Even though this plant is native to the North America and Eurasia but the distribution is wide spread now and you can also find it in The Great Barrier Reef. World-first research on the Great Barrier Reef has shown how ‘weed-like’ algae will kill vital coral because of increased carbon dioxide concentrations in the atmosphere. Surveys of the World Heritage-listed reef, already at risk from global warming, found that more than 40 percent of areas closest to shore were … It is also a vital resource for almost 500 million people. Farming seaweed in targeted locations across the Great Barrier Reef could be the solution to safely soaking up excessive nitrogen that is damaging coastal ecosystems. World-first research on the Great Barrier Reef has shown how ‘weed-like’ algae will kill vital coral because of increased carbon dioxide concentrations in the atmosphere. The Great Barrier Reef just experienced its third mass bleaching event in five years and, this time, nearly 25 percent of The Great Barrier Reef is severely bleached. Clownfish The clownfish is a species of fish. Red and brown algae are found closer to the shore while red and green algae are more prevalent in offshore areas. “Sediment and pollutants running into the Reef’s waters smother coral and seagrass, are toxic to marine life and contribute to crown-of-thorns starfish outbreaks, and we must continue to work together and do better,” Ms Marsden said.
