Most do not seem to think much about the Asteroid that nearly changed civilisation as we know it .
Scientists said would take 10 years to deflect an Asteroid this size, how much hope do we have when only have 1 week warning for this ? Yes you should be scared . Apparently we can only detect 1% of the Asteroid materials coming to our system or earth itself, should we not be trying to improve this to save our planet/humanity ?
In space the impossible can happen, taking a risk it will not is simply sacrificing our species .
*Correction : We have spotted 10% of the Asteroids capable of causing "any sort of damage" and 90% of Asteroids capable of causing global disaster .
