With the human activity associated with industrialization, however, came the burning of fossil fuels for manufacturing and transportation, putting more carbon dioxide into the air and creating an increased pressure of this gas on some regions of the earth's surface — including coastal areas.

Since fossils in general, and dinosaur fossils in particular, are rare and very different from modern animals, it's lucky that humans came wired to spot the unusual, and collect the oddities that resembled ancient life forms long before there was a subject called palaeontology.

What makes the climate predicament even tougher is the uneven nature of human development, and the reality that nearly all of the growth in emissions of greenhouse gases is coming from a near - inevitable burst of fossil fuel combustion in fast - growing developing countries.

Most of these perturbations, tied either directly or indirectly to human fossil fuel combustion, fertilizer use, and industrial activity, are projected to grow in coming decades, resulting in increasing negative impacts on ocean biota and marine resources.
