If anyone can add or cleanup this article, please do. Ecology's really not my thing; I only wrote this to stop people from creating nonsense articles here. — Knowledge Seeker দ 06:24, 11 Apr 2005 (UTC)

Moot. Continue on Talk:Planetary boundaries? 99.119.128.35 (talk) 21:42, 30 March 2011 (UTC) Wrong. And we have not resolved the question of whether any tangential links to planetary boundaries are appropriate. — Arthur Rubin (talk) 10:17, 31 March 2011 (UTC) Arthur, please help me understand what you are attempting to say, what tangential links? Did you say you wanted supporting links (a separate source relating) in Talk:Ocean acidification? Wouldn't the Talk be simpler on Talk:Planetary boundaries if you make slightly different comments on the related boundaries' articles? 108.73.113.97 (talk) 00:50, 1 April 2011 (UTC) As far as I'm concerned, and unless you can provide a consensus otherwise, any link from a "planetary boundary" to planetary boundaries is tangential. Much of this discussion could be centralized in Talk:Planetary boundaries, but, even if there should be a link from the boundary to planetary boundaries, with some rare exceptions, you've selected a clearly wrong article to link planetary boundaries from. — Arthur Rubin (talk) 05:30, 1 April 2011 (UTC) The only one I see not in consensus is you Rubin. That is the one and only thing that is clear, I see. 99.190.87.1 (talk) 18:32, 1 April 2011 (UTC) The only one I see in agreement with you is you. — Arthur Rubin (talk) 06:15, 2 April 2011 (UTC) More: Stephen R.

That abstract does not say that. — Arthur Rubin (talk) 07:43, 15 April 2011 (UTC) Phosphorus (P) is a critical factor for food production, yet surface freshwaters and some coastal waters are highly sensitive to eutrophication by excess P. A planetary boundary, or upper tolerable limit, for P discharge to the oceans is thought to be ten times the pre-industrial rate, or more than three times the current rate. However this boundary does not take account of freshwater eutrophication. We analyzed the global P cycle to estimate planetary boundaries for freshwater eutrophication. Planetary boundaries were computed for the input of P to freshwaters, the input of P to terrestrial soil, and the mass of P in soil. Each boundary was computed for two water quality targets, 24 mg P m − 3, a typical target for lakes and reservoirs, and 160 mg m − 3, the approximate pre-industrial P concentration in the world's rivers. Planetary boundaries were also computed using three published estimates of current P flow to the sea. Current conditions exceed all planetary boundaries for P. Substantial differences between current conditions and planetary boundaries demonstrate the contrast between large amounts of P needed for food production and the high sensitivity of freshwaters to pollution by P runoff. At the same time, some regions of the world are P-deficient, and there are some indications that a global P shortage is possible in coming decades. More efficient recycling and retention of P within agricultural ecosystems could maintain or increase food production while reducing P pollution and improving water quality. Spatial heterogeneity in the global P cycle suggests that recycling of P in regions of excess and transfer of P to regions of deficiency could mitigate eutrophication, increase agricultural yield, and delay or avoid global P shortage. Bolding is mine. Reconsideration of the planetary boundary for phosphorus is the title, if you are still confused (and confusing). 99.181.133.155 (talk) 03:48, 16 April 2011 (UTC)

Ionic phosphorus?

"Phosphorus is an essential nutrient for plants and animals in the form of ions." Are not the phosphate units incorporated into organic molecules always or typically phosphates (PO4)?--Wetman (talk) 18:18, 3 December 2011 (UTC)

PO₄^3- is the phosphate ion. I'd assume that is the ionic form referred to in the sentence. Vsmith (talk) 02:58, 4 December 2011 (UTC)

Copyvio removed

I've removed a bit of cut-n-paste copyvio from the Human interference section which was added back in 05 2010 by an ip. Vsmith (talk) 23:44, 18 February 2013 (UTC)

Planned Changes to the article

In the eutrophication tab, there is a section dedicated to wetlands/freshwater systems. I would like to add a section about how eutrophication also impacts the oceans/salt waters. Would this be a good idea? MitchKrings (talk) 16:16, 26 March 2024 (UTC)

I also am going to edit some of the human impact section to give it more quantifiable numbers and to help it flow better. I also altered the lead a little bit to reflect the information that I'm adding as well as to tweak some of the wording to make it run together more smoothly.
