Americans waste 150,000 tons of food each day – equal to a pound per person


Research shows people with healthy diets rich in fruit and vegetables are the most wasteful and calls for better education for consumers

About 150,000 tons of food is tossed out in US households each day, equivalent to about a third of the daily calories that each American consumes. Fruit and vegetables were the most likely to be thrown out, followed by dairy and then meat.

This waste has an environmental toll, with the volume of discarded food equivalent to the yearly use of 30m acres of land, 780m pounds of pesticide and 4.2tn gallons of irrigated water. Rotting food also clogs up landfills and releases methane, a powerful greenhouse gas.

Researchers at the US Department of Agriculture analysed eight years of food data, up to 2014, to see where food is wasted and also what members of the public say they do at mealtimes. The research has been published in Plos One.

 

World’s First Road That Recharges Vehicles While Driving Opens in Sweden

(VIDEO at link)

Sweden inaugurated on Wednesday the first road of its kind that can recharge commercial and passenger car batteries while driving.

The eRoadArlanda project consists of 2 kilometers (1.2 miles) of electric rail installed on a public road outside Arlanda Airport. The innovation was funded by the Swedish Transport Administration and is part of the government’s goal of fossil fuel-free transportation infrastructure by 2030.

According to the project website, the road works by transferring energy from an electrified rail to a movable arm attached underneath the vehicle. The arm is able to detect and lower onto the electrified section when the vehicle drives above it.

The road is divided into 50-meter sections, with each section supplying power only when a vehicle is above it. When the vehicle stops, the current is disconnected. The system is also able to calculate the vehicle’s energy consumption, which enables electricity costs to be debited per vehicle and user.

A diesel-turned-electric truck owned by logistics firm PostNord is the first to use the road. Over the next 12 months, the truck will stay juiced as it shuttles deliveries between Arlanda Airport and its distribution center 12 kilometers away, The Local reported.

Try ‘Wildevore Diet’ For Healthy Living

We have all heard of vegetarian, vegan and flexitarian diets. But have you heard about wildevore diet? Surely, no! Nowadays, dieting is considered a national obsession among everyone. These types of diets mentioned above are definitely healthy and less fatty, but it might have a negative impact on one’s health and sense of well being. Concerns about climate change, environmental stress and animal welfare mean that “what we eat is an ethical as well as a health issue.”

The two women, who are promoting the all-new ‘wildevore diet’, said that the new approach will help people to show how they can eat to benefit their own health while making planet-friendly choices at the same time. The Wildevore diet incorporates some of the philosophies of veganism, vegetarianism, flexitarianism, ethical omnivorism, and clean eating, but it looks more closely at the pressures on the environment and the impact that has on human health, according to The Ecologist.

The new eating approach identifies on how to make the best choices both ‘nutritionally and ethically’ and aims at educating the people about where their food originates from. Health problems Caroline Grindrod, an environmental conservationist, writer, and Wildevore coach, and Georgia Winfield-Hayes, a nutritionist both agree that the new eating diet is not for the “faint-hearted, requiring some serious homework and a desire to change habits.”

The system can work for vegans and meat-eaters, but there is an underlying need to understand the consequences of food choices. In the Wildevore diet, meat reared on regenerative farms and fed on natural diets is allowed for its human health benefits. Georgia, who has written extensively on human nutrition, said that a vegan diet does not ‘always’ provide the best results.

‘From a health perspective a vegan diet, in the short term is an amazing way to cleanse the body and this feels great,” Georgia said. “However, long-term it can create serious health problems. Soya, the main protein source for many vegans, is a hormone-disrupting food and can cause our own reproductive systems to stop working correctly,” she added.

Coffee and Deforestation: Addressing Coffee’s Footprint

About one third of the world’s land, more than four billion hectares, is forest. Every year, this area decreases by an average of 13 million hectares, about the same size as 35 football fields per minute. The largest losses are observed in Africa and South America, mainly due to agriculture.

Coffee originates from the humid, tropical forests of Southern Ethiopia and South Sudan, and around the globe it is largely grown in many former forest landscapes,  some of which are located in biodiversity hotspots or protected areas, such as the Mata Atlântica and the Cerrado region in Brazil, the Mesoamerican Forests in Central America and the Eastern Afromontane Forests hosting the genetic diversity of Coffea Arabica in Ethiopia.

Yet the relationship between coffee and forest cover today is weakly addressed in our sector. We look at many other aspects related to sustainability in coffee: Where will future production come from if young people continue migrating from rural areas? How can productivity be increased to meet growing demand? How strongly will climate change impact production volumes, quality or specific coffee regions? Which varieties should be promoted to cope with rising temperatures and more irregular rainfall patterns? How can supply chains strengthen coffee producers in their operations?

