Food Waste: Economic and Environmental Issue

Ron Nixon talks in This article about how there is an excessive amount of food waste all over the world and that we need to not only find a better way to recycle it, but to avoid having so much waste in the first place.

Production of food has major impacts on the environment. It requires large amounts of water, fertilizer, and land. Fuel is also burned in order to process, refrigerate, and transport the food.

There are 60 million metric tons of food wasted and 32 million metric tons end up in landfills.

[(32 million metric tons in landfills)/(60 million metric tons of total food waste)] x 100 = 53%

Over half of food waste ends up in landfills. That being said, food waste in landfills accounts for 3.3 billion metric tons of greenhouse gases- which is about 7% of emissions.

There have been movements in some major US cities towards reducing food waste that ends up in landfills, but supplying grants to restaurants who take initiative to recycle their waste at the end of the night.

Reducing food waste 20-50% could save up to $120-300 billion dollars by 2030. So the question is why is it so hard to recycle food? If we want to live a sustainable life, we need to find the balance between a sustainable amount of food and wht is just too much.

What Can Save the Rainforest?

OLD CELL PHONES!

This is actually a really cool TED talk, given by Topher White.

According to White, it’s hard to hear anything that goes on in the rainforest this explains why there is so much illegal logging going on that isn’t heard and then isn’t able to be stopped.

I really just like that this idea is so simple. It recycles old cell phones and uses the cell phone signals that are already there in order to stop the illegal logging. The design White uses is also inventive in that it takes into consideration the movement of the sun and the leaves of the trees.

Just think about all he other inventions we can create using recycled materials…

 

Is the Growth of Renewable Energy Fast Enough?

Renewable energy is not on the rise, it is on the fast track. In 2014, worldwide investment in renewable energy was $270.2 billion- as seen in the graph below, a 17% increase from the previous year:

solar investment: [($149.6 billion)/($270.2 billion)] x 100 = 55 % of total investment

wind investment: [($99.5 billion)/($270.2 billion)] x 100 = 36 % of total investment

WInd and solar are leaving every other category of renewable energy in the dust as this past year they made up 91% of investments. There is progress in that renewable energy was up from 8.5% in 2013 to 9.1% of total world energy generation, in 2014. But as great as the progress is, this article, makes it clear that renewable energy has nothing on fossil energy.

“The study notes that the International Energy Agency has outlined a “450 scenario” in which the world limits carbon dioxide concentrations in the atmosphere to 450 parts per million ” and being able to stay below 2 degrees Celsius of warming, but even with the current trends, there isn’t much hope that we will be able to put off crossing over the 450 threshold.

It’s going to take a lot more investing in renewable resources and policy implementations in order for us to prevent the world from heating up 2 degrees Celsius.

The Push for [Environmentally Friendly] Kush

The legalization of Marijuana is a hot issue today. Many states have approved the use of Medical marijuana, and a few have now allowed limited personal possession, as well as the option to apply for a license to produce and sell. Now that businesses, in approving states, are producing Marijuana, the industry is starting to emerge, and will only continue to grow in years to come. See the graph below:

CANNABIS

 

This is where there is a problem with sustainability. Indoor Marijuana growth is favored in the industry, but it uses an astonishing amount of energy. This article, outlines Gina Warren’s paper, “Regulating Pot to Save the Polar Bear: Energy and Climate Impacts of the Marijuana Industry,” which will be in the Columbia Journal of Environmental Law, as well as a 2012 Study of the “Carbon Footprint of Indoor Cannabis Production.” Indoor cannabis production “uses $6 billion worth of electricity every year- which is 1% of overall US electricity.” The reason production uses so much energy is because of certain techniques needed to be performed on the plant.

1 kilogram of final product = 4,600 kg Carbon Dioxide emissions

With the industry predicted to boom in the near-future, we cannot afford for it to be increasing our CO emissions. Just think if Marijuana grows 20% like predicted from the graph in the next year, so will CO emissions and it’s not just from indoor production, outdoor production has an effect on the other plants growing in the area- not to mention producers wanting to clear forests and natural lands for production space.  Politically we are all divided on the issue of legalizing Marijuana, but one thing that can bring us together is the evident need for implementing environmental protections with regards to Cannabis production. If we are going to make sure that every other industry old and new- in the US is going green then it is only fair we do the same for marijuana. Just think how easy environmental protection laws would be to regulate since the industry is so new, that it has to be regulated anyhow!

