Are the Amazon Fires a Crime Against Humanity?
By Tara Smith
Fires in the Brazilian Amazon have jumped 84 percent during President Jair Bolsonaro's first year in office and in July 2019 alone, an area of rainforest the size of Manhattan was lost every day. The Amazon fires may seem beyond human control, but they're not beyond human culpability.
Bolsonaro ran for president promising to "integrate the Amazon into the Brazilian economy". Once elected, he slashed the Brazilian environmental protection agency budget by 95 percent and relaxed safeguards for mining projects on indigenous lands. Farmers cited their support for Bolsonaro's approach as they set fires to clear rainforest for cattle grazing.
Bolsonaro's vandalism will be most painful for the indigenous people who call the Amazon home. But destruction of the world's largest rainforest may accelerate climate change and so cause further suffering worldwide. For that reason, Brazil's former environment minister, Marina Silva, called the Amazon fires a crime against humanity.
From a legal perspective, this might be a helpful way of prosecuting environmental destruction. Crimes against humanity are international crimes, like genocide and war crimes, which are considered to harm both the immediate victims and humanity as a whole. As such, all of humankind has an interest in their punishment and deterrence.
Crimes against humanity were first classified as an international crime during the Nuremberg trials that followed World War II. Two German Generals, Alfred Jodl and Lothar Rendulic, were charged with war crimes for implementing scorched earth policies in Finland and Norway. No one was charged with crimes against humanity for causing the unprecedented environmental damage that scarred the post-war landscapes though.
Our understanding of the Earth's ecology has matured since then, yet so has our capacity to pollute and destroy. It's now clear that the consequences of environmental destruction don't stop at national borders. All humanity is placed in jeopardy when burning rainforests flood the atmosphere with CO₂ and exacerbate climate change.
Holding someone like Bolsonaro to account for this by charging him with crimes against humanity would be a world first. If successful, it could set a precedent which might stimulate more aggressive legal action against environmental crimes. But do the Amazon fires fit the criteria?
Prosecuting crimes against humanity requires proof of widespread and systematic attacks against a civilian population. If a specific part of the global population is persecuted, this is an affront to the global conscience. In the same way, domestic crimes are an affront to the population of the state in which they occur.
When prosecuting prominent Nazis in Nuremberg, the US chief prosecutor, Robert Jackson, argued that crimes against humanity are committed by individuals, not abstract entities. Only by holding individuals accountable for their actions can widespread atrocities be deterred in future.
The International Criminal Court's Chief Prosecutor, Fatou Bensouda, has promised to apply the approach first developed in Nuremberg to prosecute individuals for international crimes that result in significant environmental damage. Her recommendations don't create new environmental crimes, such as "ecocide", which would punish severe environmental damage as a crime in itself. They do signal, however, a growing appreciation of the role that environmental damage plays in causing harm and suffering to people.
The International Criminal Court was asked in 2014 to open an investigation into allegations of land-grabbing by the Cambodian government. In Cambodia, large corporations and investment firms were being given prime agricultural land by the government, displacing up to 770,000 Cambodians from 4m hectares of land. Prosecuting these actions as crimes against humanity would be a positive first step towards holding individuals like Bolsonaro accountable.
But given the global consequences of the Amazon fires, could environmental destruction of this nature be legally considered a crime against all humanity? Defining it as such would be unprecedented. The same charge could apply to many politicians and business people. It's been argued that oil and gas executives who've funded disinformation about climate change for decades should be chief among them.
Charging individuals for environmental crimes against humanity could be an effective deterrent. But whether the law will develop in time to prosecute people like Bolsonaro is, as yet, uncertain. Until the International Criminal Court prosecutes individuals for crimes against humanity based on their environmental damage, holding individuals criminally accountable for climate change remains unlikely.

From the mythical minotaur to the mule, creatures created from merging two or more distinct organisms – hybrids – have played defining roles in human history and culture. However, not all hybrids are as fantastic as the minotaur or as dependable as the mule; in fact, some of them cause human diseases.
