Illegal logging and land clearing continue to eat away at the world’s largest remaining tropical rainforest. But the guardians and others like them in Brazil are pushing back.
On a summer day, da Silva and the guardians prepare to patrol the Caru River, a narrow strip of muddy water marking up the boundary of the Guajajara’s 700-square-mile forest reserve. The land is protected on paper, but it’s under constant threat.
“If we go looking in our territory, we always find illegal things going on,” da Silva says before we leave.
And sure enough, as we make our way up the river in speedboats, da Silva spots a dugout canoe on the bank on the Guajajara side. We pull up alongside it, jump out and move quickly up a narrow path into the dense forest. There are fresh machete cuts in the brush. And then we hear the sound of men’s voices coming toward us. The guardians crouch down for an ambush, their rifles loaded.
The Guardians shout commands as three boys appear, with barking dogs at their heels. Soon, the boys are kneeling, with hands behind their heads. They’re from the settlement across the river. The youngest is 14; the other two are in their 20s. They confess to cutting virgin timber to make charcoal, a valuable product in this impoverished region of Brazil.
The guardians eventually send the boys back to their homes across the river with a warning to the others: Don’t come back. “This is a war,” da Silva says. “The invaders want confrontation. The hunters, the loggers, the farmers, they’re all armed. We can die at any time.”
Da Silva isn’t exaggerating. Brazil has become the deadliest country in the world for land defenders like him, with more than 140 people killed since 2015.
And Maranhão, where the Guajajara live, is perhaps the most dangerous part of the country, with more attacks on Indigenous groups here in 2016 than anywhere else.
Just after this visit, the body of one of da Silva’s fellow guardians from an Indigenous territory just south of here was found dumped along a riverbank.
Da Silva himself says he has received dozens of death threats. But for him, it’s worth the risk.
“For the Indigenous, our wealth is the forest,” he says. “It’s not gold or whatever else is there. What we want is the forest itself.”
It’s a wealth that extends far beyond the Guajajara’s land and even the rest of the Amazon. Indigenous groups protecting their forests are providing an invaluable service for all of us: helping soften the impact of climate change.
“Fifty-six percent of the carbon dioxide we are throwing into the atmosphere is removed back to the ocean, and to the forest,” says Carlos Nobre, Brazil’s leading climatologist. “This is a tremendous ecosystem service. Very few people have a vague idea what that means, or even of its existence.”
Or the fact that deforestation may be driving the entire Amazon, and the services it provides to all of us, to an alarming tipping point. After decades of sucking up huge amounts of CO2 pollution from the atmosphere, the process seems to have stopped and maybe even reversed.
If that’s happened, or when it does, that would mean the end of one of the planet’s most powerful buffers against even more dangerous climate change.
“So, if we lose even part of that, that means that we have to find ways to remove carbon and also, to decrease emissions from fossil fuel much more rapidly,” Nobre says.
Many activists say Indigenous groups like the Guajajara are the last, best hope for saving the Amazon and other tropical forests. And there’s evidence to back that up. Numerous scientificstudies have found that the best way to protect forests is to empower the people who live in them, granting them land rights and legal standing. When Indigenous people live in the forests, deforestation rates remain low, which results in carbon sequestration and cleaner water.
But it’s a David-vs-Goliath battle. Protected Indigenous lands cover nearly a quarter of the Amazon. But powerful economic forces are testing tribes like the Guajajara’s resolve — from big ag, mining and logging — to the global demand for meat and soy.
And the extractive industries have allies in the Brazilian government. Congressman Nilson Leitão is a leader in the powerful agribusiness lobby, called the ruralistas. Leitão says Brazil shouldn’t be protecting Native lands from modern enterprise.
“Brazil’s debt with the Indian is not over land,” he says.
Under his leadership, the ruralistas and their ally, President Michel Temer, have stopped the process for creating new Indigenous reserves, defunded the agency charged with protecting the rights of Indigenous people and are pushing to open existing Indigenous territories to agribusiness and mining.
“Most Indians live on government grants. Instead, they should be able to exploit their land, and make money,” Leitão says.
Brazil’s Indigenous groups generally see this rhetoric as self-serving. And they’re fighting back.
Last spring, more than 3,000 Indigenous people descended on the capital, Brasília for a week of rallies and marches. It was the largest Indigenous mobilization in Brazil’s history.
“We’ve always lived in a war in Brazil,” says Sonia Guajajara, head of the Articulation of Indigenous Peoples of Brazil and a vice presidential candidate who helped organize the event. “The colonization period was marked by deaths, murders and extermination, and this hasn’t stopped. It requires our constant resistance.”
In the Caru Indigenous Territory, da Silva calls the regional office of the military police for backup. The guardians have discovered a possible marijuana plantation on their land.
“Confronting drug traffickers is the most dangerous kind of raid,” da Silva says.
The next day, eight heavily armed policemen arrive. It’s most likely a rare show of support, da Silva says, because an American journalist is along for the ride.
We enter the forest up the river and head up a path with assault rifles and bulletproof vests, checking for trip wires and booby traps. Before long, we find a planted field, but it’s not pot. It’s cassava, planted by land-grabbers after they cleared the trees for charcoal.
The guardians cut and burn the cassava. The forest will take decades to recover.
“Sometimes, when we see the trees cut down, we feel rage,” da Silva says. “But we also have a heart, so sometimes we pity the outsiders, too. They wrecked what they had and now they want to wreck what we have. This is why we keep fighting, so that this doesn’t happen.”
