A septic tank takes raw sewage in, allows the solids to settle (sludge) and allows the remaining liquid to flow into the surrounding soil by means of a soakaway. Scum on the surface is also prevented from leaving the tank. Microorganisms in the anaerobic environment in the tank digest the sludge and... scum. The system consists of several stages, supply to the tank, the tank itself and the soak field.

Children in Kabwe are especially at risk because they are more likely to ingest lead dust when playing in the soil, their brains and bodies are still developing, and they absorb four to five times as much lead as adults. The consequences for children who are exposed to high levels of lead and are no...t treated include reading and learning barriers or disabilities; behavioral problems; impaired growth; anemia; brain, liver, kidney, nerve, and stomach damage; coma and convulsions; and death. After prolonged exposure, the effects are irreversible. Lead also increases the risk of miscarriage and can be transmitted through both the placenta and breastmilk.

For decades, pollution and its harmful effects on people’s health, the environment, and the planet have been neglected both by Governments and the international development agenda. Yet, pollution is the largest environmental cause of disease and death in the world today, responsible for an estimat...ed 9 million premature deaths.
The Lancet Commission on pollution and health addresses the full health and economic costs of air, water, and soil pollution. Through analyses of existing and emerging data, the Commission reveals pollution’s severe and underreported contribution to the Global Burden of Disease. It uncovers the economic costs of pollution to low-income and middle-income countries. The Commission will inform key decision makers around the world about the burden that pollution places on health and economic development, and about available cost-effective pollution control solutions and strategies.

Human strongyloidiasis is a chronic parasitic disease caused by infection with Strongyloides stercoralis, a soil-transmitted helminth that is estimated to infect 300–600 million people worldwide. This neglected tropical disease (NTD) is endemic globally, predominately in the South-East Asia, Afric...an and Western Pacific regions, and in South and Central America. Strongyloidiasis has a wide range of clinical presentations, including subclinical disease, symptomatic disease (often with diarrhoea, abdominal pain and urticaria) and a rare but deadly complication of hyperinfection with disseminated disease. The feared complication of disseminated strongyloidiasis can occur in the setting of immunocompromising conditions (e.g. human T-cell lymphotropic virus type 1 infection and malignancies) or immunosuppressive medications (e.g. steroids) and has an estimated case-fatality rate exceeding 60%. The standard treatment for chronic S. stercoralis infection is oral medication with ivermectin.

Wash hands with soap and water for 20-30 seconds immediately after taking off PPE. If hands are soiled, wash hands with soap and water for 40-60 seconds. You may use hand sanitizer or chlorinated water, if soap and water are not available.
Water, sanitation and hygiene (WASH) are critical in the prevention and care for all of the 17 neglected tropical diseases (NTDs) scheduled for intensified control or elimination by 2020.
Provision of safe water, sanitation and hygiene is one of the five key interventions within the global NTD ...roadmap. Yet to date, the WASH component of the strategy has received little attention and the potential to link efforts on WASH and NTDs has been largely untapped.
Focused efforts on WASH are urgently needed if the global NTD roadmap targets are to be met. This is especially needed for NTDs where transmission is most closely linked to poor WASH conditions such as soil-transmitted helminthiasis, schistosomiasis, trachoma and lymphatic filariasis.
This strategy aims to mobilise WASH and NTD actors to work together towards the roadmap targets.

Diseases that spread easily have always been around. Sometimes these diseases spread from one person to another person. Sometimes they spread from animals to people. Other times, they spread through germs in the water, soil, food, or air.
Some diseases can be prevented or controlled with a vaccinat...ion, like measles. Other diseases may not have a vaccine or drugs to treat them. Because of this, it is important to prevent the spread of diseases.

Agricultural ecosystems provide humans with food, forage, bioenergy and pharmaceuticals and are essential to human wellbeing. These systems rely on ecosystem services provided by natural ecosystems, including pollination, b...iological pest control, maintenance of soil structure and fertility, nutrient cycling and hydrological services. Preliminary assessments indicate that the value of these ecosystem services to agriculture is enormous and often underappreciated. Agroecosystems also produce a variety of ecosystem services, such as regulation of soil and water quality, carbon sequestration, support for biodiversity and cultural services. Depending on management practices, agriculture can also be the source of numerous disservices, including loss of wildlife habitat, nutrient runoff, sedimentation of waterways, greenhouse gas emissions, and pesticide poisoning of humans and non-target species. The tradeoffs that may occur between provisioning services and other ecosystem services and disservices should be evaluated in terms of spatial scale, temporal scale and reversibility. As more effective methods for valuing ecosystem services become available, the potential for ‘win–win’ scenarios increases. Under all scenarios, appropriate agricultural management practices are critical to realizing the benefits of ecosystem services and reducing disservices from agricultural activities.

A key component of achieving control and elimination of neglected tropical diseases (NTDs) is effective supply chain management of preventive chemotherapy drugs for Mass Drug Administration (MDA) for trachoma, river blindness, lymphatic filariasis, soil-transmitted helminthiasis and schistosomiasis.... This course explains the end-to-end process from planning and submitting donated drug requests through to waste management of expired and unserviceable stock and reverse logistics of unused tablets. It is essential knowledge for all levels of the health system that must work together to implement MDA.

The disease burden caused by poor water, sanitation and hygiene is significant. For instance, soil transmitted helminthes (hookworm, roundworm, ringworm) infest approximately two billion people. Shistosomiasis infects and debilitates 200 million people. Trachoma, a disease related to poor sanitation... and hygiene which can cause blindness, infects five million people. However, the most serious health impact of poor WASH is diarrheal disease, particularly on children.

An IPCC special report on climate change, desertification, land degradation, sustainable land management, food security, and greenhouse gas fluxes in terrestrial ecosystems
As more frequent droughts and floods threaten the global food supply, humans are increasing their demands on water and land,... The New York Times reports.
Data from the Intergovernmental Panel on Climate Change report:
• 500 million people are living in areas that are becoming desert.
• Soil is depleted at 10X-100X the rate it’s being formed.
• More than 10% of the global population is undernourished.
Major threats include the risk of “multi-breadbasket failure”—simultaneous food crises on several continents—and migration triggered by food shortages.
Good News/Bad News: Catastrophe can be avoided, but it would require massive changes to agriculture, food systems and behavior.
A Key Action: Eat less meat. Cattle production is driving deforestation, consuming huge amounts of water, generating methane and causing other impacts, notes Nature.

Over the reporting period, economic actors continued to carry out their activities with little regard for their impacts on the livelihoods of the communities living in the surrounding areas. In Doo Tha Htoo (Thaton) District, cold dust from a Tatmadaw-run cement factory contaminated nearby waterways... during the rainy season. As a result, civilians from at least 15 villages faced water shortages. In Mu Traw (Hpapun) and Kler Lwee Htoo districts, gold mining activities damaged forests and polluted water and soils in several village tracts. In both cases, the economic actors involved failed to secure the free, prior and informed consent (FPIC) of the local population, and did not compensate the affected communities for the damage caused.

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.
