Cutting emissions alone will not be enough. To avoid the worst effects of global climate change, Heirloom CEO and co-founder Shashank Samala believes we’ll also need to pull a lot of carbon out of the atmosphere...

This week on How I Built This Lab, Shashank’s leap into climate entrepreneurship, launching the company that, in just four years, built North America’s first operational carbon capture facility. Plus, Heirloom’s novel approach to carbon removal—one tray of limestone at a time.

This episode was produced by Casey Herman with music by Ramtin Arablouei.

As co-founder of Twitter and founder of Blogger and Medium, Evan Williams literally helped change the conversation: he understood that real-time connectivity—being able to write a post and have people read it seconds later—was the future of engagement online. A Nebraska farm boy who dropped out of college, Ev ran into several business failures before starting Blogger, and—after it sold to Google—launching Twitter with Jack Dorsey and others. Ev also came to learn that he understood product better than people, a trait that would contribute to his eventual ouster as Twitter CEO. After that crushing blow, he returned to his first love by starting Medium, a blogging site for posts that are neither too short or too long.

Advice Line with Pete Maldonado of Chomps

Five years before he became a massively successful content creator, Dhar Mann was nearly broke and living in a studio apartment. It’s the kind of story he might tell in one of his videos: bite-sized, live-action morality tales that have earned 60 billion views across YouTube, Facebook, and other platforms. Raised in an Indian Sikh family, Dhar had a strong entrepreneurial drive, which led to early business success, but also a spectacular downfall when he got pulled into a Ponzi scheme. A few years after losing nearly everything, he began making short, dramatic videos that conveyed life lessons. Nobody watched at first and critics called them cheesy, but today, Dhar has a huge production studio in Burbank, where dozens of  employees make content for tens of millions of subscribers.

With over 14.5 million subscribers, Rosanna Pansino has one of the most popular baking channels on YouTube But she never would have imagined her success back in 2010 when she started making videos as a hobby. At the time, she was a working actor in Hollywood with dreams of landing a leading role, but after receiving an ultimatum from her agent, she was forced to choose between a career in traditional television or the nascent digital world of YouTube. More than a decade after her fateful choice, Rosanna has come full circle with her dreams in entertainment as she hosts her own shows on The Food Network — while continuing to post on YouTube and adding to her catalog of over 1,400 videos with more than 4.7 billion views.
