Property rights aim to define and enforce the rights and responsibilities of individuals or groups in relation to the use and management of environmental resources.

Open access refers to the absence of clearly defined property rights, resulting in the overuse and degradation of environmental resources.

The Coase theorem posits that if property rights are well-defined and transaction costs are low, private parties can negotiate and reach efficient solutions to environmental externalities without government intervention.

Common property resources are collectively owned and managed by a community or group, with defined rules and regulations for their use and conservation.

The 'tragedy of the commons' refers to the situation where individual incentives to overuse a common resource lead to its depletion or degradation, even if it is collectively beneficial to conserve it.

Pollution taxes impose a fee on polluters based on the amount of pollution they generate, incentivizing them to reduce their emissions and adopt cleaner technologies.

The 'environmental Kuznets curve' posits that as economies grow, environmental degradation initially worsens due to industrialization and resource exploitation, but eventually improves as economies transition to cleaner technologies and sustainable practices.

Non-point source pollution originates from diffuse sources, such as agricultural fields, construction sites, or urban stormwater runoff, making it difficult to identify and control.

The Montreal Protocol is a global agreement to protect the ozone layer by phasing out the production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).

Sustainable development aims to balance economic growth, social progress, and environmental protection, ensuring that the needs of the present generation are met without compromising the ability of future generations to meet their own needs.

The 'polluter pays' principle assigns the responsibility for environmental damage to the polluter, incentivizing them to reduce pollution and adopt cleaner technologies.

Renewable energy sources are those that can be replenished naturally on a human timescale, such as solar energy, wind energy, and hydropower.

The 'precautionary principle' advocates for taking proactive measures to prevent environmental harm, even if the scientific evidence is not conclusive, in order to minimize potential risks.

Biodiversity hotspots are regions with exceptionally high levels of biodiversity and endemism, and are considered priorities for conservation efforts.

The 'ecological footprint' is a measure of the amount of land and resources required to produce the goods and services consumed by a population, including the land used for agriculture, forestry, and urban development.
