Good News Friday (10/23/20)

Author: Camellia Moors ’22

It is admittedly easy to get caught up in the seemingly endless torrent of negative environmental news from around the globe, which can make positive actions feel pointless. In doing this, we can lose track of positive developments and, even worse, lose hope for our planet’s future. If you are in this position, welcome to our new “Good News Friday” series, which hopes to provide a breath of fresh air with some recent positive environmental news from around the world. 

Here’s a list of just some of the things that have been happening recently:

  1. Bye-Bye Ocean Plastic: It is no secret that plastics pollute our oceans, present on both the surface and the seafloor and worsened by the volumes of trash generated during the pandemic. Groups like the Ocean Voyages Institute and The Ocean Cleanup, however, have made it their mission to remove some of this pollution: the former recently removed the largest-ever haul of plastic (103 tons) from the Pacific Ocean, and the latter plans to present its first product made from collected ocean plastics later this month.

  1. Planetary Emergency: The United State’s announcement of its withdrawal from the Paris Agreement in 2017 sent shockwaves around the world, threatening future progress towards obtaining emissions goals. While that withdrawal cannot officially go into effect until November 4th of this year (one day after the election), one reason for hope for the future of global cooperation is that the leaders of 64 countries plus the European Union have acknowledged the “planetary emergency” and have pledged to undertake a variety of actions to counteract environmental degradation.

  1. Climate Cases: Litigation seems to have become a common way of targeting polluters and encouraging environmental justice in recent years. One example is an ongoing suit filed by state and local governments against the American Petroleum Institute (API) which charges that API misled consumers about the climate impacts of fossil fuels. Regardless of the case’s outcome, advocates see the act of litigation alone as providing serious leverage against big oil.

It might not seem like it, but progress, even if slow, is progress nonetheless. Here’s to hoping it gets even better!

Sustainability on a Budget!

Author: Adam Wickham ’22

While browsing social media, it may seem like you need to buy a lot of new, sustainable gadgets and gizmos in order to be environmentally friendly. However, you don’t need to go into debt in order to be sustainable! In fact, you can actually save money through some straight-forward changes in shopping, eating, cleaning, and organizational habits. As the motto goes: reduce, reuse, recycle! While we EcoReps often stress recycling, it is even better to reduce your consumption and reuse things that you’ve already consumed! Below are some tips on how you can be more sustainable on a budget:

  1. Buy seasonally (and locally)!

Eating locally doesn’t mean you have to break the bank at an upscale supermarket like Whole Foods; it just means that you are conscious of what you eat and when it’s in season. Fortunately, when something is in season, it’s generally cheaper! While farmers’ markets offer the greatest variety, local produce carts and supermarkets of immigrant communities offer good options too if they’re available in your area. 

Here are some examples from the USDA. Price and availability vary by your region. 

  1. Clean with reusable rags and easy DIY cleaning solutions

When your clothes rip or wear out, don’t throw them away! First, try fixing them (such as with Mend), but if that’s not an option consider turning them into rags. Old t-shirts work great for dusting and cleaning (and they can even be adapted as Swiffer attachments), while old socks are great for dusting smaller areas and erasing dry erase boards. You can even make a water and vinegar cleaning solution, which is cheaper than traditional cleaning products and non-toxic!

  1. Use what you’ve already got!

In an ideal world, you wouldn’t have any single-use plastics, but you probably do. So, I’d recommend finding ways to reuse plastic bottles, glass bottles, and other containers that you already have. For example, takeout containers can be used for school supplies and other small objects. Yogurt containers can make good pencil holders, while a cut-up carton could be used for potting plants or for storage. As you may realize, I enjoy storage containers. 

I hope these tips aren’t too intimidating! For those of you who may not feel that you’re making much of a difference on a macro scale, remember that you can save money and still make a sustainable dent in your own home and community. 

Got a Case of Cabin Fever?

