How a race for electric vehicles threatens a marine paradise
In a statement published online, Indonesia's Ministry for the Environment said: "Raja Ampat's biodiversity is a world heritage that must be protected. "We pay great attention to mining activities that occur in the area."But photographs - taken by Global Witness as part of an investigation - appear to show environmental damage already done. Aerial images show forest loss and sediment run-off into waters that are home to biodiverse coral reefs.Global Witness told the BBC that land use for mining, across multiple small islands in the archipelago, increased by 500 hectares - equivalent to about 700 football pitches - between 2020 and 2024.
Some conservationists, including the organisation Greenpeace, are concerned that the government's decision could be reversed by legal action by the mining companies. And one company that operates on Gag island, which has particularly rich deposits of nickel, has been allowed to continue its operations. The government said it would order the "restoration of the ecological impacts that occur" there.Coral reef conservationist and ecologist Dr Mark Erdmann told BBC News that he was "blown away, and so happy" about the government's decision to revoke the mining permits."This is the global epicenter of marine biodiversity," he told BBC News. Dr Erdmann has worked in Raja Ampat for more than two decades and is one of the founders of a shark rewilding project there called Reshark. He added: "It was a voice of outrage form Indonesian people that made the government pay attention."But this ecological controversy is an example of how the demand for the metals needed to power battery technology - for electric cars and other low carbon energy sources - can damage the environment.
Indonesia now accounts for more than half of the world's nickel mine production, according to a report last year by the Institute for Energy Economics and Financial Analysis.And while the beauty and biodiversity of the Raja Ampat has drawn attention to mining activity there, mining has been linked to ecological damage elsewhere too. A 2024 study by Forest Watch Indonesia found a link between the loss of forests associated with mining activity and increased local flooding and landslides.
Increasing demand for so-called critical minerals is shaping economic decisions around the world. It was the driving force for President Trump's recent executive order to jumpstart the mining of metallic nodules from the deep sea in international waters. It is a move that China has called illegal. Dr Erdmann pointed out that balancing economic growth with environmental protection was a particular dilemma for Indonesia. "It has a lot of nickel - one way or the other, some of it's going to come out of the ground," he said. Dr Michaela Guo Ying Lo from the University of Kent led a study in 2024 of the impact of mining on local communities in Sulawesi, the large Indonesian island that has most of the country's nickel deposits. That concluded that mining activity reduced poverty slightly, but that there was significant "worsening of environmental well-being" including increased local water and air pollution. "Indonesia is positioning itself globally in the nickel market," Dr Lo told BBC News. "But it's important not to forget what's happening locally."
Imam Shofwan, an environmental campaigner from an organisation called Jatam, based in Jakarta, told BBC News: "They say nickel is a solution to the climate crisis. But it's causing deforestation and destroying farmland."He also pointed out to the BBC that low-lying coastal areas, where some nickel deposits are found, are some of the places most vulnerable to the effects of climate change, including rising sea levels. Dr Erdmann commented: "The nickel dilemma is a horrible one. "Mining is always going to be environmentally impactful and we all tend to think that electrification is a good idea. But what is the acceptable damage that we're willing to see?" The BBC contacted the Indonesian government for comment, but did not receive a reply.

Major new assessment recognises four separate giraffe species for the first time
A new assessment has concluded there are four distinct giraffe species, overturning the classification of the world's tallest land mammal as a single species. The review of giraffes was described as 'vital' by scientists at the International Union for Conservation of Nature (IUCN) who conducted the work, to better assess their conservation status and target action to protect them. Historically, giraffes have been classified as a single species with nine subspecies, but there has long been uncertainty over their taxonomy – the way in which plants, animals and microorganisms are named, described and classified. There is also an urgent need for better conservation planning for giraffes, which are assessed as 'vulnerable' to extinction on the IUCN's Red List of Threatened Species amid declining numbers, with several of the existing subspecies classified as endangered or even critically endangered. A taxonomic review by an IUCN task force assessed genetic data, which showed DNA with large differences between several giraffe lineages, supporting the recognition of different species, the experts said. The review also looked at notable differences such as skull structure and bone shape across regions and natural features such as a major rivers, rift valleys and desert areas in Africa that could have cut off giraffe populations from each other so they evolved into different species. As a result of the assessment, four distinct giraffe species have been officially recognised, with several recognised subspecies. Experts said it would lead to a more nuanced understanding of the conservation threats and opportunities they face in the diverse regions of Africa in which they live. The IUCN's Michael Brown, one of the co-authors of the assessment, said: 'This landmark taxonomic revision by the IUCN giraffe and okapi specialist group reflects the best available science and provides a globally standardised framework to inform conservation. 'Recognising these four species is vital not only for accurate IUCN Red List assessments, targeted conservation action and co-ordinated management across national borders. 'The more precisely we understand giraffe taxonomy, the better equipped we are to assess their status and implement effective conservation strategies.' The four species are: Northern giraffe, with the subspecies West African giraffe, Kordofan giraffe and Nubian giraffe; the Reticulated giraffe; the Masai giraffe, with the subspecies Masai giraffe and Luangwa/Thornicroft's giraffe; and the Southern giraffe, with the subspecies South African giraffe and Angolan giraffe.

