Air quality in China is bad, it’s really, really bad. The air quality is so poor that residents rarely see the sun and in some cities, the dense air pollution is mistaken for snow! What is causing all of the pollution? It’s coal-burning smog. And until China can ween itself from fossil fuels and implement more sustainable energy practices, other energy solutions are desperately needed. One designer named Daan Roosegaarde may have an ingenius solution.
Roosegaarde has an idea to create what he is calling an “electronic vacuum cleaner”. Copper Tesla coils buried underground would help to create an electrostatic field that would pull smog particles down from the polluted sky, creating a clear space above where sunlight could shine through.
His smog vacuum would attract pollution particles much like a strand of hair is pulled toward a statically charged balloon. Copper coils would create a field of static electric ions which would magnetize the smog, causing it to fall down to the ground below. Roosegaarde plans to capture all of the smog on the ground and compress it, hopefully making it easier to create awareness of how much smog residents are living with and to rally opposition to the causes of the polluted air.
This week Roosegaarde created a working prototype with the help of the University of Delft. They were able to take a 5×5 meter room full of smog and create a smog-free hole of one cubic meter with their device. Now the challenge is how to apply it on a grander scale. Roosegaarde would like to see it installed in parks and public spaces where everyone can enjoy a smog free sky.
Over the course of the next 12 to 18 months, Roosegaarde will be working to perfect his device and many will be watching, waiting, and hoping for his success. Roosegaarde acknowledges that the smog plaguing China is “a human problem not a technological problem” and he hopes that his smog-cleaning vacuum will help raise awareness off the issue while also taking a small step to make the air quality and quality of life a little better for the residents of China.
Plastics recycling can have a big impact on our resources.
Shopping bags, liters of soda, cereal box lining, and lots and lots of water bottles — it’s easy to amass plastic in today’s world, given its omnipresence in the products we use. Most of that, though, goes straight into plastic trash bags and heads to a landfill. (The rate of recycling plastic bottles has held steady since the 1990s at about 24 percent.)
Why Recycle Plastic?
When contemplating whether recycling plastic is really worth it, consider the following:
– It costs more money to drink bottled water than to put gas in your car — up to five times more — due mainly to its packaging and transportation, says the Earth Policy Institute.
– Recycling 1 ton of plastic saves 7.4 cubic yards of landfill space.
– The energy we waste using bottled water would be enough to power 190,000 homes.
– More than $1 billion worth of plastic is wasted each year.
– Recycled plastic can turn into a whole host of new and useful products, including durable building and construction products, fiber for carpets, tote bags, beverage bottles, recycling bins, shipping envelopes, and tableware (cups, plates, and utensils). Dolphin Blue carries a complete line of post-consumer recycled plastic tableware, which you can find here.
How to Recycle Plastic
Fortunately, 80 percent of Americans have access to a plastics recycling program, and more than 1,600 businesses are involved in recycling post-consumer plastics. There are seven types of plastic, and not every community’s curbside program recycles all of them, so first, learn what’s what with the handy chart from the American Chemistry Council, found here. Most likely you have #1 (water bottles, peanut butter jars), #2 (plastic bags, shampoo bottles), and #6 (packing peanuts, yogurt containers).
Many stores will recycle plastic bags for you, so check with your favorite grocer, or visit PlasticBagRecycling.org for a list of locations in your state that offer drop-off bins for recycling plastic bags.
When it comes to water bottles and other containers with lids, take the tops off before throwing them in a recycling bin. Lids are usually made of a different type of plastic than bottles, and the recycling facilities aren’t going to take the time to take off billions of lids — and likely will reject the bottles for recycling.

The DIY Guide to Reusing Plastic
There are ways to make good use of plastic once you’re done with it other than sending it to a recycling facility. Keeping plastic bags on hand and reusing them as long as they’re functional is a great way to reduce your impact. To make it convenient, try storing bags in empty tissue or garbage-bag boxes. This keeps the clutter at bay, and it makes the bags accessible when you need them. Just pull a bag out of the parachute hole and go.
For those with an artistic side, look at plastic products in a new way and see what you can come up with. You might just end up with something as fun and elegant as these cascade chandeliers. And although crocheting is usually done with yarn, when plastic bags are the material, it’s environmentally friendly and pretty darn cool. Check out one woman’s creations here.
Last but not least, it’s simple and easy to stock your office kitchen or home pantry with Preserve Tableware, made of post-consumer recycled yogurt cups, available on Dolphin Blue’s site here.
Elephants are being poached for their ivory at the highest rate ever recorded. Current estimates put the figure at 36,000 elephants killed annually, equating to one elephant dying every 15 minutes.
The International March for Elephants organized by iworry, a campaign by the David Sheldrick Wildlife Trust, was created to sound a warning that the future survival of elephants is in serious jeopardy.
Elephants share the same emotions as humans. They have a strong sense of family and mourn the deaths of their loved ones, just as we do. Elephants have unique personalities like us, too! They can be playful or mischievous; they can even hold grudges.
The David Sheldrick Wildlife Trust has learned the beauty of elephants first hand and they have also witnessed the terrible impact of the renewed ivory poaching that we are seeing today. In just 18 days in September, they were called on to rescue 14 orphaned elephants. To date, they have arrested 1,406 poachers and their veterinary teams have successfully treated over 500 wounded elephants.
The International March for Elephants is demanding stronger laws and penalties associated with wildlife crime in countries where poaching and ivory trafficking occurs; increased levels of investment in anti-poaching initiatives by international governments; increased diplomatic pressure on countries where elephants live; and pressure on those nations that fuel the demand.
According to a new report published by The Natural Resources Defense Council and Harvard’s Food Law and Policy Clinic, 9 out of 10 Americans throw away perfectly edible food because of inconsistent labeling of expiration dates and sell-by dates. The report explains the confusion consumers feel over the dates stamped on food packaging and they propose improvements to current policies to help curve the problem.
Many consumers do not understand what the dates on their food products actually mean. Many think the dates designate food safety when in reality they are indicating freshness, not spoilage. Evidence shows that consumers rely too heavily on label dates resulting in food being thrown out over unfounded safety concerns. Experts suggest that consumers focus on more relevant risk factors regarding their food, such as time and temperature control.
The researchers found that inconsistency of terms and dates on packages complicate the matter for consumers. They are calling for national standardization of the words used on packages and clarification to clearly distinguish between safety-based dates and quality-based dates. This would eliminate the commonly found and confusing “sell by” label on consumer packaging as it only pertains to retailers.
When it comes to food safety, common sense is the best defense. “Use-by” dates are only estimates and if your food shows no sign of spoilage then it is most likely still edible. It is always better to err on the side of caution if you feel your food has expired, but do not rely solely on the date stamped on the package until measures are taken to standardize dates and labels on food packaging.
