Modern transportation lets us travel farther and faster than ever before, but these developments have come at a cost. This book explores ways we can move around without harming the planet. Case studies show how scientists are working on cleaner fuels and new forms of transportation in order to prevent pollution, which affects people’s health, and greenhouse gases, which contribute to climate change. Find out how we can contribute by changing our own transportation habits.
The Internet gives us information at our fingertips and puts us in touch instantly with anyone in the world. It reduces our need to use paper or travel long distances to meet, but its growth has come at a cost. Find out how we can stay connected without harming ourselves or the planet in this insightful look at the Internet and social media. Case studies reveal the environmental impact of producing and discarding the computers and other devices we use to access the Internet, as well as the human toll from serious problems such as cyber bullying and online addiction.
Plastic pollution is one of the most urgent environmental problems facing our planet. This timely title shows how we can stop plastics from doing further harm. Find out what plastics are, how they are made, and why they are so widely used. Case studies reveal the negative impact of plastics, especially micro beads and single-use plastics, on the oceans and coasts, as well as in our landfills and food chains.
Modern farming allows us to buy almost any kind of food at any time of the year. But this convenience comes at a cost. This important book shows how we can farm and grow food without harming the planet. Case studies show how scientists are investigating ways to prevent the problems modern farming creates, including pollution from chemicals used for growing crops, clear cutting of rainforests to make space for grazing and farmland, and contributing to climate change by breeding more and more livestock. Useful suggestions encourage readers to find ways to reduce their food waste and packaging.
Most of our energy has come from oil, gas, and coal. Find out how we can heat and light our buildings, travel, and power our computers and devices without harming the planet in this resourceful title. Extracting resources damages the environment, and burning them contributes to global warming, harms our health, and pollutes the air and water. Case studies show how scientists are investigating renewable energy sources, such as wind and solar power, how to make homes and buildings more energy efficient, and how we can use less energy by changing our own behavior.
More than half the world’s population live in cities, and that number is rising. Find out how we can create buildings and cities without harming the environment in this informative title. The growth of cities can lead to overcrowding, pollution from transportation and factories, and the release of greenhouse gases from buildings. Case studies show how scientists, architects, and planners are investigating how to build more energy-efficient houses and more sustainable cities.
