It already is. People aren't eating zoo animals for fun. They are eating them because they are hungry.
Which, in a country as green and lush as Venezuela, makes me wonder if the population is mildly retarded. You probably don't even have to try to grow food there. Just throw seeds on the ground.
Basically most of the farms shut down because the government mandated food prices below the cost of production. Food was imported by the government instead.
Then the government ran out of money, and Venezuela doesn't have food or farms.
If farmers had held out through the hard times Maduro would have just nationalized their farms to try to fix the food problem. So quitting was really their only option.
Anyway, fast forward and nobody is producing food, or at an uncompetitive cost. As noted, the food imports ruined the balance of trade, the falling oil prices ended their exports, and the country went bankrupt.
Has any socialist country survived the death of their cash cow? These experiments seem to work in principle, but only as long as huge amounts of cash are injected from outside.
My point being, there isnt a simple way out. There is no get rid of the president and everything will be fine. It will likely be worse of, even if just for a short while for a lot of people if major NGOs dont step in.
