The Anthropocene epoch marks a critical phase in the history of humanity, where anthropogenic activities have profoundly impacted our planet. Alongside remarkable ecological crises, the Anthropocene worldview has raised existential questions, with a cultural and ethical discourse that recognizes the intrinsic value and calls for more responsible sustainable living. Addressing these collective challenges necessitates a broader perspective guided by a unified sense of purpose toward personal and planetary health. In this context, the role of religious leaders in shaping the social and environmental worldviews of their followers cannot be underestimated. Religious teachings provide a moral framework for promoting climate action, global ethics, the rights of Indigenous peoples, peace, and justice, and other aspects of planetary health. By examining the global ecological crises through the lens of Islam, the Religion of Nature, or Din al-Fitrah, and its environmental and spiritual teachings, we can gain valuable insights into humanity’s connection to the fabric of creation and its interaction with the world. These principles, rich in moral values, are intertwined with accountability and social cohesiveness. Therefore, the role of Muslim religious leaders considering the planetary-scale threats warrants further elucidation, recognizing that many other faiths and faith leaders can similarly contribute together for the common good.

The rise of globalization and industrialization has driven the demand for rare earth metals (REMs). These metals are widely used in various sectors of the global economy with various applications in medicine, renewable energy, electronics, agriculture, and the military. REMs are likely to remain an important part of our global future, and, as production increases, areas contaminated by REMs are expected to expand over the coming decades. Thus, triggering significant adverse environmental, animal, and human health impacts. Despite increased attention on REMs outside China in recent years, there are limited studies exploring REM production, deposits, and associated health impacts in the African context. Proper mine management, adequate safety protocols, sustainable processing methods, and waste handling systems have been identified and proposed globally; however, the nature and scale of implementing these management protocols on the African continent have been less clear. Therefore, planetary health-centered solutions are urgently needed to be undertaken by researchers, policy makers, and non-governmental actors in Africa and across the globe. This is with the overarching aim of ensuring eco-friendly alternatives and public health consciousness on REM exploitations and hazards for future generations to come. Full article

Arbovirus control depends on accurate projections of likely changes in the arthropod vector species, essential to inform local and global public health authorities. According to the WHO Assembly and the Global Vector Control Response (GVCR), by 2030, the burden of vector-borne diseases, particularly arbovirus infections, is expected to be greatly decreased. However, anthropogenic drivers, including climate change, insecticide resistance, and a lack of operational local databases for risk management of emerging and re-emerging arboviruses, hinders effective implementation plans. This article presents a statistical, mechanistic, integrated surveillance, thermal biology, and holistic framework (termed SMITH) to discuss how temperature variations affect the biological transmission, replication, extrinsic incubation period, nutritional behavior, distribution, and survival (TRENDS) of arboviruses. Future transdisciplinary research that involves knowledge translation between local and global communities is required for early detection and risk management of the growing threat posed by arboviruses for human, animal, and planetary health.

Being one of the most common foodborne protozoa worldwide, chronic toxoplasmosis caused by Toxoplasma gondii (T. gondii) could contribute significantly to the etiology of several mental disorders. The neurotropic parasite can directly influence the gut microbiota, causing inflammation with subsequent degradation of tryptophan required for parasite growth. Research in humans and animals shows that the gut microbiome is involved in the regulation of brain serotonergic pathways through the microbiota–gut–brain axis. Since the serotonin system is extensively interconnected with the body’s master clock through neuronal networks, the microbiota has been suggested as a potential mediator, fine-tuning circadian misalignment, following a reciprocal relationship with human eating patterns. Furthermore, adherence to an intermittent fasting diet can improve the serotonin biosynthesis pathway in the intestines and improve cognitive function. This review aims to explain the role of fasting in parasite-driven gut microbiome perturbation and the mechanisms by which Toxoplasma infection alters brain function. Due to its significant impact on social–economic status, diet patterns, microbiota disruption, circadian rhythm, chronic inflammation, and mental disorders, toxoplasmosis is an underestimated threat that could be prevented by simple lifestyle changes through educational actions. Furthermore, there are few research studies that address toxoplasmosis-induced mental disorders from a holistic perspective. Thus, a planetary health lens is needed to understand these correlations that directly relate to the promotion of a resilient and empathic civilization, crucial to enabling a flourishing healthy society on all scales.

