What are the impacts of population growth? Can our planet support the demands of the ten billion people anticipated to be the world's population by the middle of this century? While it is common to hear about the problems of overpopulation, might there be unexplored benefits of increasing numbers of people in the world? How can we both consider and harness the potential benefits brought by a healthier, wealthier and larger population? May more people mean more scientists to discover how our world works, more inventors and thinkers to help solve the world's problems, more skilled people to put these ideas into practice? In this book, leading academics with a wide range of expertise in demography, philosophy, biology, climate science, economics and environmental sustainability explore the contexts, costs and benefits of a burgeoning population on our economic, social and environmental systems.

Everything is made of stuff. Some things are made of paper, like this book. And some things are made of PLASTIC. If you look around you, plastic is everywhere. Even in places where it's not meant to be. If it drops to the ground, it doesn't rot away - it sticks around for ever. Our world is drowning in plastic, and it's a big problem. Award-winning author-illustrator Neal Layton is here to explain where plastic comes from, why it doesn't biodegrade, and why that's dangerous for animals and humans alike. But he's also FULL of ideas for how you can help! From giving up straws in juice cartons to recycling all we can and taking part in a beach clean, A Planet Full of Plastic will get young readers excited about how they can make a difference to keep Planet Earth happy. This brilliant non-fiction picture book, illustrated in Neal's trademark collage style, is perfect for readers aged 5-7 who love nature and want to help the environment.

"A project of the Competitive Enterprise Institute." Includes bibliographical references and index.

With food supplies tightening, countries are competing for the land and waterresources needed to feed their people.

Four people are born every second of every day. Conservative estimates suggest that there will be 10 billion people on Earth by 2050. That is billions more than the natural resources of our planet can sustain without big changes in how we use and manage them. So what happens when vast population growth endangers the world’s food supplies? Or our water? Our energy needs, climate, or environment? Or the planet’s biodiversity? What happens if some or all of these become critical at once? Just what is our future? In Tipping Point for Planet Earth, world-renowned scientists Anthony Barnosky and Elizabeth Hadly explain the growing threats to humanity as the planet edges toward resource wars for remaining space, food, oil, and water. And as they show, these wars are not the nightmares of a dystopian future, but are already happening today. Finally, they ask: at what point will inaction lead to the break-up of the intricate workings of the global society? The planet is in danger now, but the solutions, as Barnosky and Hadly show, are still available. We still have the chance to avoid the tipping point and to make the future better. But this window of opportunity will shut within ten to twenty years. Tipping Point for Planet Earth is the wake-up call we need.

Move to another planet? Sounds interesting! In our imaginary spaceship, let's check out the planets in our solar system. Mercury is closest, but it has no air, and it's either sizzling hot or bitterly cold. The atmosphere on Venus is poisonous; plus, human beings would cook there. Mars might work, but you'd always have to be in a protective shelter. And if you got to the outer planets, you couldn't even land as they are mostly made of gas! Our home planet is looking good. Why is Earth so comfortable for plants, animals, and people? As Robert E. Wells explains, it's because of our just-right position form the sun, marvelous atmosphere, and abundant water. Our planet is very special and perfect for us, and that's why we must do all we can to keep Earth healthy.
