The equal sharing of Earth’s resources is specifically known as Environmental equity. Environmental equity refers to the fair distribution of environmental benefits and burdens across all populations, ensuring that no group of people, particularly marginalized or disadvantaged communities, suffers disproportionately from environmental harms or lacks access to environmental benefits.

While terms like environmental justice and sustainability are closely related concepts, they cover broader themes. Environmental justice emphasizes the right of all individuals to be treated fairly regarding environmental policies, while sustainability focuses on meeting present needs without compromising future generations. Ecological footprinting, on the other hand, measures the demand on Earth's ecosystems, and mutualism refers to a biological interaction between species where both benefit, which isn't directly related to resource sharing.

In conclusion, among the options provided, environmental equity most accurately defines the equal sharing of Earth's resources.
