Answer: If it once was a forested area, the golf course dangered the living organisms inside the forested area. They could perish, and the population-rate can decrease due to the loss of a home. The ponds could be a potential threat or a bad choice for the ecosystem since it was never there before and it could affect certain animals/living things. (Especially man-made, it could have certain types of pollution or an unreliable water source that could hurt an animal/living thing if they consumed it.)
