Suppose you have two people, one of whom likes only bananas and the other only pears. If both people have one apple and one pear each then the situation is not Pareto efficient. If the pear-lover were to give his apple to the apple-lover in return for the apple-lover’s pear, then the situation would become Pareto efficient, as now that the pear-lover has both pears and the apple-lover both apples, any further change in the distribution would be worse for either or both of them.
