Explanation:

• Dams are constructed by humans. They store water, which can be used to generate clean hydro - energy. Also, they help in flood prevention by regulating the water flow.
• A density - dependent limiting factor (like competition for resources) has a negative impact on population size and is not related to these impacts.
• A hurricane is a natural disaster and has mainly negative impacts like destruction, not positive impacts like water storage, clean energy, and flood prevention.
• Beavers can build dams (on a small scale in their ecosystem), but the question is more about large - scale human - made dams which have a significant impact on society in terms of water storage, energy, and flood control.

Answer:

positive impacts of dams on society
