Water is really a simple but vital molecule consisting of two
hydrogen and one oxygen atom bonded together. Without water,
life on earth couldn't exist. It covers roughly 80% of
the earth's surface--in rivers, lakes, seas, and oceans. It makes
up 66% of your body. You need about two and a half quarts
of it every day to stay healthy. You could try and get by without
water for about a week, but then you'd keel over, thoroughly dehydrated. Click here

When you've finished chugging down your carbonated beverage
or poured that last drop of milk over your breakfast cereal,
you probably toss the aluminum can or plastic bottle into a
small blue bin, knowing it will be recycled into a new container.
When we recycle containers, be they glass, plastic, or cardboard,
we save resources and energy. But your Coke cans aren't
the only things that are recyclable. Contaminated land, known
as brownfields, is also recycled. Read
how it's done.

But then the Industrial Revolution came along in the 19th Century making the situation a whole lot worse. Since then, carbon dioxide levels have increased nearly 30% and methane concentrations have doubled. Read more...

We need energy to power up our technological world, from laptops
to lamps, cell phones to minivans. But what exactly is energy?
Simply put, it is the ability to do work. Electricity energizes
our gadgets, allowing them to process information, blend a milkshake,
or shine a bright light. Gasoline energizes car engines, pumping
pistons that are lubricated with oil. But where do we get our
energy from? Click here to read
about renewable and non-renewable energy sources.
