How does noise pollution from traffic affect the environment? What animals does it specifically affect?
Answer 1:

I have heard in the news that marine mammals, such as whales, have been negatively affected by noise pollution in the oceans, which makes it difficult for them to find their way and find mates. An article I found

animals-affected
suggests that military ships' sonar is causing marine mammals to dive deeper and they die from the "bends", when too much nitrogen gas gets into their blood.

Before reading your question, I hadn't considered the noise effects of car traffic, but I found some interesting articles on the internet, such as this one

songbirds
, that explained how songbirds have actually changed their songs in response to noise pollution.

There's a very in-depth summary here
nonoise
of the many effects noise pollution has on wildlife. It lists startle responses in reindeer, cessation of milk production in dairy cows and decreased fertility in rats. It looks like there are a lot of animals affected by noise pollution and many ways that these animals can be affected.

P.S. 10th grade seems like a good time to learn the difference between "effect" and "affect". "Effect" is a noun and "affect" is a verb. These two words get used a lot in science, so it's important to know the difference and be able to use them correctly. To go along with your question, you could say that noise pollution has an EFFECT on animals, and specifically, whales are AFFECTed by sonar.
