Across the Americas, it is becoming harder to draw the lines that once seemed so clear.

Agricultural regions in the United States increasingly depend on migrant labor moving through transnational corridors that stretch from Central America to the Pacific Coast. Lithium extracted in the highlands of South America now sits at the center of global supply chains powering electric vehicles in North America and Europe. Communities across the United States are confronting housing instability, informal economies, and environmental conditions that were once described as problems of the “developing world.” At the same time, cities across Latin America are deeply embedded in global financial networks, technology industries, and logistics systems that operate at planetary scale.

The map that once divided the world into the Global North and the Global South is becoming harder to recognize.

For many years, that language helped people understand the hierarchies that shaped the twentieth century. Earlier generations used a similar frame when they spoke of the First, Second, and Third Worlds. These maps named real patterns of power and inequality.

One of the most powerful images from that earlier period came from the idea of the open veins of Latin America — a way of describing how wealth flowed outward from the lands and peoples of the region toward distant centers of power. The metaphor captured something real. For centuries, silver, sugar, rubber, coffee, oil, and human labor were drawn from the Americas to enrich imperial economies elsewhere.

But the terrain we are living in today no longer follows that simple map.

The veins that earlier generations described have not closed. In many places they remain painfully open. What has changed is the structure of the system around them.

Across the hemisphere, systems that once appeared separate increasingly operate through shared pathways. Migration routes, supply chains, extraction economies, financial networks, and enforcement infrastructures now link multiple countries simultaneously. These pathways function as corridors of circulation through which people, goods, capital, and power move continuously across borders.

Where several of these corridors intersect, their pressures accumulate. Migration meets enforcement. Supply chains meet labor displacement. Extraction economies meet ecological collapse. In these places, forces that once appeared separate become visible as parts of the same system.

I have begun to think of these places as the seam.

The seam is where the hemisphere reveals itself most clearly — where forces that once appeared separate such as war, migration, drugs, policing, climate disruption, and economic displacement become visible as parts of the same terrain.

Communities living along the seam often recognize these connections earlier than others, not because they possess special information but because the consequences arrive there first. For them, the hemisphere is not an abstract geopolitical idea. It is an everyday condition.

For me, this way of seeing the hemisphere has been shaped by where I have lived. I grew up in La Lima, Cortés, in the colonia SITRATERCO in Honduras — a place shaped by the banana economy, labor struggles, migration, U.S. corporate power, and repeated flooding that made clear very early how climate vulnerability and economic vulnerability are often lived together. Later in life I moved through cities in the United States such as New Orleans, Boston, Buffalo, Washington, DC, Durham, and Richmond, California. These are very different places, but they share something important: they are places where multiple systems intersect and where the pressures of the hemisphere become visible in everyday life.

Living across these environments taught me something that I have been saying for decades: there is a Global South inside the Global North, and a Global North inside the Global South.

Because I have lived much of my life in the seams of the hemisphere, that idea always felt obvious to me. Yet for many years I found myself in philanthropic and institutional spaces where the world continued to be described through the language of the Global North and Global South as if those were stable and separate realities. That description never matched the terrain I knew.

At the same time, in many of my interactions with movements in what is often described as the Global South, I have also experienced a different kind of invisibility. The assumption is often that because I have spent many years working and living in the United States, I must have lived a Global North life all along. In reality, that could not be further from the truth. Much of my life has unfolded in places where the pressures of the hemisphere are most visible and where the boundaries between North and South blur in everyday experience.

What we are witnessing today is not simply the emergence of new crises, but the widening of the seam itself. Pressures that once appeared confined to particular regions or communities are increasingly visible across the hemisphere. Migration, ecological disruption, economic precarity, and policing no longer remain contained within distant geographies. They travel along the same corridors that move labor, capital, and resources.

As these pressures circulate, more places begin to experience the seam.

Yet the seam does not appear everywhere equally.

Alongside the corridors that move resources, labor, and power across the hemisphere, and the seams where their pressures converge, there are also layers of insulation. Through wealth, institutional distance, legal protection, and geographic privilege, many actors remain buffered from the consequences those systems produce. In many cases they also benefit from the same systems that generate instability elsewhere. Resources, profits, and security accumulate in some places even as the pressures of migration, extraction, environmental damage, and economic displacement are absorbed in others. Decisions can be made far from where their effects are most deeply felt.

When people experience only one part of a larger structure of harm, it becomes easy to misidentify the source of the problem. Communities may come to see one another as the cause of instability rather than recognizing the broader systems shaping their lives. This is one of the ways division takes root.

But when the terrain becomes visible, something else becomes possible.

Many of the pressures people are experiencing — the displacement driving migration, the economic precarity spreading across working communities in the United States, and the ecological devastation affecting lands across the Americas — are not isolated problems. They are different consequences of the same systems moving through the same corridors.

Once that becomes visible, solidarity stops being only a moral appeal. It becomes a practical recognition of the terrain we now share.

If Galeano helped a generation understand the open veins of Latin America, the moment we are entering may be better understood through corridors, seams, and insulation.

If this interpretation of the hemisphere is even partially correct, it has implications not only for governments and movements, but for institutions of every kind. Strategies designed for a world divided neatly between North and South may struggle to respond to a terrain organized through corridors, seams, and insulation.

The challenge ahead is not simply how to intervene in isolated crises, but how to recognize and act responsibly within the larger systems that are producing them.

Much of the work we are exploring through Poetic Futurism begins from this recognition: that the future of the Americas will depend on our ability to see the terrain we now share.
