1. What are greenhouse gases and how do they contribute to global warming?

Greenhouse gases are gases that trap heat in the atmosphere. There are four greenhouse gases. Greenhouse gases (GHGs) warm the Earth by absorbing energy and slowing the rate at which the energy escapes to space; they act like a blanket insulating the Earth. Different GHGs can have different effects on the Earth’s warming. Two keyways in which these gases differ from each other are their ability to absorb energy (their “radiative efficiency”), and how long they stay in the atmosphere (also known as their “lifetime”) (1, United States Environmental Protection Agency (EPA).

· Carbon Dioxide (CO2).

· Methane (CH4)

· Nitrous Oxide (N2O)

· Fluorinated Gases

2. What kinds of economic challenges do these emissions pose to the people of the developing world?

3. What is food insecurity (as opposed to hunger) and what is the relationship between it and population growth?

4. What role do developing world governments play in aggravating food insecurity?

5. What factors specifically interrupt the flow of food from its sources to populations in the developing world?