Arboviruses are most prevalent in tropical and subtropical regions, where arthropods are widespread. The World Health Organization (WHO) estimated that the mortality burden of arbovirus diseases, such as yellow fever in Africa, was 84,000–170,000 severe cases and 29,000–60,000 deaths in 2013. These epidemics emphasize the urgent need for integrated control and prevention of arboviral diseases. Challenges in managing and controlling arboviral diseases in Africa are mainly attributed to poor insect vector control, insecticide resistance, and poor sanitation and solid waste management. The removal or reduction of mosquito populations amongst susceptible individuals is identified as the most effective measure to control many vector-borne diseases. Current public health needs call for efficient vector control programs and maintenance of adequate surveillance systems through the availability of trained personnel and rapid diagnostic facilities, providing an interdisciplinary response to control and mitigate the threats of emerging and re-emerging arboviruses. Furthermore, research priorities should focus on understanding the factors responsible for adaptation to other vectors, determinants of infection and transmission, and the development of high efficiency antiviral molecules or candidate vaccines. Here, we explore and review our current understanding of arboviruses of public health importance in Africa, with a focus on emerging arboviruses, their arthropod vectors, and the epidemiology of major arboviruses. Finally, we appraise the role of planetary health in addressing the threat of arboviruses and identify other priority areas of research for effective control. Full article

The ever-increasing global health impact of SARS-CoV-2—the etiological agent of coronavirus disease 2019 (COVID-19)—coupled with its socio-economic burden, has not only revealed the vulnerability of humanity to zoonotic pathogens of pandemic potential but also serves as a wake-up call for global health communities to rethink sustainable approaches towards preventing future pandemics. However, since the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) convened experts have declared that future pandemics are likely to be zoonotic in origin, it is imperative that we understand the key drivers of zoonosis such as biodiversity loss, climate change, wildlife consumption, and population mobility, as well as the scientific evidence underpinning them. In this article, we underscore the correlations of these drivers with the emergence and re-emergence of zoonosis. Consequently, we highlighted the need for multidisciplinary collaboration under the planetary health approach between researchers across the fields of environmental and human health to fill the knowledge and research gaps on key drivers of zoonosis. This is to prevent or limit future pandemics by protecting the natural systems of the Earth and its resources and safeguarding human and animal health. Full article

Rapid deforestation and unprecedented wildlife trafficking are important factors triggering the rate of zoonotic spillover from animals to humans. Consequently, this leads to the emergence and re-emergence of zoonotic infectious diseases among the human population. Deforestation is an important ecological disruption that leads to the loss of biodiversity. The loss of biodiversity results in the persistence of highest-quality hosts of zoonotic pathogens dominating the low-diversity communities, a process termed the dilution effect. Activities like intensive farming and logging that resulted in deforestation bring vulnerable people in close contact with these highest-quality reservoir hosts (wildlife). As a result of this vulnerability, there is an increased risk of spillover, leading to zoonotic infection in humans and eventually disease outbreaks during human–human transmission. One prominent example of a disease of wildlife origin is the ongoing SARS-CoV-2 (Severe Acute Respiratory Syndrome-Coronavirus 2), even though the original source has not been found. Another important factor facilitating the risk of spillover and emergence of zoonotic infectious diseases is wildlife trafficking. This involves illegal hunting and trading of wildlife and their products, which increases the risk of spillover as a result of exchange of bodily fluids and bloodmeals between humans and wildlife during the hunting and butchering of animals’ carcasses. Consequently, little or no hygiene protocol and poor handling practices during the wildlife-trade chain expose poachers, consumers, and local market sellers to the risk of zoonotic diseases. Despite the interventions on deforestation-induced spillover and wildlife trafficking-associated spillover, there are still knowledge and research gaps that need to be addressed towards preventing the outbreaks of future zoonotic infectious diseases. In response to this, there is a need for interdisciplinary and intersectoral collaborations among researchers from various fields as well as sectors in minimizing the risk of zoonotic spillover driven by deforestation and wildlife trafficking at the human–animal–environmental nexus. In addition, there is a need for integrated and unified evidence-based policy formulation that puts an end to deforestation and wildlife trafficking, especially in tropical areas such as Africa and Asia.

