In 2013, the world consumed an estimated 107 million tons of pork—half of which was eaten in China. China’s 1.4 billion people now consume six times as much pork as the United States does. Even with its recent surge in pork, however, China’s overall meat intake per person still totals only 120 pounds per year, scarcely half the 235 pounds in the United States. But, the Chinese, like so many others around the globe, aspire to an American lifestyle. To consume meat like Americans do, China would need to roughly double its annual meat supply from 80 million tons to 160 million tons. Using the rule of thumb of three to four pounds of grain to produce one pound of pork, an additional 80 million tons of pork would require at least 240 million tons of feedgrain.
Scientists have been reconstructing the history of the moon by scouring its surface, mapping its mountains and craters, and probing its interior. What are they learning about our own planet’s beginnings?
Decades ago, we sent astronauts to the moon as a symbol of confidence in the face of the great cold war struggle. Landing on the moon was a giant leap for mankind. But it’s what the astronauts picked up from the lunar surface that may turn out to be Apollo’s greatest legacy.
When the astronauts of Apollo stepped out of their landing craft, they entered a world draped in fine sticky dust, strewn with rocks, and pocked with craters. They walked and rambled about, picking up rocks that they packed for the return flight.
A old Sunspot (now called AR1990, formerly AR1967) has made its way back around to the Earth-facing side of the Sun. It has unleaded a X4.9-class solar flare that ejected a bright glob of plasma on February 24th, 2014 (EST). — Read more about it here: http://goo.gl/j6yyA6
Last year the amount of energy produced from coal in Germany rose to its highest level since the 1990’s. That’s despite a campaign to shift to greener sources of energy. RT’s Lucy Kafanov visited a small town there, which now risks being destroyed by the country’s coal addiction.
Maria Leticia Lopez Zepeda from the National Association of Producers’ Enterprises del Campo (ANEC) speaks to Newsclick about the agrarian conditions in Mexico. She says the signing of NAFTA has devastated Mexican agriculture as its markets are dumped with cheaper priced agro-products, specially from the United States. This has badly affected the livelihood of the farmers.
Commercial drones — the unmanned planes doing regular tasks — are in growing use around the world. Some assignments for these unmanned aircraft might surprise you, others will amaze you. VOA’s Carolyn Presutti reports on the countries leading the way and why the United States is so far behind.
It’s hard enough to build one spacecraft, but the Magnetospheric Multiscale Mission (MMS) is building four. Together, the spacecraft will unlock the mysteries of magnetic reconnection, when magnetic fields explosively connect and disconnect, transferring energy. MMS will measure reconnection between the sun’s and Earth’s magnetic fields. We want to learn more about magnetic reconnection because it can affect systems like GPS, radio communication, and electrical power grids.
Welcome to Transition Studies. To prosper for very much longer on the changing Earth humankind will need to move beyond its current fossil-fueled civilization toward one that is sustained on recycled materials and renewable energy. This is not a trivial shift. It will require a major transition in all aspects of our lives.
This weblog explores the transition to a sustainable future on our finite planet. It provides links to current news, key documents from government sources and non-governmental organizations, as well as video documentaries about climate change, environmental ethics and environmental justice concerns.
The links are listed here to be used in whatever manner they may be helpful in public information campaigns, course preparation, teaching, letter-writing, lectures, class presentations, policy discussions, article writing, civic or Congressional hearings and citizen action campaigns, etc. For further information on this blog see: About this weblog. and How to use this weblog.
