5B/C. Pollution Review

Cameron and his sister like to go fishing with their dad on the weekends. They fish at a lake that is downstream from a factory. One Saturday they went to the lake to go fishing and they found that the lake was full of dead fish and had a sign that said “NO SWIMMING.” Using your understanding of the impact of humans on the environment, which was the most likely cause for the dead fish and the “NO SWIMMING” sign at the lake?

• Too many people fished at the lake, so the fish lost their source of food which caused the fish to die.

• People threw a lot of trash into the lake, which made the fish die and the water unsafe for swimming.

• Too many people were swimming in the water, which made the water too dirty for the fish to live in. 

• Pollution from the factory upstream caused the fish to die and made the water unsafe for swimming.
