The climate crisis has many consequences – among them widespread health impacts that will lead to immense societal, ecological, and economic harm.
Over the past two decades multiple large-scale reviews on climate change and health have made clear the need for a multi-sectoral approach to target t...he drivers and impacts of climate change, biodiversity loss, and ecosystem degradation. Despite this abundance of scientific evidence underscoring urgency of action, policy implementation responses lag behind. Even at COP26, itself delayed due to an ongoing pandemic, health continues to be considered by many countries a problem independent from climate and environment.

Human use of land has been transforming Earth's ecology for millennia. From hunting and foraging to burning the land to farming to industrial agriculture, increasingly intensive human use of land has reshaped global patterns of biodiversity, ecosystems, landscapes, and climate. This review examines ...recent evidence from archaeology, paleoecology, environmental history, and model-based reconstructions that reveal a planet largely transformed by land use over more than 10,000 years. Although land use has always sustained human societies, its ecological consequences are diverse and sometimes opposing, both degrading and enriching soils, shrinking wild habitats and shaping novel ones, causing extinctions of some species while propagating and domesticating others, and both emitting and absorbing the greenhouse gases that cause global climate change. By transforming Earth's ecology, land use has literally paved the way for the Anthropocene.

Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

Climate change refers to long-term shifts in weather conditions and patterns of extreme weather events. It may lead to changes in health threat to human beings, multiplying existing health problems. This review examines the scientific e...vidences on the impact of climate change on human infectious diseases. It identifies research progress and gaps on how human society may respond to, adapt to, and prepare for the related changes. Based on a survey of related publications between 1990 and 2015, the terms used for literature selection reflect three aspects — the components of infectious diseases, climate variables, and selected infectious diseases. Humans' vulnerability to the potential health impacts by climate change is evident in literature. As an active agent, human beings may control the related health effects that may be effectively controlled through adopting proactive measures, including better understanding of the climate change patterns and of the compound disease-specific health effects, and effective allocation of technologies and resources to promote healthy lifestyles and public awareness. The following adaptation measures are recommended: 1) to go beyond empirical observations of the association between climate change and infectious diseases and develop more scientific explanations, 2) to improve the prediction of spatial–temporal process of climate change and the associated shifts in infectious diseases at various spatial and temporal scales, and 3) to establish locally effective early warning systems for the health effects of predicated climate change.

Objectives: This paper reviews the mental health policies that have been implemented in Chile in response to the COVID-19 pandemic and the international context of countries' responses. Even before the start of the pandemic, there were significant barriers to access mental health services in Chile, ...coupled with a scenario of nationwide social unrest and protests that questioned the legitimacy of public institutions; now the rapidly worsening outbreaks of COVID-19 are exacerbating the pre-existing mental health crisis.
Methods: We conducted a bibliometric and content analysis of the Chilean mental health public policies implemented during the COVID-19 pandemic and then compared these policies with international experiences and emerging scientific evidence on the mental health impact of pandemics.
Results: Our analysis of the policies identifies five crucial points of action developed in Chile: (i) an established framework to address mental health in emergency and disaster situations; (ii) a timely COVID-19 Mental Health Action Plan; (iii) inclusion of mental health in the public health agenda; (iv) development of a presidential strategy during the pandemic for comprehensive mental health and well-being; and (v) emerging research assessing the mental health implications of COVID-19.
Conclusions: In Chile, the public policy responses to address the mental health consequences of the COVID-19 pandemic has been characterized by the coordinated implementation of mental health plans, ranging from a health sectoral initiative to inter-agency and intersectoral efforts. However, it is imperative that increased funding is allocated to mental health, and efforts should be made to promote the participation of people with lived experiences and communities in the design and implementation of the proposed actions. This aspect could be of key importance to social peace and community recovery after the pandemic.

The Committee discussed the implications for preparedness for smallpox-like events reflected by the ongoing COVID-19 pandemic. The Committee noted how quickly diagnostics and vaccines could be developed and deployed when resources and political will were abundant. This rapidity was also due to the f...act that the genetic sequence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had been shared worldwide. It was noted that in one country SARS-CoV-2 had been reconstructed in a laboratory from the viral genome sequence before the first case of COVID-19 had been reported, highlighting the benefits of synthetic biology technologies for accelerated development of diagnostics as well as the oft-described potential risks. Lessons learned about clinical care during the COVID-19 pandemic were also discussed.

Many commercial actors use a range of coordinated and sophisticated strategies to protect business interests— their corporate playbook—but many of these strategies come at the expense of public h...ealth. To counter this corporate playbook and advance health and wellbeing, public health actors need to develop, refine, and modernise their own set of strategies, to create a public health playbook. In this Viewpoint, we seek to consolidate thinking around how public health can counter and proactively minimise powerful commercial influences.
