"Never leave a local place without a meal with a local person."

That travel advice came straight from Bruce Poon Tip, founder of G Adventures and an expert in sustainable tourism, as he chatted with The Huffington Post Alberta during a recent visit to Calgary.

Canadian travellers are looking to extend their green lifestyles while travelling, says Poon Tip, not wanting to abandon organic food or caring about the environment when around the globe.

"There's a tipping point where people want to choose their holidays the same way they live their life," says Poon Tip.

The tourism industry is worth $6 trillion today and generates 9.1 per cent of the world's GDP. Travel has doubled in the past ten years and some destinations can expect up to five times more visitors.

"Certain areas are going to explode," Poon Tip says.

  • Eat With A Local

    "Never leave a local place without a meal with a local person," says Tip. Food connects us across the globe, share some with a local.

  • Ask Questions

    Ask questions about which companies benefits from your purchases. Ask who owns the company that you're buying from and try to find local operators.

  • Say No To All-Inclusives

    Try not to choose all inclusive vacations.

  • A Word On Discounts

    On addressing the attraction of discounts, Tip says travelling in those prices squeezes local operators. Tour companies are still making record profits by "controlling your movements." You can still take the trip, says Tip, just don't take it all-inclusive.

  • Get Off The Resort

    Get off the resort you're staying at to "spread the wealth." It's always really cheap and you get to really explore a destination. Ask a local taxi driver for a tour for $25, not the one offered by the resort.

  • Take Photos

    Always travel with photos of the place you've come from, even if they're cliche postcards of your country. It shows people where you came from and lets them engage with your culture.

  • Be Vocal

    Share your adventure with people when you return from a trip. Be vocal, tell people what you experienced and about your travels.

Sustainable tourism began when people started looking at the environments and cultural heritage of the places they were visiting, Poon Tip says. Travellers, he added, are increasingly concerned about preserving destinations for future generations.

Many islands in the Caribbean, for example, have seen local resources gobbled up by tourists.

"Locals can't enjoy the beach with their family," Poon Tip says.

Kids don't go to school the day a cruise ship comes in, as they're too busy pitching products to tourists who will spend up to $100,000 in a few hours, Poon Tip says.

According to a United Nations Environment Programme report in 2008, only $5 of every $100 spent in a growing economy stays in the country.

Many cruise ship companies own restaurants, shops and other activities on islands, leaving few dollars for local economies. Cruises often organize tours that take travellers to those very businesses, which helps them offset cheaper deals offered on the ships themselves.

"The actual issue that we have is education of the consumers," says Poon Tip. People need to be "consuming tourism as carefully as they choose the stuff in their homes."

There are always options beyond the ones that cruises offer, says Poon Tip, and many travelers never actually enter the country they're visiting.

"The consumer has to create the demand and ultimately all operations will start to create these," says Poon Tip.

Venturing out of resorts and eating at local restaurants create a human-to-human experience with people around the world, he says.

"Suddenly a whole network of people have benefited from your visit.'
