    According to the International Ecotourism Society, eco-travel is “responsible travel to natural areas that protects the environment, maintains the well-beings and involves education”. Eco-travel is on the rise, as more and more people become conscious about their carbon footprint.

Expert from Boundless Journeys, Matt Holmes, who works-on travel experiences towards conserving areas said, “As scientists and non-scientists learn more about how we human beings are impacting the planet, I think. more people want to do what they can while still exploring the world. Our guests are definitely interested in that aspect of our journeys. Travelers can farm their own food in Italy, managing their use of water and using solar or wind power. They can also visit n family-run camp that cares for retired logging elephants in Myanmar, know a park entry fee goes to a conservation organization in Costa Rica, employ and train members of the local community or partner with a protection group. There are lots of options for seeking out greener holiday.”

Most people believe that eco-travel is expensive and it is true. Matt explained “Anti-poaching patrols (巡逻) need to be paid, solar energy equipment costs a lot to install, building with environmentally friendly, materials is more expensive and so on. The extra cost is necessary, as you re paying to minimize your footprint and protect the places you visit, which is exactly what eco-travel is about. The financial success and sustainability (可持续性) of an eco- focused operation doesn’t come from thin air.” The industry is trying to make eco-travel affordable and make it accessible to the common people.
