Among the first people to live on the ocean were fishermen and sailors who spent months or years on ships, exploring or fighting in wars. Today, people live on the ocean for scientific study, work, or simply for fun. There are even entire villages that live by floating on the ocean. Through accessible text and vibrant photographs, young readers will understand how life on the water has changed over time and what the future holds. As land-based populations increase, resources dwindle and pollution levels rise. People are looking to the oceans as a more permanent solution, considering ideas like floating cities and undersea habitats. This book will intrigue young readers and help them to look at the oceans in a new, open-minded way.
