Recycle! I can't emphasize that enough. Some people don't know this, but you can recycle more than just cardboard, paper, plastic bottles, and aluminum cans! Most shampoo bottles, conditioner bottles, body wash bottles, laundry detergent bottles, dish washing liquid bottles, etc. are all recyclable! Anything that seems like it's plastic, check the bottom to see what number is inside the triangle to see if your town accepts that number! And don't forget all types of glass are also recyclable. You can also bring your old microwave, refrigerator, dryer, oven, air conditioner, or hot water tank to your local recycling facility. Fluorescent bulbs and other mercury containing items, used oil, lead acid batteries, antifreeze, oil filters, scrap metal, propane tanks, and yard waste (leaves, branches, grass) can also be brought to your local facility to recycle. If you are unsure if something is recyclable, call your local recycling facility! Don't just throw it out without checking first. Also, I don't know about other towns, but the recycling facility in my town takes latex paint, oil-based paint, stains and polyurethanes, as long as it's at least 1/2 full, the original label is on the can, and the product is usable, one pint up to one gallon is accepted. Residents can go the recycling center and pick up paint. That is a great way to recycle paint, etc. Sometimes you buy paint and when you try it out you realize you don't like it, but someone else might like it, so please recycle your paint, and next time you need paint or stain, check your recycling center before you go the home improvement store.
Turn off that TV! Many people leave their TVs and computers on when they're not even using them! Turn off the TV when you're not watching it, and at least put your computer in hibernate or sleep mode to save electricity when you're not using it.
Turn off the lights! Some people leave their lights on while they're out, or even while they're sleeping. Make sure ALL lights are turned off, even the little table lamp. If you have a light outside your front door for safety, get a motion sensored light that only turns on when it senses motion. Those are actually safer because if someone comes to the door, the light turns on and the person thinks you are up and have turned the light on.
Reuse your bags at the grocery store! If you want to buy a few reusable bags for your grocery shopping, that's great. If you're not into that and just can't see life without a ton of plastic grocery bags for your $300/week grocery shopping trips, don't throw them out! Reuse them for other things, like picking up your dog's poo, or returning something to the store. Store the plastic bags in your pantry, or bring them back to the store to recycle them if you know you'll never use them. Most supermarkets have an area where you can recycle your plastic bags. But I find that it's always good to have at least a few stored for whatever I might need them for.
Pay your bills online! Set up automatic payments for your bills online. It's easier than you might think. If you're really not computer saavy, a customer service representative can help you over the phone. Request that the paper bills no longer be mailed to you. Instead, have them emailed to you.
Online banking! Sign up for online banking and ask that paper statements no longer be mailed to you, but emailed instead.
Oh and I need to add: Quit smoking! Cigarette smoke, pipe smoke, cigar smoke, etc. are all horrible for the environment and for your health and others around you! On a personal level, I can't tell you how annoying it is when I am driving with the windows down and get stuck at a red light next to someone smoking a cigarette in their car with their windows down. Cigarette smoke gives me a headache instantly. I want to be able to drive with my windows down without being poisoned! If you don't have respect for your own self, please at least have respect for others around you and don't smoke.
