Answer 2

A species becomes extinct when it can no longer adapt to new conditions. When there is a big change in the environment the first species to go are the ones which are very specialized. The less specialized species (generalists) have more options and can often find a way to get through. Then some of their descendants evolve to form the next generation of specialists. This can be seen in some species that have lasted since the earliest eras of life. Roaches, dragonflies, crocs are good examples. Generalists eat a wide variety of foods, are mobile, and can adopt different strategies to meet different conditions. Rats are one of the best at this.

Humans got their start by being generalists. We aren't as strong or as fast as some predators. We don't have sharp teeth or claws. But we do eat a wide variety of foods, we can get around, and our brains give us the ability to plan ahead and think of solutions to new problems. On the other hand our very success may be our destruction. Apart from weapons of mass destruction we have through our civilization become a race of specialists. Most city dwellers would starve without stores and the food industry. Most people don't have a clue how to survive if civilization collapsed. A few smart one might figure it out and there are survivalists and "primitive" people who might do just fine.

I think our biggest threat is some sort of disease. Our medical advances allow some people to survive to adulthood that wouldn't make it in a more primitive society. So humans are not as subject to the "survival of the fittest" rule as are wild animals.This rule says that weak members of a species don't often get to breed so only the genes of the strongest and healthiest get passed on to the next generation. Our compassionate nature and medical technology are allowing the genes of many people to continue that otherwise wouldn't. I am concerned that the average immune system of the world's population is getting weaker. At the same time germs are evolving to become resistant to our best antibiotics. Someday a super bug will come along that overpowers all our drugs and immune systems. While it might not kill everybody directly, the damage to our infrastructure would be so great that the survivors of the disease might not be able to cope.

Answer 3

Our own stupidity , we will create a disease that will escape and wipe out millions of people , or we will create something even more powerful than a nuke . In 2029 , there will be an asteroid that will pass between the Earth and moon , if this asteroid changes course by just few meters , it could be a planet killer .

Answer 4

Nuclear war coupled by savage methods of dealing with the survivors by the strong and greedy.
