Humans can negatively impact the geosphere. Humans mine landforms in order to get raw materials to sustain factories. This mining can
contaminate the soil with chemicals.
Humans can negatively impact the hydrosphere. Farmers use fertilizer
to improve their crops. The fertilizer washes into streams and may increase
the growth of algae. When the algae decay, oxygen is used up, and no
longer available for other organisms. The streams become "dead"
Humans can negatively impact the biosphere. Humans cut down trees for their wood. This causes entire forests to disappear and leaves many animals without habitats.
Humans can negatively impact the atmosphere. Humans raise large amounts of livestock, which produce large amounts of methane gas. The methane gas contributes to global warming.
