Humans vs animals — The hottest race of the year - New from BBC Earth
March 2, 2011 06:49 AM - BBC Earth
Imagine a landscape in front of you as barren and endless as your eye can see. And then imagine that your task is to cross it, on foot, through eye stinging dust storms, unbearable heat and a body willing you to stop with every step. Welcome to the Sahara! Welcome to your "marathon of the sands". Aptly named the Sahara meaning "The Great Desert," it is a land-mass almost as large as Europe or the United States! Making it the largest hot desert in the world, second only to Antarctica, which although not commonly thought of as a desert because of its cold climate, is classified as such when the amount of rainfall is measured. The cheetah may be the fastest sprinter on the planet — reaching from 0 to 60mph in less than 3 seconds! But what about over long distances? In this incredible video from Life of Mammals, we see how different animals respond to the challenges of survival that require the use of their fitness and strength.
Brazilian Belo Monte Dam Halted on Judge's Orders
March 1, 2011 09:27 AM - David A Gabel, ENN
In another twist of the Belo Monte Dam saga, a Brazilian judge has ordered that work be suspended on the massive construction project. About one month ago, construction of the dam had been approved by the Brazilian environmental agency, IBAMA. The federal judge, Ronaldo Desterro, said that IBAMA had granted approval for the Belo Monte project under pressure from Norte Energia (a.k.a. NESA), the dam's contractor. The judge also cited concerns over the dam's impact on indigenous tribes and the environment.
When and Where Life Began
March 1, 2011 08:14 AM - Andy Soos, ENN
Almost 600 million years ago, before the rapid evolution of life forms known as the Cambrian explosion, a community of seaweeds and worm-like animals lived in a quiet deep-water niche near what is now Lantian, a small village in south China. Then they simply died, leaving some 3,000 nearly pristine fossils preserved between beds of black shale deposited in oxygen-free and unbreathable waters. Scientists from the Chinese Academy of Sciences, Virginia Tech in the United States and Northwest University in Xi'an, China report the discovery of the fossils in this week's issue of the journal Nature. The long-running puzzlement about the appearance of the Cambrian fauna, seemingly abruptly and from nowhere, centers on three key points: whether there really was a mass diversification of complex organisms over a relatively short period of time during the early Cambrian; what might have caused such rapid change; and what it would imply about the origin and evolution of animals. Interpretation is difficult due to a limited supply of evidence, based mainly on an incomplete fossil record and chemical signatures left in Cambrian rocks. The Lantia discovery suggests a much part of the picture.
Risk Management Rules and Farms
February 28, 2011 08:00 AM - Andy Soos, ENN
Farms do not have highly hazardous chemicals? It is not just factories that use such chemicals but so do farms. ADI Agronomy, Inc., which owns a group of farm supply facilities in southeast Missouri and northeast Arkansas, has agreed to pay a $54,922 civil penalty to the United States for chemical Risk Management Program violations at its Ag Distributors retail facility at Kennett, Mo., which sells liquid fertilizer made with anhydrous ammonia. EPA Region 7 issued an administrative compliance order to the Kennett facility in July 2010, after an inspection noted eight violations of the chemical Risk Management Program regulations contained in the federal Clean Air Act. Specifically, Ag Distributors failed to establish and implement maintenance procedures to ensure the ongoing integrity of its anhydrous ammonia process equipment, and failed to document that the equipment complied with recognized and generally accepted good engineering practices, among other violations.
