For pirate crew, your top doesn't need to be as fancy as that which would be worn by the pirate captain or long-term senior pirate crew. A t-shirt will serve adequately. A larger shirt is best to give the idea of rugged sloppiness, which all good pirates attempt to get across. You've been at sea for months. Though you don't want to pretend you have scurvy, make it seem you're a little worse for the wear. Cut areas of the t-shirt to give an impression of ruggedness: Cut off the ends of the sleeves in a jagged fashion. Cut the bottom of the t-shirt off. Pirates don't need hems. Cut off the neckline of the t-shirt. $10 says Hanes was not around in the era of your pirate. Also paint lines around the sleeves. These don't need to be perfectthe more homemade they look, the better. Allow the paint to dry, then flip the t-shirt over and paint the back the same way.

Avoid single-serve or individually wrapped items. Shop at stores that have bulk dispensers for grains, nuts, dried fruits, and snacks. Bring your own plastic bag or container to put the bulk food in. And try to buy bulk sizes of food or sanitary products, which saves on packaging. When buying produce at the grocery store, avoid packing the product in an extra plastic bag if it isn't necessary. Vegetables such as potatoes, onions, peppers, tomatoes, beets; and fruits such as bananas, apples, plums, and melons shouldn't require an extra bag. Instead of buying canned soup or pasta sauce, read up in a cookbook how to prepare them at home. Practice "precycling" by only buying products whose materials can be recycled. Take durable canvas or synthetic-fiber bags, a backpack, or a basket with you to the store, enough to hold whatever you plan on buying. These can usually be bought at the stores themselves. A heavy-duty plastic bag that you use multiple times can serve the purpose almost as well. Disposables contribute large amounts of waste to our environment. They include things like plastic forks, knives, plates, and cups. They also include things like diapers and razor blades. Instead of buying items that you'll throw away after using them, buy items that you can use again and again. For example: Instead of using disposable diapers, try cloth diapers or nappies. You will have to clean them more often, but you'll reduce waste. Get a razor with replaceable blades rather than a disposable razor. You'll still have to throw the old blades away, but you'll save the plastic handle. For picnics, serve with re-usable plastic or wooden plates, cups, and utensils instead of disposable paper or plastic ones. Turn off or unplug any electrical appliances that aren't being used, such as the TV, radio, stereo, computer, lights, or chargers for cellphones or mp3 players. Try to wash clothes by hand, and dry them outside as much as possible. And if you purchase appliances, such as dishwashers, washing machines, and dryers, choose ones that are rated with the Energy Star classification. Replace all incandescent lightbulbs with Energy-Star-rated compact fluorescent lightbulbs (CFLs), which can save you $6 in energy costs per year. Try towel drying your hair instead of blow-drying it. If it is cold inside your residence, just put on a jacket or sweater instead of turning up the heat. Try to reduce your shower time to between 5 and 10 minutes. Turn off the water when shampooing or scrubbing. Take fewer baths as well, since they can consume more water than a short shower. When you brush your teeth, turn off the faucet between soaking and rinsing the brush. If you're receiving junk mail, call the sending company's 800 number, usually found on the offer or order page, and ask to be removed from their mailing list. Request electronic bill instead of paper ones for all your utilities, member dues, and other periodical payments. You can choose this when signing up for an account. If you are already receiving paper bills, it is not too late to change. Access your account online or by phone, and see if you can switch to electronic bills instead. Try to walk, bike, or take public transit to school or work. If possible, invest in an electric or hybrid vehicle--these options are more fuel-efficient and emit less carbon into the atmosphere. Organize carpools with your neighbors or co-workers to reduce fossil fuel use. Choosing a residence as close as possible to your place of work will reduce both your commute time and energy consumption. Escalators and elevators are convenient, but sometimes they are not necessary, especially if you only have to travel 1 or 2 floors. Not only will taking the stairs save electricity, but you'll also get some exercise in. You also won't have to wait in line. Escalators and elevators cost money to run. By taking the stairs, you may see lower prices (if you're at a shopping center) or a higher salary (if you're at an office building). There are instances where taking escalators or elevators may be necessary, such as if you have an injury, a bad knee, or need to get to the 24th floor.
