- Xenobiotics: chemicals that provide important clues about the way a
substance foreign to an organism interferes with the body’s natural
signaling pathways

- A chemical is a substance produced by or used in a chemical process
- Refer to our IDS website and look at Chapter 2 of Cunningham and
Cunningham for the different chemical processes that have been listed on
those slides
- For example: the water we drink; the air we breathe; the foods we eat
and so are a result of a chemical process

- Hormones are the chemical messengers of our body
- Hormones are secreted by the endocrine system and used at the cellar
level for communication between body tissue including the brain, organs,
other glands, muscles and other tissues of the body

- The word “geo” or “ge” is defined
as “earth”, thus, the word “geography” is the study of the earth and its
features and of the distribution of life on the earth, including human
life and the effects of human activity.
- “geology” is the scientific study of the origin, history, and structure
of the earth. It is also, the structure of a specific region of the
earth’s surface; and also, the scientific study of the origin, history
and structure of the solid matter of a celestial body.
- What is the point of this clarification?

- You are expected to know the geography of the country you have chosen
for your group work as well as the geography of the region where the
country is located.
- The geology of the country/region will indicate what chemical processes
have occurred or are occurring presently, such that it impacts on the
environment of the nation and the people.

|
- Human diseases are traced to the chemical processes by location, diet,
activities and other related information as proved by scientific
research data.
- Again, I will ask you to refer to the IDS website for the geography of
diseases (Chapter 8 of Cunningham and Cunningham).

- Figure 8-1 listed the leading causes of death globally from
Cardiovascular disease to Cancers, Lung diseases etc.
- Review all the slides and use the information in your group activities
discussing environmental and economic activities vis-à-vis sustainable
development.
