Context and significance of a historic speech

1. The speech that silenced the world


Location: United Nations Conference on Environment and Development "The Earth Summit", organized by the UN, from June 3 to 14, 1992, in Rio de Janeiro, Federative Republic of Brazil.- 

Speaker: Severn Cullis-Suzuki (Member, at the time, along with Vanessa Suttie, Michelle Quigg, and Morgan Geisler, of the ECO -Environmental Children's Organization- group).-

In 1992, a 12-year-old girl named Severn Cullis-Suzuki addressed world leaders gathered at the Earth Summit in Rio de Janeiro. Her speech, known as "the speech that silenced the world," was a lucid and well-founded call to action that resonates with unusual force three decades later. Her words, imbued with a clarity that contrasts with the complexity of her message, exposed the contradictions of a model that prioritizes short-term economic gain over the sustainability of the planet and its most vulnerable inhabitants.

Severn's speech is a reminder that the environmental crisis is not just a technical problem, but an ethical and public health issue. Her voice directly challenged adults and decision-makers, questioning the coherence between what is taught to new generations and real-world actions. Below is the complete original message that moved the audience:

Speech by Severn Cullis-Suzuki at the Earth Summit, Rio de Janeiro, 1992

Hello, I’m Severn Suzuki speaking for “ECO” — the Environmental Children’s Organization. We are a group of 12 and 13-year-olds trying to make a difference: Vanessa Suttie, Morgan Geisler, Michelle Quigg, and me. We’ve raised all the money to come here ourselves — to come 5,000 miles to tell you adults you must change your ways. Coming up here today, I have no hidden agenda.

I am fighting for my future. Losing my future is not like losing an election, or a few points on the stock market. I am here to speak for all generations to come. I am here to speak on behalf of the starving children around the world whose cries go unheard. I am here to speak for the countless animals dying across this planet, because they have nowhere left to go.

I am afraid to go out in the sun now, because of the holes in our ozone. I am afraid to breathe the air, because I don’t know what chemicals are in it. I used to go fishing in Vancouver, my home, with my Dad until, just a few years ago, we found the fish full of cancers. And now we hear of animals and plants going extinct every day, vanishing forever. In my life, I have dreamt of seeing the great herds of wild animals, jungles, and rainforests full of birds and butterflies, but now I wonder if they will even exist for my children to see.

Did you have to worry about these things when you were my age? All this is happening before our eyes and yet we act as if we have all the time we want and all the solutions. I’m only a child and I don’t have all the solutions. I want you to realize, neither do you. You don’t know how to fix the holes in our ozone layer. You don’t know how to bring the salmon back up in a dead stream. You don’t know how to bring back an animal now extinct. And you can’t bring back the forests that once grew where there is now a desert. If you don’t know how to fix it, please stop breaking it.

Here, you may be delegates of your governments, business people, organizers, reporters, or politicians. But, really, you are mothers and fathers, sisters and brothers, aunts and uncles — and all of you are someone’s child.

I’m only a child, yet I know we are all part of a family — five billion strong; in fact, 30 million species strong — and borders and governments will never change that. I’m only a child, yet I know we are all in this together and should act as one single world towards one single goal.

In my anger, I’m not blind; and in my fear, I’m not afraid of telling the world how I feel. In my country we make so much waste, we buy and throw away, buy and throw away, buy and throw away and yet Northern countries will not share with the needy. Even when we have more than enough we are afraid to share; we are afraid to let go of some of our wealth.

In Canada, we live the privileged life. We’ve plenty of food, water, and shelter. We have watches, bicycles, computers, and television sets. The list could go on for two days. Two days ago, here in Brazil, we were shocked when we spent time with some children living on the streets. This is what one child told us: “I wish I was rich and if I were, I would give all the street children food, clothes, medicines, shelter, and love and affection.” If a child on the streets who has nothing is willing to share, why are we who have everything still so greedy?

I can’t stop thinking that these are children my own age, that it makes a tremendous difference where you are born; that I could be one of those children living in the favelas of Rio. I could be a child starving in Somalia, or a victim of war in the Middle East, or a beggar in India.

I am only a child, yet I know if all the money spent on war was spent on finding environmental answers, ending poverty, and in finding treaties, what a wonderful place this Earth would be.

