Land Use & Human Impact

How does the expansion of urban development into rural areas affect natural populations in the environment?

• Death rates of the natural populations will decrease.

• The amount of area available to producers will increase.

• The biodiversity of the natural populations will increase.

• Resources available to the natural populations will decrease.

Why is urbanization needed?

• The human population continues to grow, so the space is needed to support the growth.

• The human population continues to decline, so the space is needed to support the growth.

• Humans like larger cities

• The human population continues to grow, so the space is needed for biodiversity.
