500 million years ago, 'who' has caused global warming?

Before humans, the first creatures on the bottom of the sea created a major extinction, according to research published recently in the journal Nature.

About 500 million years ago, these creatures began digging into the seabed for shelter, resulting in fossil cave traces today. The " migration" wriggled their way into the organic matter that was built up, accumulated earlier.

This creature's seemingly small act has left great consequences: turbulent oceanic sediments accelerate the collapse of organic matter, causing widespread environmental changes.

"This is similar to your back garden when you have earthworms, they will enrich nutrients and nutrients into the tree" - TS. Sebastiaan van de Velde, Liberal University Brussels (Belgium), the main author shared on The Independent. "This process consumes oxygen and produces more CO2 than usual."

Based on the remains of fossil remains, the research team judged that in the next 100 million years, great extinctions occurred with primitive inhabitants on Earth.

To test, the team conducted a mathematical model of the Earth during that period.

Dr. Benjamin Mills of the University of Leeds (UK) in charge of this content said: "When we ran the model, we were surprised at what we found. We all know that in the past, the Earth has warmed up but didn't expect the event. that is created under the animal agent ".

"Research shows that there are similarities between the first animals that appear on the planet when they unconsciously change their lives, accidentally harming them , just like the current humans affect the world" - GS. Tim Lenton at Exeter University (UK) emphasized.

When the modern world is also heating up because of the amount of carbon dioxide released into the atmosphere, scientists constantly warn humanity is undergoing a new extinction. However, the difference is only in the time scale.

"In the study, we estimate that global warming lasts about 10 million years, but in fact it is probably only a few centuries, even faster" - TS. Van de Velde said.
