I post below an article by Richard Black – Environment correspondent, BBC News 20 June 2011

But before I do so, I would like to point out is that we can do something about this. And we don’t have to wait for our governments to make the ‘right’ choices. We know that’s not going to happen soon. At present, the entire Western World’s governments are leaning to the right and support further exploitation of the oceans and the environment in general. Commercial interests and lobbyists exert powerful influences on our elected representatives. No, it’s up to you and me. We make the difference and the choices are ours as individuals to make. Whatever changes you make ultimately reflect on those around you. That may have to be enough for now. You’ll see in the article the recommendations of the scientists involved. I’ve taken their three main recommendations and added a few suggestions for you.

1. Stop exploitive fishing: Consider not eating fish at all, or sourcing only from local, non-exploitive fishermen. Those cans of salmon and tuna have dubious beginnings. Watch the film Sharkwater and you’ll see the horrendous practices involved in feeding the Asian lust for shark fin soup. Support organizations like Sea Shepherd and Greenpeace, who are making a difference.

2. Mapping and then reducing the input of pollutants including plastics, agricultural fertilisers and human waste: There’s much each of us can do here. Buy and grow organic food. Support local growers to reduce the transport pollution associated with the vast distances food is shipped to supermarkets. Take steps to eliminate plastic from your buying. You’ll have to boycott the supermarket to do this. Colin Beavan described how he and his family did this for a year in his book, No Impact Man.

3. Making sharp reductions in greenhouse gas emissions: Get out of your car and onto your bike or your feet. Car pool or take the bus. Eliminate unnecessary trips. Increase the efficiency of heating in your home. The list goes on and on and it starts with each of us.

So here’s what Richard Black wrote.

The oceans are in a worse state than previously suspected, according to an expert panel of scientists. In a new report, they warn that ocean life is “at high risk of entering a phase of extinction of marine species unprecedented in human history.” They conclude that issues such as over-fishing, pollution and climate change are acting together in ways that have not previously been recognised. The impacts, they say, are already affecting humanity.

The panel was convened by the International Programme on the State of the Ocean (IPSO), and brought together experts from different disciplines, including coral reef ecologists, toxicologists, and fisheries scientists.

Its report will be formally released later this week.

“The findings are shocking,” said Alex Rogers, IPSO’s scientific director and professor of conservation biology atOxfordUniversity. “As we considered the cumulative effect of what humankind does to the oceans, the implications became far worse than we had individually realised. We’ve sat in one forum and spoken to each other about what we’re seeing, and we’ve ended up with a picture showing that almost right across the board we’re seeing changes that are happening faster than we’d thought, or in ways that we didn’t expect to see for hundreds of years.” These “accelerated” changes include melting of the Greenland and Antarctic ice sheets, sea level rise, and release of methane trapped in the sea bed. “The rate of change is vastly exceeding what we were expecting even a couple of years ago,” said Ove Hoegh-Guldberg, a coral specialist from theUniversityofQueenslandinAustralia. “So if you look at almost everything, whether it’s fisheries in temperate zones or coral reefs or Arctic sea ice, all of this is undergoing changes, but at a much faster rate than we had thought.”

But more worrying than this, the team noted, are the ways in which different issues act synergistically to increase threats to marine life. Some pollutants, for example, stick to the surfaces of tiny plastic particles that are now found in the ocean bed. This increases the amounts of these pollutants that are consumed by bottom-feeding fish.

Plastic particles also assist the transport of algae from place to place, increasing the occurrence of toxic algal blooms – which are also caused by the influx of nutrient-rich pollution from agricultural land. In a wider sense, ocean acidification, warming, local pollution and over-fishing are acting together to increase the threat to coral reefs – so much so that three-quarters of the world’s reefs are at risk of severe decline.

Life on Earth has gone through five “mass extinction events” caused by events such as asteroid impacts; and it is often said that humanity’s combined impact is causing a sixth such event. The IPSO report concludes that it is too early to say definitively. But the trends are such that it is likely to happen, they say – and far faster than any of the previous five. “What we’re seeing at the moment is unprecedented in the fossil record – the environmental changes are much more rapid,” Professor Rogers told BBC News. “We’ve still got most of the world’s biodiversity, but the actual rate of extinction is much higher [than in past events] – and what we face is certainly a globally significant extinction event.” Some species are already fished way beyond their limits – and may also be affected by other threats.

The report also notes that previous mass extinction events have been associated with trends being observed now – disturbances of the carbon cycle, and acidification and hypoxia (depletion of oxygen) of seawater. Levels of CO2 being absorbed by the oceans are already far greater than during the great extinction of marine species 55 million years ago (during the Paleocene-Eocene Thermal Maximum), it concludes.

The report’s conclusions will be presented at UN headquarters inNew Yorkthis week, when government delegates begin discussions on reforming governance of the oceans.

IPSO’s immediate recommendations include:

  • stopping exploitative fishing now, with special emphasis on the high seas where currently there is little effective regulation  
  • mapping and then reducing the input of pollutants including plastics, agricultural fertilisers and human waste  
  • making sharp reductions in greenhouse gas emissions

Carbon dioxide levels are now so high, it says, that ways of pulling the gas out of the atmosphere need to be researched urgently – but not using techniques, such as iron fertilisation, that lead to more CO2 entering the oceans. “We have to bring down CO2 emissions to zero within about 20 years,” Professor Hoegh-Guldberg told BBC News. “If we don’t do that, we’re going to see steady acidification of the seas, heat events that are wiping out things like kelp forests and coral reefs, and we’ll see a very different ocean.” In the long run, greenhouse gas emissions must be cut to conserve ocean life, the report concludes.

Another of the report’s authors, Dan Laffoley, marine chair of the World Commission on Protected Areas and an adviser to the International Union for the Conservation of Nature (IUCN), admitted the challenges were vast. “But unlike previous generations, we know what now needs to happen,” he said. “The time to protect the blue heart of our planet is now.”

Two nights ago I watched the documentary, Home, with a small group of friends. The film, approaching two hours in duration, is a visual feast. Entirely shot from the air, presumably from a helicopter, it provides an aerial perspective of stunning natural vistas most of us will never see.

It also displays the unprecedented and startling changes humanity has wrought to the earth’s surface in the last fifty years. And it extrapolates that more minerals will be extracted, with ever larger and more powerful machinery, from the planet in the next twenty years than in all of recorded history. (See my earlier related blog Ok Tedi and China Blue)

All this is based on a premise of unlimited, exponential growth and rampant consumerism; that bigger is better. The film makes it abundantly clear we need to act now, if not very soon, to slow the avalanche of destruction and chart a new and gentler course for humanity. We are not walking softly on the earth and the sea at present, rather we are raping and pillaging at a rate sure to severely impact the ability of our children to enjoy this still amazing planet.

I thought the film was well worth viewing from a perspective of earthly beauty. I did feel the focus on the negative lasted too long and was somewhat numbing and disempowering. There were hints of positive possibilities near the end of the documentary with examples from smaller and saner nations like Denmark, Costa Rica and New Zealand.

It would appear the adage, ‘Think globally. Act locally,’ is as apt as ever. The morning after viewing the film, I picked up rubbish from the beach and then spent satisfying hours in the garden creating a huge mound of compost from hedge clippings, garden scraps and seaweed. Once again I felt empowered, knowing I was doing my little bit to make the world a more fertile and better place.
