100,000 Years From Today

How do you get to doomsday?

Subtract whole multiples of 7 from the result of calculation 5. This will result in a number between 0 and 6, which corresponds to the doomsday of the year. Example: 16 - 14 = 2, so the result is 2. This means that the doomsday in 1978 was a Tuesday.

How can we stop human extinction?

Eat less meat, to reduce agriculture's clear-cutting of rainforests. Never buy anything made from ivory. Adopt a species, or become a "citizen scientist" for a conservation group. Vote for leaders who recognize the importance of conservation and carbon-neutral energy policies.

Will humans go extinct if bees do?

In terms of agriculture, the loss of bees would dramatically alter human food systems but would not likely lead to famine. The majority of human calories still come from cereal grains, which are wind-pollinated and are therefore unaffected by bee populations.

Will dogs become extinct?

While it's less likely than in the past, there is still a chance more dog breeds will go extinct. Unfortunately, the most likely reason a dog breed will go extinct now is due to a lack of human interest. There are plenty of rare dog breeds still out there.
