Is china's production of seafood a ouitive or a negative for louisiana's seafood production

At best it doesn't matter. If there are enough fish to go around in both locations, then the two areas can coexist.

If however, the two jurisdictions are going  to be in competition with each other, then that's not good.

China's Output: 32.5 million tons = 32,500,000,000 pounds 32.5 billion pounds in 2004

Louisiana produced 1.2 billion pounds of sea food in 2005

Louisiana's output compared to China is quite small. I would guess most of it is for domestic use. It means that every man woman and child in the United States eats 3.64 pounds of fish a year. There won't be much left over for export. This does not take cat food into consideration. I cannot find exact statistics on sea creatures (like tune or salmon) that are put in cat food particularly (since they require meat) but it's going to cut down on what could be exported.

I don't think China has much of an effect on what happens in Louisiana.

they can increase to boost the enonomy.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
