The human being is the purpose of creation. It was a sign of man's honor and elevated status that he was created last to make known that all mortal creatures were created for his sake and he was made the lord of all of them. And because it is human being must not only care for the world in which they live but bear a special obligation to care about one another. Our duty is to protect one another both physically and spiritually. We are obligated to be concerned about one another's saftey, health, and welfare.
Human beings are responsible for one another.
The chasm separating man from the rest of creation is stressed twice in the statement that he was created in the image of God. Every individual is equally significant before God, since every man was created in His image. This is the opposite of how we usually think of the order of our 24 hour day, which begins with the sun rising and comes to an end with twilight. Yet if you think about it, in the Torah we see many other examples of this reversed order. For instance, the Sabbath begins at night, as do all of our holidays.
