The Mesoamerican Barrier Reef System is impressive, covering 560 miles from Cancun to Honduras. In Belize, where the reef stretches for a remarkable 186 miles, a company called Blue Ventures has taken a creative and effective approach to conservation. Beginning in January of 2010, Blue Ventures began a project to understand the impact the local coastal communities have on the nearby reef.

When it’s summer, the tourist migration to the Mediterranean’s famed beaches is at its height. However, there’s an older guest who has lived here for the past 95 million years and needs our help: the marine turtle. Saving the marine turtle just may be one of the few things the international community can agree on these days, especially steps taken toward turtle conservation through tourism.

The One Day on Earth project began in 2008, with the vision of uniting the entire world in a single film-related project. The potential for collaboration offered by the internet is something that continues to be explored to this day, but the group behind One Day on Earth set out to achieve something that had never been seen before: a collection of moments, experiences and events from all corners of the globe with a single unifying experience – they all took place on the same day.

Fellow travellers, I have a weakness: I like to shop. Worse, when I travel, my addiction takes over. My Achilles heel is for local souvenirs, the more creative and original, the better.

Barra de Potosí is a small coastal village at the mouth of a lagoon, part of a complex and interdependent system of lagoons, which runs along the coast of the Municipio de Petatlan in Mexico. The people of Barra de Potosí are now confronted by and opposing a development project that they believe will destroy the existing ecosystem. The fight is proving to be a difficult one, and the people can use all the help they can get.

In honour of Earth Day, staff at WHL Group took a moment to think about our planet. Today, we can travel the world in a way that we never could before — virtually, online. Although there is no replacement for seeing the wonders of nature live and in person, digital media such as online video delivers powerful and inspiring messages.

Ilha Grande, Brazil, is a true haven for biological and ecological diversity and much of the credit for the maintenance of its conservation areas is attributed to the relentless work of the Defence Committee of Ilha Grande (CODIG). This non-profit organisation has been fighting for the preservation of Ilha Grande’s ecological integrity and fending off the interests of those seeking capital gains. One project is the eradication of an invasive species of sun coral.
