Waste
Go Paperless and Opt Out of Junk Mail
I will reduce the amount of paper mail that I receive by 3.4lbs (1.5kg) a month or 41lbs (18.6kg) a year by opting into paperless billing, ending unwanted subscriptions and opting out of junk mail.
Water
Understand My Water Footprint
Each of us has a water footprint, directly linked to our daily activities as well as the water required in the production of things we use each day. Understanding our water use is important for a healthy planet. I will calculate my water footprint and look for a few ways I can reduce consumption or waste, then share what I learned on the feed.
Feedback Survey
Take the Campus Ecochallenge Feedback Survey
Tell us what you thought! Take a short survey about your experience to help us improve future events. It only takes a few minutes — and when you complete the survey, you'll earn points!
Waste
Repair a Broken Item
I will repair at least one item that is broken, but is repairable. This might be items like garden tools, sewing machine, small appliances, electronics, clothing, and more.
Health
Reduce refined sugar
Cutting back on refined sugar can improve energy, mood, and overall health. I will limit my intake of sugary snacks and drinks by reducing refined sugar in meals or snacks each day.
Community
Make Sure You are Registered to Vote
I will make sure I'm registered to vote. While I'm at it, I’ll sign up to help others register too!
Energy
Calculate My Carbon Impact
Knowing our carbon footprint is the first step to reducing it. I will calculate my carbon impact and identify lifestyle changes that could reduce the carbon footprint and impacts on the environment. I will share my commitments to lowering my impact on the feed.

Calculate my Digital Carbon Footprint
I will calculate my digital carbon footprint and take steps to reduce my CO2 emissions.

Community
Engage In Active Listening
I will practice actively listening to a friend, family member, classmate, acquaintance, or someone who I may disagree with in at least 2 conversations.
Health
Prioritize Getting Enough Sleep
Good sleep is essential for a healthy body and mind. I will prioritize getting 8 hours of quality sleep each night and develop a bedtime routine that supports rest and relaxation.
Energy
Turn Off Lights and Electronics
I will keep lights, electronics, and appliances turned off when not using them.
Health
Enjoy Fruits and Veggies
Adding fruits and vegetables to our meals nourishes our body and the planet. I will prepare and enjoy 3 servings of a variety of colorful fruits and veggies.
Food
Enjoy a Meatless Meal
Producing 1 kg of beef emits as much greenhouse gas as driving 150 miles, meanwhile, 1 kg of veggies or grains leaves a much lighter footprint! This week, I’ll shrink my climate impact by having 2 meatless meals and/or 0 vegan meals each day.
Food
Try a New Way to Prepare Food
I will try a new method of food preparation, such as canning, pickling, or baking bread.
Food
Buy From a Farmers Market
I will try to shop at a farmers market or food co-op, if one is accessible, to support local farmers and businesses. By doing so, I may be able to learn more about who produces the food I eat and goods I buy.

Think About My Core Values
We may find more meaning and joy in life when our actions are aligned with our personal values. I will determine what my top 3-5 core values are so that I can better align my actions with them.
Simplicity
Replace Screen Time with Other Activities
I will replace 25 minutes of screen time each day with other activities.

REFLECTION QUESTIONWasteReducing your paper mail can reduce mental clutter as well as physical waste -- by reducing what is coming in, you can reduce what is going into the recycling bin too. How does it make you feel? What is the next step you will take to reduce your waste?
Sophie Mannewitz 9/30/2025 5:02 PMIt is very convenient because you save time and resources. same thing for emails. every email also needs electricity and takes up data space. the next thing I want to reduce waste about is plastic bags when going grocery shopping. I use my onw bags that I bring to the store -
Sophie Mannewitz 9/30/2025 4:21 PMgood so far, I have tried many new things :) -
REFLECTION QUESTIONNatureHow can spending more time outdoors enhance your sense of place -- your deep knowledge of and appreciation for your surroundings?
Sophie Mannewitz 9/30/2025 4:16 PMI don't hike in Germany. Actually, here on Hawaii I hiked for the first time! It is really good to clear your head and connect with nature. It is good that you can't really be on your phone during it, because you have to watch where you step (depends on the hike though). The hikes around here have such a beautiful view and really show you where on this island and planet you are. You can sometimes (if you're up high enough) see kind of the outline of the island and really understand where you actually are in the moment. -
REFLECTION QUESTIONSimplicityWhat did you notice in implementing this challenge? Was it hard to choose other activities over screen time? How did you decide to spend your time?
Sophie Mannewitz 9/29/2025 1:30 AMthis is quiete hard for me at the moment. I try to reduce my screen time. in Germany this worked pretty well. Here, however, it is not going so well. I should do it though, because it relaxes me, reduces my anxiety and uses less electricity because I have to charge less often -
REFLECTION QUESTIONHealthHow does eating more fruits and vegetables and less meat positively affect yourself, other people, and our planet? What fruits or vegetables did you try this week, and which was your favorite?
Sophie Mannewitz 9/29/2025 1:29 AMI ate a lot of bananas, papayas, apples and mango this week. I try to eat a lot of fruits and veggies but over here it is very expensive. but it is not only healthy for myself, it also is better for my environment such as the animals that do not get hurt in the process and less resources needed. -
REFLECTION QUESTIONNatureHow do you experience your neighborhood or city differently when walking instead of driving?
Sophie Mannewitz 9/29/2025 1:26 AMIt is a lot slower. I walk a lot in Germany. Here I used to also walk a lot. But I got a moped a couple weeks ago. Since then I walked less. However, I try not to use it if it is just a quick walk, or if the bus takes the same time -
REFLECTION QUESTIONFoodHow was your experience intentionally trying to eat less meat?
Sophie Mannewitz 9/29/2025 1:24 AMso far my expirience has been good .I usually don't eat a lot of meat, it is more dairy. I also try to cut down on that. I just have to try to eat enough protein and get enough iron in my system, because I don't eat enough of that -
REFLECTION QUESTIONEnergyHow is electricity generated where you live? How does it impact the environment, animals, and humans?
Sophie Mannewitz 9/29/2025 1:23 AMCurrently I live here on Hawaii. I live in a rental unit, where all costs are included. therefore, I don't know how the energy is produced. I germany my electricity is generated by 25% renewable wind energy. -
REFLECTION QUESTIONNatureFather Thomas Berry says, "... our primary purpose is celebration. Celebration of the dawn and the sunset and the different seasons of the year is a religious ritual, a way in which humans can establish their integral relationship with the universe, with the planet Earth." What is your response to Berry's assertion?
Sophie Mannewitz 9/25/2025 4:55 PMI don't fully agree with his statement. I don't think this would be our primary purpose. However, I think it is really healthy to connect through nature by watching a sunrise and a sunset. It also works as a natural clock. -
REFLECTION QUESTIONSimplicityDo people with economic privilege have a responsibility to consume and own less? How can the concept of “reduce” be presented to those who may be struggling to have enough food, clothes, shelter?
Sophie Mannewitz 9/25/2025 12:15 PMI think the problem of overconsumption is mainly a problem caused by priviledged people. it is not about the poor ones, struggling. It is about the excess consumption of humans that would not need to buy more. all the clothes, electronic devices, tools etc. we don't need but still buy, either because we think our life would improve by owning such things. we try to find happiness etc. in owning items. however, this usually doe not last for a long time. we buy and concume to fulfill us without asking us if we really need them or keeping in mind how much it takes to make these items or what happens after we throw it out again.
