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.
This fascinating book, illustrated with colorful photographs, makes the topic of symbiosis easy and fun. It looks at the positive, negative, and neutral effects that result when different kinds of animals interact with each other. Symbiotic relationships highlighted include birds and fish that clean parasites off other animals, bacteria that help keep animals and people healthy, mosquitoes that pass diseases such as malaria, predators that hunt prey, and scavengers that help clean the earth. Other examples of symbiotic relationships include several kinds of animals. Students are asked to illustrate symbiosis in human relationships that are similar to those found in nature.
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.

From trees and plants to bugs and birds, every living thing on Earth is a form of energy. And all living organisms create energy, too, in the form of their waste. The energy of living things is called biomass, and it can be used to power the things that we need in our everyday lives, from washing machines, cars, and computers to the heating and lighting used in our buildings. Find out more about biomass, how it is sourced and used, and why this form of energy could help us find a more sustainable way to power our lives in the future.
How are many people in different places around the world learning to live in a green and sustainable way? Find out how human activities such as driving cars and wasting energy are threatening our environment and putting the future of our planet at risk. Discover how people everywhere are choosing to live more sustainably by recycling, using green sources of energy, car-sharing, and reducing air travel.
We live in an energy-rich age, in which we can turn on a light with the flick of a switch or drive anywhere by turning a key. But, our vehicles, factories, and power stations, which create the electricity needed to light and heat our buildings, pump carbon dioxide into Earth’s atmosphere. Carbon dioxide overload from these human activities is making our planet hotter and hotter - and is causing the Earth's climate to change. Find out what scientists are doing to find sustainable new forms of energy that will secure our planet’s future.
Earth has a limited supply of fossil fuels, and in the near future this supply will come to an end. However, more people live on the planet than ever in its history - and they all need energy. One of the ways in which we can meet this increasing demand for energy is through nuclear power. Nuclear power stations do not drain our planet of its resources, and they can supply a seemingly limitless source of energy. Discover more about nuclear energy, how it is created and harnessed, and the controversies and challenges that surround it.

Real-life examples help students understand key concepts related to this important profession. With an overview of the engineering design process, readers are encouraged to apply the same steps into their own agricultural engineering challenge.
Animals are endangered in many kinds of habitats and for different reasons. This intriguing book looks at why some animals have become endangered due to changes in their habitat. Examples include animals in the Arctic that rely on ice for hunting face the challenge of melting ice due to climate change, the populations of animals born only on particular islands and nowhere else are shrinking, and many kinds of ocean animals are being poisoned by water pollution. Ideas are included to encourage readers to help protect these endangered animals and their habitats.
This entertaining book shows how animals communicate to share information, attract mates, or scare away enemies. They sing, growl, howl, spray smelly scents, and make their body parts bigger. Students will have fun learning about these communication skills and be asked to compare their communication methods with those of animals.
Animals adapt, or change, to stay alive. Adaptation can happen in an animal’s body or in the way it behaves. Some adaptations have taken place over many years, and others are caused by changing habitats due to the actions of people. This informative book shows animal adaptations due to changing climates, habitat changes, and opportunistic behaviors that help animals survive, such as the creation of new species. The coywolf, for example, is a new species. It is part coyote and part wolf, and has a much greater chance of survival than either of the animals that created it.
People have learned a lot from animals and copied many of their ways of surviving. This interesting book details many, often surprising, examples: bird flight and airplanes; defensive equipment such as helmets and turtle shells; strong spiderlike threads for surgeries; heating and cooling systems such as those created by termites; camouflage patterns on uniforms or vehicles in battle; and animal prints copied in fashions and decorations.
