Why should a person not interfere in nature? The next story will illustrate well.
Yellowstone Park in the U.S., the world’s first national park, was known for its large, impressive wolf community that has become the park’s hallmark to this day. In the 1970s, farmers in the area began to press against the authorities for the wolves to devour their herds of grass weed for pleasure in the open fields throughout the park. Because of this, and without much thought ahead, all the wolves in the park were shot or poisoned – and in the early 1930s, they disappeared completely.
Happy ending all good for the ranchers and the park? So it’s not. Nature is stronger than anything.
Once the wolves were destroyed, a serious chain of natural events began in the park:
1. Since the wolves stopped devouring the herds, the elk population in the park has grown massively.
2. Because elk are vegetarian and at the moment there was no one to devour them, they eliminated larger areas of vegetation and, in an increased form, making green areas until then, completely arid.
3. Weeds and trees on the banks of the rivers completely disappeared and stopped growing, and as a result, there was no bird feed in the park, so the number of birds in the park dropped drastically.
4. The beavers, who feed on trees on the banks of the rivers, have disappeared … due to the simple fact that their trees and food have disappeared on the banks of the rivers.
5. Because the builders are gone, the kinds of dams they create also disappeared and there was no one to provide a cold and shaded area for fish in the park, which also diminished dramatically.
6. Due to a large amount of arid land in the rivers (there is no vegetation, no beavers, no dams, no fish, etc.), floods swept more and more soil with them.
7. Due to the flooding and erosion, the banks of the rivers were no longer stable, causing the rivers themselves to deviate from their path and endanger the (remaining) animals in the park and the access roads … even to hikers.
8. The reindeer, who no longer had to move, trampled whole fields, field after field … of the ranchers themselves!
9. Because the elk does not die, there are no actual carcasses on the ground, which means fewer eagles, crows, foxes, coyotes, and bears living in the park. Most of them have left.
10. If there are no carcasses there are also no reptiles/worms, and something that will feed the land that will re-grow as part of the natural ecosystem.
All this, of course, did not occur within a year, but slowly and steadily, until another species of strain was hit by that nonsense in the 1970s.
** Bonus Fact: There is good news – it was only to the Americans that the token fell into the 1990s. The solution? Return the wolves of course.
As mentioned in the mid-1990s, about 30 wolves were trapped in Canada (not all of them, don’t worry) and released in a controlled manner in the park.
The wolves got used to the scene, started hunting elk, who suddenly had to move. More traffic = less stay on the banks of the rivers and other vast areas = more vegetation, more trees, more animals, and more park life. The entire ecosystem is back to rebuilding.
At present, the park is still in recovery but is in a significantly better position than it was only 25 years ago.
