The time to save the planet is now.
Ready? Set? Green! Living green means reversing climate change, but it also means protecting your kids and pets, improving your own health, and saving money. And it doesn’t necessarily demand a radical overhaul of your life–just some simple adjustments, such as switching to healthier cleaning products and driving fewer miles each week.
Written by the visionaries at Treehugger.com, the most heavily trafficked site of its kind,
Ready, Set, Green is the definitive (and recyclable) guide to modern green living. It offers solutions to make your home, office, car, and vacation more eco-friendly. For example:
• Using a dishwasher instead of hand washing will save you 5,000 gallons of water annually.
• Eating less beef will save you 250 pounds of CO2 per year.
• Washing your clothes in cold water instead of hot will save 200 pounds of CO2 annually.
• Replacing three of your home’s most frequently used lightbulbs with compact fluorescent bulbs will save 300 pounds of CO2 every year.
Including advice on how to properly insulate your house, cancel junk mail, and choose fruits and veggies wisely,
Ready, Set, Green will help you
change the future of the planet and restore balance to your daily life.

The Future Is Green
WHAT YOU CAN DO
Look out your window. What do you see? A paved street and electrical wires? Meadows and birds? A farm full of cows? Whatever surrounds you, that's the environment. And whether it was created by Mother Nature or the municipal works department, humans aren't separate from it. Just as hurricanes, floods, and tornadoes have an effect on our well-being, we have an effect on nature, polluting water via our factories and homes, reducing mountains to piles of coal that we burn for energy, packing landfills with our used-up cars and electronics packaging. Luckily, it turns out we also have the power to clean up after ourselves.
At TreeHugger.com, the website dedicated to modern green living, we believe that cutting-edge ideas, technology, and design-and, more important, people with the right attitude-can help save the environment. This book was conceived to help readers develop an understanding of existing eco dilemmas, and to empower them to help reverse the problems. We don't have all the answers; no one does. But we believe that individuals do have the power to "green" the planet. Your dollars count. Your vote counts. Your actions count. And when millions of people do the right thing, it can have a serious impact.
A BRIEF HISTORY OF ENVIRONMENTALISM
In the mid-eighteenth century, the industrial revolution changed life as humans knew it. Local economies that produced and sold goods made primarily from biodegradable parts gave way to economies of mass- produced items that could be shipped all over the world. It was a time of great achievement and hope, but also of great innocence and ignorance-when people could not fathom that natural resources could someday become scarce or even dry up altogether.
By the late 1800s and early 1900s, the need for land conservation became apparent to people such as John Muir and President Theodore Roosevelt, the latter of whom set aside more land for national parks and nature preserves-194 million acres by 1909-than all his predecessors combined. It wasn't until the 1960s, however, that the modern environmental movement was born. Utopian idealists dreamed of living off the land and sticking it to the man. Their goals were lofty, but extremists pushed the movement to the fringe. At the same time, environmentalism became fragmented. Various factions debated the value of the natural environment and its relationship to human progress: Does nature exist to serve humankind, or vice versa? Does man have an ethical obligation to protect nature? If so, should he do so for his own benefit, or should he preserve nature for its own sake?
Today these questions have become scientific and economic queries about biodiversity, human health, and natural capital. Because we now know that we are depleting and polluting our most essential raw materials-such as water, forests, petroleum, and clean air- environmentalism has taken on a new personality in the twenty-first century. We've arrived at a point where philosophical and political issues can be put aside. We know scientifically that we must collectively come together to rethink the way things are done. To our credit, we've tackled other eco challenges: When scientists told us that the ozone layer-the part of the atmosphere that protects the Earth from the sun's harmful UV rays-was being depleted, humans stepped up to the plate and developed solutions to the problem. We can do the same for global warming.
Whether you've picked up this book for altruistic, ethical, or scientific reasons almost doesn't matter. You are part of a critical mass that is shaping the new wave of do-it-yourself environmentalism into a grass-roots social movement that has little to do with baggy hemp pants and tofu and everything to do with intelligent modern living. The next industrial revolution-when the interests of technology, ecology, and commerce overlap-has already begun. Welcome to the bright green future.

OUR ECOLOGICAL FOOTPRINT
You probably already know that everything you do has some kind of impact on the planet. But just how much impact do we have? How often we drive, how much meat we eat, the type of fuel we use to heat our homes, and so on, all contribute to the "footprint" we leave behind. The measure of how our lifestyles affect the Earth and its ability to regenerate resources is known as our Ecological Footprint. It can be calculated for individuals, organizations, cities, countries, or the entire world. Put simply, it is a calculation that works to ascertain planetary limits, like a spreadsheet of environmental checks and balances.
We all know that nonrenewable resources-such as oil, minerals, and ore-are finite and may someday run out. But if we
deplete renewable resources-say fisheries, forests, and groundwater- faster than the planet can regenerate them, we will run out of these, too. Currently, our demand for the planet's renewable resources exceeds what it can supply by more than 20 percent, according to the Global Footprint Network. Put another way, the planet needs about 14 months to regenerate all of the resources we use in one year. Luckily, the problem isn't insurmountable. By assessing where we're using too much and where we can cut back, we can return to a path of sustainability, where humanity's demands on nature are in balance with nature's capacity to meet those demands.
Our "carbon footprint"-the measure of how much carbon dioxide we emit- makes up about half of the world's overall Ecological Footprint. Carbon dioxide-the main greenhouse gas responsible for global warming- is released any time we combust fossil fuels or make changes in the way we use land; an example would be clearing parts of the Amazonian rain forest and converting them into agricultural plots. The other main anthropogenic greenhouse gases are methane and nitrous oxide, which are released primarily as a result of agriculture and things rotting in landfills.
Quantities of greenhouse gas emissions are often discussed in terms of carbon dioxide for the sake of making easy comparisons. When we say that eating an omnivorous diet creates emissions of 3,000-plus pounds of CO2 per person per year, for example, that figure includes the equivalent amount of methane produced by such a diet.
GLOBAL WARMING: A PRIMER
While many ecological issues-loss of biodiversity, availability of clean water, endangered wildlife, for example-deserve urgent attention, global warming has emerged as the most pressing problem of the day. As such, it warrants some explanation.
Global warming is the increase in the Earth's average temperature due to the buildup in the atmosphere of carbon dioxide and other greenhouse gases. It's true that the atmosphere has always had a natural supply of greenhouse gases that capture heat, which is a good thing, since this is what makes our planet warm enough to inhabit, and not some barren, iced-over wasteland. But too many of these gases present a problem.
Before the industrial revolution, the amount of greenhouse gases released into the atmosphere by humans and nature was roughly in balance with what the Earth could reasonably store, or "sink." For example, a tree absorbs CO2 during its lifetime, but releases it back into the air when it dies and decays. But when humans began burning tremendous amounts of fossil fuels, we created an imbalance of greenhouse gases, which become trapped in the atmosphere, acting like a blanket and heating up the surface of the planet.
Today, the amount of CO2 in the atmosphere is more than 30 percent higher than preindustrial levels. This is almost certainly due to human actions, mainly agriculture, burning fossil fuels, and changes in land use such as deforestation. Today, there's more carbon...