The Gerat Northern Lights
February 25, 2011 11:43 AM - Andy Soos, ENN
An aurora is a natural light display in the sky, particularly in the polar regions, caused by the collision of charged particles directed by the Earth's magnetic field. An aurora is usually observed at night and typically occurs in the ionosphere. It is also referred to as a polar aurora or, collectively, as polar lights. These phenomena are commonly visible between 60 and 72 degrees north and south latitudes, which place them in a ring just within the Arctic and Antarctic polar circles. Recent increases in solar activity, including the largest solar flare in four years, may lead to hopes of seeing the aurora borealis, also known as the northern lights, in the United Kingdom and other relatively more southern locales. In the United Kingdom, for example, the chances of seeing the aurora increase the further north you go — ranging from one or two displays every 10 years in the south of England to one or two displays a week in the far northern Shetland Islands. Solar variation is the change in the amount of radiation emitted by the Sun and in its spectral distribution over years to millennia. These variations have periodic components, the main one being the approximately 11-year solar cycle (or sunspot cycle). This variation causes the northern lights to vary in location and magnitude.
Islamic Leaders Preach Conservation in Sumatra, Indonesia (updated)
February 25, 2011 07:24 AM - Melanie Jae Martin
Do religious texts mandate respect for the earth and other species? Some Islamic leaders in Sumatra believe the Koran does. In Indonesia, the country with the highest rate of deforestation and some of the most diverse habitat in the world, many Islamic leaders believe religion is the key to conservation. In Sumatra, habitat is disappearing fast, mainly due to oil palm plantations, and populations of animals like the Sumatran orangutan and tiger are dwindling. Education is key to solving the region’s environmental problems, the leaders believe, and religion has the potential to spark wide public interest in environmental awareness. Called FORDALING (the Islamic Leader Forum for Environmental Care), the group believes the Koran directly addresses the need for protecting the natural world. They explain this in their newly released book Ayat-Ayat Konservasi (Islamic Verses for Conservation). Through this book and other projects, these religious leaders have set out to show Indonesian Muslims why conservation should be important to them and the world.
New from BBC Earth: The Monarch Migrates
February 25, 2011 07:12 AM - BBC Earth
Dating back to over 250-million years ago, this simple milkweed butterfly is master of change. With it's name literally being translated from the Greek as "sleepy transformation", the Monarch Butterfly develops from egg to caterpillar to butterfly without a bat of a wing! However this seemingly effortless metamorphosis, lasting approximately two weeks, is just the beginning. Within the mysterious world of this exceptional insect lies a spectacular truth. That in every four generations, the last born will live longer and fly further than any other before them. The typical Monarch's life will last up to four or five weeks taking them through a journey; starting as a tiny creamy white egg planted carefully on the fine leaves of the milkweed, to an energized chrysalis, into a striking tawny coloured butterfly! At which point, it will reach adulthood, fly to find the most tempting source of nectar, reproduce and then die. However some then go further.
New England Beaches Erosion
February 24, 2011 03:16 PM - Andy Soos, ENN
Beach erosion is a chronic problem along many open ocean shores of the United States. As coastal populations continue to grow and community infrastructures are threatened by erosion, there is an increased demand for accurate information regarding past and present trends and rates of shoreline movement. There is also a need for a comprehensive analysis of shoreline movement that is consistent from one coastal region to another. An assessment of coastal change over the past 150 years has found 68 percent of beaches in the New England and Mid-Atlantic region are eroding, according to a U.S. Geological Survey report just released. Scientists studied more than 650 miles of the New England and Mid-Atlantic coasts and found the average rate of coastal change — taking into account beaches that are both eroding and prograding -- was a negative 1.6 feet per year. Of those beaches eroding, the most extreme case exceeded 60 feet per year. The past 25 to 30 years saw a small reduction in the percentage of beaches eroding — dropping to 60 percent, possibly as a result of beach restoration activities such as adding sand to beaches.
DEP Environmental Stewardship Program Grows to More than 500 Participants

The New Jersey Department of Environmental Protection has set up a voluntary program for individuals and businesses to tackle sustainability issues in the state. It rewards those who make the extra effort to reduce their carbon footprint and lead by example. The Environmental Stewardship Program now boasts more than 500 participants, including Ortho Clinical Diagnostics in Raritan, which has erected solar panels to provide green energy. The image shows one of the solar panels as well as DEP inspector Douglas Speeney (center) speaking with OCD's John Nester (left) and Brian Lubbert (right).
