We’ve all visited neglected, underfunded and high-traffic tourist parks where wild and endangered animals have become almost tame. Sites such as these, where regulations are inadequately enforced, are unfortunately far too common. On the sunny flip side of this is well-planned ecotourism, the kind that helps conserve many outdoor and wilderness spaces that may be a last hope for endangered species.

What is ecotourism? To most people, it’s a confusing and only vaguely familiar term. Some ask “Does ecotourism mean staying in ecolodges?” Yes, it does, but that’s not all. Ecotourism is an approach to travel that embraces all the principles of responsible tourism, not just choice of accommodation. Still, if you’re new to eco-travel, ecolodges are a great place to start.

In the beautiful region of Wayanad in Kerala, India, where dense jungle carpets the rolling mountains in the Western Ghats, lies a magical hidden gem. The quiet village of Thrikkaipetta in the heart of this breathtaking region is a beacon for community spirit and an inspiration for ethical tourism.

Since the very first Earth Day on April 22, 1970, over 20 million Americans from all walks of life have contributed to major environmental accomplishments. For 2012, the Earth Day Network is again hosting “A Billion Acts of Green®” with the ambitious goal of registering another one billion environmentally friendly actions.

In honour of Earth Day – scheduled this year for Sunday April 22 – and our focus this month on ecotourism, we’re thinking about our planet. We’re thinking about the human activities that have the most harmful impact on it, especially the one we love most – travel. We’re compelled to ask: What is tourism in its worst form, environmentally? Even in its best form, can the cost to the earth of tourism ever really be offset?

Laos was once majestically known as Lane Xang – Land of a Million Elephants. Today, however, the outlook for the Asian elephant population in Laos is bleak. Only 1,000 remain and their numbers are steadily decreasing. An estimated 560 still work in logging, the industry that is primarily responsible for their slow demise. Fortunately, tourism is offering one positive solution.
