Vultures may not get a lot of love, or respect for that matter, from the public, but they play a vital role in cleaning up and recycling nature’s waste, which also helps prevent diseases from spreading. Vultures were once abundant throughout Asia, but that was until veterinary drug diclofenac became common. Used on cattle and livestock, researchers discovered in 2003 that the drug was toxic to vultures, killing any bird that consumed the deceased livestock. Within years populations plummeted, putting several once-abundant species on the Critically Endangered list.
Rapid response from conservationists, including innovative and unique programs, have provided hope that vultures species may still survive.
New global carbon map for 2.5 billion ha of forests
(05/31/2011) Tropical forests across Latin America, Africa, and Southeast Asia stored 247 gigatons of carbon — more than 30 years’ worth of current emissions from fossil fuels use — in the early 2000s, according to a comprehensive assessment of the world’s carbon stocks. The research, published in the journal Proceedings of the National Academy of Sciences by an international team of scientists, used data from 4,079 plot sites around the world and satellite-based measurements to estimate that forests store 193 billion tons of carbon in their vegetation and 54 billion tons in their roots structure. The study has produced a carbon map for 2.5 billion ha (6.2 billion acres) of forests.
After five years of campaigning, two Girl Scouts fighting palm oil in Girl Scout cookies are receiving wider media coverage this week after meeting with heads of Girl Scouts of the US. The organization has now agreed to research different options, such as sustainably-grown palm oil or using another ingredient, reports the Wall Street Journal. Above, the Girl Scout activists are interviewed on the CBS Early Show.
(05/04/2011) Girls Scouts USA has censored its Facebook page after receiving comments criticizing the organization, according to Rainforest Action Network (RAN). RAN along with Change.org and two Girl Scout activists, Rhiannon Tomtishen and Madison Vorva, declared today a social media day of activism against the Girl Scouts for using palm oil in their popular cookies. The oil has been linked to rainforest destruction in Indonesia and Malaysia.
“On World Oceans Day, Oceana honors those who have made a significant, ongoing contribution to ocean conservation. This year, hundreds were nominated, and a panel of experts selected the following finalists. Vote now for your favorite in both categories: adult and junior. ”
There’s no question that the ocean needs heroes. The world’s oceans, and its wildlife, face significant pressure from a wide variety of human-caused problems: overfishing, climate change, pollution, acidification among others. From coral reefs to sharks to sea turtles, many species are vanishing at unparalleled rates due to these and other issues.
The International Institute for Species Exploration at Arizona State University has selected its top ten new species from 2010. While all the species are extraordinary, one was discovered in a most baffling, manner: taken from the nasal mucous membrane of a person in a Peruvian clinic. This 2-inch leech is named Tyrannobdella rex, which means ‘tyrant leech king’, because of a resemblance to the extinct T-Rex: both share a massive jaw and gigantic teeth. Imagine having that up your nose! The image above shows the Tyrannobdella rex’s anterior sucker exhibiting velar mouth and longitudinal slit through which the dorsal jaw protrudes when feeding. Scale bar is 1 mm. .
The T-rex nose-embedding leech is not the only species though. There’s also the Mozart glowing mushroom, the fruit-eating giant lizard, the spider that weaves the strongest silk, the antediluvian cockroach, among other biological marvels!
(05/23/2011) If we had to characterize our understanding of life on Earth as either ignorant or knowledgeable, the former would be most correct. In 250 years of rigorous taxonomic work researchers have cataloged nearly two million species, however scientists estimate the total number of species on Earth is at least five million and perhaps up to a hundred million. This means every year thousands of new species are discovered by researchers, and from these thousands, the International Institute for Species Exploration at Arizona State University selects ten especially notable new species.
With 6,400 solar cells producing 1.56 megawatts, the Cincinnati Zoo says its new solar parking lot the largest publicly accessible urban solar array in the US. The zoo says that on average the solar array with cover 1/5 of its total energy use and on some days will actually send clean energy back to the grid.
“Innovative projects like this solar canopy showcase the benefits of public and private investment working together to provide a powerful economic boost to communities that need it,” said Assistant Treasury Secretary for Management Dan Tangherlini in a press release. “New Market Tax Credits and a Treasury Recovery Act program that funds renewable energy development helped make this project possible, resulting in new jobs, reduced energy costs and less carbon dioxide being released into the air.”
(03/29/2011) According to a report by the US Pew Environment Group global clean energy investments, which do not include nuclear power, jumped 630% since 2004. The report detailing 2010 clean energy investments found that China remains the global leader in clean energy, while the US fell from 2nd to 3rd. This is the second year in a row that the US fell: in 2009 it lost first place to China. In all $243 billion were invested in clean energy in 2010.
(01/26/2011) Last night US President Barack Obama called for a massive green energy make-over of the world’s largest economy. Describing the challenge as ‘this generation’s Sputnik moment’ the US president set a goal of producing 80 percent of America’s energy by clean sources by 2035. While this may sound improbable, two recent analyses back the president up, arguing that a global clean energy revolution is entirely possible within a few decades using contemporary technology and without breaking the bank. “Based on our findings, there are no technological or economic barriers to converting the entire world to clean, renewable energy sources,” Mark Z. Jacobson, a professor of civil and environmental engineering at Stanford said in a press release. “It is a question of whether we have the societal and political will.”
One billion people in the world are going hungry–more than any other time in history. Yet food security remains a pretty low concern in most industrialized countries. That may not last long according to renowned environmentalist, Lestor Brown, who says that climate change, population growth, rising consumption of meat and dairy, and water issues could soon make food a flashpoint worldwide. Already, high food prices this year played a role in the Arab Spring revolutions and has pushed a number of countries, such as China and South Korea, to begin buying up land in Africa under century-long leases that could create further crises.
Lester Brown is the founder and president of the Earth Policy Institute.
(03/07/2011) As the world’s largest migration in the Serengeti plains—including two million wildebeest, zebra, and Thomson’s gazelles—has come under unprecedented threat due to plans for a road that would sever the migration route, a far lesser famous, but nearly as large migration, is being silently eroded just 1,370 miles (2,200 kilometers) north in Ethiopia’s Gambela National Park. The migration of over one million white-eared kob, tiang, and Mongalla gazelle starts in the southern Sudan but crosses the border into Ethiopia and Gambela where Fred Pearce at Yale360 reports it is running into the rapid expansion of big agribusiness. While providing habitat for the millions of migrants, Gambela National Park’s land is also incredibly fertile enticing foreign investment.
(03/03/2011) Food prices in February hit a new record, breaking the previous one set in January and continuing an eight-month streak of rising prices, according to the Food and Agriculture Organization (FAO). Experts fear that rising food prices could lead to another food crisis similar to that of 2007-2008.
An in-depth look at one figure in the shrimp farming industry, Linda Thorton, who is helping with efforts to create standards for environmentally sustainable shrimp production. Shrimp farming has been a target of environmentalists for links to mangrove destruction and pollution, among other impacts.
