1. How do the earth systems affect each other? Earth systems affect each other by the weather and energy that’s being shown throughout the climate. 2. How can an understanding of environmental science aid in handling natural disasters? It can aid in handling natural disasters by telling us what we going to experience and what’s going to be affected or damage. Also knowing what you have to do to get out of them. 3. What efforts can we make to create a sustainable future? We can stop littering and recycle more to save polluting air. My reaction is that it’s amazing how we don’t know what we should know about natural disasters and what it can actually do.
