Why should nuclear weapons be banned?

Hey guys who read up on this question.

Can I ask for some help with this question?

I am doing a debate in my high school class. And I am on the AFF (Affirmative side) Meaning I'm on the side who agrees to get rid of nuclear weapons.

I have some points here I will share. I was wondering if anyone else would have some other thoughts? Ideas? That would assist me in this debate.

Points:

1) Wasting the money on weapons research. (STAT-Nuclear countries spend about $37 Million every second on developing nuclear programs.) When we could use all that money now to help out our decreasing economy.

2) (STAT- There is enough nuclear weapons to demolish the earth 7times over.) Why use a weapon if it destroys part of the earth we now live on. Plus the nuclear fall out would devastate other countries not affected by the current conflict. (If there was ever a conflict)

3) Resources needed to make 1 nuclear weapon. Mining for Uranium, using up precious oil and natural gas to make weapons no really uses but for practice runs. Plus the resources needed to make 1 bomb is so radioactive, that if anyone person who tried to make one, would be endangering their own life. And if there was nothing to go wrong in the process the endangering of many other lives as well.

4) Considering that what I've gathered from numerous websites, most people around the world are in fact against the use of nuclear weapons. So why have them at all when it causes so many problems just to make one and then to have one in your possession
