

Because global fisheries have dramatically seen a reduction in fish numbers, this technique has been used recently to supplement that loss.

• monocropping

• IPM

• contour farming

• aquaculture

Extensive logging can lead to

• Mudslides

• Deforestation

• Lost of species

• All of the above

Why do limited resources become depleted

• Because people don't care about other lands

• People don't have private property that prevents this

• You wake up thanks to the birds

What's an example of a negative externality

• Sheep grazing too much

• Losing sleep thanks to a shop next door (noise)
