Astrophysicist Neil deGrasse Tyson’s Earth Day Post tells us why “Save Earth” is a meaningless rally appeal.
On Sunday on Earth Day, famous scientists corrected a popular sentence on Twitter.
The perennial cry to “Save Earth” is odd. Planet Earth survives massive asteroid strikes — it’ll survive anything we throw at it. But Life on Earth will not.
Tyson has one thing. Planet Earth remained strong after 4.5 billion years, adapting to natural disasters, that is, destroying entire species and fauna (RIP dinosaurs) before any aliens existed.
Despite major threats in their lives, the Earth is still very resilient and adaptable. Although scientists predict that any life on earth will eventually be predicted in various ways, Tyson said that this is the current need for saving on Earth. s life.
Scientists generally believe that the Earth has experienced five mass extinctions and is currently undergoing the sixth mass extinction.
The difference between this time and the first five times is that human beings are causing the recent extinction.
As planetary scientist Carolyn Porco said on Twitter: “Save the Earth” is to save the oceans and the surface environment and the simplification of all life on earth. “
A better (and almost as pithy) slogan would be "Save our Earth" – the one with the current coastlines, biosphere, atmospheric composition and inhabitants. @aaronhuertas @carolynporco @AdamFrank4 https://t.co/PyHhMU3HXt

Science communications expert Aaron Huertas also weighed in on the catchy environmental slogans. “Admittedly, ‘Preserve the Relatively Stable Biosphere in Which Human Civilization Developed’ doesn’t quite have the same ring to it,” he tweeted.
Because right now Earth could survive for at least five billion more years when the sun’s torch finally snuffs out — short of a major catastrophic event before that, like a volcanic apocalypse or another asteroid clobbering.
Humans could potentially last another one billion years before the sun becomes too hot for life on Earth to be habitable, reported Science X.
But to make it that far, people would have to mitigate the risk factors that are accelerating the destruction of human civilization.
Those risk factors include habitat destruction, unchecked population growth, and economic activities that contribute to global warming.
A study reported by National Geographic suggests that species extinction is happening 1,000 times faster with humans than it would be if humans didn’t exist.
According to the 2014 report “Human and Nature Dynamics,” which analzed the collapse or sustainability of societies:
The two key solutions are to reduce economic inequality so as to ensure fairer distribution of resources, and to dramatically reduce resource consumption by relying on less intensive renewable resources and reducing population growth.
And as many environmentalists would argue, corporate changes make a bigger impact than individual changes.
That doesn’t mean people shouldn’t eat less meat, invest in renewable energy sources, or use less plastic.
Those personal choices add up collectively. But not everyone has the means to install solar panels on their house or bike to work.
As environmental writer Martin Lukas wrote for The Guardian, “…individual choices will most count when the economic system can provide viable, environmental options for everyone — not just an affluent or intrepid few.”
How much responsibility should corporations be accountable for then? Well, according to the 2017 Carbon Majors Report, just 100 companies have been the source of more than 70 percent of the world’s greenhouse gas emissionssince 1988.
U.S. companies near the top of the list included ExxonMobil and Chevron. In other words, what big companies do matter a lot.
So while yes, you should say no to plastic straws, you should also use your voting power to elect people into office who prioritize climate change policies.
Or support retail companies who are making zero-waste targets. Because Earth will survive, but if we want life on earth as it currently exists to also thrive, it’s going to take a collective and global effort.
