Answer to Question 1

The SDGs are more numerous and complex than the MDGs; there were 8 MDGs, but there are 17 SDGs, each with numerous targets. The SDGs also have more parts focused on environmental sustainability. Like the MDGs, the SDGs may be very difficult to achieve. While the MDGs aimed to cut poverty in half by 2015, the SDGs aim to eradicate extreme poverty by 2030.

Answer to Question 2

The Montreal Protocol, signed by 194 countries, has been a significant stride forward in the protection of ozone. CFCs have been reduced to the point that they are barely produced at all anymore. The results of the protocol can be seen clearly in Figure 19-31, which shows the time course of the production of ozone-depleting chemicals and the abundance of those chemicals in the stratosphere.
