Bad Earth: the human cost of pollution in China – in pictures

Bad Earth: the human cost of pollution in China – in pictures | STEM Connections | Scoop.it
This series of images shows the extent of China’s pollution problems and the human toll of exponential growth on local communities in China’s vast and severely damaged northern region

 

Ghazlan Mandukai, 52, left, looks out over the vast, toxic tailings lake beyond the industrial city of Baotou, Inner Mongolia. He farmed in this area for 40 years until the influx of steel and rare earth metal factories rendered local lands infertile. Poisonous waste that results from refining rare earths is continually dumped into the Weikuang Dam, as seen here.

How ‘Ugly’ Fruits and Vegetables Can Help Solve World Hunger

How ‘Ugly’ Fruits and Vegetables Can Help Solve World Hunger | STEM Connections | Scoop.it
About a third of the planet’s food goes to waste, often because of its looks. That’s enough to feed two billion people.

Katerina Stojanovski's curator insight, March 10, 6:10 AM

No one should be surprised that more developed societies are more wasteful societies.  It is not just personal wasting of food at the house and restaurants that are the problem.  Perfectly edible food is thrown out due to size (smaller than standards but perfectly normal), cosmetics (Bananas that are shaped 'funny') and costumer preference (discarded bread crust).  This is an intriguing perceptive on our consumptive culture, but it also is helpful in framing issues such as sustainability and human and environmental interactions.  In a technologically advanced societies that are often removed form the land where the food they eat originates, food waste needs to made more explicit.

The Geography of E-Waste

The Geography of E-Waste | STEM Connections | Scoop.it
The world is increasingly going hi-tech. Many people in our high consumption society want the latest and the greatest; last year’s much anticipated laptops and cell phones are miles behind the newest models that are coming out. So what happens with the old models? Even thrift stores are politely not accepting them as donations. Even some workable machines that were highly valuable 10 years ago are now functionally trash in our society. We can’t put it to the curb to end up in the landfill because of the lead, mercury, and other hazardous materials that can leak into the environment. This type of trash is what we call e-waste. The geography of e-waste is an ‘out of sight out of mind’ problem that we rarely think about but need to due to the ecological impacts of our collective consumption.

Food Waste

Producers, sellers, and consumers waste tons of food. John Oliver discusses the shocking amount of food we don’t eat.

Bonnie Bracey Sutton's insight:

Food waste is a tragedy that we all know happens, but the economic system does not work efficiently to maximize the global food production (Disclaimer: it is HBO's John Oliver, so there is some language and references that might not be appropriate for all audiences).

Sustaining Seven Billion People

Sustaining Seven Billion People | STEM Connections | 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, 2014 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.

The large-scale agricultural practices of modern America tend to lend to the bad image of commercial farming. However, the practices are actually helping feed more people in the US, but they also use genetically modified crops and other highly debated techniques.

Lauren Sellers's curator insight, May 20, 2014 11:45 AM

Yes it does because in all large scale endeavors, regardless of what for, the quality is always sacrificed for the quantity because it becomes cheaper to produce and profits are greater.

BrianCaldwell7's curator insight, March 16, 3:56 PM

In the long run, a successful farmer needs to find a balance between economic and environmental sustainability.  Some big farms are working towards that so the 'big-equals-bad' narrative about agriculture may be easy, but it doesn't tell the whole story about modern agriculture.

The Periodic Table of Elements Scaled to Show The Elements’ Actual Abundance on Earth

The Periodic Table of Elements Scaled to Show The Elements’ Actual Abundance on Earth | STEM Connections | Scoop.it
When you learned about The Periodic Table of Elements in high school, it probably didn’t look like this. Above, we have a different way of visualizing the elements. Created by Professor William F. Sheehan at Santa Clara University in 1970, this chart takes the elements (usually shown like this) and scales them relative to their abundance on the Earth’s surface.

The Ogallala Aquifer

The Ogallala Aquifer | STEM Connections | Scoop.it
Hidden beneath the 245,000 square miles that make up the Great Plains, resides a lake that’s one of our greatest water assets: The Ogallala Aquifer. Haven’t heard of it? Farming the plains would be unprofitable at best without it, as shown by the Dust Bowl of the 1930s. At the time, the aquifer’s existence was known, but the technology to tap into it wasn’t.

Seth Dixon's curator insight, September 22, 2015 9:27 AM

Portions of the High Plains Aquifer are rapidly being depleted by farmers who are pumping too much water to irrigate their crops, particularly in the southern half in Kansas, Oklahoma and Texas.  This podcast explores the environmental and economic impacts of this unsustainable situation.

Feeding Our Hungry Planet

"By 2050, the world's population will likely increase 35 percent. But is growing more food the only option—or even the best? National Geographic investigates the challenges and solutions to feeding everyone on our planet, based on an eight-month series in National Geographic magazine.  Visit http://natgeofood.com for ongoing coverage of food issues as we investigate the Future of Food today on World Food Day."

I think I might as well buy some land and plant my own huge garden for this crap coming up and have a fence around my yard too

Nancy Watson's curator insight, October 19, 2014 8:53 AM

Population increase is just part of the story. How do we feed everyone? How will we provide for the needs of everyone?  Can the earth sustain the use of her resources and the impact of our growing needs and output. First we must eat. Can we learn to do that wisely? 

Bella Reagan's curator insight, November 28, 2014 5:48 PM

Unit 2-Population

 

This video was about the growing population in the world and as a result the growing food demand. This video points out that even though more food production seems like the solution, instead other solutions are more logical. Solutions include reducing wastes, preserving forests, being more productive on current farms and more. It states that farming is a huge business but it goes towards more than growing food for people to eat but also for other things like animals and materials. The worlds population is growing and there needs to be a change in food industries to keep thriving. 

 

This relates to unit 2 about population since it is thinking of ways to adapt to the worlds growing population. By 2050 it is predicted that population will increase by 33% and something has to change about food in order for people to stay fed. There is too much food being wasted that if that could be decreased it could make a huge difference. The video made a good point that it's not that we need more food it's that we need to manage and prioritize production.
