How to deal with this topic in ielts writing

Topic:

Meat production requires relatively more land than crop production. Some people think that as land is becoming scarce, the world's meat consumption should be reduced.

What measures could be taken to reduce the world’s meat consumption? What kinds of problem might such measures cause?

I really confuse how to write this topic. The second question is to answer which problems that people are consuming too much meat production or some problems from measures mentioned in the first question?
