People around the world are beginning to address the problem by reducing their carbon footprint through less consumption and better technology. But unsustainable human population growth can overwhelm those efforts, leading us to conclude that we not only need smaller footprints, but fewer feet. Portland, Oregon, for example, decreased its combined per-capita residential energy and car driving carbon footprint by 5 percent between 2000 and 2005. During this same period, however, its population grew by 8 percent. A 2009 study of the relationship between population growth and global warming determined that the “carbon legacy” of just one child can produce 20 times more greenhouse gas than a person will save by driving a high-mileage car, recycling, using energy-efficient appliances and light bulbs, etc. Each child born in the United States will add about 9,441 metric tons of carbon dioxide to the carbon legacy of an average parent. The study concludes, “Clearly, the potential savings from reduced reproduction are huge compared to the savings that can be achieved by changes in lifestyle.” One of the study’s authors, Paul Murtaugh, warned that: “In discussions about climate change, we tend to focus on the carbon emissions of an individual over his or her lifetime. Those are…

Macron kills waders, bird lovers angry

https://youtu.be/ecJSoImIT2Y This video from Britain says about itself: 17 August 2016 Godwits are large, elegant waders and relatively common in the right habitats at certain times of year. The two commonly encountered species, Black-tailed and Bar-tailed Godwit, should be reasonably straightforward to separate, although their eponymous tail markings may not always be the easiest feature to use! Some birds such as juveniles or out of context lone birds can prove more problematic, however, and this workshop will help you to confidently identify both species. Translated from Dutch NPO radio today: Conservationists angry with France about shooting of shorebirds Nature organizations in the Netherlands and Belgium are angry about the decision of the French government to extend the hunting ban on the godwit with only one year, until 2020. This means that from then on it will be possible again to shoot godwits. “And to think that a lot of money is spent in the Netherlands and Belgium to protect the birds”, says Hendrik Moeremans of Natuurpunt in Belgium to News en Co on NPO Radio 1. So far, the hunting ban on the black-tailed godwit in France had been extended twice by five years, so it has been forbidden for ten years to hunt the bird. According to Moeremans, strong signals are coming from France that the hunting ban will be lifted from 2020 onwards. “There is a very strong hunters’ lobby there.”…

Ice Age American elephants

Many of us will be well-aware of these groups, but what of some of the lesser-known proboscideans? One such family are the gomphotheres and in this episode we’re introduced to them by Dr Dimila Mothé, of the Federal University of the State of Rio de Janeiro, Brazil. By Alexandra Witze in the USA, 12:30pm, November 13, 2018: How mammoths competed with other animals and lost Human hunters helped wipe out mammoths, mastodons and gomphotheres The Gray Fossil Site, a sinkhole in northeastern Tennessee, is full of prehistoric treasures. Between 7 million and 4.5 million years ago, rhinoceroses, saber-toothed cats and other creatures, even red pandas, perished here by the edge of a pond. But that bounty of fossils pales next to the site’s biggest find: a mastodon’s skeleton, nearly 5 million years old, preserved in exquisite detail all the way down to its ankle bones. “It is just fantastic”, says Chris Widga, a paleontologist at East Tennessee State University in nearby Johnson City. The ancient elephant relative became known as Ernie because it was enormous, calculated soon after its 2015 discovery to have weighed 16 tons in life. The name came from musician Tennessee Ernie Ford, known for the coal-mining song “Sixteen Tons”. Since then the researchers have revised the…
