This is the the lie that I'm really tired of people repeating. Nuclear waste isn't THAT dangerous and doesn't have to be kept perfectly isolated for THAT long.
"In the future, 600 generations from now, when the poisons we lay down now are bubbling up,"
You should really be more worried about the 36 billion tons of CO2 we are spewing into the atmosphere every year instead of a TINY amount of nuclear waste many thousands of years in the future.
You are like someone with a malignant tumor worrying about the risks of radiation therapy.
