This is no different to the fight over legal "canned" hunting today Adam Ruins Everything did an episode on it https://www.youtube.com/watch?v=YUA8i5S0YMU Basically canned hunting upsets the do-gooders but in reality is good for the species and banning it increases poaching which wipes the species out, so by trying to save the species, people are actually ...

They charge an arm and a leg for every trophy. Then they repay any damage the dragon did during its life span, and split up the rest among the population. This has to be more money than the people can get by poaching, or by accepting bribes from illegal hunters. (In particular, the egg situation makes it appear that people were attacking the nests as ...

I went put it as comentary only: Seems the Moon will looks like Earth in Adventure Time. Also, if possible, hit hard in Brasilia, please. The accident can be some cargo mined in outer solar system no landed properly in the Moon. If there exist a complex industry, its plausible they will need some different minerals that are most easily to find in Ganymede,...

The dino-killing asteroid has a size estimate between 11km and 81km. Checkout this video with some asteroids placed upon the city of New York, to give you an idea of size. The Dino killing one would be somewhere between Eros and Shaposhnikov. In other words - in the lower estimate big enough to cover the city in shadow, in the larger one bigger than the city....

You cannot do this with "an explosion" for the reasons illustrated by @HalfThawed. You would need the equivalent of a fizzle cannon shot - dig a very deep pit, have a very large "boulder" (a mountain actually) inside, have some reaction create a sufficient overpressure in the pit that the mountain is launched towards Earth but not so quick and violent that ...

Actually, my comment on your question may make a good answer. In The Moon is a Harsh Mistress Heinlein has the moon residents configuring a rail gun materials transporter, used to launch moon minerals into orbit, as a weapon against the earth. How about a fully automated alien mining venture, unattended, that mines minerals on the moon and automatically ...

The Earth and the Moon are pretty far apart. In order for something to go from the Moon to Earth, it needs to escape from the Moon's gravity and then have an orbit which brings it into Earth's field of influence and then crash into Earth. Normally, the way we send ships to the Moon involves said ships boosting in orbit around Earth in order to achieve this ...

A single large meteorite would be enough to end civilisation by means of a 'nuclear winter' dust cloud. Crop failures, famine, societal collapse, cancellation of important Netflix series etc. As an order-of-magnitude estimate, something a mile across would be a global catastrophe. Anything much bigger and you could cause a major extinction event and not ...

For a week, beer is all you need. It is actually highly nutritious. A beer and a vitamin pill and you are good to go. In England, no need for heat. It has very temperate weather. Do you seriously need Internet? Does your protagonist have a cell phone? The cellar would certainly have lighting, and therefore electricity, but this would take some hand waving in ...
