Going somewhere without making it worse

Tourism is one of the largest industries on Earth and it is neither inherently good nor inherently bad for the places it lands on. It funds national parks and it drains aquifers. It keeps languages and crafts economically alive and it prices families out of their own neighbourhoods.

Which of those happens depends substantially on decisions individual travellers make, and a small number of those decisions carry most of the weight. Here is where the leverage actually is.

1. Go at a different time of year

This is the highest-impact and lowest-effort change available. Peak-season tourism concentrates enormous pressure into six or eight weeks: on water supply, on waste systems, on housing, on transport, on the people who work in it. The same number of visitors spread across the year is a manageable economy; compressed into August it is a crisis with a queue.

Travelling in shoulder season costs you less, gets you more, and measurably helps. There is no trade-off to weigh.

2. Stay fewer nights in more places, or more nights in fewer

Two things are true at once. Overnight visitors spend far more locally than day visitors, so cruise-style day stops extract the least and impose the most. And short-let apartments in historic centres remove long-term housing stock, which is why Barcelona, Lisbon, Amsterdam and Kyoto have all had to legislate.

The practical version: stay longer in each place, and stay in a family-run guesthouse, a small hotel or a licensed room rather than an apartment that used to be somebody's home.

3. Make the money land locally

The share of tourist spending that stays in the destination varies enormously. All-inclusive resorts owned abroad, booked through a foreign platform, staffed on imported supply chains, keep very little in the country. A guesthouse, a local guide, a market stall and a family restaurant keep almost all of it.

• Hire local guides. They know where the water is, which track is passable, and what you are looking at - and it is one of the few good jobs in many remote regions.
• Eat where the food is bought locally. Markets, family restaurants, street stalls.
• Buy things made where you are, from the person who made them. Ask what it is and how long it took. In Guna Yala a hand-stitched mola takes weeks; the price will feel like theft on your side.
• Pay the local price without haggling it to the floor. The negotiation is often part of the culture; grinding a stallholder down over the equivalent of a coffee is not.
• Tip according to local norms, and remember that they are norms - expected in the United States, unusual in Japan, rounded up in much of Europe.

4. The animal question, answered simply

This is where well-meaning travellers most often do harm, because the marketing is designed to be reassuring. A workable rule: if you can touch it, ride it, hold it, swim with it on demand or watch it perform, it is almost certainly not a sanctuary.

Wild animals do not tolerate close human contact without either training that involves suffering, sedation, or removal from the wild as infants. Elephant rides, tiger selfies, dolphin shows, photo props and "orphanages" that let you cuddle predators all sit in that category regardless of the word on the sign.

What good looks like: animals at a distance, in their own habitat, on their own terms, with a limit on group size and time. Gorilla trekking in Bwindi keeps you seven metres away and an hour long. Rangers in Komodo carry a stick and you walk around the dragon. The manta rays in Kona arrive because the plankton does, not because anyone fed them.

5. Water, waste and the things that are actually scarce

In much of the world the hotel you are staying in uses more water per guest per day than a local household does. On islands and in deserts, that water is desalinated or trucked in.

• Reuse towels, take shorter showers, and do not use a pool in a place with water restrictions.
• Carry a refillable bottle, and a filter where the tap water is a question. Plastic bottles in places with no waste infrastructure end up in the same three places every time.
• Take your batteries, wipes and packaging out with you if the destination cannot process them. Rwanda outlawed non-biodegradable plastic bags in 2008 and confiscates them from arriving travellers; that is a model, not an inconvenience.
• Reef-safe sunscreen matters where there is reef. Palau restricted reef-toxic ingredients in 2020.

6. Fly less, stay longer

Flying is the largest single component of most trips' carbon footprint, and no amount of towel reuse offsets a short-haul weekend. The two changes that count are taking fewer, longer trips, and choosing rail where rail is competitive - which, city centre to city centre, is nearly everywhere under about six hours.

Direct flights beat connections, because take-off and climb dominate fuel use. Economy class has a fraction of the per-passenger footprint of business, simply because of floor area. Offsets are better than nothing and considerably worse than not flying; treat them as a donation, not a licence.

7. Behave like a guest, because you are one

Most of this is not complicated. Learn ten words. Dress as the place expects at religious sites. Ask before photographing. Find out what the rules are - Nyepi in Bali means the airport closes and nobody goes outside for 24 hours, and that applies to you too. Do not climb on things that are sacred, and do not take the lava home, which in Hawaii is considered both disrespectful and unlucky.

The best short version of this belongs to the outdoors: leave it better than you found it. Take nothing but pictures, leave nothing but footprints.

What not to worry about

Some things get moralised far beyond their impact. Whether you use a paper or digital ticket is irrelevant. Whether you buy a souvenir is irrelevant. Whether you visit a country at all is usually the wrong question - the people who lose most when tourism collapses are the people who depend on it, and staying home is rarely the ethical choice it feels like.

The decisions that matter are: when you go, how long you stay, how you get there, where you sleep, who you pay, and whether you touch the wildlife. Get those six right and you are doing more than almost anyone else on the plane.
