He spilled thousands of tons of orange peels to the field - 16 years later he stunned the world with the results
For decades countries all over the world have been burning their rainforests - especially in South America, where many lands have been displaced to make way for the palm oil industry.
But fortunately, there are people who do their best to save these important ecosystems, like a couple from the United States who collected huge amounts of orange peels and dumped them in Costa Rica in the late 90s.
Now, more than 20 years later, the result surprises people all over the world.
In the late 1990s, the married couple Daniel Janzen and Winnie Hallwachs of the University of Pennsylvania made a deal with an orange juice maker from Costa Rica. The couple asked the company to donate part of its land for the preservation of the area and in return the company will be able to pour the orange peels there at no cost. It was a very intriguing offer, and the company agreed.
A year later, a competing orange juice company sued the other company to stop dumping the peels in the field. The suing company claimed that the orange peels polluted the area.
By the time the first company had to stop pouring the peels there, it had dumped more than 1,000 trucks, with more than 12,000 tons of orange peels that had been spilled in the area that had previously been forested. Then the experiment was forgotten and the ground remained that way for more than a decade.
Before the experiment ended, the two American ecologists put up a sign in the field. And when they returned to the place 16 years later, they had a hard time finding that sign. They did not see it anywhere, even though they checked several times to make sure they were in the right place.
They of course were in the right place but the terrain changed completely. During these 16 years, the orange peels have shrunk and formed the foundations for a new life in the renewed space.
The rainforest has been given new life. Trees grew and became stronger, and various species of animals, including ferrets, moved to live in the area.
The ecological discovery of the two ecologists taught them an important lesson: it turns out that an area that was forested in the past can come back to life. This means that if there are more projects like this, they can slow down climate change.
Princeton University has published a research on the terrain - and not long ago, Jensen and Hallwachs were finally able to find the same sign they put there many years ago. It was covered with a lot of vegetation.
Thanks to the modest orange peels, ecologists have discovered something amazing - something that can change the face of the earth. Hopefully this will inspire more such projects in the future.
What a wonderful discovery! Please share this article if you too thought it was awesome.
