Earth is a very important part of our lives. Most of us wouldn't think of polluting our bodies, yet we are polluting our planet by misuse and overuse of our natural resources. As responsible individuals we should at least do what we can to help reduce, reuse, and recycle what we can as a first step.
We are not completely to blame; we inherited a polluted Earth, but we can do something to ensure that our children can grow up in a cleaner, safer planet than ourselves.
Don't ever let someone get away with saying "what can I do, I am only one person". Each and every person can do a lot, and you can influence others to do something as well.
It is great to talk about how important the Earth's environment is to you; but it is more important to put words into action. Some actions on our part are very simple and effective such as:
Many grocery stores sell reusable bags (usually 99 cents), buy them and use them.
Turn off the lights when you are not in the room (this is an easy one that is quickly forgotten). Also, unplug your appliances when not in use; even when not in use they can be an "energy sink" just by being plugged in.
Plant a tree or other plants. You might want to think about raising some edible plants (help the environment, save money on food, and feed healthy food to your family - what could be better)
Use refillable bottles for water. Bottled water is a huge culprit to having a clean environment. Stop buying all of those water bottles that fill up our land-fills. If you need special water, buy a water filter.
Reuse what you can, like boxes for mailing and padded envelopes can have several uses in them. Be sure to black out the previous addresses and remove the used stamps.
Plan your trips and combine as many errands into an outing as possible. See if you can carpool to work, or take a bus; or ride a bike to work.
Use natural cleaners whenever possible. It is healthier for the environment as well as for your family.
