The Download: waiting at the US border, and seaweed’s carbon capture shortcomings

This is today's edition ofThe Download,our weekday newsletter that provides a daily dose of what's going on in the world of technology.

The new US border wall is an app

Keisy Plaza, 39, left her home in Colombia seven months ago. She walked a 62-mile stretch of dense mountainous rainforest and swampland with her two daughters and grandson to reach Ciudad Juarez in Mexico, on the border with Texas.

Plaza has been trying every day for weeks to secure an appointment with Customs and Border Protection (CBP) so she can request permission for her family to enter the US.

So far, she's had no luck: each time, she's been met with software errors and frozen screens. When appointment slots do open up, they fill within minutes.

Plaza has not been the only one to encounter this new obstacle. At the start of this year, President Biden announced that people at the southern border who want to seek asylum in the US must first request an appointment to meet with an immigration official via a mobile app.

The app, called CBP One, is one of just a handful of legal pathways for people seeking protection to enter the US. And no one knows how long their wait will be. Read the full story.

Seaweed farming for carbon dioxide capture would take up too much of the ocean

What's the news?: Projects focused on growing seaweed to suck CO2 from the air and lock it in the sea have attracted a lot of attention, but farming enough seaweed to meet climate-change goals may not be feasible after all.

Why not? A new study suggests that around a million square kilometers of ocean would need to be farmed in order to remove a billion tons of carbon dioxide from the atmosphere over the course of a year. That might sound a lot, but many scientific models suggest we should be removing anything from 1.3 billion tons of carbon dioxide each year to 29 billion tons by 2050 in order to hit targets.

The big story

Money is about to enter a new era of competition

April 2022

To many, cash now seems largely anachronistic. People across the world commonly use their smartphones to pay for things. This shift may look like a potential driver of inequality: if cash disappears, one imagines, that could disenfranchise the elderly, the poor, and others.

In practice, though, cell phones are nearly at saturation in many countries. And digital money, if implemented correctly, could be a force for financial inclusion.

The big questions now are around how we proceed, and whether the huge digital money shift ultimately benefits humanity at large-or exacerbates existing domestic and global inequities. Read the full story.
