A short, 27-word Tweet from Neil deGrasse Tyson on Earth Day 2018 has perfectly illustrated why we're all in this together. 

The point is taken; this planet has survived five mass extinctions, and is in the middle of yet another. 

Of course, the sixth mass extinction that we are now in—without a clear indication of how severely it will affect life on the planet—is caused by humans; National Geographic estimates it's happening at a rate 1,000 times higher precisely because of Homo sapiens.

What can we do?

As individuals, we can recycle, eat less meat, that kind of thing. But as the Carbon Majors Report states, just 100 companies are responsible for 71% of all emissions. Think about that for a minute. 

In fact, more than half of all carbon emissions are from just 25 companies and state-owned entities. Near the top of the list? Exxon, Shell, BP, and Chevron.  

A possible revised slogan was offered by climate scientist Gavin Schmidt:

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

So yes, Neil deGrasse Tyson, the planet will go on. Humans and other life on Earth, however? Mmm... not so much.
