The Wall-E Prophecy

by Dilhan

In the movie ‘Wall-E’ we are transported 700 years into the future, when the last surviving humans have been forced to abandon a polluted Earth and find refuge for their corpulent selves on the spaceship Axiom. The characterization of humans as grossly overweight dugong like creatures, transported in pods – being limited in their ability to move – appears a lot less like the fiction the movie is rated as, when one considers the rate at which human greed and indulgence are evolving. The genius of the movie does not end there, for the polluted and suffocated planet Earth seems to share the same trajectory, although that is probably set to make Wall-E non-fictional a lot sooner than the 700 years suggested in the movie.

Last week the International Union for the Conservation of Nature (IUCN) released an assessment of where the world is with the 2010 target for significantly reducing the rate at which biodiversity was being lost. It makes sobering reading and is without a doubt essential reading for everyone. For all the rhetoric about ‘creative capitalism’, the adaptation of economic systems to meet 21st Century realities and popular desire for greater sustainability, Governments have failed to listen and to act. Read on, please.

Life on Earth is under serious threat, despite the commitment by world leaders to reverse the trend, according to a detailed analysis of the IUCN Red List of Threatened Species™.

The IUCN analysis, which is published every four years, comes just before the deadline governments set themselves to evaluate how successful they were in achieving the 2010 target to reduce biodiversity loss. The IUCN report, Wildlife in a Changing World, shows the 2010 target will not be met.

“When governments take action to reduce biodiversity loss there are some conservation successes, but we are still a long way from reversing the trend,” says Jean-Christophe Vié, Deputy Head of IUCN’s Species Programme and senior editor of the publication. “It’s time to recognize that nature is the largest company on Earth working for the benefit of 100 percent of humankind – and it’s doing it for free. Governments should put as much effort, if not more, into saving nature as they do into saving economic and financial sectors.”

The report analyses 44,838 species on the IUCN Red List and presents results by groups of species, geographical regions, and different habitats, such as marine, freshwater and terrestrial.

It shows 869 species are Extinct or Extinct the Wild and this figure rises to 1,159 if the 290 Critically Endangered species tagged as Possibly Extinct are included. Overall, a minimum of 16,928 species are threatened with extinction. Considering that only 2.7 percent of the 1.8 million described species have been analyzed, this number is a gross underestimate, but it does provide a useful snapshot of what is happening to all forms of life on Earth.

An increased number of freshwater species have now been assessed, giving a better picture of the dire situation they face. In Europe, for example, 38 percent of all fishes are threatened and 28 percent in Eastern Africa. The high degree of connectivity in freshwater systems, allowing pollution or invasive species to spread rapidly, and the development of water resources with scant regard for the species that live in them, are behind the high level of threat.

In the oceans, the picture is similarly bleak. The report shows that a broad range of marine species are experiencing potentially irreversible loss due to over-fishing, climate change, invasive species, coastal development and pollution. At least 17 percent of the 1,045 shark and ray species, 12.4 percent of groupers and six of the seven marine turtle species are threatened with extinction. Most noticeably, 27 percent of the 845 species of reef building corals are threatened, 20 percent are Near Threatened and there is not enough data for 17 percent to be assessed. Marine birds are much more threatened that terrestrial ones with 27.5 percent in danger of extinction, compared with 11.8 percent of terrestrial birds.

“Think of fisheries without fishes, logging without trees, tourism without coral reefs or other wildlife, crops without pollinators,” says Vié. “Imagine the damage to our economies and societies if they were lost. All the plants and animals that make up Earth’s amazing wildlife have a specific role and contribute to essentials like food, medicine, oxygen, pure water, crop pollination, carbon storage and soil fertilization. Economies are utterly dependent on species diversity. We need them all, in large numbers. We quite literally cannot afford to lose them.”

The report shows nearly one third of amphibians, more than one in eight birds and nearly a quarter of mammals are threatened with extinction. For some plant groups, such as conifers and cycads, the situation is even more serious, with 28 percent and 52 percent threatened respectively. For all these groups, habitat destruction, through agriculture, logging and development, is the main threat and occurs worldwide.

