Trade
Hi,
I read the following passage from an official IELTS exam:
"Bats have a problem: how to find their way around in the dark. They hunt at night, and cannot use light to help them find prey and avoid obstacles. You might say that this is a problem of their own making, one that they could avoid simply by changing their habits and hunting by day. But the daytime economy is already heavily exploited by other creatures such as birds. Given that there is a living to be made at night, and given that alternative daytime trades are thoroughly occupied, natural selection has favoured bats that make a go of the night-hunting trade."
1) What does the phrase "daytime trades" mean here?
2) What does "making" mean in "a problem of their own making"?
Thanks in Advance,
