3 years sustainability journey

Image
3 years ago, I started my sustainability journey. Today, I'm often asked as expert to support other projects, conferences etc for example with the United Nations. Although it is sometimes a challenge to keep sharing content with you daily, I will continue with 1 post a day.

#723 - Working from home instead of driving to work

Image
As I quit my job to dedicate myself full-time to sustainability, I don't have an employer to travel to. But a friend told me that she has made arrangements with her employer to work at home several days a week, so that she doesn't have to travel to work. Saves a lot of fuel!

Wastewater as a valuable resource

Image
I learned that there is a difference between #wastewater and wasted water. The way we currently use the word wastewater suits wasted water better: we get rid of water we have used. But wastewater has in contrast to wasted water a lot of value: https://medium.com/the-environment/3-reasons-why-wastewater-is-a-valuable-resource-and-shouldnt-be-wasted-9f57de2a1fc8 Wastewater should be recycled so that this valuable resource can be used (credit:  Hekla  on  Shutterstock )

#359 - Keeping razor sharp

Image
It is impossible to make a razor that is blunt sharp again, as it is only possible to sharpen one side of the blade. However, by cleaning the blade on a jeans after using it, it is possible to keep the razor sharp for longer.

Solar station in Israel

This looks very impressive. This solar station in the desert in Israel consists of many mirrors that reflect the sun to the top of the tower. The mirrors turn with the sun, so that electricity can be produced throughout the day. A great example of using #renewableenergy Loading...

It provides green electricity to the environment in high quantities! #Israel #Innovation

#722 - Buying hemp instead of cotton-based t-shirt

Image
Shortly after writing an article about hemp-based products ( https://medium.com/climate-conscious/6-ways-hemp-can-be-used-as-great-alternative-to-conventional-materials-ed1279a5d528 ), I noticed hemp-based t-shirts in a a clothes shop. Apart from buying second-hand t-shirts, I also bought two of them, as hemp is more environmentally friendly than cotton. I love the color and material! 

Zombi-ants

Image
This feels other-worldly: certain fungi can hijack ants' brains! After they have entered an ant's brain, they can manipulate it in such a way that the ant is likely to die in a position that benefits the fungus. Here it can grow, produce spores and spread itself. Incredible!

#358 - Leaving wildlife alone

Image
Close to where I live, there is a bush. I was really curious what is inside this bush to walked over there. However, I decided not to get too close to be able to leave the wildlife alone and prevent me from disturbing it.

Agave syrup as vegan sweetener

Image
This week, I learned that agave syrup is a great vegan and natural substitute for traditional sweeteners such as table sugar and honey. Funny enough, I already had some syrup in my fridge, which I bought for making bread. Now I know I can use it for my muesli as well.

#721 - Using pallets to create welcome sign

Image
On a walk, I passed a building that specializes in weddings. Just before the entrance, I saw these pallets. A very creative way to make a welcome sign!

Making the aviation industry more environmentally friendly

Image
Air transportation is an integral part of our society but harmful for the environment. That's why it's important to fly as little as possible, for example by going on holiday by train or bike instead, and make this sector more environmentally friendly: https://medium.com/the-environment/how-air-transportation-can-become-more-environmentally-friendly-2a6fccca09e1 With more airplanes in the air, it is important to make the aviation sector more environmentally friendly (credit:  Jag_cz  at  Shutterstock )

Whale poop

Image
Did you know that whales' poop is vital for oceans? Whales eat fish in the deep sea and bring nutrients such as iron and nitrogen up to the surface by pooping. This helps certain types of plankton to bloom which are eaten by other marine animals. eventually closing the loop.

#357 - Giving tree a more suitable home

Image
In 2020, I noticed a little tree in my herb garden. It is great to see how it has grown a lot since then. However, having at some point a full grown tree on that spot is not going to work. Instead of pulling it out and throwing it away, I have carefully looked for a different place. Now I hope it enjoys its new home.

German government inviting all to save energy

This picture is by the German government. It thanks for and invites everyone to save energy. Apart from serving the environment, it is urgent as reserves can't currently be replenished and a shortage in winter is expected.  ➡️100 ways to save energy: https://medium.com/the-environment/how-to-reduce-the-impact-of-increasing-energy-prices-79ef853f4c5

#720 - Buying high-quality clothes that last a long time

Image
When buying clothes, it is more environmentally friendly to buy clothes that last longer, as fewer clothes need to be produced. Fewer materials have to be used, fewer packaging, fewer shipping, less energy is needed for disposal, etc. Here you can see cycling shirt I still have!

