Technology Takes on Nature

Human impact on the environment is often difficult to track, but not when it comes to dams. These massive engineering projects create huge changes in our waterways and how we use them. Full-color photographs illustrate how engineers create water reservoirs and create hydroelectric power using a variety of dams. Readers will also see how dams create recreational activities for humans while others directly impact animal habitats and require further human engineering to safely bypass these water barriers.

Traveling by boat in cold climates would be extremely difficult without icebreakers. These special boats help create paths in ice that allow other vessels to travel frigid, ice-filled waters to deliver people and supplies to places often inaccessible without their hard work. Readers will dive in to explore how icebreakers work and what special tools they have to keep other boats safe in the water. Full-color photographs show icebreakers leading ships to Antarctica and other ice breaking projects while exploring the other places these boats work around the world.
