While marine researchers are excited about the promise the mapping project holds for science, many fear that a map of our sea floor will enable extractive industries to profit from deep sea resources, endangering marine habitats and coastal communities in the process.

Across the country, the growing popularity of mountain biking is increasingly a threat to our wildlands, even in designated wilderness. Some mountain biking advocates promote the idea that their sport is compatible with the goals, and even the legal obligations of federal land management agencies that manage wilderness.

Yet my feeling is that mountain bikers and their machines are a threat to the legal, ecological, and philosophical foundations of the Wilderness Act and public lands management. I say this as someone who regularly rides a mountain bike.

That pollution is bad for our health will come as a surprise to no one. That pollution kills at least 9 million people every year might. This is 16 percent of all deaths worldwide – 3 times more than AIDS, tuberculosis and malaria combined, and 15 times more than all wars and other forms of violence. Air pollution alone is responsible for 6.5 million of these 9 million deaths. Nearly 92 percent of pollution-related deaths occur in low- and middle-income countries. All this is according to the Lancet Commission on Pollution and Health, a recent report by dozens of public health and medical experts from around the world. This important report is sounding the alarm about a too-often neglected and ignored ‘silent emergency’ – or as author Rob Nixon calls it, ‘slow violence.’

Activists from Australia and beyond are joining forces to prevent what is set to be one of the world’s biggest ecological catastrophes. The massive Carmichael coal mega-mine will devastate the Great Barrier Reef, contribute massively to global climate change, and further marginalise Australia’s First Nations people.

Far from bringing about an ecological transition, allowing the ruling class to gain control of the global thermostat would more likely result in new commodity frontiers and capitalist expansion, along with the development of new weapons to be used against opponents of empire – as the US attempted in Vietnam through weather modification. A review of the most prominent geoengineering technologies reveals that the impacts of deployment would disproportionately fall on peasant and poor communities in the Global South. Socialist support for geoengineering would be a striking reversal for a political tradition based on international solidarity with the oppressed and exploited.

People yearn for alternatives to industrial agriculture, but they are worried. They see large-scale operations relying on corporate-supplied chemical inputs as the only high-productivity farming model. Another approach might be kinder to the environment and less risky for consumers, but, they assume, it would not be up to the task of providing all the food needed by our still-growing global population.

Only one country comes even close to delivering the good life in a sustainable way: Vietnam succeeds on six social indicators — including a life expectancy above 65 years and providing sufficient nutrition — while staying within its limit on every environmental threshold except carbon emissions.

Since last August, protesters have occupied facilities associated with two open-pen fish farming sites, both of which are up for relicensing in June. The facilities, operated by Norwegian company Marine Harvest, are located on Swanson Island and Midsummer Island in the Broughton Archipelago in northern British Columbia, an important wild salmon migratory route. Occupiers are sending a clear message to government they want their rights as Indigenous people upheld and the licenses cancelled.
