Most probably, the situation of the earth being hit by a comet of the same size that caused the end of the dinosaurs. Scientists think that your best option would be to live around the spot where it hits, because then the end would at least come immediately without you even knowing what hit you.
For those people and places surviving the initial earthquakes, tsunamis and firestorms and the resulting near-total collapse of trade and shipping, industry and infrastructure in most countries the result would be living under a dust cloud that would turn the earth surface almost pitch dark, ice cold (after the last remaining local oil reserves for heating and electricity had been spent) and unable to produce the food that we need to survive for the next thousand years or so. Loss of electricity would of course also mean loss of all those computer-driven or supported services like public services, finance and health care. So that means a starvation / freezing to death-scenario for almost all of the initial survivors. In a situation like that, even the most wildly optimistic estimates put the long-term survival percentage at less than 10% of today's human population.

What is the factor most likely to result in a decrease in the size of a specific population is?
An increase in predation pressure or a decrease in food availability are factors most likely to result in a decrease in the size of a specific population. These factors can lead to increased mortality rates and reduced reproductive success, ultimately causing the population to decline in numbers.
A situation in which allele frequencies change as a result of the migration of a small subgroup of a population is know as the?
founder effect
What factor will most likely result in an increase in the size of an animal population?
An increase in the availability of food, a decrease in predation pressure, or an improvement in reproductive success are factors that can lead to an increase in the size of an animal population.
Why city become a town?
A city may become a town due to changes in population size, economic activity, or development patterns. It could also be a result of a decrease in city services or government reclassification.
What types of reproduction is most likely to result in a rapid growth in population?
Asexual reproduction is most likely to result in a rapid growth in population, as it does not require mating and can produce many offspring quickly. This can lead to exponential population growth under favorable conditions.
Which situation most like would result in the greatest change in gene frequency in population?
competition between the organisms

Decrease in fox population is a result in?
There are many contributing factors that could be the cause for a decrease in fox population. Over population, not enough food, disease, or over hunting or poaching any of these could be the reason for a decrease in the population.
What change to this food chain would most likely result from a decrease in the mouse population?
decrease the number of hawks

The greatest reduction of human population in recorded history was the result of?
The Black Death.
A situation in which allele frequencies change as a result of the migration of a small subgroup of a population is know as the?
