Summarize this article in one sentence.
Around the house, a lot of paper is wasted every year on things like paper towels and napkins. And if you're using lots of paper products for cleaning, drying, and wiping your nose, you can save plenty of trees by switching to reusable versions.  To replace paper towels in the kitchen and bathroom, use tea towels to dry dishes, old rags to clean, and sponges to wipe up spills. To replace facial tissues, invest in a few handkerchiefs that can be washed and reused. To replace napkins at the dinner table, purchase cloth napkins instead, which can be washed and reused as well. Paper plates and dishes may be convenient, but they aren't good for the environment. Most paper plates just end up in the trash, meaning the paper isn't even recycled properly. When you have a party or any time the paper plates come out, ask to use the real dinnerware instead. If your family likes to go on picnics or camping trips, invest in reusable plastic dinnerware. You can get plates, bowls, cups, and utensils that are durable, unbreakable, reusable, and not made from paper. There are times when it’s simply not possible to avoid paper-like products. Luckily, there are tree-free paper products available that are made from alternative plant sources, and many of these have a lower impact on the environment.  Hemp is a versatile plant that grows much faster than a tree and produces more fiber. Hemp can be turned into fabric, writing paper, greeting cards, envelopes, and other paper products. Bamboo is another fast-growing species of plant that can be used for alternative paper products. You can find bamboo bathroom tissue, paper, towels, and even disposable dinnerware. Disposable paper cups from cafes and restaurants are another way that lots of paper is wasted every year. Like paper plates, many paper cups end up in the trash because they are not recyclable (they are usually coated with plastic; in the case of uncoated paper cups, they are soiled with liquid). Any time you go to a restaurant or cafe for a takeout drink, take a reusable coffee mug or thermos with you for coffee, hot chocolate, or other warm beverages. Many grocery stores provide paper bags to pack groceries. You can help your family save paper by investing in reusable grocery bags. Similarly, if your lunches are normally packed in paper bags, ask about switching to a reusable lunch bag instead. If your family is hesitant about switching, ask them to consider how much money they spend on paper bags and grocery bags every year. Then, compare that to the one-time cost of reusable bags. Lots of people like to send greeting cards for birthdays, holidays, and other events, and this leads to plenty of paper waste. Not only is the card itself paper, but it’s also sent in a paper envelope. Instead of sending paper greeting cards to all your friends and family in the mail, send electronic greeting cards for future celebrations.  There are lots of e-card services out there that allow you to personalize designs, messages, and graphics to suit your taste and the type of celebration. E-cards are also great for sending out invitations to parties, weddings, and other events. Books are great resources for school and work projects, and they're great to read as a leisure activity. But printed books are still made with paper, so you can save paper by using public versions of books that are available at the library, or by reading electronic copies instead. Buying used books is also a good idea, because you're reusing something that’s already been printed. School and work notebooks are a great way to keep track of things you're supposed to learn and projects you're working on, but you can save paper by keeping electronic notes instead. That way, you don’t have to rely on paper notebooks, and you can always have your notes saved to your computer. If you're in school, ask your teacher if it’s OK that you take notes on a computer or laptop instead of in a notebook.

Use reusable cloths instead of paper products. Use real dinnerware instead of paper. Use paper from other plant sources. Bring your own thermos or reusable mug to cafes. Use reusable grocery and lunch bags. Send e-cards. Read e-books or library books. Use computers instead of notebooks for school and work.