At school, even in kindergarten, you teach us how to behave in the world. You teach us to not to fight with others, to work things out, to respect others, to clean up our mess, not to hurt other creatures, to share, not be greedy. Then, why do you go out and do the things you tell us not to do?

Do not forget why you are attending these conferences — who you're doing this for. We are your own children. You are deciding what kind of a world we are growing up in. Parents should be able to comfort their children by saying, “Everything’s going to be all right; it’s not the end of the world, and we’re doing the best we can.” But I don’t think you can say that to us anymore. Are we even on your list of priorities?

My dad always says, “You are what you do, not what you say.” Well, what you do makes me cry at night. You grown-ups say you love us. But I challenge you, please, make your actions reflect your words.

Thank you.

Severn's speech was not just a moving moment; it was an early warning based on environmental observations. Her concerns and questions, which in 1992 might have seemed like distant projections, have consolidated into a documented everyday reality. The scientific evidence accumulated over the past decades only confirms and amplifies the urgency of her message.

2. Scientific evidence: Climate change and health

Severn's message, centered on environmental degradation, biodiversity loss, and pollution, has been validated and expanded by decades of rigorous scientific research. Climate change, driven by human activity, is now recognized by the scientific community as one of the greatest challenges to global public health, affecting both the environment and the physical and mental health of people.

Systematic reviews and scoping studies in the scientific literature have shown that climate change negatively impacts mental health, exacerbating conditions such as anxiety, depression, and post-traumatic stress disorder, with more pronounced effects on vulnerable groups. Specialized literature highlights that exposure to extreme weather events and environmental deterioration generates chronic stress that affects psychological well-being at the population level.

Likewise, the impacts on physical health are widely documented. Rising temperatures and changes in precipitation patterns are associated with a higher incidence of vector-borne infectious diseases, such as dengue and malaria, as well as an increase in morbidity and mortality from extreme climate events, such as heat waves and floods. Food and water insecurity, exacerbated by these phenomena, disproportionately affects regions with fewer resources, just as Severn pointed out in her intervention.

  • Climate change and mental health: Extreme temperatures and environmental degradation increase the risks of anxiety, depression, and post-traumatic stress, especially in vulnerable populations.
  • Infectious diseases: Global warming expands the geographical areas suitable for vectors such as mosquitoes, increasing the incidence of diseases like dengue and malaria.
  • Extreme climate events: Heat waves and floods contribute directly to an increase in respiratory and cardiovascular diseases.
  • Food and water insecurity: Climate change affects food production and water quality, which increases the prevalence of diseases transmitted through these means, especially in developing regions.

These data, coming from authoritative sources such as the World Health Organization (WHO), the Intergovernmental Panel on Climate Change (IPCC), and databases like PubMed and Cochrane, confirm that the concerns expressed by Severn Cullis-Suzuki in 1992 were not speculations, but a well-founded anticipation of a crisis that is today perfectly documented and quantified by science.

3. Contemporary analysis and reflection

The enduring relevance of Severn Cullis-Suzuki's speech lies in its ability to transcend time and connect with current evidence-based concerns. What in 1992 was an early warning signal is today a confirmed scientific diagnosis. The "girl who silenced the world" remains a symbol of the need to integrate scientific knowledge with responsible political and social action.

The scientific evidence presented demonstrates that climate change is a multidimensional problem that impacts all aspects of human life. Health, both physical and mental, is at the center of this crisis. Future generations, like those Severn represented, face a landscape of growing risks that require decisive, coordinated, and data-driven actions on a global scale. Severn's call for coherence between discourse and action resonates today more strongly than ever, urging citizens, governments, and corporations to assume their responsibility with rigor and transparency.

In this context, the figure of Severn Cullis-Suzuki is not only that of an activist, but also of a scientist and educator. Following her participation in the Earth Summit, she obtained a degree in Ecology and Evolutionary Biology from Yale University in 2002, and later completed postgraduate studies in Ethnoecology at the University of Victoria, where she worked with elders of the First Nations. She has dedicated her life to scientific dissemination and the defense of the rights of nature and indigenous cultures, demonstrating that activism and academic rigor can and must go hand in hand.
