Tips for an Eco-Friendly Passover

Mon, 03/12/2018 - 12:00am

Enriching Your Holidays

Each year more families “go green” by incorporating environmentally sound practices into their Passover celebration. Here at the Chicago Botanic Garden, we have some tips for making your holiday eco-friendly. We hope one of ways you’ll commemorate this season of renewal is to visit the Garden with your family, to see how the earth is gloriously rejuvenating itself within our 24 individual gardens and four natural areas.

Spring’s promise of renewal fits in with the Passover theme, as the story of Exodus tells how Jews were released from slavery and left Egypt, determined to renew themselves as a people. The Passover seder, centered around food and rich with symbols, is a special time for families to gather and remember by retelling the story in a traditional format (seder means “order”). But, as with so many other holidays, commercialism has encroached upon the sacred nature of Passover, which can also involve a fair amount of junk!

Green building in Israel is on the rise as architects and contractors learn to use environmentally friendly materials and techniques.

At a natural building conference in Prague this March, Israeli eco-builder and consultant Nitzan Iserovitch will share how his Back to Earth Community  teaches people across the world – including earthquake victims in Nepal – to build affordable, comfortable, durable houses using rammed earth and other local natural materials.

The shelter will be located near a 25-mile-wide, 200 million-year-old crater in southern Israel.

Fans of the 2015 movie "The Martian" starring Matt Damon got a pretty good glimpse of what it would be like to live on the Red Planet. He was forced to survive for four years on Mars' inhospitable surface – unable to breathe outside without a spacesuit and learning to grow potatoes indoors, just to name a few of the MacGyver-esque techniques he had to employ to stay alive.

Is man-made pollution making storms more severe?

Mon, 02/19/2018 - 12:00am
by Jaime Bender for FromtheGrapevine

Research shows that even the smallest of man-made particles can intensify thunderstorms, which can lead to soil erosion, runoff and damaged crops.

In case you're still wondering what kind of impact something as commonplace as your car's exhaust is having on the environment ... wonder no more.

A new study from an international team of researchers – including Dr. Jiwen Fan at the U.S. Department of Energy and Professor Daniel Rosenfeld of the Institute of Earth Sciences at Hebrew University in Jerusalem, Israel – found that even the smallest particles from man-made emissions can fuel severe storms and influence weather. That, in turn, can wreak serious havoc on crops and agriculture.

By ISRAEL21c Staff

New multinational research reveals that even small amounts of manmade aerosol particles can wreak havoc.

Even the tiniest of particles from human emissions can fuel powerful storms and influence weather and crops much more than previously thought, according to new research published January 26 in the journal Science.

The study focuses on the power of manmade aerosol emissions to grow rain clouds and intensify storms. These particles come from urban and industrial air pollution, wildfires and other sources.

New paint transforms sun’s rays into cool air-conditioning

Mon, 01/29/2018 - 12:00am
By Abigail Klein Leichman for Israel21c

SolCold’s nanotech coating is a potentially game-changing electricity-free solution for cooling buildings or equipment in intensely sunny climates.

Coating materials that protect against fire, water or extreme temperatures are nothing new. But an Israeli high-tech paint doesn’t just protect surfaces from the sun. SolCold actually uses the sun’s power to activate a cooling mechanism, effectively providing air conditioning without electricity.

You read that right: This double-layered coating absorbs the hot rays of the sun and re-emits that energy in the form of cold. The hotter the solar radiation the more the coating cools down, making SolCold’s paint a potentially game-changing electricity-free solution for intensely sunny climates such as Africa and Central and South America.

Happy Tu Bishvat, the new year for trees

Mon, 01/22/2018 - 12:00am
RUSSELL MCLENDON for MotherNatureNetwork

The ancient holiday has become like a 'Jewish Arbor Day' in modern times, bringing religious and secular observers together for ecological reflection.


This spring will mark the 142nd anniversary of Arbor Day, founded in April 1872 as a time to "plant, nurture and celebrate trees."

