What was the main purpose of this World War II poster?

hope you like it

Explanation:

To preserve resources for the war effort, posters championed carpooling to save on gas, warned against wasting food and urged people to collect scrap metal to recycle into military materials.

Posters were produced asking Americans to try and conserve products such as fats, butter, coffee, and rubber. Conservation was the largest theme among posters produced during the war, as one in seven posters carried this theme. Their efforts were not a waste, as the United States was successful in recycling goods.

according to the quotation from booker t. washington's 1895 atlanta compromise speech.

in the great leap from slavery to freedom . . the masses of us are to live by the production of our hands . . we shall prosper . . as we learn to dignify and glorify common labor.

washington believed that  hard work had its own kind of dignity.
