On a warm summer day in August, you decide to go for a walk through a new housing development that was built near your home a few years ago. As you walk by the pond that's in the center of this development, you notice an unpleasant smell
Then, you see that the pond is full of green algae, and there are dead fish floating on the surface. This is a pond that used to be clean and clear, and you used to play in it as a child. What could have most likely caused this change? A) Too many people are discarding food and other wastes in the pond, causing increased algal growth. B) Lawns are being overfertilized, causing excess fertilizer to wash into the pond, stimulating algal growth. C) The low reflectance of the surrounding area is heating up the pond, causing increased algal growth. D) The salting of the roads during icy conditions in the winter has resulted in the runoff of salt and thus stimulated algal growth.
