Knowing, If such things happened to our earth, will we all perish?

Well, the above question is worth pondering about . Its just like, the current situation is already that bad, what if something worse happened? And people are just not helping, but contributing more to global warming. I know what I'm saying now is totally senseless. And not to mention I am one of the people. Its as if, ok example, our geography teacher always tells us to stop global warming, save our earth and blahblahblah. We treat it as some nonsensical joke she's telling, and we don't do anything about it. But, I was really enlightened today, like really. So I started thinking. There are so many things that could happen to us. We may, or may not be able to stop it. It just depends. Plane crashes, subway accidents, droughts, acid rains, any other natural disasters. Or even heatwaves from the sun. Maybe its rarely it happens in Singapore, and only like in other countries, mostly America. But there are always possibilities, and we can't afford to risk it. And its really weird for someone like me to blog abut something like that. Cos I know I do alot of things, that contributes to global warming. But I just want to let others know. Alright, I shoud really stop scaring myself.
Ok yeah, woke up at 9 today. My dad came back from Vietnam so we went out. To eat lunch, that was supposedly breakfast, I'd rather not talk about it. So we went to anchor point. Ate and then walked around. Then me and my sis went to some artist for him to draw a portrait of us. I'm too lazy to upload the picture now, maybe later. But I can describe, I look NOOB(: Right, whatever. I really lazyyyyyyyyyy to type the rest of the day out. super tired. Anyways, went to watch the mivie "Knowing" . Damn cool.(: Byeee!

Just heard from my sis about some thing called "dopple ganger". Its said that ppl believe that these things look exactly the same as you, but in a sort of different form, I dunno what. And they say that if you happen to see them, or your friend's, you will die soon after. Its a sort of legend or something. And it was also rumoured that Queen Elizabeth died because she saw her own "dopple ganger" . And another poet saw his own, and died shortly after. Haha, not sure whether its true or not, but it sure sounds scary. Heh(:
