DIscussion 1:One Breath at a TimeThis week you watched three videos, each describing a type of pollution. Choose one of these three pollution types and explain two ways an individual person can make meaningful changes to prevent or alleviate it.
Discussion 2:Getting Thirsty
Water covers 75% of the earths surface. Most of it contains high concentrations of salt and is unusable to developing countries for consumption or irrigation purposes because desalination is too expensive. Consequently, when a water source like a major river originates in one country and flows into another, the shared water source could become an issue of national security. (This means that if one country dams or diverts a shared river for irrigation purposes, it could reduce the amount of water flowing downstream to the second country). For example, nearly all of the major river systems that flow through Pakistan originate in India or, in the case of the Indus River, in Tibet meaning that India essentially controls Pakistans ability to grow food for itself.For this week’s discussion, think of the enduring disputes taking place between Jordan and Israel (Jordan controls the headwaters of the Jordan River as it flows into Israel); Turkey and Iraq (Turkey controls the Tigris and Euphrates Rivers before they enter Iraq); and between Ethiopia and Sudan and Egypt (Ethiopia controls the flow of the Nile River before it enters Sudan and Egypt). What concerns do these downriver countries (Israel, Iraq, and Egypt/Sudan) have over freshwater access?
