Answer:
Global warming poses a series of challenges to agriculture, such as:
Changing rain patterns, where there are long periods of heavy rain followed by longer dry periods. That change can occur even within small regions.
The same to temperature patterns, drying up water reservoirs and actually burning up crops that, at that time, need a more humid environment.
Those changes can also trigger greater numbers of floods, droughts, and other effects on crops that livestock depend upon. That change in crops, in turn, may bring new insects that otherwise would not thrive there, decimating entire lands that were naturally protected from, those pests before.
Those are just some of the examples of climate change effects on agriculture and, therefore, to men.
