Planetary health encompasses the health of human populations and ecosystems, as well as the stability of the Earth's climate system. Economic growth, while important for human well-being, is not a direct component of planetary health.

Environmental degradation, environmental pollution, and climate change are all terms used to describe the negative impact of human activities on the environment.

Deforestation, fossil fuel combustion, and overpopulation are all major causes of environmental degradation. Renewable energy production, on the other hand, is a sustainable alternative to fossil fuels and does not contribute to environmental degradation.

One Health is a term used to describe the interconnectedness of human health, animal health, and the environment. It recognizes that these three elements are inextricably linked and that the health of one cannot be achieved without the health of the others.

Environmental degradation can lead to increased risk of respiratory diseases, cardiovascular diseases, and cancer. It does not, however, lead to improved mental health.

Resilience is the ability of an ecosystem to maintain its structure and function in the face of disturbances. It is a key factor in determining the health of an ecosystem.

Reducing greenhouse gas emissions, protecting biodiversity, and promoting sustainable agriculture are all key factors in achieving planetary health. Increasing economic inequality, on the other hand, is not a key factor and can actually hinder the achievement of planetary health.

Environmental sustainability is the process of reducing the negative impact of human activities on the environment. It involves adopting practices that minimize resource depletion, pollution, and other forms of environmental degradation.

Climate change, biodiversity loss, and pollution are all key challenges in achieving planetary health. Overconsumption, while a significant issue, is not a key challenge in the same way as the other options.

Climate-related health impacts, climate-related diseases, and climate-related mortality are all terms used to describe the impact of climate change on human health.

Clean air and water, healthy ecosystems, and sustainable food systems are all key components of a healthy planet. Economic growth, while important for human well-being, is not a direct component of a healthy planet.

Ecological restoration is the process of restoring damaged ecosystems to their natural state. It involves a variety of techniques to restore the structure, function, and biodiversity of an ecosystem.

Education and awareness, policy and regulation, and technological innovation are all key factors in promoting planetary health. Individual behavior change, while important, is not a key factor in the same way as the other options.

Carbon mitigation, climate mitigation, and greenhouse gas reduction are all terms used to describe the process of reducing greenhouse gas emissions to mitigate climate change.

Minimizing food waste, promoting local and organic food production, and reducing the use of pesticides and fertilizers are all key components of a sustainable food system. Increasing meat consumption, on the other hand, is not a key component and can actually have negative environmental impacts.
