'When I first became involved in advocating for eastern #tarakihi in 2019, #Fisheries New Zealand’s own #science estimated the eastern stock had fallen to around 16% of its unfished #biomass—well below the 20% soft limit and nowhere near the #Harvest Strategy Standard target of 40%.

'Six years later, we’re paying substantially more at the checkout, yet the eastern stock remains well under a rebuilding-plan target.
'Recent projections suggest it is still hovering around the lower management thresholds, with recovery far from assured under current catch settings.
'That should concern every New Zealander.
We’ve somehow normalised the idea that a fish can become increasingly expensive while remaining chronically depleted. Consumers are paying more, commercial operators continue #fishing, and we’re repeatedly told the #fishery is being managed “#sustainably”.

'If this is what #sustainability looks like, perhaps we need to rethink what the word means.

'A truly #sustainable fishery shouldn’t require decades of rebuilding while the stock remains well below the level our own management system says it should achieve. It shouldn’t leave us debating whether 10–20% of the original spawning biomass is acceptable, and it most certainly shouldn’t have us celebrating modest improvements while remaining nowhere near the target.'
.....
'Perhaps the real question isn’t why the price has risen, it’s whether we’ve convinced ourselves that #depletion has become an acceptable definition of sustainability.

From #Arctic heat to #megafires, #WMO report shows climate change completely reshaping #Europe

By Andrei Ionescu, 6/2/2026

"In the far north, climate change is not some distant warning anymore. It is already reshaping the landscape.

"Across Alaska and Canada, Arctic and boreal regions are warming up to four times faster than the global average.

"That puts a huge amount of pressure on #ecosystems that have long helped slow climate change by pulling carbon dioxide out of the atmosphere and storing it in #trees, #shrubs, and #soil.

When forests stop helping

"The trouble is, those ecosystems do not always stay helpful under stress.

"As wildfires grow more intense, drought becomes more common, and other disturbances spread, parts of the north may start giving #carbon back to the atmosphere instead of locking it away.

"Once that happens, the whole climate system becomes harder to stabilize.

"That is why scientists care so much about #biomass, the total amount of living plant material across these landscapes."

Atlantic Meridional Overturning Circulation (#AMOC) is a massive #ocean_current in the #AtlanticOcean, driven by #temperature and #salinity changes (#thermohaline circulation). It influences global #weather significantly:

- Warms up #Arctic, East #Canada, #BritishIsles & #Nordic region
- Cools down #GulfofMexico, #Amazon & #Africa
- Drives #rains in all these regions
- Supports a huge #plankton #biomass, that:
- Supports higher #marine_life
- Acts as #CO2 #carbon_sink.

#Sweden - Removal of #PFAS from water by #AquaticPlants

Maria Greger, Tommy Landberg
February, 2024

Highlights

• High total biomass is important plant trait for high PFAS accumulation from water.
• Higher PFAS accumulation in shoot than roots with time.
• Degradation of PFAS with root peroxidases and laccases.

Abstract:

"We have found that aquatic plants can reduce the content of perfluorinated alkyl substances (PFAS) within a short period of time. The aim of this study was to determine the variation in the uptake of PFAS from contaminated water by various #wetland plant species, investigate the effect of #biomass on PFAS removal, and determine whether laccases and peroxidases are involved in the removal and degradation of PFAS. Seventeen emergent and one submerged wetland plant species were screened for PFAS uptake from highly contaminated lake water. The screening showed that #EriophorumAngustifolium, #CarexRostrata, and #ElodeaCanadensis accumulated the highest levels of all PFAS. These species were thereafter used to investigate the effect of biomass on PFAS removal from water and for the enzyme studies. The results showed that the greater the biomass per volume, the greater the PFAS removal effect. The plant-based removal of PFAS from water is mainly due to plant absorption, although degradation also occurs. In the beginning, most of the PFAS accumulated in the roots; over time, more was translocated to the shoots, resulting in a higher concentration in the shoots than in the roots. Most PFAS degradation occurred in the water; the metabolites were thereafter taken up by the plants and were accumulated in the roots and shoots. Both peroxidases and laccases were able to degrade PFAS. We conclude that wetland plants can be used for the purification of PFAS-contaminated water. For effective purification, a high biomass per volume of water is required."
