An international asbestos ban is a good idea. These days there are so many different alternatives to using asbestos that are a whole lot better for people and the environment that a ban on asbestos would not affect any one negatively. It would just save lives from dying premature deaths.
Asbestos is a known toxin upon removal, therefore isn't good for anyone, anywhere. While precautions can be taken to reduce occurrences of illness due to asbestos, the best solution would be to remove it all together. Where asbestos exists, it presents a potential danger to the community, and therefore should be banned internationally, to protect all people from this potentially hazardous material.
