The future of a proposed rocket-launch facility in South Australia is uncertain. But tensions between space exploration and conservation remain.

Overfishing and poor enforcement are just two reasons marine ecosystems are struggling to recover.
Scientists have been monitoring the reef’s health for the past 40 years.
Fibreglass is denser than seawater, and it sinks quickly and accumulates in sediments where many coastal organisms live and feed.
Defunding marine monitoring networks could jeopardise efforts to avoid losing track of the world’s oceans and their precious ecosystems, which drive the blue economy.
Seagrasses are often overlooked, but they are among the most important coastal habitats on Earth.
Farming seaweed, changing ocean chemistry, breeding corals and restoring mangroves could help fight climate change – if assessed and managed responsibly.
Commercial mining of the deep sea could begin soon. But these metals and minerals are not scarce. Mining will be harmful and the economic benefits are overstated.
Seagrass meadows, mangroves and kelp forests are carbon sinks. Restoring or protecting them addresses both biodiversity loss and the climate crisis.
New research shows how marine debris from continents across the southern hemisphere threatens Antarctica’s remote coastline and unique marine ecosystems. Foreign organisms might be hitching a ride.
Canadians are no strangers to cold winters, when everything in nature appears to be frozen solid. However, under the ice cover of lakes, many animals remain active during the winter.
Using cameras and trackers attached to Australian sea lions, we explored previously unmapped ocean habitats off the South Australian coast. The data also fed into predictive computer models.
A clever approach to restoring Australia’s native oyster and mussel reefs in Queensland’s Moreton Bay is catching on, giving community groups a way to get involved in their local patch.
Kelp seaweed spores are being grown on small rocks and waste scallop shells as part of a trial exploring how to regenerate the UK’s coastal kelp forests.
This marine ecosystem is so important it’s one of the main reasons the federal government has greatly reduced the area available for offshore wind farms in the region.
Governments all over the world are propping up overfishing. Now scientists have penned an open letter calling on trade ministers to implement stricter regulations against harmful fisheries subsidies.
Any plan to dam or extract water from some of Australia’s last wild rivers must carefully consider the consequences. Prawn, mud crab and barramundi fisheries could suffer in the Gulf of Carpentaria.
Environmental degradation of Nigeria’s Niger Delta region is causing poverty as well as food insecurity, increased crime and conflict.
The first comprehensive assessment of trends in Southern Ocean ecosystems reveals an urgent need to address climate change. The summary for policymakers can guide decision-makers.
Through regulation, enforcement and monitoring, fisheries management can lead to recoveries in shark and ray populations.
