The Earthwave Global Surf Challenge is an initiative created by the Cape Town based Kahuna Surfing Academy that showcases the global nature of the surfing community, highlights their environmental concerns and issues a "call to action" on how we can reduce our impact on climate change.

By staging attempts on the Guinness World Record for the ‘most surfers riding one wave simultaneously’ on beaches worldwide on the first Sunday in September annually, Earthwave provides a platform for surfers of every age and ability to participate in an enjoyable group activity.

Leveraging the newsworthiness of world record attempts, Earthwave seeks to raise awareness of the threat of Global Warming and its effects on our oceans and waves while mobilizing the trendsetting surfing fraternity through practical advice on how to become part of the solution to the most devastating problem ever faced by mankind.

Our home — Earth — is in danger. What is at risk of being destroyed is not the planet itself, but the conditions that have made it hospitable for human beings. AL GORE (NY Times 1 July 2007)

Keep your water heater down to 130F (54C). This is hot enough to kill bacteria and still save energy.
