FISHING FACTS:

·  Fish are important to the economy in every country

·  Fisheries (all of the fishing activities in the ocean) today provide about 16% of the world’s protein

·  Fishing in such mass quantities impact the environment

·  Overfishing is a marine conservation issue… BIG impact on the environment

·  Overfishing has led to a decrease in the amount of fish available. This is bad because the world’s human population is rising. Basically, we have more mouths to feed and less fish to feed them with. Not good.

DESALINATION FACTS

·  Freshwater, as we all know, is a limited resource.

·  Desalination is the process of taking the salt out of salt water so we can use it like freshwater.

·  Desalinated water can be used for drinking, irrigation, or in industry.

·  Table salt can be a byproduct of the desalination process (a byproduct is a useful substance made during a process)

·  The desalination process can be harmful to ocean life, especially to plankton, fish eggs and larva, and other small ocean organisms that may get caught in the intake valves.

MINING FACTS:

·  Diamonds are found in greater quantity in the oceans than on land!

·  Metal compounds, gravels, and sands are popular

·  BIG impact on the environment… VERY BAD for ecosystems

·  Dredging (pulling a net across the bottom of the ocean catching everything in its path) destructs habitats and kills unnecessarily. Also, a cloud of sediment blocks sunlight and interferes with photosynthesis

OIL RIG FACTS:

·  AKA “Black Gold” – One of the ocean’s greatest resources

·  We make gasoline for cars, diesel fuel for our trucks and ships, and jet fuel for our airplanes.

·  Oil is also used to generate electricity, heat our buildings, lubricate our machines, and make plastics, detergents, types of rubber, and chemicals.

·  Oil has made a HUGE difference in our lives – nearly 1/3 of the world’s oil comes from offshore fields in our oceans.

·  Oil accounts for almost half of the world’s sea trade

·  Oil comes from the skeletal remains of phytoplankton and zooplankton that settled to the sea floor, mixed with mud and silt, and over millions of years, formed organic-rich sedimentary layers. These layers are buried deep under layer upon layer of sediment. As depth increased, pressure and temperature also increased. Under these conditions, over long periods of time, the skeletal remains changed into hydrocarbons – compounds of hydrogen and carbon. This is oil.

SHIPPING FACTS:

·  Shipping (moving cargo with ships across oceans) is a major use of our oceans.

·  Types of ships: Naval (trade and navy), Commercial (trade), Recreational (cruises)

·  Low impact on the environment J
