A nuclear war will wipe out a huge portion of Earth and with the short available resources the remaining survivors will just slowly starve themselves without any available medical treatment.

im adding you for that comment lol

Personally, I believe it will be something that collides with the Earth, other than that it could be a Nuclear War, although it won't be in our life time.

I don't believe any "god" will have to do with our worlds end. I feel as though us humans will end up killing each other in 1 big war over something stupid.

I dont believe this i remember listening to the radio the night before the world was supposed to end in 2012 or 13 i forget and this guy was giving lectures and stuff saying whats going to happen and stuff i woke up the next morning laughed got food and went back asleep i think its just an "old wives tale"

Nuclear war.
Our sun going nova.
The military releasing a virus on us. (chemical warfare)

None of us posting will be around to see the world end. Our world is still very young compared to other worlds that are much older than ours and still haven't ended.

Yea the world will end but its going to be a long time before that happens!

I think we will destroy ourselves before the world ends naturally.

Whether it be war, using up all our resources, polluting the earth, etc.

Everyone saying nuclear war... you do understand that no leaders with actual brain cells and respect for their own life want this? A nuclear war means we bomb each other, and no one wins because we have all bombed each other. So I don't think that will do it.

I doubt an illness will do it with how far we have come with cures and medical assistance.

Obviously it won't be a zombie apocalypse or anything, unfortunately.

I think that if something happens to do with an period of activity in how much the cancer cells in us populate, and become active that could wipe us out slowly. Although some believe we have cancer cures... because they don't want to release it due to them making money etc... remember there are countries who giveaway medical attention for free and are using resources treating people so I think thats a dumb idea.

Seriously I just don't thing anything is going to end us. I'm not religious one bit, so I don't believe in any wrath of god stuff. And the amount of time its gonna take for the sun to die out, who's to say we wont have invented spaceships or whatever and have intergalactic space travel etc... Or perhaps another life form comes to us, shows us a way to survive.

The truth is we don't know, and any theories are just that. Its a case of assumptions, and opinion.

Nuclear war will kill us all.

I don't quite agree with this. People live almost everywhere in this world. If a nuclear war happened and 99% of the population was wiped out we'd still have 70,000,000 people remaining. Easily enough to create a new world. I just seriously doubt nukes would kill off 100% of the population. I know they can but doubt they will. Nobody is nuking Canada lol

Yes but crops would fail due to radiation and almost all water will be contaminated so people will begin to starve
