New discoveries have been made about baleen whales, northern elephant seals, and the diet of a deep-sea isopod species. The diet of microbes has also been found to influence the effectiveness of carbon sequestration in the deep ocean. 

 

Fisheries 

It has been revealed that 200,000 birds are caught as bycatch from fisheries in Europe each year.  

The Scottish Government has spoken on its commitment to tackling modern slavery within Scotland’s fishing industry. The welfare of fishers on vessels fishing for ‘ecolabeled tuna’, and those in Indonesia has been revealed.

Conservation 

Salmon habitats are being restored by tribes in Washington, and there are rebounding sand tiger shark populations in Boston. 

Foreign Secretary, David Lammy, met with Sir David Attenborough to discuss Labour’s vision for nature and climate, and Minister of State for FCDO, Stephen Doughty, describes the UK Blue Belt Programme as the ‘world’s largest marine conservation network!’

Marine Protection 

Over 80% of the EU’s Marine Protected Areas (MPAs) have been shown to be ‘ineffective’. 

Indonesia’s revised conservation law fails to mention marine and fisheries issues.

Climate Crisis 

Concerns have been raised about climate change by a new study which has revealed that ‘6% of the total uptake of carbon dioxide by the ocean is due to rainfall’. Antarctic sea ice has declined to a record low for a second year, impacting on seabird’s food supply, and methane emissions continue to be rising whereby two-thirds come from human activity. Additionally, rising nitrogen levels from human waste have been found to increase the likelihood of toxic algal blooms. 

Brazil has urged the EU not to go ahead with their new law which is aimed at banning imports of products which are driving deforestation. 

Are rich countries silencing climate protesters? Almost 200 people were killed trying to defend the environment last year, and the EU is using ‘harsh, overly broad laws’ to silence them.
