Potential Future Disaster From Nanotechnology
There is danger from future widespread use of nanotechnology. It is seen as the new savior to save the world from food shortages and so on. But like bio-fuel production it could do more harm than good. CSIRO is calling for more study of nanotechnology. This is despite the fact that no country has yet examined safety issues involved with it.
Nanotechnology creates "micro-fine" products that have no safe disposal system. If they get into the environment there is not telling what damage they could do.
Risks are seemingly endless: use by terrorists; environmental damage; self-reproduction (goo everywhere); even the future of Mankind on this planet could be under threat.
Once a material has been modified or a new nano-product created it becomes a permanent structure. It must be chemically altered to make it safe. A nano-substance is not inert. It will act on the environment if it can. At the moment there are no restrictions. Developers can do what they wish. Let's hope regulations are put in train before a disaster occurs.

If Fishing Is Not Reduced There Will Be Little to Sell
Consumers will have to learn to do without. If we want our children to enjoy seafood we will have to eat less of it now. That means paying a higher price.
A guide has been put out by the Australian Conservation Society to make people aware of what species are in danger. This Christmas consumers have bought lobster, bugs and mackerel. It is debatable as to whether all of these are actually threatened.
Not everyone is in favor of informing the general public about the need for change in the seafood industry. The Queensland Seafood Industry Association, in particular retailers the body represents, are angry because they fear a fall in income. They are saying the industry is already struggling. Yes, it is struggling because seafood is becoming more difficult to supply.
It is really a case of "someone has to pay and it won't be us". They say fishing boats have been bought and licensing fees have been paid. The reality is, however, that if fishing is not cut back there will not be much to sell.
