Effects of Sand Mining on Palau’s Reefs Joshua Kloulubak SC-249: Environmental Concepts & Issues Instructor Sherry Ngirmeriil 21 July 2013 Abstract What are the negative effects sand mining has on Palau’s reefs? This research paper attempts to address the consequences of dredging erratically in the quest for modernization and what these threats can pose to the society should this continue in an unsustainable manner. Over the years‚ the ocean and reefs of Palau have been an important source

“The 10 Keys to Global Logistics Excellence” The constant population grow‚ globalization and economic growth makes logistics a primary focus for business‚ especially big ones. Thomas Friedman said: “supply chaining” is fundamental as barriers to trade and interdependence are reduced across the globe.” That pretty much means that every day proper logistics are more fundamental to business to succeed and prosper.

and central North Pacific. We estimate that an area of just one square kilometre‚ surrounding one of the sampling sites‚ could provide one-fifth of the current annual world consumption of these elements. Uptake of rare-earth elements and yttrium by mineral phases such as hydrothermal iron-oxyhydroxides and phillipsite seems to be responsible for their high concentration. We show that rare-earth elements and yttrium are readily recovered from the mud by simple acid leaching‚ and suggest that deep-sea

I think that we should and should not mine minerals.We should because it gives resources.We shouldn’t because we lack trained people and fuel. We can mine and find many resources.For example‚ minerals. The minerals we can find can be worth millions of dollars.We can fine minerals like silver‚gold‚copper‚lead‚tin‚and zinc.We can also use these to create thing not just for money. We can mine and find another resource.This resource is fuel.This is what we use to drive cars.The fuel could also
