What is the importance of energy in points?
Energy is essential to life and all living organisms. The sun, directly or indirectly, is the source of all the energy available on Earth. Our energy choices and decisions impact Earth’s natural systems in ways we may not be aware of, so it is essential that we choose our energy sources carefully.
How does energy impact the world?
All energy sources have some impact on our environment. Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable energy sources by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions.
How do humans affect the flow of energy in the community?
Humans influence energy flow and are modifying the energy balance of Earth’s ecosystems at an increasing rate. Changes in the availability of energy affect ecosystems. When humans modify the energy balance, we impact the ability of the ecosystems to react and adapt to variability in the environment.
