Hi all
Earth Hour is a global movement that encourages individuals, businesses and governments around the world to take positive actions for the environment, and celebrating their commitment to the planet by switching off their lights for one hour. This year, Earth Hour will be held on Saturday March 26 between 8.30PM and 9.30PM.
During this hour, people will be encouraged to turn off their lights and all non-essential electrical appliances. By raising awareness in this way we hope that this will be the first step to making a commitment that will go beyond the hour by making small but long term changes.
As you know I have been travelling the world’s oceans investigating and teaching about global issues such as climate change and ocean acidification. I have visited coral reefs that are dying because the seas are becoming warmer and discovered how it is also affecting marine food webs.
Ocean acidification is caused as the oceans have absorbed increasing amounts of carbon dioxide from the air. This has upset the ocean chemistry causing oceans to become more acidic. This rise in acidity means the oceans cannot holds as much calcium carbonate, which is the building blocks of corals, crab shells and seashells. In some oceans these animals are already struggling to build their shells, but if it continues to rise we will start to see these animals’ shells beginning to dissolve.
Earth Hour started in 2007 in Sydney, Australia when 2.2 million individuals and more than 2,000 businesses turned their lights off for one hour to take a stand against climate change. One year later it had become a global sustainability movement with more than 50 million people across 35 countries and territories participating.
So why not join me during Earth Hour by turning off all unnecessary lights as lights will switch off around the globe.
