The Japanese car company, Toyota, has recently announced new plans to be more environmentally conscious. 

To start, they are building a power plant, opening in 2020, that will produce clean energy from cow manure. The project is known as the Tri-Gen Project and will be located in Long Beach, CA. According to Science Alert, the plant is expected to power 2,350 homes and fuel 1,500 hydrogen-powered vehicles daily. The facility will also have one of the largest hydrogen fueling stations in the world.

Toyota made plans to stop producing cars with internal combustion engines by 2040.  And by 2050, they plan to reduce vehicles carbon emissions by 90%. The website and press release go over 4 more goals to better the companies environmentally friendly business.

Scott Pruitt has also expressed interest, publicly, in partnering with Toyota. This will be the first alliance since the lawsuit of 2003 when the EPA sued Toyota for violations of the Clean Air Act. The new partnership is being actively discourage by the Environmental Working Group. The EWG is a non-profit organization that has been a large player in creating federal environmental policies. Ken Cook, the President of EWG, sent a detailed letter to James Lentz , the CEO of Toyota, expressing concerns about the alliance. His biggest concern is Pruitt’s new 30% budget cut and feels Pruitt’s presence in the EPA will cause more harm than good.

For now, the EPA and EWG both agree that Toyota’s new environmentally friendly goals are a step in the right direction.

Waste not: Saving the environment by saving food

As the holidays draw near, most consumers are preoccupied with gift-buying and family preparations. Solid waste specialist Noelle Bowman, however, wants people to be mindful of their food waste as well.

Food waste is an enormous problem in the United States. Around 125 billion pounds of food scraps are discarded in the US per year, accounting for roughly 40% of all food waste worldwide.  Equally surprising, around 1 in 7 US citizens are food insecure.

The United States Environmental Protection Agency has a “Food Recovery Hierarchy”; a pyramid chart illustrating the different tiers of important steps to take in order to reduce overall food waste. Source reduction is the first and primary goal; a large amount of food waste starts at the harvest and at mishandled inventory.

A study on food waste increase in Singapore gave tips to consumers looking to reduce food waste by buying only what they will use, storing or freezing food for later use, and composting any unusable ingredients they can.

A rise in Bitcoin’s value could lead to an energy crisis

Bitcoin is a type of digital currency or “digital wallet.” It is used like regular money to transfer funds and generate currency but without a central bank. Over the last week, Bitcoin’s value has gone from less than $1,000 to $17,000. 1 Bitcoin is currently equal to 17,793 U.S. dollars. The money was originally viewed as “dirty,” being used for black market items. However this recent surge has sparked interest from mainline investors and bitcoin is looking to be worth millions more in the next month.

Bitcoin is run through data mines which are essentially large rooms of computers running an algorithm to code each transaction. The problem is the 32 terawatts of energy bitcoin will use every year. That much energy has the ability to power 3 million U.S. households; compared to Visa transactions, that only uses enough energy to power 50,000 American homes. According to the Bitcoin Energy Consumption Index, bitcoin could use enough energy to power all of the U.S. by 2019.

More than half of the Bitcoin “mining pools” are run out of China. Most the energy produced in China comes from coal firepower plants which has the potential to increase smog and pollution in the near by areas. 

On The Radio – United Nations Environment Programme seeks to tackle air pollution

This week’s On The Radio segment discusses how the United Nations released an anthology with suggested methods for reducing pollution worldwide. 

Transcript: As global pollution increases, action is needed now more than ever. 

This is the Iowa Environmental Focus. 

United Nations Environment Programme recently released The Executive Director’s Report: Towards A Pollution-Free Planet, an anthology that pulls environmental data from every continent and suggests general methods for reducing pollution globally. 

The report suggests that nobody is free from the effects of global pollution. Around one in four deaths globally are caused by environmental degradation, and governments must take action to reduce pollution in all its forms if they want to reduce the negative side effects of a damaged environment. 

Every aspect of global environmental damage must be examined and monitored, from waste disposal to the burning of fossil fuels. The people most effected by pollution are working class laborers in cities, since around 80% of big cities internationally do not meet the UN standards for clean air. 

