Conservation aims to safeguard and maintain the integrity of natural resources, ecosystems, and biodiversity for the benefit of both present and future generations.

Conservation prioritizes the preservation and restoration of natural resources and ecosystems, rather than solely focusing on economic growth, which can often lead to environmental degradation.

Extinction refers to the irreversible loss of a species from the Earth, often as a result of human activities and environmental changes.

Deforestation, the clearing of forests for various purposes such as agriculture, logging, and development, is a significant cause of habitat destruction and loss of biodiversity.

Rewilding involves restoring degraded ecosystems to their natural state, often by reintroducing native species and allowing natural processes to take place.

Renewable resources are those that can be replenished naturally, such as solar energy, wind energy, and hydropower.

Sustainable development aims to meet the needs of the present without compromising the ability of future generations to meet their own needs.

Biodiversity contributes to ecosystem stability and resilience, providing numerous benefits such as clean air and water, pollination, and protection from natural disasters.

Decarbonization involves reducing or eliminating the use of fossil fuels, which release carbon dioxide and other greenhouse gases into the atmosphere.

Greenhouse gases are gases that trap heat in the atmosphere, contributing to global warming. Oxygen is not a greenhouse gas.

Preservation involves maintaining natural areas in their original condition, often through legal protection and management.

All of the listed options are types of pollution.

Reducing involves minimizing the amount of waste generated in the first place, often through conscious consumption and lifestyle choices.

Nuclear energy is not considered a renewable energy source because it involves the use of non-renewable uranium.

Reforestation involves planting trees in areas where forests have been cleared or degraded.
