A common example of a nonelectrolyte is glucose, or C6H12O6. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
The laws have made it harder for criminals to harvest the ivory, therefore less harvesting occurs. So you could say it affected the population positively, letting the population increase.