US Electricity: Natural Gas & Coal Fall, While Renewables Continue to Rise

Electricity generation from both natural gas and coal fell in 2017. At the same time, renewables – especially hydropower, wind, and solar – continued to rise according to new data from the U.S. Energy Information Administration (EIA).

The ‘nightmare’ California flood more dangerous than a huge earthquake

California’s drought-to-deluge cycle can mask the dangers Mother Nature can have in store.

During one of the driest March-through-February time periods ever recorded in Southern California, an intense storm dumped so much rain on Montecito in January that mudflows slammed into entire rows of homes. Hundreds of homes were damaged or destroyed, and at least 21 people died.

It was a grim reminder that in a place so dry, sudden flooding can bring disaster.

Eighty years ago this month, epic storms over just six days caused widespread destruction across Southern California.

Rain fell as fast as 2 inches for a one-hour period. Wide swaths of the San Fernando Valley were inundated; floodwaters in the Los Angeles River mowed down bridges and pulled apart railroads.

Government officials responded with a major flood control campaign, building dams and deepening rivers and lining them with concrete to flush water out to sea before floodwaters could rise.

But even those protections have limits. And history shows there is precedent for even more devastation.

Several weeks of monumental storms would be all it would take to overwhelm California’s flood control system and cause widespread flooding and destruction.

Buried, altered, silenced: 4 ways government climate information has changed since Trump took office

After Donald Trump won the presidential election, hundreds of volunteers around the U.S. came together to “rescue” federal data on climate change, thought to be at risk under the new administration. “Guerilla archivists,” including ourselves, gathered to archive federal websites and preserve scientific data.

But what has happened since? Did the data vanish?

As of one year later, there has been no great purge. Federal data sets related to environmental and climate science are still accessible in the same ways they were before Trump took office.

However, in many other instances, federal agencies have tampered with information about climate change. Across agency websites, documents have disappeared, web pages have vanished and language has shifted in ways that appear to reflect the policies of the new administration.

Two groups have been keeping a watchful eye on developments. We both belong to the Environmental Data Governance Initiative, the organization behind the data rescue events. The initiative now monitors tens of thousands of federal websites with the help of specialized tracking software. In January, the group published a report that describes sweeping changes to federal web resources.

How Do Big Oil Companies Talk about Climate Science? Four Takeaways from a Day in Court

In front of a standing room only courtroom audience, the case of The People of California vs. B.P. P.L.C. et al. took an important step forward yesterday. In this case, the cities of San Francisco and Oakland, CA, are aiming to hold five major fossil fuel companies responsible for climate damages, particularly with respect to sea level rise. In a federal court in San Francisco, the presiding Judge William Alsup had specifically asked both sides to present a “tutorial on climate science” and to address eight questions he had posed. So how did the big oil company defendants present their version of climate science? And how did it compare to the scientific consensus? Together with my UCS colleague Deborah Moore, Western States Senior Campaign Manager, I was lucky enough to get a seat in the courtroom. Here are four of our takeaways from the day:

1. Judge Alsup was highly engaged with the presenters from each side

How to Escape Reality in 10 Simple Steps

Both climate science denying scientists and regular scientists are sensitive to bias, everyone is. Because of this, scientific protocol has scrutiny built-in and it’s called peer-review. It isn’t bullet-proof, but scientists publishing peer reviewed work do have more bias checks in place than consultants who use their own blog posts as references, like Curry. From the 32 references in Curry’s testimony, twelve are her own texts, two of which were published on the website of the Global Warming Policy Foundation, a UK based think tank which aims to challenge the policies envisaged by governments to mitigate anthropogenic global warming. Cognitive bias does not make the majority of climate science research untrue, it does explain in part why people are still openly questioning the reality of anthropogenic global warming, we don’t want it to be true. Facts don’t move people, stories do, and stories of uncertainty work like a powerful anesthetic, paralyzing both the public as well as policy makers. There are several coping mechanisms that kick in when facing the overwhelming threat of global warming (Hamilton, 2010). One of them is distancing. When faced with a threat of such unfathomable proportions as global warming, people distance themselves from it. There is plenty of time to fix the problem. Optimism bias gives people the idea that bad things are less likely to happen to them. Self-serving bias leads to the interpretation of information that is most beneficial. Confirmation bias creates the tendency to interpret information in a way that confirms preconceptions. When presented with conflicting information, cognitive dissonance can lead to outright denial or dismissal of the facts. And that’s just the tip of the iceberg…

#1: Cherry pick data, focusing on the unexplained or anomalous cases

#5: Aggressively disseminate the facts you’ve manufactured

#10: Play the anti-progress card