In the case of amphibians, the fungal disease chytridiomycosis is seriously affecting an increasing number of species, complicating conservation efforts. For birds, the highest number of threatened species is found in Brazil and Indonesia, but the highest proportion of threatened or extinct birds is found on oceanic islands. Invasive species and hunting are the main threats. For mammals, unsustainable hunting is the greatest threat after habitat loss. This is having a major impact in Asia, where deforestation is also occurring at a very rapid rate.

“The report makes for depressing reading,” says Craig Hilton Taylor, Manager of the IUCN Red List Unit and co-editor. “It tells us that the extinction crisis is as bad, or even worse, than we believed. But it also shows the trends these species are following and is therefore an essential part of decision-making processes. In the run-up to 2010, the global community should use this report wisely to address the situation.”

Climate change is not currently the main threat to wildlife, but this may soon change, according to the report. After examining the biological characteristics of 17,000 species of birds, amphibians and reef building corals, the report found that a significant proportion of species that are currently not threatened with extinction are susceptible to climate change. This includes 30 percent of non-threatened birds, 51 percent of non-threatened corals and 41 percent of non-threatened amphibians, which all have traits that make them susceptible to climate change.

Red List Indices make it possible to track trends of extinction risk in groups of species. New indices have been calculated and provide some interesting results. Birds, mammals, amphibians and corals all show a continuing deterioration, with a particularly rapid decline for corals. Red List Indices have also been calculated for amphibian, mammal and bird species used for food and medicine. The results show that bird and mammal species used for food and medicine are much more threatened. The diminishing availability of these resources has an impact on the health and well-being of the people who depend on them directly.

“The IUCN Red List provides a window on many of the major global issues of our day, including climate change, loss of freshwater ecosystems and over-fishing,” says Simon Stuart, Chair of the IUCN Species Survival Commission and co-editor. “Unless we address the fundamental causes of unsustainability on our planet, the lofty of goals of governments to reduce extinction rates will count for nothing.”

The background:

· In 2002, almost all governments committed to the 2010 biodiversity target “to achieve by 2010 a significant reduction of the current rate of biodiversity loss at the global, regional and national level as a contribution to poverty alleviation and to the benefit of all life on Earth”. The way the 2010 target was phrased highlights the reasons why we should care about nature: its utilitarian value and the fact that it is essential to human wellbeing, but also its intrinsic value (aesthetical, spiritual and recreational).

· Although only 2.7 percent of the world’s 1.8 million described species have been assessed so far, the IUCN Red List provides a useful snapshot of what is happening to species today and highlights the urgent need for conservation action.

· The IUCN Red List has a long established history as the world’s most comprehensive information source on the global conservation status of plant and animal species. It is based on an objective system of assessing the risk of extinction for a species. Species listed as Critically Endangered, Endangered or Vulnerable are collectively described as threatened. The IUCN Red List is not just a register of names and associated threat categories. It is a rich compendium of information on the threats to the species, their ecological requirements, where they live, and information on conservation actions that can be used to reduce or prevent extinctions.

· Wildlife in a changing world consists of a detailed analysis of The IUCN Red List and presents the results by groups of species and biomes (freshwater, marine, terrestrial). It also explains in detail what the Red List really is, how the assessments are conducted, emphasizing the great progress made in recent years to broaden the diversity of species included on the List. One chapter is dedicated to the growing threat represented by climate change. It also includes a section dedicated to the Mediterranean region, a biodiversity hotspot under threat, where our knowledge of biodiversity has greatly increased in recent years.

· Birds are the best known group with less than one percent of species classified as Data Deficient, meaning that we do not have enough information to say if they are threatened or not. However, for many groups, we cannot say what the situation is for a large proportion of species and many of them could well be threatened: 47 percent of 1,045 species of sharks and rays, 35 percent of marine mammals and 24 percent of amphibians are Data Deficient.

· It is not all bad news. Species can recover with concerted conservation efforts. In 2008, 37 improvements in status were recorded for mammals. An estimated 16 bird species avoided extinction over the last 15 years due to conservation programmes. Conservation does work, but to mitigate the extinction crisis much more needs to be done, and quickly. “Conservationists are often considered as alarmists but we need to continue to alert decision-makers to the risk of inaction and the need to give up short term political strategies solely based on economic results,” says Vié. “As shown by the economic and financial crisis, people who raise warning flags should be listened to. Wildlife needs an increased level of attention and our society needs to undertake major changes to safeguard its own future.”
