Scientists found a lot of information about Anthropocene era (the latest epoch of the Earth’s evolution) by studying a lonely tree of the Sitka spruce in Campbell Island, in the middle of the ocean.
The researchers have been studying the spike in radioactive carbon in the loneliest tree from Campbell Island. Scientists admitted that the humans’ technologies are negatively impacting nature but the radioactive carbon spike that has been discovered in this Sitka spruce is due to the nuclear weaponry testings from the mid-’50s and ’60s.
“The impact that humanity’s nuclear weapons testing has had on the Earth’s atmosphere provides a global signal that unambiguously demonstrates that humans have become the major agent of change on the planet,” said Christopher Fogwill, a paleoclimatology and glaciology professor at the Keele University.
The new epoch is characterized by human-made changes
Humans are changing the planetary environment by industrialization, urbanistic development, and technology which has a negative impact on the environment.
Scientists from every corner of the world agree that we all are live a new epoch which is represented by humans impact on nature. Unfortunately, our impact on nature is negative and such changes are proven by global warming, lowered ice sheets at poles, and by the toxic materials we all use or leave behind, such as plastics, vehicles’ toxic gases, and so on.
All these will lead to more and more environmental issues.
The new epoch has been named Anthropocene and it is following the Holocene epoch. Currently, we live in the Holocene epoch but the new discoveries tend to prove that we’ve already moved to the Anthropocene epoch.
The loneliest tree in the world
Even though the Sitka tree on the Campbell Island is at 125 miles away from any other tree, it is not the loneliest one on the planet.
The “Ténéré Tree” has been an important tourist destination in the Ténéré region of the Sahara desert. It is considered the most isolated tree on the planet as it is the only tree in a 250 miles perimeter.
However, the “Ténéré Tree” is gone since the early ’70s.
The lonely tree on Campbell Island shows that humanity is living the new Anthropocene epoch, characterized by human influence on nature.
