How we can restore one million hectares of degraded land | Bernardo Strassburg | TEDxBoston
Land use is often an economic decision, one that has historically led to widespread overuse and destructive practices. A clear-cut forest harvested for the logging industry or to accommodate cattle ranching provides an immediate financial reward, but with a great ecological cost. We've lost nearly three quarters of the world's wildlife population in the last half century as human use has occupied more and more wild land. Without ecosystem restoration on a grand scale, 1 million species are threatened with extinction. This model for large-scale, cost effective ecosystem restoration brings together AI optimization, open science feedback loops, and market-driven solutions to make restoration the best economic choice, not just the ecological one. It can incentivize restoration with double digit returns for investors and improve lives of local populations. The upside is huge. For example, collectively restoring 30% of low productivity degraded land worldwide has the potential to avoid the most devastating biodiversity loss and capture significant amounts of carbon dioxide. The goals of research, policy, economics, conservation, and social justice can all be aligned with thoughtful, restorative land use practices.

- 7:21Light | Maria Wolters | TEDxFDIS YouthMaria captivated the audience with a masterful fusion of physics and introspection, framing light’s paradoxes—wave-particle duality, speed limits, and intangible mass—as mirrors to human emotion. She revealed how anxiety’s irrationality mirrors light’s enigmatic nature, reframed procrastination as perfectionism’s shadow, and championed guilt-free self-care using Oxford research on happiness and productivity. Linking light’s role in sustaining life to mental well-being, she argued that resilience, like light, thrives when balanced with rest. Her talk culminated in a powerful call to embrace complexity, proving that even cosmic mysteries hold lessons for navigating our brightest and darkest moments. Maria Wolters is a G8 student at FDIS.

- 6:47Light | Marcus Chen | TEDxFDIS YouthMarcus framed “light” as hope emerging from life’s shadows—a grandmother’s wisdom lifting him from academic despair, self-belief quieting years of paralyzing stage fright, and friends cracking his self-isolating “cocoon” of screen addiction. Through raw anecdotes—a failed math exam, a speech competition meltdown, and losing friends to digital escapism—Marcus illustrated how light isn’t just external; it’s the courage to let others in and the resolve to ignite change.

- 11:29Light | Emmy Chen | TEDxFDIS YouthEmmy redefined “light” as a metaphor for identity, weaving a journey from darkness to clarity. Recalling a train tunnel in Yunnan—where time froze in blackness—she paralleled it to life’s struggles, where “light at the end” emerges through three lenses: natural (true self, solitude), artificial (false self, societal masks), and chemical (firework-like clashes of authenticity and facade). Sharing her art class meltdown, she revealed how external validation clashed with her inner critic, only to spark growth when blended. “Let your chemicals explode,” she urged, framing life’s chaos as fleeting yet transformative sparks. With a final fireworks crescendo, Emma reminded us that even darkness guides us toward light. Emmy Chen is a G9 student at FDIS.

- 11:55Light | Emma Umemura | TEDxFDIS YouthIn a moving speech, Emma reframed "light" as more than a metaphor—its persistence, clarity, and hope forged through hardship. She shared her journey during her mother’s battle with breast cancer amid the COVID-19 lockdowns, which left her isolated, emotionally withdrawn, and clinging to masks—literal and metaphorical. Though her mother’s recovery brought relief, Emma’s own healing was slow, requiring deliberate steps to reclaim joy through family, self-discovery, and small, bright moments: music, laughter, and cherished connections. Her story reminded us that light isn’t just grand ideals—it’s in everyday sparks we choose to see, even when darkness feels overwhelming. Emma Umumera is a G9 student at FDIS.

- 4:42Light | Emily Mao | TEDxFDIS YouthEmily Mao delivered a heartfelt address at the event, weaving personal anecdotes and global examples to explore “light” as a metaphor for kindness and resilience. Drawing parallels between the animated film The Wild Robot, her piano mentor Alex, and activist Dolores Huerta, she illustrated how perseverance and compassion can illuminate paths for others. Her speech highlighted the transformative power of small acts—like a neighbor’s encouragement or a leader’s advocacy—to inspire hope and drive change. Emily concluded with a rallying call for attendees to embody these values, urging them to “shine brightly” by paying forward the light they receive. Emily Mao is a G3 student at FDIS.