Increased anthropogenic activities including changes in land use and unrelenting ecosystem services related to animal husbandry, wildlife trade, and deforestation are driving the emergence of viral zoonosis. This is primarily due to human–animal interaction which is facilitating the spillover of viral zoonotic pathogens from animals (domestic and wildlife) to humans that could result in epidemics or pandemics. Scientific reports so far have revealed that viral epidemics and pandemics in recent years such as H1N1 Swine Influenza, H5N1 Avian Influenza, Ebola, Zika, Severe Acute Respiratory Syndrome (SARS), and the ongoing SARS-CoV-2 were all zoonotic, and their emergence has been linked with spillover events arising from human–animal interaction. This increased interaction and the increased spillover event could facilitate future pandemic risk, and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, “IPBES”, has declared this “the era of pandemics”. Furthermore, since future pandemics would be triggered by anthropogenic activities, we have called this “anthropopandemicene”, i.e., an era of pandemics driven by anthropogenic activities. To minimize the risk of future pandemics, it is important to prioritize the prevention of viral spillover events. Here, we outline five priority areas for global health researchers and policymakers. These areas include improvement of biosecurity at livestock farms, imposing a moratorium or strictly banning wildlife trade that poses a public health risk, conservation of biodiversity by halting deforestation, investing in community-based research for infectious disease control, and strengthening community healthcare systems in precarious ecosystems and infectious diseases hotspots. Finally, we acknowledge the efforts of other renowned global and legally binding frameworks such as IHR, the Paris Agreement, and CITES with regard to addressing the public health risk of infectious diseases, and we provide recommendations for their improvement.

Antimicrobials are compounds that impede the activities of bacteria, viruses, parasites, or fungi. Continuous antimicrobial overuse, misuse, and improper use for human, animal, and agricultural purposes are raising concerns about antibiotic residue pollution in the environment, and antibiotic resistance genes (ARGs). Because antimicrobial-resistant diseases are linked to human–-microbial ecosystems, environmental pollution from antibiotic residue and ARGs alters the makeup and diversity of human gut microbiota, putting resistance under selection pressure. This perspective proposes that antibiotic-induced microbiome depletion is linked to environmental quality and has repercussions for human health via the gut microbiome’s sensitive ecosystem. This has stimulated new global efforts and multidisciplinary, integrative approaches to addressing Antimicrobial Resistance (AMR) awareness in communities. Several academic papers published in recent years have shown that medicinal plant extracts are effective against diseases on WHO’s pathogen priority lists (PPL), such as the ESKAPE pathogens (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species). Traditional medicine, with its knowledge of medicinal plants, promises to be a valuable source of next-generation powerful antimicrobials. Examples include the recent discovery of Artemisinin, a highly active antimalarial drug derived from Artemisia annua, and the discovery of Taxol, an active chemotherapeutic drug derived from the bark of the Pacific yew, Taxus brevifolia. The connections between small and large ecosystems’ vitality, biodiversity protection, and human health have been acknowledged by Planetary Health principles. To address these intertwined concerns, a Planetary Health and Traditional Medicine approach can be adopted, and antimicrobial resistance can be addressed by expanding the screening of medicinal plants for bioactive compounds.