But long before that, another tree-centric holiday had already been promoting arboreal appreciation for centuries. Tu Bishvat — also spelled Tu B'Shvat, Tu B'Shevat or Tu BeShvat — is an ancient Jewish holiday known as the "new year for trees." Its original role was to calculate the age of fruit trees, but today it has a broader ecological tone, earning it nicknames like "Jewish Arbor Day" and even "Jewish Earth Day."

Tu Bishvat falls on Jan. 31 this year (it technically begins at sunset Jan. 30), marking one of four new years on the Jewish calendar. While many religious and secular observers honor the holiday by planting trees, it has also inspired lots of other eco-friendly traditions over the years, from sustainable seders to tree-sitting.

An Israeli company is marketing its intelligent date code labels that monitor the temp and time interval of food products on their way to consumers.

“The milk is past its expiry date. We have to throw it out.”

“No, we don’t. It smells fine.”

“But it says so right on the carton.”

It’s an argument that’s been heard in households around the world: Does the expiration date on the package really mean the milk or the chicken or the eggs are bad?

Ben-Gurion University launches company to commercialize the unique underwater vehicle for research, security, communications or military uses.

Under the surface of waterways across the globe, small remotely operated submarines are busy checking pipelines, mapping underwater minefields, taking geological and biological samples, scouting locations for communication cables, and searching for sunken vessels.

A group of 20 undergraduate and graduate engineering students from Ben-Gurion University in the Negev saw that existing autonomous underwater vehicles (AUVs) have several limitations and they worked with Prof. Hugo Guterman in BGU’s Laboratory for Autonomous Robotics (LAR) to build a better model.

MIDBAR-the Swiss Society for the Revival of Desert Areas embarks on a tour of the Negev with KKL-JNF to learn how the organization combats desertification in Israel.

Combating desertification is one of the central values KKL-JNF has championed under its banner. Friends the world over aid KKL-JNF in combating desertification, and one of the most prominent  among them is MIDBAR - the Swiss Society for the Revival of Desert Areas.

Over the past several years, MIDBAR has supported several projects including planting a grove of trees in the green belt surrounding Beersheba, plantings in the Duda’im Forest and soil conservation and tree plantings along the Karkur Stream. 

“When I see the trees grow here in the middle of the desert, I draw strength from them”, said Armand Rudolf von Rohr, CEO of MIDBAR, during a study tour of the Negev with KKL-JNF. “I believe that trees are the natural solution to global warming.”

Roots Sustainable Agricultural Technologies has one technology to stabilize plant root temps and another to irrigate farms with dew condensation.

Boaz Wachtel is best known in Israel for founding the Green Leaf (Ale Yarok) political party, which ran for Knesset several times on a platform of legalizing cannabis. Green Leaf never passed the voter threshold and Watchtel “retired” from the party in 2006. He has now transformed his passion for green into a different kind of initiative.

Wachtel is the founder of several Israeli agriculture technology companies. His latest – Roots Sustainable Agricultural Technologies – just went public on the Australian Stock Exchange, raising a modest $5 million.

Is the future of sustainable electricity ... in turkey droppings?

Mon, 12/18/2017 - 12:00am
by Jaime Bender for FromtheGrapevine 

A new study shows that poultry excrement could be used as a viable biofuel.

This time of year, we typically think of turkey as the centerpiece of a giant, hearty, all-American holiday meal.

But according to a new study, we should all be looking at it from a, um, slightly different angle.

Researchers at Ben Gurion University in Israel found that converting treated waste from turkeys, chickens and other poultry into combustible solid biomass fuel would produce an alternative energy source that's environmentally safer than coal, and could be used to replace it.

From Sustainable Baby Steps

Have you started preparing your eco-friendly Hanukkah traditions yet? No doubt you are thinking about polishing your menorah, dusting the dreidels and starting the search for the perfect presents.

However, how will you polish that menorah? Did you keep the dreidels from last year and what types of presents will you buy? These are all things which need to be taken into consideration if you want this holiday season to be a sustainable one.

My household Hanukkah traditions usually consists of a nightly Menorah lighting and present giving, so that each family member receives eight presents in total. We might also go to a public Menorah lighting and attend or hold our own Hanukkah party during the 8 day festival. We don't put up much in the way of decorations or exchange cards, but every family is different with their own Hanukkah traditions over decorations, food, present giving and so on.
