Jack Schlossberg is breaking his silence on the untimely death of his sister, Tatiana Schlossberg. Jack, 32, took to Instagram on Monday, January 5, to share a tribute for his late sister. The post included several inspirational quotes, including one from Tatiana herself. "It's up to us to create a country that takes seriously its obligations to the planet, to each other and to the people who will be born into a world that looks different than ours has for the last 10,000 years or so," Tatiana wrote in her 2019 book, Inconspicuous Consumption.
