Our everyday lives are essentially killing the environment. There are certainly important changes that need to be made at every level--statewide, nationwide, and even worldwide--that can help preserve the Earth. That doesn't mean, though, that there's nothing that can be done on an individual level.

We spoke to eight of the country's leading environmentalists and asked them this question: Their individual answer varied, but the point they truly wanted to stress did not: One person can make a difference.

The other common idea was that they had a difficult time limiting it to only one tip. Matt Peterson, president of Global Green USA, recommended that, in the long run, we rebuild our buildings so that they are green.

Dr. Brent Blackwelder, president of Friends of the Earth, emphasizes the importance of the state and federal tax code on the energy choices we make, and feels that this is a widely overlooked（被忽視的） issue. " One example cited is the "gas-guzzler（耗油量極大的汽車） tax," as it is often referred to. This tax loophole（漏洞）has encouraged automakers to focus their production and advertising efforts on the products that end up being the biggest gas-guzzlers and polluters.

Equally the carbon footprint, measured in carbon dioxide units, calculates the impact human beings have on the environment in terms of the amount of greenhouses gases produced.

Both our direct emissions（排放） of carbon dioxide, like the burning of fossil fuels and the indirect emissions of carbon dioxide as a result of the manufacture and breakdown of everyday products are calculated into the carbon footprint measurement. Commonplace activities like eating red meat and drinking bottled water are slowly but surely contributing to the devastation of our environment.

So take our experts' tips into consideration. This Earth Day, give Mother Nature the day off. Take public transportation, turn out your lights, and try not to print every one of your e-mails. It's the little things that really can make a difference.
