By the middle of the 21st century, if present【B2】______ continue, we will have used up all the oil that drives our cars, for example.

In a fairly short time, the algae will【B8】______ the carbon dioxide into oxygen and carbon.
When the algae have done their work, the atmosphere will become cooler but before man can set foot on Venus, it will be necessary for the oxygen to produce rain.
