With a pandemic the problem generally arrives in your country from another one - there's a major "blame game". Same with climate change.

Meteor is different, the problem comes from outside.

In a pandemic, politicians have no incentive to give up on their autonomy as their electorate doesn't demand a global solution.

If a meteor is about to wipe out everything, global interests are actually aligned. That's not the case in a pandemic.

Because the meteor would affect rich people.

Wasn't it?

The pandemic doesn't have a clear fix. Lockdown, vaccinations, etc. only slowed it down. Even China's extreme measures to achieve zero COVID was not able to make it happen.

Kung Flu was an internal threat since it was created by the chinese with american money.