When Looking Through a Microscope Isn’t Close Enough.<p>For the last few years, <a href="http://www.rokaslab.org/" target="_blank">our team at Vanderbilt University</a>, <a href="https://www.researchgate.net/lab/Gustavo-Goldman-Lab" target="_blank">Gustavo Goldman's team at São Paulo University in Brazil</a> and many other collaborators around the world have been collecting samples of fungi from patients infected with different species of <em>Aspergillus</em> molds. One of the species we are particularly interested in is <a href="https://doi.org/10.1006/rwgn.2001.0082" target="_blank"><em>Aspergillus nidulans</em>, a relatively common and generally harmless fungus</a>. Clinical laboratories typically identify the species of <em>Aspergillus</em> causing the infection by examining cultures of the fungi under the microscope. The problem with this approach is that very closely related species of <em>Aspergillus</em> tend to look very similar in their broad morphology or physical appearance when viewing them through a microscope.</p><p>Interested in examining the varying abilities of different <em>A. nidulans</em> strains to cause disease, we decided to analyze their total genetic content, or genomes. What we saw came as a total surprise. We had not collected <em>A. nidulans</em> but <em>Aspergillus latus</em>, a close relative of <em>A. nidulans</em> and, as we were to soon find out, <a href="https://doi.org/10.1016/j.cub.2020.04.071" target="_blank">a hybrid species that evolved through the fusion of the genomes</a> of two other <em>Aspergillus</em> species: <em>Aspergillus spinulosporus</em> and an unknown close relative of <em>Aspergillus quadrilineatus</em>. Thus, we realized not only that these patients harbored infections from an entirely different species than we thought they were, but also that this species was the first ever <em>Aspergillus</em> hybrid known to cause human infections.</p>
Several Different Fungal Hybrids Cause Human Disease.<p>Hybrid fungi that can cause infections in humans are well known to occur in several different lineages of single-celled fungi known as yeasts. Notable examples include multiple different species of <a href="https://doi.org/10.1002/yea.3242" target="_blank">yeast hybrids</a> that cause the human diseases <a href="https://rarediseases.info.nih.gov/diseases/6218/cryptococcosis" target="_blank">cryptococcosis</a> and <a href="https://www.cdc.gov/fungal/diseases/candidiasis/index.html" target="_blank">candidiasis</a>. Although pathogenic yeast hybrids are well known, our discovery that the <em>A. latus</em> pathogen is a hybrid is a first for molds that cause disease in humans.</p>
(Left) Candida yeasts live on parts of the human body. Imbalance of microbes on the body can allow these yeasts, some of which are hybrids, to grow and cause infection. (Right) Cryptococcus yeasts, including ones that are hybrids, can cause life-threatening infections in primarily immunocompromised people. Centers for Disease Control and Prevention<p><a href="https://doi.org/10.1371/journal.ppat.1008315" target="_blank">Why certain <em>Aspergillus</em> species are so deadly</a> while others are harmless remains unknown. This may in part be because <a href="https://doi.org/10.1016/j.fbr.2007.02.007" target="_blank">combinations of traits, rather than individual traits</a>, underlie organisms' ability to cause disease. So why then are hybrids frequently associated with human disease? Hybrids inherit genetic material from both parents, which may result in new combinations of traits. This may make them more similar to one parent in some of their characteristics, reflect both parents in others or may differ from both in the rest. It is precisely this mix and match of traits that hybrids have inherited from their parental species that <a href="https://www.nytimes.com/2010/09/14/science/14creatures.html" target="_blank">facilitates their evolutionary success</a>, including their ability to cause disease.</p>
The Evolutionary Origin of an Aspergillus Hybrid.<p>Multiple evolutionary paths can lead to the emergence of hybrids. One path is through mating, just as the horse and donkey mate to create a mule. Another path is through the merging or fusion of genetic material from cells of different species.</p><p>It is this second path that appears to have been taken by our fungus. <em>A. latus</em> appears to have two of almost everything compared to its parental species: twice the genome size, twice the total number of genes and so on. But unlike other hybrids, which are often sterile like the mule, we found that <em>A. latus</em> is capable of reproducing both asexually and sexually.</p><p>But how distinct were the parents of <em>A. latus</em>? By comparing the parts contributed by each parent in the <em>A. latus</em> genome, we estimate that its parents are approximately 93% genetically similar, which is about as related as we humans are with lemurs. In other words, <em>A. latus</em>, an agent of infectious disease, is the fungal equivalent of a human-lemur hybrid.</p>
How A. Latus Differs From its Parents.<p>Elucidating the identity of closely related fungal pathogens and how they differ from each other in infection-relevant characteristics is a key step toward reducing the burden of fungal disease. For example, we found that <em>A. latus</em> was three times more resistant than <em>A. nidulans</em>, the species it was originally identified as using microscopy-based methods, to one of the most common antifungal drugs, <a href="https://www.drugbank.ca/drugs/DB00520" target="_blank">caspofungin</a>. This result provides a clear example of the potential importance of accurate identification of the <em>Aspergillus</em> pathogen causing an infection.</p><p>We also examined how <em>A. latus</em> and <em>A. nidulans</em> interact with cells from our immune system. We found that immune cells were less efficient at combating <em>A. latus</em> compared to <em>A. nidulans</em>, suggesting the hybrid fungus may be trickier for our immune systems to identify and destroy.</p><p>In the midst of the COVID-19 pandemic, our quest to understand <em>Aspergillus</em> pathogens is becoming more urgent. Growing evidence suggests that <a href="https://doi.org/10.1111/myc.13096" target="_blank">a fraction of COVID-19 patients are also infected with <em>Aspergillus</em>.</a> More worrying is that these <a href="https://doi.org/10.3201/eid2607.201603" target="_blank">secondary <em>Aspergillus</em> infections</a> can worsen the clinical outcomes for those infected with the novel coronavirus. That being said, we stress that little is known about <em>Aspergillus</em> infections in COVID-19 patients due to a lack of systematic testing, and none of the infections identified so far appear to have been caused by hybrids.</p><p>So, when it comes to hybrids, some are fantastic (the minotaur), some are helpful (the mule) and some are dangerous (<em>Aspergillus latus</em>). Understanding more about the biology of <em>Aspergillus latus</em> may help in our understanding of how microbial pathogens arise and how to best prevent and combat their infections.</p>

World Environment Day: A Time to Consider the Planet We’ll Return To, and Decide How to Care for It Going Forward
It's a different kind of World Environment Day this year. In prior years, it might have been enough to plant a tree, spend some extra time in the garden, or teach kids the importance of recycling. This year we have heavier tasks at hand. It's been months since we've been able to spend sufficient time outside, and as we lustfully watch the beauty of a new spring through our kitchen's glass windows, we have to decide how we'll interact with the natural world on our release, and how we can prevent, or be equipped to handle, future threats against our wellbeing.
