A scientific study published in the journal Science
states that by the mid-point of the twenty first century there will very few marine species
left in the world's oceans. There are number of different causes all of which are linked to Human activity.
Stocks have collapsed in nearly one-third of sea fisheries, and the rate of decline is accelerating.
In 2003, 29% of open sea fisheries were in a state of collapse, defined as a decline to less than 10% of their original yield.
Experiments performed in small, relatively contained ecosystems show that reductions in diversity tend to bring reductions in the size and robustness
of local fish stocks. This implies that loss of biodiversity is driving the declines in fish stocks seen in the large-scale studies.

In some ways the report reminds me of the claims in the 1970's that the Earth was going to run out of oil by the year 2000. The estimated time line
was wrong but the warnings were and are valid. Given the lack of action or ineffective measures taken to combat climate change I cant see world
leaders taking any measures to prevent the loss of marine biodiversity.
First world countries and countries that don't owe the world bank an ocean of debt may be able to develop the likes of genetic food in order to make
short falls in there countries food supply once there are no longer sufficient food stocks to feed the population. The people that will suffer the
most from the loss of marine species will be the people who have fished the world's oceans for thousands of years in small native crafts. Those
people may not have another main source of food.
Its worth noting that there has been a reduction of biodiversity on land as well as at sea and that there isn't a single reason instead there are a
number of different causes which are contributing to the problem including pollution and bottom trawling .
