Identify and explain one way humans are altering aquatic biomes.
Must explain how humans are causing this and how this is impacting the biome.
•Pollution
•Overfishing
•Introduction of invasive species
•Acidification
•Habitat Alteration
•Overuse

Explain one way that humans are impacting the tundra biome.
•People encroach on it to build or drill for oil.
•Perhaps the greatest danger, however, comes from climate change.
•Warming temperatures could disrupt the cold tundra biome and the life in it, as well as thaw its underlying permafrost, releasing greenhouse gases that would further accelerate global warming.
Every continent has this biome.

Identify and explain a human impact on the grassland biome.
•Introducing grazing animals to the grassland's environment such as cattle, sheep and goats force the native animal population to compete for food.
•They also trample the ground damaging root systems and soil structure.

(75% of ice-free land has been altered)
