What happens as humans use more land for development
​

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

What happens when humans use more land for development is that the air pollution gets bad, and there is over population. This also happens to destroy animal habitats.
