Why shouldnt they hunt whales in a sustainable way ? I've asked this question before but no-one can give me a good reason.

'tis an emotional rather than logical argument.

The evidence that there is suggests that most species of whale are still endangered and extremely vulnerable, and so "sustainable" hunting is still out of the question. Minke whales may be the exception, but there is still insufficient data on which species of minke whale are recovered enough to support "sustainable" harvesting.

Killing off 900 or so minke whales a year as "research" is just bollocks.

Thats just the factual side of it. I also oppose whaling on the "emotional" side.

They don't , they can't , it is not possible .

Great argument, Mid, truly sublime, splendiferous and incontrovertible argument.

Why doesn't anyone go on about the Norwegian whale hunt? Or the Eskimos? Why is only Japan the bad guy?

Dunno exactly, but they couch it in terms of traditional hunting - not hide behind fallacious 'scientific' research.

Plus the fact that the Norwegians don't hunt inside the Southern ocean whale sanctuary - which the japanese do......

Dead whale is a deal whale isn't it? And the population in the south is the biggest.

In simple terms, more whales mean more algae growth which apparently starts it's growth cycle best on the skin of whales for some strange reason. just as land based plants remove CO2 from the air, pushing out oxygen, so does Algae. So, more Algae means less CO2 which in the long run means less rain and strange out of season storms for all of us.

I think you had better do a bit of homework Prof ,Plants produce CO2 at night thats why they almost always take all the flowers out of hospital wards at night ,due to photosynthesis plants produce Oxygen only in the day time .

Actually, not 100% correct there, but it's a common mistake. Plants respire day and night. (Which produces CO2)

that would be high school science, whatever link you've found on yahoo answers it obviously wrong. I'm not here to argue with you about it, just saying.

Answers

High school science is a bit advanced for me (according to many on the board!), but:

Photosynthesis is basically the production of sugars (food) from water and carbon dioxide -with the subsequent release of oxygen. This requires light (absolutely) and so happens only in the day. Large amounts of oxygen are produced.

Respiration is the process by which cells break down the produced sugars to provide energy - which results in the production of CO2. Energy is required all the time by the cell - and so this process goes on day and night.

In the day, the photosynthetic process predominates - the little bit of CO2 being produced by respiration can actually be used in the photosynthetic pathway, resulting in an overall net production of oxygen.

In the night, with no photosynthesis, respiration predominates, resulting in a net production of CO2 (which is not used in the photosynthetic pathway which is off).


So, photosynthesis - light requiring day only
respiration - day and night

A meticulous reply , So Plants produce oxygen by day and Co2 at night then , cheers

Hmmm. Plants produce CO2 day and night, but 02 only in the day is a better way of saying it.

yes but that doesn't suit the argument , now does it ?

Indeed. Can see why SW passed on it.......

And obviously too involved for you to follow, because you've completely misunderstood what he said.

But nicely explained, nonetheless.

I think I'll settle for this linkWhy do plants take in oxygen and release CO2 at night

wiki.answers

you do realise that link says what we have been saying all along ?

That plants respire day and night and thus produce CO2 all the time.

And that they only produce O2 during the day, due to the light dependant reactions needing sunlight ?

All of which is a pointless diversion. They are net consumers of carbon yes?
Anyway, I'm not sure of this whole argument, krill eat algae, whales eat krill. Though some whales eat plankton which are also sequestering carbon.
So is the argument for whales = less krill and therefore a higher algae population?
I don't think that would be the case, is there ever a shortage of algae due to overfeeding? I would have thought it would always bred to occupy available space in the habitat.

What does the heading on the link say?

Faark me, are you being deliberately thick ?

Your link talks about Night, only.

You keep stating that plants do not respire during the day, when they clearly do.

But carry on.

No are YOU so Thick, all I am correctly contending is that plants produce CO2 AT NIGHT ,show me please were I ever wrote that"plants do not perspire during the day" , of course they do otherwise they could not live FFS stop being so pedantic and just STFU