Automatic Bill Payments are Driving Your Energy Usage Up the Wall

Today we are all overly attached to our smartphones and simply have no time for anything. Automatic Bill payment is on the rise in today’s technologically savvy society. It’s simple, it’s easy, it’s effortless, it’s driving up your energy consumption, AND omitting Carbon Dioxide into the atmosphere!

According to this article by Chris Mooney, many people who partake in automatic bill payments are sent reports that compare their energy usage levels with others around them, as well as making them aware of their unnoticed energy-wasting habits. It’s because of these reports and awareness programs that you actually end up using more energy; and because your payments are automatic, you probably don’t regularly check how much your being billed.

In this article it has a few quotes from Economist, Steve Sexton, Duke University, and a study that he has done with regards to the effects of automatic bill payment. Sexton found that “in 2010, automatic bill pay led to an estimated $1.8 billion in bills and 8.6 million metric tons of carbon dioxide emitted into the atmosphere which is equivalent to the annual consumption of 1.5 typical American houses.”

So this means:

[($1.82 billion in extra bills due to automatic bill payment)/(8.6 million metric tons of CO emitted die to automatic bill payment)] = $211.62

So for every additional $211.62 spent die to extra energy costs, 1 metric ton of CO is emitted into the atmosphere.

It’s not that we need to stop automatic bill payment all together, but that we need to be smart about it. We should all be aware of our daily energy usage and should check to make sure we aren’t increasing it causing an increased bill payment.

Water you Doing? Don’t be Stupid!

Tons of Americans are spending way more a month on their water bills than they should be NOT TO MENTION wasting millions trillions of gallons of water due to small leaks around the house. According to this article, we need to start taking initiative and fix our leaks!

1 faucet leaking per minute = 34 wasted gallons of water per year

BUT a normal faucet leaks 10 times per minute which then equals 526 wasted gallons of water per year

34 wasted gallons of water x 1 million homes with leaky faucets = 34 million gallons of water wasted a year

1 running toilet = 1,000 – 4,000 wasted gallons of water per day

lawn sprinkler systems with leaks = 6,300 wasted gallons of water each month

If you’re just an average homeowner who thinks that a leaky faucet, running toilet, or leaky sprinkler system are just no big deal, here’s how much water you’d be wasting a week:

Faucet: [(526 wasted gallons water per year per 10 leaks per minute)/(525,949 minutes per year] = 0.001 wasted gallons water per minute x 10,080 minutes per week = 10.08 wasted gallons of water per week

Toilet: 1,000 wasted gallons water per day x 7 days a week = 7,000 wasted gallons of water per week

Lawn system: [(6,300 wasted gallons water per month)/(4 weeks per month)] = 1,575 wasted gallons of water per week.

Total wasted gallons of water per week = 10.08 + 7,000 + 1,575 = 8, 585.08 gallons

Just by having what you would assume to be small leaks, are actually costing you close to 9,000 gallons of water, and your money, all going down the drain. That is too high. Granted, you might not have all 3 leaking at the same time, but still, they are all simple fixes that cost you or money down the road. We should all support the EPA in their “Fix A Leak” campaign especially now when some places in California are in a serious drought.

Safe Sex is Great Sex… the Push for Green Condoms

More than 5 billion condoms are sold each year. In fact, it was estimated that in 2005, 10.4 billion condoms were used world-wide. As you can see by the graph below, condom usage has been increasing over the years:

CONDOM

 

[Amongst males it has grown 66 – 54 = 12 % and females it has grown 53 – 38 = 15 %]

We’ve all grown up learning of safe sex practices and that condoms not only prevent pregnancies, but also against most STI’s. That being said, condoms are not biodegradable, cannot be flushed as they don’t disintegrate in water, and cannot be recycled. Condoms are taking up a decent portion of our landfills.

That being said, the positive effects of condoms outweigh the piles sitting in landfills. The biggest impact they’ve had is allowing the environmental revolution to be possible as the simplest form of birth control. Birth Control not only helps to keep the population at bay, but it reduces unplanned pregnancies which allow women wo aren’t in the position to be a mother, have a career or finish school.

