Today is Earth Day. Held around the globe, Earth Day reminds us that we all need to increase our awareness of how we treat this little blue planet, third from the sun. It's the only one we have. In recognition of this annual event, here are some "green" movies that not only showcase our planet, but give us food for thought.

Have you ever given any thought to the process that makes the water you drink from your tap drinkable? No? You're not alone. Most of us don't; we simply expect that when we turn on the tap in our kitchens and bathrooms the water will be clean and will pose no harm to our health.

We all go into grocery stores and shopping malls every day laden with gifts, purchases and necessities usually placed in plastic bags. We take our items home, put the plastic bags away and reuse them for a later time. We don’t think of them any more beyond that.

With gas prices high, and most of the population convinced that global warming is a real concern with a real human cause, it began to look like the world --and America in particular-- was ready to make a change.

We all know that recycling is an important part of taking care of the environment. It preserves resources, saves energy, and keeps garbage out of our seas and landfills. But recycling isn't necessarily a smooth process... in fact, some reports have shown that the effort you put into recycling occasionally goes to waste, and that some of what you toss in the recycling bin ends up in landfills on the other side of the world.

It’s the time of year that we clean up our patios and gardens, put away our lawn furniture into storage and clean up our yards.

As time passes and pollution becomes a larger and larger worldwide concern, we are all becoming more aware of the need to wean ourselves off our dependency on fossil fuels.

Six considerations for lessening your environmental footprint.

Making some 'green' changes may seem daunting at first, but before you know it, going green will become second nature.

As the price of gas rises along with the average temperature of the Earth according to some scientists, all of us are becoming more and more aware of the impact our vehicles have on the environment.
