Let's do something to reduce CO2 emissions

A few days ago I came across a new website named Yahoo! Green created by Yahoo and I noticed that there's quite a number of simple things we can do to reduce CO₂ emissions. Let me copy some of the easy ones here (well, I mean, easy to me):

• Turn your heater thermostat down 2 degrees in winter and up 2 degrees in the summer (Actually, I use a window fan like this one unless it's freaking hot)
  

• Drive less aggressively -- don't accelerate and brake rapidly (Quite a number of my guy friends drive very aggressively. I really don't think the few minutes saved by this driving style are worth the increased danger, not to mention the extra gallons of gas used)
  

• Keep the tires on your car adequately inflated. Check them monthly (Whenever you do an oil change for your car, ask the mechanic to check the tires' pressure too)
  

• Turn off the car instead of idling (Especially when the girl you're dating says that she'll be ready in 1 minute. You know it's 15 minutes+)
  

• Recycle all steel ("tin") cans, aluminum cans, and glass containers (Buy a big trash can to store all the cans and there should be some recycling centers near your home. If you live around Alhambra there's an automatic recycling machine in the 168 Chinese supermarket parking lot near the intersection of Valley Blvd and New Ave. You can bring the receipt to that Sav-On in the same plaza to get the $$) (Oh, you can also find the locations of the recycling centers at BottlersAndCans.com)
  

• Bring your own canvas bags to the store instead of using plastic or paper (Actually, I'm not sure if I can do this one since the plastic bags from supermarkets are my major source of trash bags. However, I'm thinking maybe we can bring lunch boxes to restaurants to pack the leftover instead of using the foam carryout boxes provided by the restaurants. This saves the restaurant's money and the environment, a win-win!)
  

• Buy products in the largest size you can use to avoid excess packaging (If you're a Costco member, you're already doing this. This one is easy as long as the products won't expire soon, such as vegetables)
  

• Turn out the light when you leave the room (Call me a freak or something, but I've a habit of turning off all the electronic appliances in my room even though I just leave the room for a few minutes. This saves you money and the environment, again a win-win!)
  

• Shut down your computer and peripherals each night (Come on, you're not running a server, why leave it on all night long? Don't you think that the noise produced by the hard drive is annoying?)
  

• Run the clothes washer with only full loads (I've been doing this all the time; the washing and drying machines at my apartment cost me $1.25 and $1.00 for each load. It's such a rip off..)
  

• Wash your clothes in cold water (I actually heard that it's better for most kind of clothes if you wash them in cold water. Again a win-win!)
  

• Take showers instead of baths (Anyone of you takes baths?? I'll never take bath since my bathtub is just not so clean)
  

• Take shorter showers (Hmmm this one is kind of difficult since a hot shower is very relaxing. I'll try though haha)
  

• Get off junk mail lists (Haven't tried the actions from this page yet but it looks reasonable to me. Yes, it's annoying to go through all those steps to stop the paper junk mail, but it's a one-time effort. Oh, and there's a number you can call to stop those pre-approved credit card offer letters)

If you are hungry for more actions you can do to save the environment, make up your own plan on Yahoo! Green. There've more tips over there.

Seriously, if we continue destroying the Earth the way we're doing now, will there still be any human being in, say, 2500 A.D.? I really doubt it... (O___O )
