Explore the remote Southern Ocean in this beautifully illustrated children’s book, for readers aged 9+.

Icy and mysterious, the Southern Ocean stretches across the bottom of the Earth, surrounding the continent of Antarctica. With its freezing waters, harsh winds and towering waves, until recently only the bravest explorers sailed its stormy seas. Today, tourists flock to see the ocean’s unique wildlife of penguins, seabirds and blue whales. But along with human visitors come human-made problems, including global warming, pollution and overfishing.

The oceans make up Earth’s biggest habitat. More than 70 per cent of Earth’s surface is covered by oceans and seas and they hold more than 97 per cent of Earth’s water supply. Oceans drive the world’s weather, provide half of the oxygen we breathe and provide food and livelihoods for more than a billion people.

Blue Worlds explores each of the world’s five oceans and major seas in detail, looking at the different features – from wildlife and weather to landscape – that make them all individual and unique. It also looks at the threats that they face, such as global warming, overfishing and pollution.

What are rainforests and why are they important? This book looks at the fragile ecosystem and its destruction over the second half of the 20th century. It considers whether there can be a balance between people's needs and the well-being of the forests themselves. The book talks about the causes of the destruction of rainforests and the positive projects that are already happening to conserve the rainforest. It also looks at the future of the forests. Opposing viewpoints are given throughout to provide opportunities for discussion and debate.

Part of a series which covers a wide range of subjects, this book provides information on the seas and oceans, what the ocean floor looks like, which animals and plants live in which parts of the oceans, what treasures can be found in the seas and what part humans have to play in the conservation of the oceans.;The book features a gatefold, which opens up to reveal the amazing variety of life in the oceans, from the seashore to the dark, murky depths of the ocean floor. In addition, there is a fun quiz for children to test their knowledge.
