The world is very far from being an ideal place, with there being a tremendous battle with sustaining a massive and growing world population. The reality is that we manage to live on a knife edge and if this population is to be catered for in any way at all, decisions will be made that will turn out to be sometime good, and sometimes horrifically bad. Sure, Fukushima is a human catastrophe, but it wasn't intentional. We just have to learn and move on - because that's all we can do, unless you want to just shoot yourself in the head right now because of it, if you think it helps.
The bottom line is that the human race is bloody clever and the achievements that we have made, especially in the past 50 years are extraordinary, and the next 50 years will probably be even more so considering the exponential rate at which technology and achievements are advancing.
We live in incredible times, with amazing successes in beating some horrible diseases, and generally making quality of life and life expectancy better than ever.
I think sometimes it may be best to think, on the whole, how lucky we are, rather than always focusing on the negative. Sure there will be some bad sh1t, but life isn't risk free. It never was and if you sit and waste it pondering on everything that's bad in the world, then you may as well end it now.
This is what we have. Accept it, appreciate it, and get on with it.
I've had a friend staying for a few days that is negative to the degree that I feel completely mentally drained. Negativity is self-fulfilling and it sucks the life out of you.
F&ck that. Life on the whole is good if you allow it.
