Do you have faith in the future of our existence?

Yes, I believe we are smart enough to know when to join hands without pride and prejudice and fight the adversity strongly...... although that is no guarantee for continued survival, it's certainly the best available assurance.

I think that the big event and near undoing of mankind is going to be a major nuclear war at some point in the future - it only takes the wrong person getting into a position of power, something that is bound to happen at some point, as it has in the past(history does not bode well for us-especially the USA and democracy). I doubt that it will trash the entire globe - there will remain pockets of liveable and arable land where survivors will be able start anew - but I do believe there will be a massive die-off of the species.

Geologically, there is always the possibility of another ice age linked to phases of the suns activities or massive volcano eruptions or other events that shield the earth from the warming of the sun.

I agree with other posters that population growth, if unchecked, will eventually lead to massive conflicts for food and water(which is already a problem in some parts of the world). It would not surprise me at all if some countries(China?) were to become desperate enough to invade and take over neighboring countries for food and water, lack of which will certainly lead to desperate actions.

One poster suggests that we always find ways around problems and that everything will eventually turn out OK. I think this would apply in a world driven by logic and reason as opposed to pure whim and desire - but I do not see the mass of the human population as being so disposed. "Science" will not, in my view, find solutions for these problems, many of which involve limited and unalterable natural resources.

My ramblings on a question that concerns me since I care for my children and grandchildren and future generations.

Of course not, second law of thermodynamics - everything tends towards entropy. We cannot exist indefinitely.

Edit: In that case, ye I think we will manage a bit longer than 30 years - I'm putting my money on the deciding factor being whether or not we can achieve cold-fusion before our natural resources run out.

No I'm pretty sure the human race is done for. I give us less than 100 years. Were running out of water food climate change over population were going to have to figure out how to deal with these problems and quickly or were done.

Sure. We have survived far worse. About the only thing that will make man extinct is a world-wide convulsion of some sort. (meteor, comet, expanding sun, etc)

Fact is in front and faith is in rear from your eye.

No.i don't see any future for mankind.it will go extinct at some point.

i am always the optimist. it will be only as good as we make it and we can do great things when we put our minds to it,

i believe future is depend on a way, u have to chosen in present......
