Another way to collect a stool sample is to loosely place plastic wrap across the rim of the toilet, under the seat. Then place the stool sample in a clean, sealable container before taking to the laboratory. Plastic wrap can also be used to line the diaper of an infant or toddler who is not yet using the toilet. The stool should be collected into clean, dry plastic jars with screw-cap lids.

In a much-cited 2004 study, he and colleagues found that the percentage of Earthâs land area stricken by serious drought more than doubled from the 1970s to the early 2000s.
