In 2016, a million plastic bottles were sold every minute across the globe. That’s three million in the time it will take you to read this article. But get yourself a refillable water bottle and you’ll never need to buy a single-use plastic one again. While travelling, this means you can refill whenever you come across a tap or water fountain. If the tap water isn’t drinkable, use the kettle in your room to boil the water or ask your hotel to fill you up with filtered water.
There are plenty of reusable bottles on the market to choose from. Your best bet is a stainless steel one, as it keeps hot drinks hot and cold drinks cold, and doesn’t use more plastic. You could even choose one with a filter, or add your own water purification tablets. If you don’t like the rather distinctive taste of purified water, add some fruit or cucumber to mask the flavour.
Don't forget: when passing through airport security you will need to empty the contents of your bottle. While there should always be a water source on the other side, if there isn’t, you can ask your flight attendant to fill up your bottle for you.
