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.
The potential variations in the properties of agricul-. tural soils are less well known. Diaz et al. (1994) have. reported that under a climate change scenario the soil. organic matter content and erosion rate would de-. crease with regard to current values in the Arrecifes. River basin.
Climate can affect day-to-day activities, health, agriculture and the environment in which we live. Energy sources can also be affected by changes in the climate. Most people structure their day-to-day activities around the current climate. Climate changes affect society by impacting various social, cultural and natural resources. For example, infrastructure, transportation systems, energy, food, and water supplies are all affected by climate change. The climate also affects economic activities and services.