Zoom fatigue is real, and us staying locked in quarantine doesn’t help the case. These days, it is more important than ever to prioritize mental health and stress management. It can, however, be hard to find any breathing room amidst our steadily compiling assignments and deadlines. But self-care doesn’t require fancy equipment or programs. In fact, lifting your mood and lowering anxiety can simply be done by spending time outdoors.

According to registered psychologist Dr. Lynne M. Kostiuk, “Nature…slows us down, lets us pay attention to different things, and let go of others. It gives us a chance to just enjoy ‘being’.”

Research has shown that as little as 20-30 minutes of exposure to nature a day can significantly reduce your cortisol levels, leading to a less tense and more positive mindset. Your memory and ability to focus improve, and your future self and grades will thank you. Exposure to natural light and fresh air revitalize your body, and it helps give your mind the break it needs. It doesn’t have to be a long, grand hike either – just a walk around the neighborhood will do the trick.

Got a case of cabin fever? It’s time for a change of scenery. How about taking a walk today?

It’s Hard to Be Green Right Now

Author: Wesley Wiggins ’21

This year has been collectively deemed the worst by most people around the world. With the coronavirus limiting our mobility, racial justice at the front of our minds, a foreboding presidential election around the corner, and the effects of climate change ramping up it is hard to not feel like there is too much to deal with this year. For me, this has manifested itself as a severe lack of motivation in my daily life and has crippled many habits that I have tried to form this year. This lack of motivation has also come with the feeling that I have to do more than ever because it looks like I have more free time than ever. This has caused increased feelings of disappointment in myself because I always think I can and should be doing more while ignoring the fact that I’m dealing with a tremendous amount of loss. This all results in a feedback loop that makes trying new things really difficult and at points demoralizing.

Earlier this year, I attempted to reduce my meat consumption for both ethical and sustainability reasons, and for the first few weeks, it was going well. I started limiting my meat consumption to once a week for a month in May and continued through the month of June. But at some point, I slipped up and started having meat multiple times a week. By the end of August, it was as if I had never tried to change my diet at all which led to the unforgiving cycle of beating myself up about it. But the truth is while we all have a personal responsibility to take care of the Earth that does not mean it is going to be easy or that you will get it right on the first try.

Recently, I’ve tried to take things slower by sticking to non-meat lunches and breakfast while being more conscious about what I eat for dinner. The biggest change I’ve made is not setting myself an all-or-nothing rule about what to eat and starting to look at sustainability less as a lifestyle and more as a series of choices that I can make to heal the Earth and ensure a better life for future generations.

There are a lot of systems set in place in our society that make it hard to be sustainable. Pandemic or not, we can’t beat ourselves up for slipping up. Being sustainable in our daily lives is a choice we have to make every day. Even though we slip up and make mistakes we can still look at our lives today and make a new choice to be more sustainable.

Bringing Together Algae, Food, and Compost

Author: Wesley Wiggins ’21

In the Fall 2019 semester, I worked on a project which incorporated the S.C.R.A.P. Lab (our campus composter, fondly known as Scrappy) for my class ENE321: Resource Recovery for a Circular Economy taught by Civil and Environmental Engineering Professor Z. Jason Ren. This class discussed the topic of a circular economy which is the idea that resources should be reused and repurposed instead of how our linear economy simply puts items into waste. Our final project for this course was to create a business idea and pitch for a company that incorporates elements of the circular economy, and when I first heard of this idea my mind immediately turned to compost. 

Composting takes food scraps and uses it to create a soil additive that enriches the earth which can assist in growing new food and/or keeping the environment healthy. My team also wanted to incorporate a new element and produce something from compost. Through our research, we learned that the process of composting emits biogenic CO2 and we wanted to repurpose that gas and produce something new. Our minds turned to the process of photosynthesis in which water and carbon dioxide contribute to building organic matter so we wanted to find a product that we could grow easily and then sell to consumers. This is when we came across the algae species, Arthrospira maxima and Arthrospira platensis more commonly known as Spirulina.

