This important book shows how the use of fossil fuels is changing Earth’s climate and what scientists are doing to find sustainable forms of energy that will secure our planet’s future. We live in an energy-rich age that relies heavily on the burning of fossil fuels. We burn fossil fuels to power our vehicles, factories, and even our power stations, which burn fossil fuels to create the electricity needed to light and heat our buildings. The result is a buildup of carbon dioxide into Earth’s atmosphere. Find out how carbon dioxide overload is making our planet hotter and hotter and what is being done to fight global climate change.
For centuries, falling water has been used in parts of the world to create energy to run grinding stones at mills and irrigation systems for crops. This interesting book shows how the use of this “clean” form of energy, called hydroelectricity, is being expanded to help us build a more sustainable future. Discover how other forms of water-based energy, such as energy from ocean waves and tides, are being harnessed and used to help create electricity to power our homes, offices, and factories.
Foxes, rabbits, mongooses, rats, starlings, turtles, Burmese pythons, and Asian carp are just a few of the invasive animals introduced by people into countries and ecosystems to which they do not belong. This important book describes how these animals are destroying habitats and endangering the lives of native animals, some of which have been brought close to extinction. Students will learn how some arrived accidentally on boats, while others were brought in by people, to be used either as a form of pest control on farms, for hunting or hobbies, or as pets that sometimes get abandoned in the wild by owners. Many native animals, such as raccoons, squirrels, and coyotes have also become invaders in cities, back yards, and homes. Students can research invasive species in their areas and help find ways to stop these wild invaders from taking over the natural habitat.
Wild animals are facing huge challenges in the natural world today. Many are endangered - some critically. This eye-opening book shows how animals are being threatened by habitat loss, climate change, non-native species taking over their habitats, pollution, over-fishing, poaching, collisions with cars and boats, and human diseases. Many recovery efforts are in progress to bring back the populations of some nearly extinct animals and to reintroduce some captive ones to their natural habitats. Readers will learn how scientists are working to save blue iguanas in the Cayman Islands, black-footed ferrets in the Canadian prairies, penguins and albatross in Patagonia, and great apes in Africa. This engaging book also encourages students to compare their life challenges to those of animals in the wild.
