Furthermore drought in Russia, Europe, and Australia means they aren't having bumper crops to offset that loss.
I can't speak for Russia or Europe, but Australia is definitely not in a drought and hasn't been for at least the last 2 years. In fact at the moment we are in the middle of a La Nina event, with more flooding than anything else. Most of our dams are either at 100% capacity, or close to that as well - they'd in fact all be at 100% if it wasn't for "environmental flows".
Wow, exaggerate much?
Let me answer some of the angry points you made, ok?
And those going to Mars will also have a breathable atmosphere. It is just that it will be a limited confinement.
Indeed, they will have a very limited breathable atmosphere that they have entirely imported with them from Earth and will be reliant for the rest of their lives to ensure that the machines which maintain said breathable atmosphere do not break down.
Look, just because you are afraid of the unknown, does not mean that others are. Many would willing give their life to help build an establishment for their country or just for science. When my children are adults and able to take care fo themselves, I would volunteer (though my wife is likely to nix that). Why? BECAUSE IT IS A BETTER FUTURE FOR ALL. We NEED to take RISKS. Without those, you do not have the opportunity to make huge discoveries.
There's hardly anything unknown to fear here. The risks are entirely known, although granted, it is possible that there may be some unexpected issues that crop up when we finally do get to mars that the boffins on Earth hadn't foreseen. And yes, if the issue was to start a colony on Mars without a return trip to Earth, then that is fantastic, but more likely, this will be a one way mission for a bunch of astronaughts to do science and not actually establish a colony. Colonisation of Mars is highly unlikely to take place any time in the next 25-50 years. Further, our need to take risk must be mitigated by the potential gains. What exactly is it that we would gain by sending Astronaughts on a one-way almost certain suicide mission at great expense to Mars, which cheaper unmanned missions could not accomplish?
Personally, I am tired of those that want to conqueror others on this planet for their resources (read murder), but then get upset about out taking risks that MIGHT kill a person. The west use to be heroic and be willing to get it done. Now, we act like our individual life is all that. Give me a break.
WTF? Now you're just ranting off at a tangent. How about, personally I am just tired of people responding to a post in a knee-jerk manner and making all sorts of assumptions based on zero factual evidence.
This is now. Later is later.