Spirulina (Arthrospira platensis and Arthrospira maxima) contains 55-70% protein by dry weight, as well as high amino acid content and nutrients. It grows best in environments with high CO2 concentrations, a high pH, and high temperatures.

Spirulina are a globally cultivated algae species for food production because of their high protein content and nutritional value. We decided that the nutritious algae would be an excellent food product to sell as our business product and the only thing left to decide was how to grow the spirulina. We decided that the best way to grow them and incorporate the compost would be to use a photobioreactor which is a closed system that would allow us to control the inputs and outputs of the spirulina growth mixture. We could also take the CO2 from an industrial composter like Scrappy and feed it into our photobioreactor to cultivate the spirulina.

After settling on an idea, my team had to settle on a company name and company roles. The members of my team were myself as the Chief Technological Officer, Jivahn Moradian ‘20 as the Chief Financial Officer, and Gabby D’Arcangelo ‘21 as the Chief Executive Officer. When deciding on a name we wanted something that represented both the algae and the use of carbon dioxide from the composter. So the name we settled on was AlgaeHG or AlGHG. The GHG in the title is short for Greenhouse gases which we are using to create our product in the form of CO2.

Though the company was created for a class project, the three of us had quite a fun time brainstorming the science, engineering, finances, and algae puns for our little class project. And we were thankful to Gina Talt and the S.C.R.A.P. Lab for letting Gabby and Jivahn visit the Lab during my shift, and for all of the other assistance, we were able to receive. 

Sustainable Meals for Busy Students: BBQ Portobello Burger

Author: Julia Harisay ’21

Are you cooking for yourself this semester? Are you trying to figure out how to balance all your school work and find time to cook healthy and delicious meals? Are you interested in how to do this while reducing your carbon footprint and doing something good for the planet? If you’ve answered yes to any of these questions, then you’ve come to the right place.

Try out this quick Southwest BBQ Portobello Burger recipe!

Why in the world should you ditch your juicy, delicious beef burger for a mushroom you might ask? Producing meat, especially beef, has a huge impact on the planet. From the feedstock grown to feed livestock to the methane emissions from cow farts and burps (yup, that’s the proper terminology), livestock production produces far more greenhouse gas emissions than does plant and crop production. Producing a pound of beef can produce an equivalent of 14.8 pounds of carbon dioxide, a greenhouse gas that when in excess contributes to global warming. Mushrooms? Producing a pound of mushrooms only produces an equivalent of .7 pounds of carbon dioxide. Not only are mushrooms better for the planet, they are also really good for you! Mushrooms contain a high daily percentage of key vitamins and minerals.

Still hesitant? Wondering how a mushroom can come anywhere near rivaling a burger? I promise you, you will be surprised. Follow this recipe to cook your mushrooms in a delicious barbecue marinade that is going to pack your mushroom with flavor. Not into barbecue? Swamp it out for a flavor of your choice! This recipe is easy and quick–exactly what a busy college student like you needs to satisfy your taste buds and do good for the planet and yourself.

Step 1: Preheat your oven to 475 °F. Wipe the portobello mushrooms with a damp cloth and remove the stems.

Step 2: Combine and mix the ingredients for the marinade in a bowl: ¼ cup of BBQ sauce, 2 tbsp of soy sauce, 2 tbsp of olive oil, 1 tbsp of apple cider vinegar, 1 tbsp of liquid smoke

Step 3: Dip and submerge each mushroom in the marinade and then place them gill side up on a glass baking pan. Pour the remainder of the marinade over the mushrooms and then put them in the oven to cook for 22-25 minutes.

Step 4: Prepare any other toppings you normally like on a burger: pickles, tomatoes, lettuce, onions, etc.

Step 5: Toast your buns, assemble your burger, and pair with your side of choice, such as fries. Enjoy!
