Sustaining Seven Billion People

Sustaining Seven Billion People | green infographics | Scoop.it

"With seven billion people now living on Earth, the ever growing demand is putting unprecedented pressure on global resources—especially forests, water, and food. How can Earth’s resources be managed best to support so many people? One key is tracking the sum of what is available, and perhaps nothing is better suited to that task than satellites."

Daniel LaLiberte's curator insight, July 6, 12:09 PM

Such studies of the agriculture around the world are essential. The way we are doing agriculture to support seven billion people now, peaking at 9-10 billion in another 60 years, it is clear that we are putting severe strains on the environment.  But we have grown lazy, and we are doing it all wrong.

 

We CAN drastically reduce the amount of meat we consume, and thus quickly reduce the amount of arable land we need.  We CAN grow plants in ways that actually sequester more carbon and improve the soil it over time rather than erode and degrade.  And we CAN in fact grow all the food we need in the space we live in, thus enabling us to recycle all the water used as well, which is mostly just lost in evaporation.

Stunning Satellite Images of Earth

Stunning Satellite Images of Earth | green infographics | Scoop.it

Of all the cosmic bodies studied in the long history of astronomy and space travel, the one that got the least attention was the one that ought to matter most to us—Earth.

That changed when NASA created the Landsat program, a series of satellites that would perpetually orbit our planet, looking not out but down. Landsat was built for public monitoring of how the human species was altering the surface of the planet. The space agency, along with the U.S. Geological Survey (USGS), has accumulated a stunning catalog of images that, when riffled through and stitched together, create a high-definition slide show of our rapidly changing Earth, which for the first time date all the way back to 1984.


These Timelapse pictures tell the pretty and not-so-pretty story of a finite planet and how its residents are treating it — razing even as we build, destroying even as we preserve.

Lauren Moss's insight:

The impact of global urbanization, deforestation, and resource depletion are expressed in dramatic satellite imagery and timelapse video of a changing earth.

These depictions show the massive scale of the environmental impact of climate change, rising sea levels and urban growth, and underscore the need to develop a viable plan for addressing these issues.

Many thanks to Seth Dixon for sharing this resource.

I suggest you watch to see the spatial patterns emerge!

Very useful visual tool for exploring patterns of change
