Over 300 Western Australian sharks are now on twitter

The Surf Life Saving Western Australia (SLSWA) is using their Twitter feed to put a new, internet-savvy spin on wildlife conservation. The project uses radio transmitter tags on sharks combined with proximity monitors to report on shark movement near human-populated beaches.

A tagged shark within a certain radius of the monitor triggers a tweet informing beachgoers, helping to improve safety for both man and marine beast.

Currently, 338 sharks have been tagged with radio transmitters including a significant number of the more dangerous tiger shark and great white shark species. The tweet states the breed and estimated size of the shark along with an approximate location. The Twitter also broadcasts shark alerts reported from other sources, such as helicopter sightings.

The system is reported to be much faster than traditional radio warnings, and allows lifeguards to shut down beaches in a timely manner with a minimum of panic and disruption.

As a bonus, the Twitter occasionally posts raw images of sharks and other marine wildlife in their natural environment off the Western Australian coast.

Vast freshwater reserves found under the ocean

As current sources of drinkable water dwindle, scientist may have found the answer under the ocean of all places. “The volume of this water resource is a hundred times greater than the amount we’ve extracted from the Earth’s sub-surface in the past century since 1900,” says Vincent Post, the Australian groundwater expert and lead on the project.

The report estimates 500,000 cubic kilometers of low salinity water buried under various seabeds around the world that could be reached using platforms that are similar to offshore oil rigs that are used today. The water is not immediately drinkable, but much easier to desalinate than salt water and comparable dry land basins have been used in the past.

Challenges include setting up drilling operations, which would incur a large initial cost, and using the water effectively. “We should use them carefully: once gone, they won’t be replenished until the sea level drops again, which is not likely to happen for a very long time,” warns Post. Overuse or contamination of these reserves would result in a major loss of resources that we may literally need to survive.

Hillary Clinton and Harrison Ford Lead Conversation on Conservation, Julio Mario Santo Domingo Honored

Former Secretary of State Hillary Clinton and Harrison Ford open up a powerful conversation about natural resources and sustainability at the annual Conservation International Gala. Ford is the Conservation International (CI) Vice Chairman, an organization whose mission is to ensure the sustainability of natural resources for the well-being of people. The New York City event with nearly 450 guests raised more than $1.6 million dollars.

Secretary Clinton and Ford took the stage where they spoke passionately about a range of urgent environmental challenges. They also raised the issue of security threats in vulnerable regions from sub Saharan Africa, to the Greater Mekong region of Southeast Asia, to the low-lying atoll nations of the Central and South Pacific. Threats an challenges have risen due to resource scarcities, illegal wildlife trade and global climate change.

Ford told a story about a dinner he had with Secretary Clinton and CI co-founder, CEO and Chairman Peter Seligmann several years earlier.  Ford recounted about when he learned conservation failures abroad could become national security issues for the United States and other countries.  “We have reached a point in our human history where nature may be unable to support the weight and the appetites of the planet’s human population.  We’ve weakened the natural world’s capacity to provide us with fresh water, natural pollinators for our crops, food, botanical sources of future medicines.”

They also discussed emerging tensions resulting from the polar ice cap melt and the issue of illegal wildlife trade.

“The Arctic, I think, is one of the most important conservation issues facing the world today,” said Clinton. “Organizations like CI and others need to be knocking on the doors of governments and making it clear that it is in all of our enlightened self interest to come up with a plan for the protection, the preservation and use of the Arctic in as environmentally sustainable and responsible way as possible.”

“We have a crisis. We have a wildlife, poaching, trafficking, murdering crisis,” she warned, emphasizing the plight of African elephants, mass murdered for their ivory in an international trade that often arms militant groups and funds organized crime. “It is not only criminal enterprises but is carried out by highly armed vicious bands who sometimes arrive in helicopters with night- vision goggles and their assault weapons,” said Clinton.

Conservation International also paid tribute to former board member Julio Mario Santo Domingo with a posthumous award as Global Conservation Hero. Mr. Santo Domingo, helped raise awareness about the importance of healthy ecosystems in Latin American economies, biodiversity and people.

“He has influenced our board, influenced our organization and impacted everybody in our institution.  He was one of the most extraordinary men that I ever encountered; a citizen of the world,” said Silegmann.

“All told, with the inspiration of Julio Mario Santo Domingo, Colombia has protected with CI, ten million hectares on land and at sea, which is equal to an area four times the state of New Jersey. We are honored to recognize Don Julio Mario Santo Domingo for his vision that his native land could be a beacon on the hill for sustainability and the commitment he made to making that vision a reality.”

Julio Mario Santo Domingo’s sons, Andres and Alejandro accepted the award on behalf of their father.

“The most important lesson my father gave me is by his example: Be kind to people, be kind to everything,” said Andres Santo Domingo, dinner chairman.

Andres Santo Domingo and his wife, Lauren also help organize fundraisers for Conservation International.

Must see documentaries

If you have a chance to see these films, I suggest watching “To the Arctic” and “Born to be Wild.”

You’ll get a glimpse into the life of polar bears, baby elephants and orangutans! These baby animals are dependent on their mothers to survive, but poaching, encroachment and global warming threaten their chances of survival.

It will make you reconsider your excessive consumption of resources on this earth.
