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.

Migrant workers and refugees can live in the most disadvantaged urban areas, where access to essential services is already limited. Refugee and migrant children may also be prevented from accessing essential services due to legal, documentation, linguistic or safety barriers. Further, the misinformation on the spread of COVID-19 exacerbates the xenophobia and discrimination that migrant and displaced children and their families already face.

he main symptoms, including severe watery diarrhea, vomiting, and rapid dehydration, which can be fatal without proper treatment. Transmission occurs primarily through unsafe water and poor sanitation conditions. To prevent the disease, it is crucial to have access to clean drinking water, improve hygiene and sanitation, and use vaccination in high-risk areas. In case of infection, oral or intravenous rehydration is the primary treatment, while antibiotics are sometimes administered in severe cases. The video emphasizes the importance of rapid intervention and preventive measures to limit the spread of cholera and protect at-risk populations.

dded the awareness that schistosomiasis is also a disease of poverty. It still survives in poverty-stricken, remote areas where there is little or no safe water or sanitation, and health care is scarce or non-existent. For a variety of complex reasons, many of which are addressed in this book, the disease is particularly prevalent in sub-Saharan Africa, and persists in certain areas of rural China. This concern for human behaviour in an environment of poverty echoes the concerns of the new research priority for “diseases of poverty” identified by the Special Programme for Research & Training in Tropical Diseases.

are already exposed to frequent heatwaves in a region where temperatures are rising at the fastest rate globally. The increasingly high temperatures can have serious health complications for children, especially the youngest children, even in a short space of time. Without care, these complications can be life-threatening,” said Regina De Dominicis UNICEF Regional Director for Europe and Central Asia.
Heat exposure has acute effects on children, even before they are born, and can result in pre-term births, low birth weight, stillbirth, and congenital anomalies. Heat stress is a direct cause of infant mortality, can affect infant growth and cause a range of paediatric diseases. The report also notes that extreme heat caused the loss of more than 32,000 years of healthy life among children and teenagers in the region.
As the temperatures continue to rise, UNICEF urges governments across Europe and Central Asia to:
- Integrate strategies to reduce the impact of heatwaves including through National Determined Contributions (NDC), National Adaptation Plans (NAP), and disaster risk reduction and disaster management policies with children at the centre of these plans
Invest in heat health action plans and primary health care to more adequately support heat-related illness among children
- Invest in early warning systems, including heat alert systems
- Adapt education facilities to reduce the temperatures in the areas children play in and equip teachers with skills to respond to heat stress
- Adapt urban design and infrastructure including ensuring buildings, particularly those housing the most vulnerable communities are equipped to minimize heat exposure
- Secure the provision of safe water, particularly in countries with deteriorating water quality and availability.
UNICEF works with governments, partners and communities across the region to build resilience against heatwaves. This includes equipping teachers, community health workers and families with the skills and knowledge to respond to heat stress.
