Which statement best describes a common environmental consideration for wind and ocean energy?

• A. They have no wildlife impacts.
• B. They only affect air quality.
• C. They always improve habitats.
• D. They can have wildlife impacts such as disturbance and habitat disruption.

Answer: (D)

Wind and ocean energy projects introduce new structures and activities into natural habitats, so a key environmental consideration is how they affect wildlife and habitats. These installations can disturb wildlife and disrupt habitats in several ways. For birds and bats, turbines present collision and disturbance risks, which can reduce populations or alter flight patterns. In the marine environment, offshore devices, cables, and the associated construction noise can affect marine mammals, fish, and seabed communities, causing changes in movement, communication, or feeding. Construction and ongoing operation can also change sediment movement, benthic habitats, and the overall structure of the seabed, leading to habitat disruption for organisms that rely on those areas. While wind and ocean energy can reduce air pollution compared with fossil fuels, they do not inherently improve habitats, and they do carry potential wildlife impacts. Therefore, the statement that best reflects a common environmental consideration is that these energies can have wildlife impacts such as disturbance and habitat disruption.
