After read ˇ§Deep Threats on the High Seasˇ¨, I have puzzle.  The problem 
seems relating to how large the carrying capacity of the ecological system 
is?  That is, ˇ§the ecological system can support how many people live in 
this world sufficiently.

Everyone attempts to get more and more and attempts to get better life. But, 
you know, no resource is infinite.  We can regulate fisheries to exploit the 
High Seas resources.  But, the people need to live.  If they can not satisfy 
on high seas resources, they might try to shift their demand to other 
resources.  Hence, the result is shifting the risk of some resources to 
others only.

So I think, we need to know how large the carrying capacity of the human 
population should be.  Of course, it is depending on what quality of the 
life will be.  Of course, it is also depending on how large the carrying 
capacity of the ecological system of the world is.   Of course, it is also 
depending on how large the carrying capacity of each available resource is. 
For high seas resources, do we know the carrying capacity and intrinsic 
growth rate of each species? ex., yellow fin tuna, albacore, blue fin tuna, 
shark, whale, bonito, skipjackˇK..ˇK?  If they are unknown, then how to know 
they are in good or bad conditions?  How to regulate the fishery?  Do we 
need to increase or decrease the resource?  As you know, the population 
dynamics of any resource is highly depending on the relative size between 
the current stock and the carrying capacity.



With my best regards
