The Principle of Sustainability aims to balance the needs of the present with those of the future, ensuring that resources are used in a way that does not compromise the ability of future generations to meet their own needs.

While economic growth can be a component of sustainability, it is not a central aspect of the Principle of Sustainability. The focus is on ensuring the well-being of future generations and preserving the environment, rather than solely pursuing economic expansion.

(\text{Carrying capacity}) is a crucial concept in sustainability, as it defines the limits of resource use and population growth that an environment can sustain without compromising its integrity.

Sustainable practices encompass a wide range of actions that aim to minimize negative impacts on the environment and ensure the well-being of future generations. These practices include using renewable energy, preserving biodiversity, and reducing waste and pollution.

The (\text{full costs}) of resource use encompass not only the direct financial costs but also the indirect environmental and social costs, such as pollution, habitat loss, and social inequality.

Implementing the Principle of Sustainability faces several challenges, including the lack of scientific knowledge, the difficulty in balancing present and future needs, and the resistance from industries that benefit from unsustainable practices.

(\text{Sustainable development}) aims to balance economic growth, social equity, and environmental protection, ensuring that the needs of the present are met without compromising the well-being of future generations.

The (\text{triple bottom line}) approach to sustainability evaluates the financial, environmental, and social impacts of a project, aiming for a balance between these three dimensions.

(\text{Intergenerational equity}) is the ethical principle that emphasizes the responsibility of present generations to ensure that the actions they take do not compromise the well-being of future generations.

Policies that promote (\text{intergenerational equity}) aim to ensure the well-being of future generations by investing in sustainable practices, protecting the environment, and reducing the negative impacts of climate change.

(\text{Environmental ethics}) encompasses the study of the relationship between humans and the environment, the development of ethical principles for guiding human interactions with the environment, and the analysis of the moral implications of environmental policies and practices.

Biocentrism is an ethical theory that emphasizes the intrinsic value of all living beings and the natural world, regardless of their usefulness to humans.

(\text{Ecological footprint}) is a measure of the amount of land required to support a population's consumption, taking into account the resources used, the waste generated, and the impact on biodiversity.

A (\text{circular economy}) approach to sustainability aims to minimize waste and pollution by designing products for reuse and recycling, using renewable energy sources, and reducing consumption.

The (\text{precautionary principle}) is an ethical principle that emphasizes the importance of taking action to prevent harm, even if the scientific evidence is incomplete, in order to protect human health and the environment.
