Which Resource Will Earth Run Out First?

Having two young kids, like many parents, I am starting to look at life differently, my goals and ambitions have changed over the last few years. Today I am now seriously thinking where in the world would the best place be to live and bring up my children. My question to the people in the know is where on Earth would be the best place to live in 20yrs time.

As a planet we are running out of resources, so what will be the first resources to go? I heard someone say that if the whole world moved onto Nuclear power, there would only be about 10yrs worth of resource left to produce the materials for nuclear power stations. Solar power is also not a long term option as the materials for making the cells would also run out very quickly. So which country has the most natural resources?

Would love to hear peoples thoughts. Please leave a comment.
