We've come a long way, baby

Earth Day is like the environmentalist's Christmas, New Years, Valentine's Day, Mother's Day, and Fourth of July wrapped up in one.

Some may poo-poo Earth Day as having lost its true meaning, but like Charlie Brown, we can always rediscover the heart and soul of the day.

Stripped of the recent commercialism, the whole point of this day has always been to bring attention to our environment and what we need to do to clean it up.

So what better time than Earth Day 2008 to look at how far we've come in the past 12 months, and to think about what we can do to make our planet a cleaner place in the future.

Top five signs we're on the right track

1. Al Gore won the Nobel Peace Prize -- Gore and the Intergovernmental Panel on Climate Change were recognized for their work to spread the word about man-made climate change.
   
   The Nobel Committee made clear the devastating effect global warming will have on human lives and security. For peace in our times, we have to reverse climate change. And thanks to Mr. Gore's work, millions of people are aware of this.


2. Prius sales topped 1 million -- The icon for green driving, Toyota's Prius hybrid car, hit a million cars sold worldwide in June 2007. Over half of those cars are zipping around the U.S.
   
   The Prius is Silicon Valley's car of choice -- as evidenced by the dozens in Yahoo!'s own parking lot (and my own driveway). Other carmakers are jumping on the hybrid bandwagon every model year.


3. Energy Independence and Security Act of 2007 signed into law -- This U.S. legislation, while far from perfect, has huge potential to increase our country's energy efficiency.
   
   It raises standard gas mileage for cars and light trucks (aka SUVs) for the first time ages to 35 mpg by 2020. And this act bans the sale of most incandescent lightbulbs by 2014. We should see more Energy Star-rated appliances too.


4. The Vatican called pollution a sin -- When even the Catholic Church is going green, you know the message has spread. Church official Monsignor Gianfranco Girotti said, "You offend God not only by stealing, blaspheming, or coveting your neighbor's wife, but also by ruining the environment."
   
   Rev. John Wauck from Rome's Pontifical University of the Holy Cross added that protecting the environment is implied in the Bible's Book of Genesis. Pollution is a variation on the mortal sin of gluttony or selfishness.


5. Wal-Mart went green -- Surprisingly, the world's biggest retailer has jumped on the sustainability bandwagon. How much of this is green-washing is debatable, but it's true that the mega-store has made some big eco-friendly efforts.
   
   Wal-Mart sold more than 100 million compact fluorescent light bulbs in 2007, introduced fair-trade certified coffee in April 2008, and buys 10 million pounds of organic cotton annually.
   
   Considering the company expects 90% of American households will shop at its stores this year, I think it's pretty important that Wal-Mart is doing something green.

We're more aware of climate change than ever before. We know something about how our choices in energy use, travel, and shopping affect the planet and our own communities. Let's pat ourselves on the back... then let's get back to work.

Top five things still we need to work on

1. Drive less, carpool more, use public transit -- Gas is climbing to $4 a gallon, so really, who wants to drive more anyway? If the nasty emissions don't make you want to share the ride or get out of the car entirely, the cost should.
   
   Start small by carpooling to work a couple days a week. This really isn't that hard for most people, since statistically our commutes aren't long in distance. It's the time spent sitting in traffic that stretches our workday -- but if your city has carpool lanes, you'll zip to the office and back home easily.


2. Be a conscious consumer, reduce the stuff you buy -- The first step in "reduce, reuse, recycle" is often forgotten, but it's the most important one. The less junk we buy, the less we need to reuse or recycle. We're nipping the problem in the bud.
   
   Do I really need the latest cell phone when I renew my plan? No, even if the company is giving it to me free. The old phone works fine, so why add it to the landfill?
   
   Now personally, I love fashion, but when I feel like having new clothes, I hit the thrift store or look for vintage garb on eBay. At least then I'm not requiring new resources to be used simply for my pleasure, plus I'm keeping stuff out of the garbage.
   
   You don't have to abandon all your possessions and live off the grid, but we can all think a bit more carefully about what we do buy, consider where it comes from, and what we'll do with it after we're finished with it.


3. Avoid toxic plastics -- We're starting to learn that some very common plastics leach toxic chemicals into our bodies, and these chemicals have been linked to cancer, reproductive problems, and other health dangers.
   
   Two biggies to watch out for are Bisphenol A (also known as BPA) and phthalates. BPA is often found in plastic water bottles and baby bottles -- these containers usually have a #7 in the 'chasing arrow' symbol on the bottom. Phthalates are found in PVC and soft vinyl goods plus in personal-care products like shampoos and lotions. Look for any ingredient with "-phthalate" in the name.


4. Conserve water -- According to the United Nations, 41% of the world's population lacks access to clean water. The U.S. southeast was hit by a devastating drought last year, and global climate change will continue to screw with weather patterns.
   
   It's always wise to conserve the water we have, and it's easy too. Fix leaks around the house, install a low-flow showerhead, consider drought-resistant landscaping, heck, even let it mellow if it's yellow. I've heard some famous people even do that.


5. Tell elected officials the environment matters to you (and vote accordingly) -- Our individual actions help a lot. But to make the biggest impact possible, we need our government to act.
   
   Legislation ensures that corporations don't pollute the skies and oceans or use up all our natural resources. Our government can influence other countries to clean up their acts too.
   
   So remind your representatives at the state and federal level that you care about our environment and want them to act with the planet in mind. And in November, when you have a chance to vote for a new president, consider the candidates' views on climate change too.
