Our reliance on unsustainable animal proteins strains the Earth. Insect protein offers a vital, sustainable alternative, rich in essential amino acids and fiber, and free of toxins. Though not a common culinary choice, embracing insect-based diets is crucial for planetary health.

Dr. Ilga Gedrovica, an award-winning food quality expert and associate professor, leads research into this future. She explores how various insects and larvae can meet dietary needs, analyzing global market trends to identify Latvia's potential contributions. Her work challenges traditional food perceptions for a more sustainable future. Learn more at ted.com/tedx.

Composer Platon Buravickis explores communication through electrical signals in his piece, "Entrance to the Universe." Created for piano, modular synthesizer, and computer electronics, the work examines how signals and waves transmit meaning between diverse entities—human, natural, or electronic—meeting to oscillate, modulate, and form unique characteristics.

A contemporary classical composer, pianist, and improviser, Buravickis studied under PÄ“teris Vasks and Selga Mence. His diverse output spans traditional symphonic and chamber music, alongside electro-acoustic works utilizing musique concrète and virtual instruments. Notable pieces include "Injector" for the Berlin Philharmonic Sharoun Ensemble and "Aesthetics of Disassembly," which he presented at a TEDx event. Learn more at https://www.ted.com/tedx.

Handwashing effectively combats coronavirus through a two-pronged attack. The virus possesses a weak outer membrane, which proper handwashing technique, especially with soap, breaks apart. Soap's unique hydrophobic and hydrophilic properties allow it to grab onto the virus and then be rinsed away by water, removing the virus from your hands. Washing for at least 20 seconds is crucial for this process.

Dr. Kate Biberdorf, a scientist and professor at the University of Texas, explains this mechanism. Known for her engaging approach to science, Dr. Biberdorf is also the author of *Kate the Chemist: The Big Book of Experiments*, available here.

Scientists have long studied climate change; now, the focus must shift to implementing solutions. As a technologist, I see immense potential for innovation to mitigate warming impacts—from preventing deforestation and preserving biodiversity to ensuring food security. The ambitious goal, central to "Operation Earth," is to leverage technology not just to limit warming, but to reverse damage and reduce global temperatures by one degree Celsius.

This urgent call to action comes from Daniela Rus, Director of MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and a distinguished professor. Her expertise in robotics and data science highlights the innovative approaches required. This talk was delivered at a TEDx event, which you can learn more about here.

Addressing the climate crisis effectively requires bipartisan political action. While once a non-partisan issue, it became a partisan wedge by the mid-1990s. Despite this, growing agreement on climate change's reality exists among Republicans and Democrats, though concerns about economic impact and individual choices persist. Policies, such as requiring companies to pay for greenhouse gas emissions, could drive immediate behavioral change.

Daniel C. Esty, a Yale professor and former EPA official, stresses that transformative change for a sustainable future demands broad political consensus, ideally around 70% support. He anticipates the Republican party will reposition itself on climate change, moving beyond past concerns about policy implications to embrace "up the middle" strategies, as explored in his book, *[A Better Planet: 40 Big Ideas for a Sustainable Future](https://amzn.to/2PpH39K)*.
