Straws have become a huge problem in ocean contamination--in fact, they're one of the most common pieces of trash picked up on beaches. Eliminating straw use is easy and straightforward--if you order a drink that comes with a straw, just tell the waiter, barista, or worker that you don't need one. You can also invest in reusable straws made of glass or stainless steel. Instead of ordering coffee in the usual plastic cups and tops, bring your own to-go mug or thermos and ask the cashier to fill it. Insulated tumblers can also keep your beverage hot or cold much longer. Even paper coffee cups are often coated with a plastic resin, so skip these as well in favor of a reusable vessel. Rather than use the dry-cleaner's single-use plastic bags, bring your own fabric garment bag to hold your clothing. You can purchase recycled dry-cleaner bags made of a more durable, longer-lasting plastic online. Bring fewer clothes to the dry-cleaner's to reduce your bag use as well. Although gum was originally made from natural materials such as sap and rubber, manufacturers now use a type of plastic instead. So instead of chewing and throwing away plastic, find a natural brand of gum or just use mints instead.

Summary:
Skip the plastic straws. Bring a reusable tumbler or to-go mug when you order coffee. Carry your dry-cleaning in a reusable bag. Stop chewing gum.
