Ecological footprint

The correct answer is option 'C', ecological footprint.

Explanation:

The concept of ecological footprint was introduced in the early 1990s as a measure of the impact of human activities on the Earth's ecosystems. It is a measure of the amount of land and resources required to sustain the lifestyle and consumption patterns of an individual, a population, or a country. The ecological footprint is often used as an indicator of sustainability and environmental impact.

The ecological footprint takes into account the various resources that are needed to support human life, including food, water, energy, and materials. It also considers the waste produced by human activities, such as carbon emissions and pollution. By calculating the ecological footprint, we can estimate how much land and resources are required to support a particular lifestyle or population.

The ecological footprint is measured in terms of global hectares (gha), which represents the average productivity of the Earth's ecosystems. For example, if an individual has an ecological footprint of 2 gha, it means that 2 hectares of land are required to sustain their lifestyle and consumption patterns.

The ecological footprint is a useful tool for understanding the environmental impact of human activities and for making sustainable choices. It can help individuals, communities, and policymakers to identify areas where they can reduce their impact on the environment and live more sustainably.

In conclusion, the minimum area of land required to sustain the life of one person is called their ecological footprint. It is a measure of the resources and land required to support their lifestyle and consumption patterns. By calculating the ecological footprint, we can better understand the environmental impact of human activities and make more sustainable choices.
