Finally, we did it. Some 4.6 billion years after the hydrogen molecules first smashed together deep within the sun, scientists at the Lawrence Livermore National Laboratory in California succeeded in creating a controlled nuclear fusion reaction that produced more energy than lasers delivered to it.
You can see the appeal of the idea: instead of immediately cutting our use of oil, coal, natural gas, and other fossil fuels, we wean ourselves off gradually, stashing their planet-warming CO2 emissions underground until we figure out how to kick our addiction.
Every year, 20 million tonnes of sargassum seaweed washes up on the shores of the Caribbean, coating beaches, disrupting tourism, and releasing gases into the atmosphere. While Mexico receives the lion’s share of this toxic flotsam, countries from Brazil to Puerto Rico and even Turkey are reckoning with annual sargassum seaweed blooms.
Warming temperatures, ongoing drought, and urban sprawl are forcing the world to confront one of the oldest technologies: fire. In the modern era, instead of trying to understand wildfire, studying our vulnerabilities to it, and changing our behaviour, we have kept doing the same things, assuming water and fire retardant will solve the problem.
As internet use grows and energy consumption balloons, small changes in our digital habits could in aggregate result in a seismic reduction in global carbon output. The following are easy, actionable tips to reduce your digital carbon footprint and lower your energy bill along the way.
When Sebastián Sajoux founded Arqlite in 2015, he wanted to confront one of humanity’s most pressing problems: plastic pollution. The Argentinian entrepreneur realized that if he could add value to the more than 90 per cent of plastic that goes unrecycled, he could motivate companies to reroute packaging on an enormous scale.
If you’ve been to the beach lately—or gazed at the roadside, walked through a typical downtown, or been pretty much anywhere on the planet—you’ve no doubt noticed the world has a bit of a plastic problem: there’s too much of it. So much so that scientists estimate the mass of all plastic ever produced now surpasses that of all creatures on the planet.
While the historical plastic recycling rate hovers around 10 per cent, eco-conscious brands and individuals are striving to cut out plastic entirely—a Herculean task in the modern world. A new framework promises a provisional solution: plastic neutrality.
A nascent renewable technology called wave energy provides an enticing solution. When the sun goes down or the wind stops blowing, coastal communities could rely on the constant movement of the ocean to power their cities.
