In the fight against climate change, trees are an ally. They suck in carbon dioxide, reducing the harmful greenhouse gases. But there’s a problem: we’re asking them to work overtime.
Trees can’t absorb enough of the carbon dioxide humanity is throwing at them unless we turn every inch of available land into a dense forest, according to Christophe Jospe, chief strategist at Arizona State’s Center for Negative Carbon Emissions.
But what if trees – or machines modelled after them – had superpowers? Artificial trees with otherworldly abilities are a great hope against climate change, since environmental experts say it’s not realistic to expect humanity to release significantly less carbon into the atmosphere. Our best bet might be to capture the excess carbon and store it or convert it into something useful, such as fuel.
