Rainforests cover around 8 percent of the world's land surface, and they require a lot of living and nonliving things to coexist together to thrive. When these things coexist, a process called "cause and effect" happens--referring to the way each action affects another, ultimately causing different events to happen. And sometimes these events are unpredictable! From food chains to deforestation and climate change, many factors can cause a lasting effect on rainforests, which readers uncover throughout this volume. As they're guided by visuals and arrow diagrams, readers comprehend the weight that every action--even small ones--can carry in a rainforest.
