Sustaining Seven Billion People

“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.”

Agricultural production is one of the ways in which people modify the environment more than any other.  Global population is expected to top out at around 9 billion around 2050, so will we be able to sustainably feed all of the entire human population?  Satellite imagery can help answer these questions.

La-Tomatina-in-Valencia2

La Tomatina 2012

La Tomatina is a festival that is held in the Valencian town of Bunol, located inland from the Mediterranean Sea, that brings together thousands of people for one big tomato fight – purely for fun!

La Tomatina is a cultural festival in Spain that is world renowned for it’s exuberance and playfulness.  This gallery of 26 images shows some of the dynamism and appeal to this extraordinary event where more than 40,000 people engage in the world’s largest foof fight using upwards of 100 tons of tomatoes in the yearly food fight known as ‘La Tomatina.’

Notice the signs for storing backpacks and luggage that are now pastered with tomatoes on the store in the background of the image.  These hastily-composed, informal signs are written in three languages (Spanish, English and Japanese).  What does this tell us about the festival?  Also, notice how the comments section revolves around the concepts of waste, poverty and consumption.

Genetically Modified Foods

Via Scoop.itGeography Education

“93% of Americans want the FDA to label genetically engineered foods. Watch the new video from Food, Inc. Filmmaker Robert Kenner to hear why we have the right to know what’s in our food.”

Clearly this video has a political agenda, but this is a pertinent video to show in an Agriculture unit.  Many countries around the world require the labeling of genetically modified food products, while the United States (currently) does not.  The organization that sponsored this video and  Health blog‘s are concerned about how this impacts nutrition in the United States, having uninformed food consumers.  Political action is currently underway in the United States to change this.
