As the sport of surfing grows, so does its environmental impact. Surfing equipment made of non-biodegradable materials such as synthetic resin surfboards, neoprene wetsuits and petroleum-based surf wax are just some of the products used by surfers that can have a negative ecological footprint. Environmentally conscious surfing companies such as Envirosurfer are attempting to address some of the ecological issues with surfing products and offer green alternatives. For example, wooden or epoxy boards, as well as surfboards made with bamboo-based resin, last longer, are less wasteful and less toxic than typical polyurethane boards. Other tips include using thinner and more…

Are their tiny nanotech machines in your sun block? Recent headlines about nanotech being in sunscreen seem a bit misleading upon closer inspection. These are not tiny machines or circuits buzzing around that white cream you slather on to prevent sunburn and skin cancer. The American Heritage Dictionary defines nanotechnology as such: The science and technology of building electronic circuits and devices from single atoms and molecules. Nanoparticles are measured between 1 and 2,500 nanometers, depending on their classification. One nanometer is one billionth of a meter, so even the largest of nanoparticles is pretty small. The fuss is about…

Researchers from Kings College London are studying the symbiotic relationship between coral and algae living in Australia’s Great Barrier Reef. They found that in order to survive in strong sunlight, coral produces compounds that act as a natural sunscreen. Scientists hope to use genetic engineering to recreate the compounds in a laboratory back in the UK and eventually develop a sunscreen in pill form. Since the compound is already present in the food chain in the coral reefs – small fish ingest it while feeding off the coral, larger fish eat them and so on – the scientists hope it…
