What are the impact of modified ecosystem?

Relatively small changes in keystone species and functional groups will have greater repercussions on ecosystem process than diversity as a whole. Downsized communities accelerate population, energy, and nutrient turnover rates, increase resilience, decrease resistance, and reduce overall productivity.

How do humans affect ecosystems and the environment?

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.
