Question
An increase in carbon dioxide content in the atmosphere would not cause

global warming
the abundance of desert plants

Solution
the abundance of desert plants
Explanation:
Since carbon dioxide is a greenhouse gas, an increase in its concentration will lead to the retention of more heat by the environment. The increased level of carbon dioxide and temperature will increase the rate of photosynthesis in plants. The retention of heat due to increased CO2 concentration will cause an increase in average global temperature, resulting in global farming. Since the increase in CO2 concentration does not create xerophytic conditions, thus there is no increase in the abundance of desert plants.

We often leave the lights switched on and fans running when we are not in the room. We switch on the air-conditioning even though we don’t really need it.
