A research shows that human have crossed four out of nine planetary boundaries. The human actions are damaging the environment at unusual level from the last 11,700 years. Currently, humans are moving beyond the biophysical boundaries that facilitate the existence of human beings on Earth.
Steve Carpenter, a professor of zoology at the University Wisconsin-Madison states that it’s time to disrupt these actions. Presently, the level of carbon dioxide in the atmosphere, annihilation of species, large quantity of nitrogen and phosphorus is at its peak.
A group of 18 researchers closely examined the alterations in the Earth. The experts found that the changes on the Earth pushing the human civilization a step closer to the doomsday. They have accelerated to a great extent in the last few decades.
Additionally, the research discloses that the nitrogen and phosphorous cycles is the most affect one. So far, it has transformed up to 200 to 300 percent. In comparison, the carbon level has merely climbed up to 10 to 20 percent.
Nitrogen and phosphorus are widely used for the purpose of fertilization. The high usage of these chemical are reducing the amount of water on earth. Hence, it is essential to take strong measures to ensure the availability of food and water on Earth
Sarah Cornell, the co-author of the study asserts that humans have not completely broken the Earth. However, they are making it a difficult planet to survive on.
The research printed in Thursday’s edition of Journal science shed light on the dark future of Earth.
