Using any type of energy source can negatively impact the environment. Fossil fuels have the greatest and most damaging impact on the environment, but renewable energy sources can still cause a significant amount of damage—as well as cause unintended future consequences. For example, habitat loss, carbon dioxide emissions, and land destruction are just a few of the negative impacts that arise from using renewable energy sources.

Renewable energies such as wind, solar, and geothermal carry the potential for environmental damage. Wind energy is a relatively clean method for producing electricity because it does not produce harmful emissions. However, this energy source requires a large amount of land. Wind turbines have been known to harm birds and bats. Solar energy also contributes to habitat loss, and making solar panels produces harmful chemicals. Geothermal energy can harm water quality. It can even cause the surface of the land to sink.
extinct organisms; that is, they belong to species that are no longer living anywhere on Earth. (3) The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time.
Cells from the cheek are a type of epithelial cell, similar to skin. ... They can be seen faintly even at 40x (scanning power), but the most dramatic images are at 400x where the nucleus is clearly visible as a dark spot in the center of the cell.