Children, elderly and other vulnerable populations are disproportionately affected by air pollution. 

The statistics are sobering, but the report suggests that with better government control and a serious approach to pollution, we can all work together to better the environment and our health.

Gov. Brown declares state of emergency in California

While it is continuing to get colder in Iowa, California is having the exact opposite problem. On December 5th, Governor Jerry Brown declared a state of emergency for Southern California. Fires are currently burning in Los Angeles, Ventura, San Bernardino, and San Diego counties. More than 200,000 residents from Los Angeles and Venture counties are currently being evacuated from their homes. So far this fire season over 400 homes have been damaged. The fires are approximated to be about 20% contained as of a report from 5pm yesterday. Firefighters and police are working hard but out of state help is still being called in.

The biggest concern is the wind, known by locals as the Santa Anas. The wind is fast, dry, and making it nearly impossible to control the fires. It can blow anywhere from 50 to 110mph. Chief Daniel Berlant, assistant deputy director the California Department of Forestry and Fire Protection, said, “Stopping a fire when wind is 50, 60, 70 miles per hour is almost not possible. These fires burn into anything that’s in their path. A wind-driven fire is like a freight train, and stopping a freight train on a dime doesn’t happen.”

The debate about the environmental friendliness of Christmas trees continues

Natalia Welzenbach-Marcu | December 7, 2017

Here’s a dilemma that’s common among Christmas-observing households around the holidays: Real tree or artificial tree?

The question goes a little further than skin-deep. There has long been a debate about the safety and eco-friendliness of the real tree versus the artificial tree, with parties on both sides presenting evidence for their claims. The goal, overall, is to figure out which one leaves a smaller carbon footprint–is it the fake tree, the one that you buy once and haul out of your closet every year for a decade, thus saving on transportation costs for the real tree? Or is it the real thing, a true Christmas pine tree, an all-natural, biodegradable organism that won’t be left in a landfill?

The numbers are tricky because they’re variable. A lot of the measurements depend on how the real tree was transported to a store or warehouse, how much fuel that took, how eco-friendly the harvesting process for real trees is. Fake tree fans usually make an interesting point: with a fake tree, you save literally a decade’s worth of production.

Real tree enthusiasts have their own retort: artificial trees are plastic. PVC plastic, actually. They are definitely reusable, but once they’re discarded, they end up in landfills and in the ecosystem with other bits of equally dangerous trash that will take years and years to break down properly. Most artificial trees are imported from China, but a consumer can more easily pick local businesses when searching for a real tree.

There is a general consensus that both options have their advantages and disadvantages. Whatever decision a consumer makes, researching before a purchase is one of the best ways to give back to the Earth this holiday season.

 

 

Record highs in Iowa track with global highs

Temperatures reached an all-time high of 69 degrees Fahrenheit in Des Moines on Monday.

Iowa Mesonet found that temperatures at 8 AM and 12 PM on Monday also reached an all-time hourly high for the state on the 131 year record. A cold front swept across the state Monday night, causing temperature highs to drop to 40 degrees Fahrenheit in Des Moines on Tuesday.

There are a couple of months left in 2017, but the year is expected to be the second or third warmest year on record. The World Meteorological Organization announced on November 3rd at the United Nations climate change conference that average temperatures from January through September 2017 were 1.98 degrees Fahrenheit higher than preindustrial levels. In fact, the five year period from 2013 through 2017 is expected to be the warmest five year period on WMO’s record.

Record high temperatures have come with an uptick of catastrophic weather events worldwide. WMO Secretary-General Petteri Taalas said in the statement, “We have witnessed extraordinary weather, including temperatures topping 50 degrees Celsius [122 degrees F] in Asia, record-breaking hurricanes in rapid succession in the Caribbean and Atlantic reaching as far as Ireland, devastating monsoon flooding affecting many millions of people and a relentless drought in East Africa.”

Temperatures in December and January will determine whether 2017 is the second or third warmest year on record.
