Plastic pollution presents a huge ecological issue as it floats, doesn't decompose and is composed of toxic elements.
Facts about the test: The AP Environmental Science exam has 80 multiple choice questions and you will be given 1 hour 30 minutes to complete the section. That means it should take you around 17 minutes to complete 15 questions.
