Dakuwaqa's Garden - Underwater footage from Fiji & TongaLast Updated on 2013-12-03 11:23:34Underwater footage shot whilst scuba diving in the Fiji islands and Tonga. Featuring colorful coral reefs, huge schools of tropical fish, sharks, humpback whales, underwater caves, scuba divers and much more marine life from the south Pacific.

The coral reefs of the south Pacific are alive with a huge variety of tropical fish and marine critters. A great way to explore them is to scuba dive with the Nai'a liveaboard based in Fiji. I was working as the Nai'a's video pro when I shot this footage. See http://www.naia.com.fj/

Food Choices Are A Key Strategy for Sustainable TourismLast Updated on 2013-11-25 12:44:35Most people agree that good tasting food is part of what makes our travels more enjoyable. Unfortunately, the food served at tourism resorts is often not very sustainable.
Our food choices do impact tourism in several ways including the climate change impacts, higher energy costs, soil erosion and loss of agricultural land, and marine environment pollution from fertilizers.
It is estimated that global food production contributes between 14 and and 22% of total CO2 the world produces every year.
Food production is one of the greatest sources of greenhouse gas emissions including:
emissions from animals
transport of food
deforestation to develop cropland
The U.N. Food & Agriculture Organization reports that our diets, especially meats, may cause more CO2 than industry or transportation.
Higher energy costs can make tourism operations less profitable. As... More »
Pacific Ocean warming faster than it has in 10,000 years, study findsLast Updated on 2013-11-05 07:00:32By Tony Barboza
Los Angeles Times
LOS ANGELES — Scientists have struggled to explain a recent slowdown in the rise of global surface temperatures while skeptics have seized on the 15-year lull to cast doubt on the science of climate change.
A new study offers one explanation of where much of the heat trapped by greenhouse gas emissions is going: the ocean.
Scientists found that parts of the Pacific Ocean are absorbing heat faster than they have over the past 10,000 years. The results, published this past week in the journal Science, suggest seawater is capturing far more energy than previously thought, for now sparing land-dwellers some of the worst effects of climate change.
The ocean’s heat content, which has been measured since the 1960s, accounts for about 90 percent of the earth’s warming, the study says, making it a more reliable indicator of climate change... More »
Ocean Warming Faster Now Than in 10,000 YearsLast Updated on 2013-11-02 10:48:37Pacific Ocean waters warmed 15 times faster in the last six decades than they did over the last ten millennia.
Published October 31, 2013
The ocean depths may store more heat from global warming than suspected, suggests a 10,000-year record of past ocean temperatures measured in Indonesian seafloor cores.
At the same time, since 1950 Pacific Ocean waters have been warming at a rate 15 times faster than the rest of the seafloor, as reported in the journal Science.
"Under normal, natural conditions the oceans are a buffer for temperature changes in the atmosphere," says study lead author Yair Rosenthal of Rutgers University in New Jersey. "But right now, we are completely out of equilibrium." (See "What is Global Warming?")

Plastics Contaminating Lakes, GloballyLast Updated on 2013-10-18 21:57:37
Toxic plastic pollution is filling up the Great Lakes, the European lakes and even the subalpine lakes in Europe's famed Alps. This insidious byproduct of petroleum has infiltrated marine food webs and humans are indeed in harms way.
It wasn't until World War II that polyethylene (plastic single-use disposable bags, dispensable bottles), propylene (bottle caps, fishing gear) and polystyrene (take-away food containers) were invented, and by the late 1960s being mass-produced. By 1979, the production of plastics in the U.S. eclipsed that of steel. Today, globally, humans produce 280 million metric tons of plastic annually.
Plastics are long chains of monomer hydrocarbon molecules, and one of the principle ingredients of all plastics is crude oil. How much? Four percent of the entire world supply, or about 3.4 million barrels of oil, are used to make them each day.