Another way condoms are environmentally friendly is that they actually help save the Rainforest! According to the Rainforest-Alliance, cattle ranchers and rubber trappers disagree over rights to clear forest land. Rubber tapping is a completely sustainable practice and many countries in the Amazon, like Brazil, have sectioned off specific areas for rubber trappers to have that cannot be cut down, which is great seeing as 75% of Brazil’s Carbon Dioxide emissions came from deforestation.

according to this article, rubber trees can be harvested for 25 years or more and a high grade tree yields about 30 pounds of rubber a year. According to NPR, a tree can produce about 100,000 condoms.

This means that:

[(100,000 condoms produced by one tree)/(25 years of production)] = 4, 000 condoms produced a year per tree.

This brings us to the green condom. Many companies are starting to market a ‘Green Condom.’ For some companies this means using independent factories that were built specifically to use latex from rubber trees in the rainforests, for others it means less chemicals in condoms in order to, hopefully, find a way to have them biodegrade, or maybe even just a more eco-friendly package. Either way, according to Forbes, with the wy our society is starting to lean towards wanting everything in our lives to be as sustainable and ‘green’ as possible, it is a smart move for those ‘green’ condom companies to enter into this $1 billion-dollar-a-year market.

I think that it is smart for these smaller companies to be coming into the market with greener ways for safe sex. We all look for what is most sustainable, whether it be a reusable water bottle, or an electric car- why can’t we be green in every aspect of our lives? As a society we are all quick to talk about the next green thing- so why can’t we talk about the next generation of green condoms too? Especially since they bring awareness to saving the Rainforest!

 

Drive Less. Fly More?

With improvements in both automobile and airplanes with regards to energy efficiency, depending on circumstances, it might just be better to fly than drive to your next vacation destination.

According to this link, driving today is considered to be more energy intensive than flying; defining energy intensity as ‘the amount of energy needed to transport one person a given distance.’ So, yes, technically speaking since an airplane transports so many more people than a car, it is less harmful proportionally to the environment.

Michael Sivak found that, in 2012, the energy intensity of driving a vehicle was 4, 211 BTU per person mile, whereas flying domestically was 2,033 BTU per person mile.

Let’s put this in terms we can all understand:

1 BTU = 1,055.0558 joules

[(4211 BTU)/(person∙mile) x (1055.05585 joules)/(1 BTU)] = 4,442,840.184 joules per person∙mile

[(4211 BTU)/(person∙mile) x (1055.05585 joules)/(1 BTU)] =4,442,840.184 joules per person∙mile

*Note that a 100 watt incandescent light bulb uses 360,000.0 joules in an hour- just so you have something to reference.

[(airplane/vehicle)] = [(2033 BTU per person per mile)/(4211 BTU per person per mile)] = 0.48 which is about 0.50 = (1/2)

The energy intensive per person per mile of an airplane is half of that of a car.

Does this mean flying is always going to be more energy efficient? definitely not, but this goes to show that flying isn’t as horrible for the environment that we once all believed. Next time you think about traveling, think about how many people you’re going to be traveling with, with gas mileage the car you will be taking has per gallon, and compare that to if you were to fly. But don’t forget to factor in your own personal comfort!

Hey! My name is Rachel and I’m a sophomore from about 15 minutes south of Washington, DC, majoring in Political Science with a minor in Energy, Environmental, and Mineral Economics. I’m 0135b2c5b36f2711d3048ca81cb3e29aeb9871a17etaking this class, like most of you all, to satisfy a GQ, but also because the topic is genuinely something that I am interested in. When I was a sophomore in high school I was required to participate in my school’s science fair and when looking for a project idea, I stumbled on one relating to the resilience of certain ecosystems. Ever since then I’ve been overly interested in the environment and sustainability and it’s led me to various internship programs and even to a Youth Environmental Conference in Costa Rica where I was given the opportunity to give a presentation to Al Gore. What I understand of sustainability and resilience is that they are both a measure of strength. I think that resilience is a beautiful, naturally occurring process and sustainability is something that we can help attribute to.

I love watching TED talks and here is a pretty cool one on environmental folklore with regards to humans and their decisions and then what impact those decisions have.
