How might we keep the lights on, water flowing, and natural world vaguely intact? It starts with grabbing innovative ideas/examples to help kick down our limits and inspire a more sustainable world. We implement with rigorous science backed by hard data.

The word “anthropocene” has become the closest thing there is to common shorthand for this turbulent, momentous, unpredictable, hopeless, hopeful time—duration and scope still unknown
PIRatE Lab's insight:
Good, wide-ranging discussion of the era we have all created for ourselves.

"Data viz extraordinaire Max Galka created this map using NASA’s gridded population data, which counts the global population within each nine-square-mile patch of Earth, instead of within each each district, state, or country border. Out of the 28 million total cells, the ones with a population over 8,000 are colored in yellow."
Tags: population, density, mapping, visualization.

Great simple map of world population. Scroll down and look at the U.S. It reflects the global trend. This also has political implications, as evidenced by voting patterns in the 2012 presidential election. Elections are dependent upon votes, which come from people, which are primarily clustered in cities. Election campaigns would use this data to plan their schedules as to where to focus their campaigning efforts. For the folks in Wyoming, they rarely see candidates other than during the primaries. And these world populationclusters have been relatively consistent historically, particularly in south and east Asia. Northern India has serious carrying capacity challenges. Notice the clusters along the Nile- evidence of arable land.

Indian villagers walk towards the Mahan forest during a protest against a coal mining project in Singrauli district, Madhya Pradesh. Of the 14,000 sq km of forests cleared over the past three decades in India, the largest area was given to mining (4,947 sq km), followed by defence projects (1,549 sq km) and hydroelectric projects… Via Garry Rogers

"In which John examines the progress of the UN's Millennium Development Goals over the last 15 years and looks ahead to the Global Goals. Can we live in a world where extreme poverty and undernourishment are rare? Are we closer to gender equality? How have infant mortality rates and maternal mortality rates changed in the last 25 years? And how will we ensure that the astonishing progress since 1990 continues?"

Brewers say that contaminated groundwater would ruin a centuries-old tradition and industry. "When the Bavarian Purity Law was first declared in 1487, not a single European had stepped on the land above the Marcellus Shale in the Eastern United States. The First Nations of Canada weren’t fighting natural gas pipelines, because as far as natural resources go, the Alberta tar sands were centuries away from being in the picture—as was the internal combustion engine. "Yet the law, the Reinheitsgebot, which strictly dictates the ingredients that can be used in making beer, is giving the powerful German brewing industry historic ammunition against the creeping potential for new natural gas exploration.

In the United States, people have begun recycling their urine. How can the beer makers complain about using filthy water; the issue has been discussed ever since indoor toilets were invented. |

California's birth rate drops to a historic low as more people attend college and delay having kids.
PIRatE Lab's insight:
This is a key, but longterm, change in our population dynamics. This should not be read as a declining population per se as we have lots of migration bringing folks into the state. Immigration more than offsets our declining birth rates and any emigration.

It took 200,000 years for our human population to reach 1 billion—and only 200 years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average. When will our global population peak? And how can we minimize our impact on Earth’s resources, even as we approach 11 billion?

This relates to our topic by showing that our population is growing rapidly. By the time 2025 there will be more than 11 billion people on the Earth. But we have enough resources to last us.

"We must recognize that we shot past the opportunity to stabilize our population at a sustainable level of 2 billion about 80 years ago. We must now focus on humanely reducing population on the planet. Some recognize this harsh truth, but most are focused on symptoms. The issue of overpopulation is feared, ignored, misunderstood, falsely represented and demonized by people from all political and religious persuasions. The concept of too many people using up the earth’s limited resources lies outside the parameters of the typical activist’s world. It flies in the face of current norms and doesn’t fit into society’s dominant anthropocentric worldview. Via Garry Rogers

GR: This is a well-written review of an excellent book on population. For Earth: We need to act now to stop greenhouse-gas emissions, and we need to act now to begin reversing our population.

Just last week, Elon Musk revealed that one of his main goals for Space Exploration Technologies (SpaceX) is to eventually build a city on Mars, ushering in an age when humanity is a multi-planet dwelling species.