New project in Hastings to help the kelp
A volunteer group in Hastings has launched a project to help bring back kelp forests off the Sussex - a form of seaweed - was once abundant in the area, but by the end of the 1980s, an estimated 96% had been say a ban on bottom trawling for fish, introduced in 2021, is helping natural regrowth off areas, such as Brighton and volunteers in Hastings want to help it by growing kelp in a laboratory for planting out on the seabed. Chris Williams, founder of the Sussex Kelp Project, said: "Thirty or 40 years ago, this whole area of coastline used to have kelp and the biodiversity was amazing. There used to be sea horses, starfish, spiny spider crabs and mussel beds all the way along."That's now gone due to pollution, climate change, the warming of the oceans and bottom trawling. It's so sad to see and I just wanted to do something."Kelp can form into dense forests under the sea. It supports marine life, can act as a buffer against storms, and mitigates against climate change by absorbing carbon dioxide from the atmosphere. Educating about kelp's importance The kelp growing laboratory is being set up at the Hastings Aquarium, a popular tourist attraction. It plans to have some growing on display to help educate visitors about its supervisor Rob Gasson said: "We do a lot of work with primary school children and it's great to provide an example of real-world conservation. "We can talk about what we're actually doing out in the sea, but having a physical example here on site is a great way to get people involved and encourage them."Mr Williams said he had the support of 300 volunteers from all walks of life, including divers and scientists. "It's so encouraging to see so many people caring about our environment," he added.

WA Museum partnership with Woodside criticised as record-breaking marine heatwave decimates coral reefs
The WA Greens and the state's peak conservation body have condemned the extension of a research partnership between the Western Australian Museum and Woodside, as the state reels from a record-breaking marine heatwave that has killed corals over a 1,500km stretch of ocean. The five-year continuation of the 'longstanding collaboration', in which the gas giant supports the museum's biodiversity research along the WA coastline, would allow for further targeted research along the Gascoyne coast, according to announcements. In a post on its LinkedIn page, the museum wrote that 'to mark the milestone' Woodside was supporting free general admission to the WA Maritime Museum on Sunday 17 August for the 'Woodside Energy Open Day' and the event would feature 'family-friendly activities all about marine science' as part of National Science Week. The new deal – which extends the 28-year partnership – and the open day have been promoted in front page advertisements in WA media this week. Sign up: AU Breaking News email It has prompted fury from climate advocates and the WA Greens as it coincides with the release of research about the extent of the damage caused by a record-breaking, climate-change fuelled marine heatwave to the state's coral reefs. The heatwave, which started to build off the north-west WA coast in August 2024, has been called 'the most severe coral bleaching on record for Western Australian coral reefs'. It has left 75% of affected coral either bleached or dead, according to a group of scientists from state and federal government departments, agencies and universities who worked on this week's report. The WA Greens fossil fuels and climate action spokesperson Sophie McNeill wrote to the museum on Tuesday seeking a briefing from its director Alec Coles 'because it seems like they [the museum] don't understand the relationship between fossil fuel companies and the devastating impacts of climate change we are seeing right now on our marine environment'. 'It is so inappropriate that the WA Museum has chosen to continue its partnership with one of the world's largest fossil fuel companies as our world heritage listed coral reefs are literally dying in front of our eyes,' McNeill said. 'As one of the state's biggest polluters, Woodside should not be allowed anywhere near marine science in Western Australia given they are responsible for the current devastation we are seeing along our coastline that is so universally loved by all.' McNeill expressed concern that children visiting museums to learn about oceans were being exposed to branding from 'the very same fossil fuel giant that is contributing to the death of our coral reefs'. 'It is deeply alarming that our precious institutions here in WA are so deeply captured, just like the WA Labor government, by fossil fuel companies like Woodside,' she said. In a statement, a spokesperson from WA Museum described it as 'independent, science-led, and committed to the people and the environment of Western Australia'. The spokesperson added that WA Museum relies on 'a diverse range of funding sources – including government, competitive research grants, philanthropic contributions, and corporate support'. They continued that 'engaging constructively and transparently with industry' allowed WA Museum to expand knowledge of WA's ecosystems, 'foster dialogue between sectors' and 'ensure that decisions about environmental impact are informed by the best available science'. The Conservation Council of WA said the museum, as a state government institution, should reject the extended sponsorship arrangement. Sign up to Breaking News Australia Get the most important news as it breaks after newsletter promotion 'If there is funding required the government should show some leadership and actually put up the money and ensure that important research is still continuing,' executive director Matt Roberts said. 'So that we're not relying on the very industry that is causing our marine systems to be on the brink of collapse to fund the research into that collapse.' Roberts said the council was organising a 'requiem for our reefs' at the Maritime Museum on Sunday to highlight the 'devastating impact of Woodside's emissions on WA's coral reef system, and calling for public support to stop Australia's biggest polluter from drilling for new gas under the pristine Scott Reef in the Browse Basin'. Paul Gamblin, the chief executive of the Australian Marine Conservation Society, questioned Woodside's motives, asking'what do they seek to gain from it?' 'Particularly given the very clear evidence of the marine environment coming under increasing stress, one might imagine we're going to see more of this kind of sponsorship and public relations.' The spokesperson for the WA Museum said 'Woodside neither directs the research, nor participates in it [and] the Museum retains all intellectual property generated, other than that vested in Traditional Owners'. Woodside referred back to the company statement released last week, which said the ongoing collaboration had 'led to the discovery and description of numerous new species, and significantly increased understanding of the marine environment of Western Australia'. Chief executive Meg O'Neill said last week 'this renewed collaboration reaffirms Woodside's commitment to responsible environmental management and the ongoing discovery of WA's unique marine biodiversity'.
