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.
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.
The endless and enormous power of the sun provides life to all organisms on Earth, from the smallest plant to the largest animal. This awesome power is being used today to provide a rich and abundant source of energy in many parts of the world, and to operate machinery and heat and light buildings. Discover how the sun is powering our planet, the technology used to harness it, and what the future of solar power could be.
Our planet’s weather offers some incredible solutions to our growing energy needs, and one of those solutions is wind power. Offshore and onshore wind farms are an increasingly familiar sight in many countries around the world. Wind farms tap into this clean, sustainable, and renewable form of energy. Find out how wind power works, where in the world it is being used, and how this green energy supply could be one answer to the energy problems that face us today.
In the search for oil and gas, we have drilled deep beneath the ocean’s surface and the ground to tap into the energy wells trapped there. Today, we need more energy than ever before in our history, but the oil and gas fields may soon dry up. One option being considered is fracking. Rock is fractured underground in order to reach deposits. Discover how people use fracking to harness the before-unreachable supplies of gas and oil beneath Earth’s surface, the challenges of this form of mining, and the controversies surrounding it.
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.
Agricultural engineers are in the front line in the challenge to provide a secure food supply for our world.

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.
Earth's surface is constantly being changed by heat, water, ice, salt, plants, and animals. Sometimes the changes are destructive to human activities such as farming and the building of structures. This interesting title shows the different ways people try to stop or reduce this change in the land. Examples feature such structures as dikes to hold back water and windbreaks, and adding shrubs, grass, and trees to an area of land to prevent erosion. Teacher’s guide available.
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.