Buildings as air-pollution-eaters

Image
Did you know that buildings can be turned into air-pollution-eaters? By adding certain microscopically small particles to the coating of buildings' walls, walls are able to decompose for example nitrogen pollutants and some chemicals. And already a thin layer makes this work! Picture adapted from  dymaxfoto  on Shutterstock

#356 - Wearing wet t-shirt to cool down instead of using fan

Image
When it gets really hot during summer, it is sometimes too hot to go out or feel good. To solve that problem, I put my t-shirt under the tap, make it completely wet and put it on again. The first few seconds are a bit cold but after that, it is lovely. It saves me a lot of energy for cooling down and I can use this trick both inside and outside.

Humor in environmental communication

Image
"That's funny!" I normally don't think of the word funny in the context of environmental issues. And yet, #humor can be used to communicate serious topics such as #climateChange. As it can also distract, I explain here how to use it effectively: https://medium.com/climate-conscious/thats-not-funny-how-to-use-humor-to-raise-climate-change-awareness-fbca0e8cb414 Humor can be effective when communicating environmental issues (credit: image by  Infinity Eight Productions ; published with permission)

#719 - Using unused radish tops to create radish pesto

Image
What a great idea: I came across a recipe to make pesto from radish leaves. These are normally leftovers for me, so I'm glad I can use them from now on.

Water level management in The Netherlands

The main airport in The Netherlands is 4 m (13 ft) below sea level! But with #climateChange, not only saltwater needs to be kept out, also freshwater kept in. And while policies made sure that the ground water level is kept low, these now needs to be changed due to drought. Loading...

#355 - Filling in questionnaire for my city about sustainable future

Image
I got a letter from my city to ask me to fill in a questionnaire about all kind of initiatives they plan to do, in order to make the city’s future more sustainable. I of course support such initiatives so filled in the questionnaire right away.

How cashew nuts grow

Image
Do you know how cashew nuts grow? I for a long time didn't know and only recently learned that they grow with some kind of apple. Attached to this apple is a shell, and in this shell is the cashew nut. As nature makes a huge effort, I appreciate these nuts even more!

#718 - Refraining from importing seeds to prevent invasive species and pests to grown

Image
Invasive species can affect ecosystems and harm the environment. That is why it is important not to bring any seeds when traveling abroad. This sign at the airport points this out, and I obliged happily. 

Example of misinformation: bulk fake experts and magnified minority fallacy

Image
To me this World Climate Declaration sounds like the magnified minority fallacy and bulk fake expert fallacies, two forms of  misinformation : ***Magnified minority fallacy*** The article says that over 1,100 experts signed a declaration that there is no climate emergency. But how many scientists and professionals have NOT signed it because they disagree? If for example 110.000 experts did NOT sign it because they disagree, 1.100 sounds like a lot, but it is only 1%. Unfortunately, the number of experts asked is not mentioned (if you saw it, please let me know). ***Bulk fake expert fallacies*** The article says that 1,100 scientists and professionals have signed the declaration. But are they scientists and professionals in the field of climate change? Due to time limitation, I didn't check the whole list, but chose two random names. This is what I found: - Benoît Rittaud is a mathematician, who hasn't recently published about climate change related topics (his publication list...

#354 - Creating bunch of flowers from old book

Image
A few years ago, I learned how to fold such paper flowers. I used to use square pieces of paper that I bought in a shop. But this time, I preferred to make them from paper that I reused. That’s why I chose an old book and cut squares out of the pages.

Measuring pollution with biomarkers

Image
As pollution is becoming more common, it is important to know the impact on ecosystems. This can be analyzed using so-called biomarkers. For example, pollution can be indirectly assessed by measuring how animals change due to pollutants.

#717 - Using waiting time to walk around to find working dispenser

Image
On my journey back from Thailand, I had to wait at the airport for a while. As I had to drink all my water before the security check, I used the remaining time to look for a fountain to refill my bottle, instead of buying a plastic bottle.

Nature is our friend, our teacher, our ally

Nature is often an inspiration. Maybe flies and #octopuses for sure: https://medium.com/the-environment/3-eye-popping-characteristics-of-octopuses-that-inspire-modern-technology-19931a9e42ef . This is one reason #nature is our friend, buddy, teacher, lover, ally, you name it. Do you care well for your friend, lover, etc? If yes, does it makes sense to care for nature too? Loading...

#353 - Reusing frame for new piece of art

Image
When I rescued the frame from being disposed (#303), I didn’t like it that much after all. Therefore, I decided to use it for a new piece of art. For that, I first painted it white.

Why is living environmentally friendly so easy?

Image
Before I share my experience on this, I would love to hear from you: Why is it so easy to live environmentally friendly? I'm looking forward to hear your point of view in the comments. Thank you!

