    Author Elizabeth Becker says we have a responsibility to respect the places we visit. Some basic rules still hold, such as not travelling at busy times and taking fewer trips but making them longer. The best and easiest way to be a responsible traveler is to use common sense and go local.

    Respect traditions. Read about the culture and traditions of the places you visit. Understand the local culture and customs to avoid making any mistakes or upsetting the local people. For example, dress properly when you visit temples and don’t eat or talk loudly in religious(宗教的)sites. It’s also important to respect the local environment. If you visit a beach, leave seashells where you find them and try not to catch fish while swimming.

    Learn the language. Nobody expects you to become fluent, but try to learn some basic phrases such as “please” and “thank you”. You’ll be amazed at how much nicer and more helpful people will be if they know you’re making an effort to get involved with their culture.

    Spend local. Stay away from international hotels and restaurants run by foreigners. By using local guides, buying local products and staying in family run hotels, you’re not only giving back to the community, but you also get a real sense of the country you’re staying in and the people who live there.

    Bargain fairly. Always be polite when you try to get a lower price. Sometimes goods at a local market can seem overpriced. Nobody likes to be cheated and it may be fun to bargain, but remember that for the local people bargaining it may not be a game. For some of them, their business is their only source of income. So try not to be too rude when bargaining.

    Don’t litter. In some countries, getting rid of waste is a big problem, so don’t throw rubbish on the ground. Doing so is harmful to the environment and unpleasant for others. Hold on to your rubbish until you find a bin.

    Save water. Even in some of the most developed countries, water shortages are a reality. Tourists who take 10-minute showers and leave the taps running aren’t making things any better.
