I agree with the person above - I'd say the correct answer is B. The greenhouse effect is changing Earth's atmosphere.
A is incorrect because the excerpt says that the atmosphere keeps the Sun's heat from leaking away into space. C is incorrect because it is the greenhouse effect that keeps the planet warm. D is not even mentioned in the text, which means that only B is correct.
For people to stop littering the first step is.. (then add on what you think.)

Example 2: The first step for people to stop littering is to show an example about what could happen to the world, it could cause diseases towards animals but also to people as well.
Hope this helps :)