#716 - Using washable instead of one-way tray cloth

Image
I noticed this in a hotel that they used a washable cloths on the tray, instead of a single-use paper cloth. This is great, as I guess they use many of these cloths each day.

Fake steak: 3D printed meat

Image
I believe that we have all the technology and knowledge needed to move forward faster towards a healthier planet, and that only our psychology slows down our progress. For example, we are even able to 3D print a fake steak to reduce the negative environmental impact of the livestock sector! They can be made from cells grown in the lab meat byproducts plant based materials or insect based materials. If we can do that, we can believe in ourselves that we are able to sort out the rest as well. Making a positive difference every single day by taking action is a good start.

Why wait for others?

I love how @environment_go puts it, which is similar to my motto "a better world starts with yourself".

#352 - Emptying bin earlier so that it doesn't need to be cleaned as often

Image
Sometimes, I’m a bit lazy and bring the food waste to the compost bin (#156) a bit late. In that case, the bin has become dirty and I need to clean it. By now bringing the food out earlier, the bin remains cleaner, which saves water and soap for cleaning.

#715 - Replacing head of dish brush instead of whole brush

Image
When I noticed that the head of my dish brush needed replacement urgently, I remembered that I bought this brush because I can replace the head. And indeed, I found a new head, which means I reduce waste.

Recycling explanation

On my way to Thailand for the Water and Waste management conference 2 months ago, I saw this video at the airport. As Germany does a lot of recycling, which is not always easy straight away, I love it that they help travelers find the right bin.

#351 - Cleaning staircase during the day using daylight

Image
Whenever I have to clean the staircase, I make sure that I do so during the day, so that there is still daylight. This prevents me from having to use the lights.

Climate change misinformation

Image
Some climate change messages give me a feeling that something isn't quite right. This happens when the message contains misinformation based on for example logical fallacies, fake experts, conspiracy theories, and impossible expectations. As misinformation is harmful for how we see the current environmental crisis and whether we take action, it is important to recognize and counter this misinformation.

#714 - Bringing pills back to pharmacy for correct disposal

Image
A while ago, I learned about a campaign to inspire each and everyone of us to bring outdated or unused pills back to the pharmacy. By doing so, they can be disposed of properly. Otherwise they can for example pollute water. 

Making a difference for others and nature

#350 - Using paper that came in box and crafting-tape leftovers for wrapping

Image
I received a box that had paper in it to prevent the contents from being damaged and found out that I can use it to wrap presents. And as tape, I used some pieces that were left from crafting.

#713 - Making credit card case from milk cartons instead of getting plastic one from bank

Image
To protect my credit card from bending, I needed a case. Instead of going to the bank to get a plastic one, I created one from the bottoms of two mild cartons. With tape I connected these parts and made the case even stronger. I think the result is great (I'm aware that that is probably because I made it myself, not because it looks so great :) ).

“why isn’t anyone doing anything?” vs "what is stopping me from doing more?"

Image
I often hear “why isn’t anyone doing anything?” and "we must start to act now". Apart from being incorrect (I'm already taking action every day) I prefer to ask "what is stopping me from doing more?" and “how can I act now?” as I believe "a better world starts with yourself"

The importance of sponges on coral reefs

Image
Coral reefs are at risk due to climate change, so we often think about the importance of coral. But did you know that sponges on these reefs are doing an awesome job too? They for example recycle carbon and nitrogen, and remove pollution.

#349 - Bringing own shopping bag or trolley to shop

Image
When I go shopping, I bring my own bag instead of buying a new one. I’ve been using the trolley for example already for years, which has saved me a huge pile of bags.

Walking forest

In a Dutch city, the urban forest is walking, being driven around to different places in the city. A great way for citizens to experience #nature more!

Old glass can be used for many more purposes than creating new glass (Learn more:  https://medium.com/the-environment/7-alternative-ways-to-recycle-glass-waste-7b308b3eb117 ). One of the ways is to create mosaic in for example a pavement stone.

Watering bags for trees

Image
Yesterday, I saw this tree with bags around it. If found out that they are watering bags. They water the tree for 6-9 hours through tiny holes, to prevent it from dying due to climate change. And watering like this is more effective than using a watering can. Great idea!

#348 - Doing dishes by hand instead of using dishwasher

I have learned that doing the dishes by hand requires – with the right habits – less energy and water. That’s why I’ve done it by hand.

How plastic affects aquatic organisms

#711 - Eating insect based products for proteins instead of eating livestock meat

#347 - Removing old emails

Image
By removing a lot of old emails, I save storage capacity. But also, when I make a backup from my hard drive, it saves time and energy as all these old emails don’t need to be transferred.
