I think in China parents are limited to 2 children. If our country did that it might help with the over population of this country. It also seems our group is more concerned about global warming than the religious fools. They believe in the fairy tale that Jesus will made an 2nd appearance on Earth and that will making our planet uninhabitable one day is ok . That's another reason I left that backwards way of looking at things.

I feel like atheists and agnostics are less shackled and perhaps more thoughtful when it comes to science and how science and technology can make the world a better, more healthful place. I think we are also less shackled when it comes to dealing with human abnormal psychology.

I do not hold the view that "only atheists" can provide some answers. Not all theists are equally judgment-impaired / limited in all contexts. There are things I can solve with most of my fellow humans, and I have a unique contribution to that based on my individual perspective and helped along by critical thinking -- of which atheism is but one side-effect.

You are however correct that if you think your imaginary friend will prevent or solve certain problems you aren't as likely to act upon them, or even to recognize them. Fortunately the percentage of Christians who literally think that is relatively small, probably sub-20% on a worldwide basis. In turn, Christians on a worldwide basis, by the most encompassing possible definition, represent about a third of all persons. So the literalist / fundamentalist mindset is not much more than 5% of humanity. I therefore conclude that I can find common cause with at least 95% of humans, most of whom have no idea I'm an atheist to begin with.

super volcanoes have no solution there are over 20 and if 1 goes off which they do every 100000 yrs or so it would be fairly bad news but probably not a total extinction event though life would get real hard real fast. Global warming is causing so many different problems that we are probably almost past the point of reductions in fossil fuel usage etc etc making any difference, most scientists already think we are in the 6th mass extinction so anything we now do is likely to little to late.
Asteroids are the one that almost everyone agrees its not if its when one hits, as we would need several years to put together a plan and see it through i don't like our odds and if its so big say 100kms across deflecting it may be impossible to start with also any quick look at NEO websites does not fill one with joy.
Our own mortality is currently 80-100 give or take you mentioned overpopulation so if some miracle procedure does appear in the near future most likely through crispr would it not just send us down an ever quicker route to starvation lack of water lack of habitable land etc

• Global warming - We were making inroads and then the right stepped in to quash everything. So... enjoy that fracking fluid in your drinking water please!
• Overpopulation - Unfortunately the stupid people are reproducing faster than the intelligent ones. Watch the first 10 minutes of the movie Idiocracy to see what I mean. Watch the rest of the movie to see how the world ends.
• Species extinction - Mother nature has a way of dealing with this. This is where your next two points come in. The world WILL have a bottleneck soon enough. A time when something so violent happens it wipes out ALMOST all life. The Earth will cleanse itself and repair the damage we have done. Yellowstone is not a bottleneck... But it will make life rough for a lot of people. Gimme an asteroid about a mile across... That will do it!
• You left out coronal mass ejection. This is likely soon. It will fry the power grid and throw us back into the 1880s for quite a while. This is your zombie apocalypse..

• Hey... Have a GREAT Sunday!

what, atheists, as diverse as we are, should be superior in character to theists? some of us are petty and some of us are not. if you have some discussions to start (it's really hard to start a discussion with "we should be discussing this" but, you know, present the problem, or present the solution, or something) go for it. but you know, enjoying discussions about a variety of topics, some of which are vital world issues and some of which are just fun, does not make us petty. it's just human.

I think that if you looked into it a bit further you would find that a lot of us are already involved in these issues. Many of us already belong to political parties and/or pressure groups which are trying to change the world and in most cases improve it for the majority. In addition, I think you are conflating a number of different types of issues, some of which we can do something about, others we can't. I don't think anything I do will affect the timing of the eruption of a supervolcano or an asteroid collision, but I am doing my best to bring in a government in my country that will pay more attention to global warming and species extinction. If you look at the posts on some of the groups available, you will find plenty of people keen to share their ideas on such things.
