Imagine losing coastlines, entire islands, and substantial parts of Asia, northern Europe and the Arctic from erosion, floods, and glacial melting. Imagine the consequences of a year with record heat temperatures.
Can you envision a world constantly hit with hurricanes and tsunamis, afflicted with drowning seals and disappearing polar bears, and impoverished by lost marine environments and arctic livelihoods? Can you further envision the disappearance of coral reefs, and depletion of as much as 1/3 of the species in the oceans due to ocean acidification and climate change?
Now, imagine a world where you could make a difference. Imagine that you could help the world better undersand the oceans, reduce ocean pollution, restore ecosystems, repair damaged marine environments and replenish the oceans' resources.
Can you imagine rebuilding the world's oceans and seas, valuable resources upon which so much of our existence depends? Can you imagine taking on challenges such as climate change impacts, ocean acidification, and bleaching of coral reefs?
As one of our most precious assets, the ocean is indispensable to life itself. It is the largest habitat for living things in our solar system and sustains our lives with over 50 percent of the earth's oxygen. "Without our oceans, we wouldn't be able to breathe; we wouldn't be able to eat; we wouldn't be able to live.'"
The Ocean and coastal resources supply us with:
A vital source of food - The ocean is the primary source of protein for over 2.6 billion people worldwide;
A source of employment and livelihood - Economic activity resulting from the ocean indirectly and directly support 200 - 400 million people each year;
Energy that powers the planet - The oceans hold existing and potential oil and gas reserves for future energy use;
A place for leisure and sports - More than 200 million people visit coastal cities and countries each year;
A place to live - Over half of the world's population live within 200 km of a coastline.
Increasing economic activity and climate change, however, have put our marine environments, and our own existence in great peril. Marine ecosystems are at risk of being lost forever; fisheries are facing declining catches; and island states are threatened by rising sea levels. The specter of global terrorism and nuclear activity in the oceans also pose a great danger to our lives.
Waves of change offers an opportunity to address all of these issues and more. View an introduction to Waves of Change below.

Ocean acidifying 10 times faster than anytime in the last 55 million years, putting polar ecosystems at riskLast Updated on 2014-03-11 09:01:11An assessment of ocean acidification, presented at the UN Climate Change Conference in Warsaw in November 2013, starkly concluded that acidity is on track to rise 170 percent by the end of this century. As many key species are sensitive to changes in acidity, this would drastically impact ocean ecosystems, with effects especially pronounced in polar regions where the cold waters intensify acidification, and which are home to many organisms that are particularly vulnerable to acidification.
The ocean acts as a giant sink for carbon, absorbing 24 million tons of CO2 from the atmosphere every day. Since industrialization, approximately 30 percent of anthropogenic (human generated) CO2 has been absorbed in this way. In the context of climate change this is incredibly important, as the amount of atmospheric CO2 is directly linked to global temperatures. But as CO2 is absorbed, the pH of the... More »
Conservation biologist: Environmental consequences of Keystone ‘epic’Last Updated on 2014-02-05 15:45:59
Conservation biologist Dr. Reese Halter is asked by MSNBC host Craig Melvin to respond to House Speaker John Boehner's call to build the Keystone XL pipleline.
Dr. Halter shares what he thinks would be the environmental dangers the Keystone XL pipeline.
Dr. Halter also responds to the water crisis caused by the West Virginia chemical spill.
Fourth Annual After-Gasparilla CleanupLast Updated on 2014-01-23 17:30:47Tampa Bay Green Consortium, of which the Waves of Change is a member, is happy to announce the Fourth Annual After Gasparilla Cleanup which is scheduled for Sunday, January 26th, from 1 - 4 p.m.
You are invited to help keep parade litter along Bayshore Blvd's parade route from potentially harming marine life. This event also impacts the amount of marine debris that ends up in our Tampa Bay. Tampa Bay Green Consortium is very proud to see our grass roots cleanup event, which started with just 9 people four years ago to a multi-sponsored event with The Florida Aquarium, Keep Tampa Bay Beautiful, Pepin, Hillsborough County, and The City of Tampa supporting this large scale litter removal effort along Bayshore Boulevard.
To volunteer, please Sign Up Here
When you sign up, please put down "TBGC" as the source of where you found out about our event. We... More »
Multiple ocean stresses threaten "globally significant" marine extinctionLast Updated on 2014-01-04 14:54:36
A high-level international workshop convened by IPSO met at the University of Oxford earlier this year. It was the first inter-disciplinary international meeting of marine scientists of its kind and was designed to consider the cumulative impact of multiple stressors on the ocean, including warming, acidification, and overfishing.
The 3 day workshop, co-sponsored by the International Union for Conservation of Nature (IUCN), looked at the latest science across different disciplines.
The 27 participants from 18 organisations in 6 countries produced a grave assessment of current threats — and a stark conclusion about future risks to marine and human life if the current trajectory of damage continues: that the world's ocean is at high risk of entering a phase of extinction of marine species unprecedented in human history.
Delegates called for urgent and... More »
Rising ocean acidification leads to anxiety in fishLast Updated on 2014-01-01 19:09:30by Mario Aguilera
A new research study combining marine physiology, neuroscience, pharmacology, and behavioral psychology has revealed a surprising outcome from increases of carbon dioxide uptake in the oceans: anxious fish.
A growing base of scientific evidence has shown that the absorption of human-produced carbon dioxide into the world's oceans is causing surface waters to decline in pH, causing a rise in acidity. This ocean acidification is known to disrupt the growth of shells and skeletons of certain marine animals but other consequences such as behavioral impacts have been largely unknown.
In a study published in the journal Proceedings of the Royal Society B: Biological Sciences, scientists at Scripps Institution of Oceanography at UC San Diego and MacEwan University in Edmonton, Canada, have shown for the first time that rising acidity levels increase anxiety in... More »
