Plastic pollution is ubiquitous throughout the marine environment, yet estimates of the global abundance and weight of floating plastics have lacked data, particularly from the Southern Hemisphere and remote regions. Here we re...port an estimate of the total number of plastic particles and their weight floating in the world's oceans from 24 expeditions (2007–2013) across all five sub-tropical gyres, costal Australia, Bay of Bengal and the Mediterranean Sea conducting surface net tows (N = 680) and visual survey transects of large plastic debris (N = 891). Using an oceanographic model of floating debris dispersal calibrated by our data, and correcting for wind-driven vertical mixing, we estimate a minimum of 5.25 trillion particles weighing 268,940 tons. When comparing between four size classes, two microplastic <4.75 mm and meso- and macroplastic >4.75 mm, a tremendous loss of microplastics is observed from the sea surface compared to expected rates of fragmentation, suggesting there are mechanisms at play that remove <4.75 mm plastic particles from the ocean surface.

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.

The global prevalence, morbidity and mortality related to childhood asthma among children has increased significantly over the last 40 years. Although asthma is recognized as the most common chronic disease in children, issues of underdiagnosis and undertreatment persist. There are substantial globa...l variations in the prevalence of asthma symptoms in children, with up to 13-fold differences between countries. The rising number of hospital admissions for asthma may reflect an increase in asthma severity, poor disease management and/or the effect of poverty. The financial burden of asthma is relatively high within developed countries (those for which data is available) spending 1 to 2% of their healthcare budget on this condition. Established in 1989, the Global Initiative for Asthma (GINA) attempts to raise awareness about the increasing prevalence of asthma, improve management and reduce the burden of asthma worldwide. Despite global efforts, GINA has not achieved its goal, even among developed nations. There are multiple barriers to reducing the global burden of asthma, including limited access to care and/or medications, and lack of prioritization as a public healthcare priority. In addition, the diversity of healthcare systems worldwide and large differences in access to care require that asthma management guidelines be tailored to local needs.

The threat posed by Zika virus infection highlights the need to reinforce preparedness arrangements for mosquito-borne diseases in EU/EEA countries, especially for pathogens transmitted by Aedes aegypti and Aedes albopictus.
The aim of this document is to highlight measures that can effectively red...uce the risk of importation and local transmission of pathogens transmitted by Ae. aegypti and Ae. albopictus. The main diseases of concern in this context are Zika, dengue, chikungunya and yellow fever.

Background: The impacts of air pollutants on health range from short-term health impairments to hospital admissions
and deaths. Climate change is leading to an increase in air pollution.
This report compiles data for the first time on the far-reaching consequences of uncontrolled hypertension, including heart attacks, strokes and premature death, along with substantial economic losses for communities and countries. It also contains information on the global, regional and country-lev...el burden of hypertension and progress of control efforts.

This guidance document is meant to support practitioners working in disaster prone contexts to develop and implement more effective integrated resilience programming. It promotes programming that cuts across different fields of work like rights awareness, food security, emergency preparedness, livel...ihoods, education, health etc. whilst at the same time encouraging us to work simultaneously at the individual, household, community and national level. It includes specific recommendations for developing resilience programming for communities prone to floods, cyclone, drought and earthquakes. It also includes recommendations to develop safe school programming to help reduce the impact of disasters on school infrastructure, ensure education continuity and build the resilience of students, teachers and their families.

The United Nations Network on Migration is committed to supporting all partners in pursuit of the implementation of the Global Compact for Safe, Orderly and Regular Migration, recognizing that this cooperative framework provides an invaluable tool for ensuring inclusive, collective responses to COVI...D-19 and its impact.
To that end, this briefing is part of a series by the Network looking at different aspects of the COVID-19 pandemic and how they relate to migrants and their communities. The document provides practical guidance to States and other stakeholders for an improved common understanding of safe and inclusive access to services for migrants. The brief makes the case for enhanced access to services for migrants in the context of COVID-19 preparedness, prevention, and response – and beyond.

History has shown that governments tend to deprioritize environmental commitments during times of financial and public crises as they work to mitigate immediate needs—and the age of COVID-19 has been no different. Even though human interaction with wildlife is believed to be the cause of the pande...mic, the focus on COVID’s fallout has deprioritized the importance of reversing the damage humans have done to the planet.
COVID has had a multifaceted and detrimental effect on environmental conservation. Not only has funding been diverted to deal with the pandemic, conservation-oriented organizations are operating with minimal staff or have closed entirely. People whose daily work it is to advance environmental science and protect the land and water have become ill or have been forced to stay home because of travel restrictions. Plastic use is at an all-time high.
The good news is that there is an unprecedented opportunity for philanthropy to recharge the effort to protect the planet. This Giving Smarter Guide examines the state of environmental philanthropy, and provides an overview of potential strategic starting points for philanthropy and impact capital to play a role in saving the planet. In addition to offering recommendations specific to the COVID-19 response, the Center for Strategic Philanthropy also asks the questions that philanthropists should consider at the start of their journey into the field of conservation philanthropy.
