Bacteria are a major group of micro-organisms that live in soil, water, plants, organic matter, or the bodies of animals or people. They are microscopic and mostly unicellular, with a relatively simple cell structure.
Some bacteria cause diseases such as tetanus, typhoid fever, pneumonia, syphilis, cholera, and tuberculosis.
Bacteria play a role in the decomposition of organic matter and other chemical processes. (Source: GreenFacts)
Biodiversity is a contraction of biological diversity. Biodiversity reflects the number, variety and variability of living organisms.
It includes diversity within species (genetic diversity), between species (species diversity), and between ecosystems (ecosystem diversity). (Source: GreenFacts)
A confounding factor in a study is a variable which is related to one or more of the variables defined in a study. A confounding factor may mask an actual association or falsely demonstrate an apparent association between the study variables where no real association between them exists. If confounding factors are not measured and considered, bias may result in the conclusion of the study. (Source: GreenFacts)
Dental erosion is the loss of enamel and dentine from the tooth as a result of direct acid attack.
It is caused by excessive exposure to acid substances – such as those present in fruit juices and fizzy drinks – that are different from those produced by bacteria involved in the process of dental caries (decay).
Dental erosion is irreversible.
The most common teeth affected by dental erosion are the upper front teeth, although all teeth can be affected. Teeth that have been eroded look glassy, can appear short, and have uneven tips that are easily chipped away.

The benefits people obtain from ecosystems.
These include provisioning services such as food and water; regulating
services such as flood and disease control; cultural services such as spiritual,
recreational, and cultural benefits; and supporting services such as nutrient
cycling that maintain the conditions for life on Earth.

Folate and folic acid are forms of a water-soluble B vitamin that occurs naturally in foods such as leafy green vegetables (like spinach and turnip greens), fruits (like citrus fruits and juices), and dried beans and peas.
They can also be taken as supplements, for instance by women who may become pregnant to prevent certain birth defects. (Source: GreenFacts)
Sufficient folate intake is particularly important in infancy and pregnancy as it helps produce and maintain new cells. Both adults and children need folate to make normal red blood cells and prevent anemia.

The interconnected food chains (feeding relationships) in an ecosystem. Plants, herbivores, and carnivores all form parts of the food web. (Source: GreenFacts)
Any of a group of plant-like microorganisms that include molds, mildews, mushrooms and yeast.
Fungi lack chlorophyll and use living or dead organisms as food by breaking them down and then absorbing the substances into their cells. Many fungi reproduce by disseminating spores which are transported by air and await proper conditions of moisture and temperature to germinate, grow and reproduce. (Source: GreenFacts )

The Joint Group of Experts on the Scientific Aspects of Marine Environmental Protection (GESAMP) is an advisory body, established in 1969, that advises the United Nations (UN) system on the scientific aspects of marine environmental protection.
At present GESAMP is jointly sponsored by nine UN organizations with responsibilities relating to the marine environment, and they utilize GESAMP as a mechanism for coordination and collaboration among them. GESAMP functions are to conduct and support marine environmental assessments, to undertake in-depth studies, analyses, and reviews of specific topics, and to identify emerging issues regarding the state of the marine environment. GESAMP itself today consists of 16 experts, drawn from a wide range of relevant disciplines, who act in an independent and individual capacity. Studies and assessments are usually carried out by dedicated working groups, most of whose members are not sitting members of GESAMP but part of the broader GESAMP network.
GESAMP's UN sponsors: IMO, FAO, UNESCO-IOC, WMO, IAEA, UN, UNEP, UNIDO, UNDP.GESAMP

A virus is a small organism which can infect other biological organisms.
Viruses can only reproduce by invading and taking over cells as they lack the cellular machinery for self reproduction.
They cause diseases in human beings, animals, plants and bacteria.
Examples of human diseases caused by viruses include the common cold, influenza, small pox, AIDS, and cold sores. (Source: GreenFacts)
Vitamins are a group of organic micronutrients that are required by the body for healthy growth, development and immune system functioning.
Certain vitamins are produced by the body but most vitamins are obtained from food or from manufactured dietary supplements. (Source: GreenFacts)
