I’m only 41 years old. To some of y’all, that’s young and a great age for a leader of the biggest grassroots environmental organization in Texas and the country. To others, whether my six year old daughter or the many teenage and twenty-something activists and organizers fighting for climate justice across Texas, I’m an old dude who talks too much about how great it was when…you know what I mean.

I have much to learn, and yet I’ve learned so much. 

We are living in unprecedented times, marked by uncertainty, division, and deep challenges. The realities we face—whether political, social, or environmental—can feel overwhelming, and the path forward is often unclear. In moments like these, when fear and worry threaten to take hold, I turn to four core values that ground me and guide my actions: family, history, our connection to the land, and the power we hold collectively to shape a better future.

Family grounds me every morning and night as I listen to the hope-filled and innocent sounds and stories from my daughter that help me paint a picture of her future and how I must organize to fight for it with every ounce of my energy. History in the form of learning from my elders, and opening space for both my generation and younger generations to learn about mass deportations in the 1950s under President Eisenhower, or how the first Earth Day arose not as a call by siloed environmentalists, but one of people across issue bases united for a liveable planet. The touch of Texas wind, warm sun, and soft soil reminds me to breathe, and connects me with the living spirit of my ancestors who navigated poverty, hardship, and racism in ways I’ve not come close to, but their endurance lives in me. 

This year has been difficult in countless ways, testing our resilience and resolve over and over. And after 24 years of single-party rule in Texas, we’ve faced decades of challenges to human, social, women’s, and environmental rights. Yet, through it all, we’re still here. We’re still organizing. We’re still working tirelessly for a better future for our people, communities, and families.

That work is bearing fruit, and as we gear up for a 2025 that will be riddled with attacks on our values from both the state and federal government, we must remember that we’ve been here before. Our people have been here before. But to do more than to survive, to really grow and thrive, our mission must be to cultivate networks of intergenerational power - young and old - where leadership is shared and ceded, and hope is tended to like the flowers and plants in our gardens.

Keep the faith, get your friends and family to join the Sierra Club Lone Star Chapter, and get involved to help build on successes like these:

Looking for some more inspiration and hope? Watch this video from El Paso Matters documenting the release of several dozen big horn sheep into Franklin Mountains State Park. My father, Tony Cortez, was one of about 300 people there to witness this release. This is special. Three generations of my family and countless friends have walked, hiked, scrambled, and climbed these lands, and to see wildlife return with such vibrant enthusiasm touches your soul.

Those are just a few of the bright spots of 2024. I’m most excited about the infrastructure we’re building to help you, your family, and your friends plug into organizing in your own backyard and in networks across Texas. Be sure to check out our Keep The Power On Campaign if you’re interested in energy, electricity, and modernizing our electric grid, and consider the Water For People and the Environment Committee to help keep pollution out of our waterways and to ensure we have water in the decades to come.

Together, we have everything to gain.
Together, we can defend our values and our neighbors.

Together, we can build the power to win big change right here in Texas.

With love, gratitude, and hope,
