Kurtis Baute left her homemade greenhouse just over 14 hours after being locked up.
A cloudy day resulted in a faster than expected increase in carbon dioxide levels, creating a dangerous environment for Youtuber, based in Vancouver.
"The air is very thick," said Baute an hour before leaving the confines of the cube, built on his brother's property in Courtenay. "I do not feel at my high energy normal, spiritual me. I feel a bit stupid.
Baute registered Wednesday in the hermetically sealed 1,000 cubic feet at midnight Wednesday to raise public awareness and launch a discussion on the effects of climate change.
With a master's degree in science, Baute has always been pbadionate about the environment and this experiment was supposed to be a small example of what is happening on Earth today.
The biodome was filled with more than 200 plants to produce oxygen, including sunflowers, corn and conifers. Throughout the experiment, Baute has measured the levels of oxygen and CO2 in the cube to determine how long he could stay safe inside.
Through his calculations, Baute estimated that he would be able to stay in the biodome for 21 hours, but added that there were so many variables that it was difficult to predict. However, the lack of sunshine was perhaps his biggest problem.
"Sunlight is essential for photosynthesis of plants. Without photosynthesis, plants do not absorb carbon dioxide and do not release a lot of oxygen, "he said. "Without photosynthesis, they will really compete for oxygen."
So cloudy today that the CO2 of my breath is slowly accumulating all day long. The plants have not had the opportunity to help me. Come to my abortion values on #KurtisInAJar pic.twitter.com/u8puZLiogn

Mark Van Eijk, a friend and ambulance driver from Baute, was on hand to make sure everything was going well during the experiment.
An hour before Baute leaves the biodome, Van Eijk said measuring CO2 and oxygen levels is essential because it can be hard to tell when levels are too high. In the case of Baute, its oxygen levels were correct, but CO2 levels were of concern.
"As for re-oxygenation … all it needs is to go out and take a few big sips of air and really exhale. Once he's breathing out of the surface, he should be fine, "Van Eijk said.
Baute's "abandonment level" of CO2 was 10,000 parts per million, which was achieved shortly after 14 hours. Wednesday.

"My problem with carbon dioxide is a slightly different and much smaller example of what is happening around the world," he said.
To put things into perspective, Baute indicates that the Earth's atmosphere currently contains 400 ppm of CO2, or 500 ppm in urban areas, compared to 300 ppm 60 years ago.
"It's 0.04% of the air – it's a tiny amount, but a slight increase makes all the difference," he said.
Although Baute followed oxygen and CO2 levels night and day, the real reason for the experiment was to involve people on the subject of climate change and to inspire the changes. of lifestyle.
"There are tons of data, and scientists know and agree that climate change is happening and that it is caused by humans. I do not need to contribute to this dataset with any experience I have made in my garden. But I hope that I will be able to engage people and convince them to change their way of life.
"We have to eat less meat, we have to drive less and we have to vote and we have to have conversations about [climate change]. "
Baute has documented his experiences and will publish his videos on his YouTube channel of the same name.
