Question

Accepted Answer

The correct option is 1:

Detailed explanation of why it is correct — include conceptual, or contextual depth.

The correct option is **1: James Lovelock**. The GAIA hypothesis was formulated in the 1960s by the British independent scientist and environmentalist, James Lovelock, and later co-developed with the American microbiologist Lynn Margulis. The hypothesis proposes that all living organisms on Earth, and their inorganic surroundings, are closely integrated to form a single and complex interacting system, a self-regulating super-organism. This planetary system, which Lovelock named after the Greek Goddess of the Earth, Gaia, is capable of maintaining the chemical and physical conditions of the planet's surface environment so as to be optimum for life. Lovelock's work suggests that life not only adapts to the environment but actively shapes and regulates it, maintaining homeostasis (a stable internal equilibrium) on a planetary scale. This concept profoundly shifted environmental thinking, moving beyond the idea of life simply being passive inhabitants of the Earth to being active controllers of global systems.

**Carolyn Merchant** is an American philosopher and historian, known primarily for her work in environmental history, philosophy, and ecofeminism. Her major contribution lies in challenging the mechanistic worldview that emerged during the Scientific Revolution, arguing that it led to the domination of nature. Her seminal work, *The Death of Nature: Women, Ecology, and the Scientific Revolution*, connects the control of nature with the subjugation of women, promoting a critical perspective on environmental ethics. While deeply involved in environmental thought and theory, her focus is on historical changes in human perception of nature and the feminist critique of environmental destruction, not the geological and biological feedback loops proposed by the GAIA hypothesis.

**Vandana Shiva** is an Indian philosopher, environmental activist, and anti-globalization author. Her work is primarily centered on biodiversity, agriculture, and promoting sustainable farming practices. Shiva is a leading figure in the global movement against corporate control over seeds and resources, advocating for seed freedom and organic farming. She developed the concept of 'Earth Democracy' and has been highly critical of the Green Revolution and genetic engineering. Although her work is foundational to modern environmentalism and ecological justice, it deals with socio-economic and political critiques of environmental degradation in the Global South, distinguishing her from the biogeochemical system theory of the GAIA hypothesis.

**Garrett Hardin** was an American ecologist and microbiologist best known for his influential 1968 essay, "The Tragedy of the Commons." This work addresses the conflict between individual and collective interests regarding shared resources. Hardin argued that when individuals act independently and rationally, according to their self-interest, they ultimately deplete a shared resource, even when it is not in anyone's long-term interest. His work focuses on population control, resource management, and ethical responsibilities regarding shared natural assets. Hardin’s contributions are significant in the field of resource economics and policy theory, but they are focused on human behavior and management problems rather than a self-regulating planetary system, making him unrelated to the formulation of the GAIA hypothesis.
