What are the motifs in Skeleton Coast by Clive Cussler?

Technology is a recurring idea. The technology of this day and age has both its advantages and disadvantages. The advantages are plain to see. We create cars that run cleaner and use less fuel; we find ways to reduce our carbon footprint on the planet by using solar and wind power where we can; and we try to minimize our impact on the dwindling resources while doing as much as we can for the species on our planet who are nearing extinction. While a great many people on the planet are still oblivious to the precarious position we are in, and go about their daily lives as though nothing will ever change - there are almost as many who are working towards a solution.
