In this era, grand challenges lies in biodiversity loss, climate change, and global noncommunicable diseases signify that planet and humanity are in crisis. Scholarly evidence from human and animal kingdom suggest that there is an optimism in planetary health which can provide a unique and novel concept where efforts toward survival and remediation can be made. With accurate navigation, the current challenges can be mitigated leading to a new reality, one in which the core value is the well-being of all. This paper discusses the drivers of planetary health and the role of community health workers (CHWs) in making health-care system more resilient that can produce multiple benefits to community and overall planetary health. A web-based international database such as Google, Google Scholar, SCOPUS/MEDLINE/PubMed, and JSTOR was searched relevant to a planetary health framework. The study findings suggest that CHWs can offer health care interventions through environmental health cobenefits across the spectrum of health effects of climate change cause and effects. These actions have been divided into four major categories (i. health care promotion and prevention, ii. health care strengthening, iii. advocacy, and iv. education and research) that CHWs perform through a variety of roles and functions they are engaged in protecting planetary health. CHWs contribute toward achieving sustainable development goals such as planetary health and focus on environment sustainability and well-being of entire mankind.

| Introduction|| |
We are seeing a rapidly changing world in and around us. Multiple environmental changes such as huge scale biodiversity damage, environmental deviation, deforestation, land degradation, and ocean acidification have substantial effects but their implications on population health is still not fully understood. The prospective of future global health is under threat with new emerging infectious disease and mounting noncommunicable disease burden that contributes much to the global burden of disease, displacement, growing nutritional vulnerability, mental health risks, and susceptibility to injury and accident, all of which disproportionately intimidate mankind mainly the elderly, the young, the poor, and the future generation. The focus of planetary health characterizes the connections between human-caused disruptions of Earth's natural systems and the resulting impacts on human health and makes the case for globally concerted action. Three recent reports emphasize the concerted efforts needed to preserve and protect planetary health.
First, the Intergovernmental Panel on Climate Change reported that the world could be warmer by 1.5°C as early as 2040. Rapid and significant transitions should be carried out with respect to land, energy, buildings, industries, and transport system and in cities to limit global warming by 1.5°C. Any continuity of carbon dioxide (CO2) emission needs to be balanced to reduce global warming by expelling excess amount of CO2 from the air. On the global context, net human-caused emission of CO2 need to fall by 45% from 2010 levels by 2030 and reach “net zero” around 2050.
Second, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) has reported a harsh news for the future of mankind that the biosphere has been tampered to a large extent that it is highly affected and is declining very rapidly. The largest impacts are due to direct exploitation of organisms, pollution, climate changes, and invasive alien species, but mostly due to the alteration of flora and fauna. To tackle these crises, five interventions are recommended: capacity building and incentives, strengthening cross sectoral cooperation, pre-emptive actions, decision making in case of resilience and uncertainty; and formulation of environmental law and implementation.
Lastly, the UK's Committee on Climate Change (CCC) focuses primarily on preparing for climate change. In addition, it provides independent advice to government on building a low carbon economy. It has also recommended a new target for the UK, i.e., to bring down greenhouse gases to level zero (net zero) by 2050 and to deliver on the commitment that the UK has signed in the Paris Agreement which states to bring improvements in people lives which could be achievable with known technologies. Nevertheless, it also states that this is possible only when there are clear, stable, and well-designed policies aiming to reduce emissions and it must be introduced across the economy without delay. The current policies are not sufficient to achieve the existing targets; hence, it must be revised.
| Role of Community Health Workers (CHWs)|| |
Community health workers (CHWs) are frontline functionaries to deliver patient-centric, comprehensive primary health care, address social determinants of health, and respond to various health challenges and outcomes. CHWs not only promote preventive health measures to the population they serve but also enhance community resilience. A number of environmental hazards such as climate change, ocean acidification, extreme weather, ecosystem collapse, sea level rise, fresh water depletion, reduced agricultural productivity, biodiversity loss, air pollution, and toxic chemical exposure jeopardize the human health advancement that has been experienced in the last few decades. The role of CHWs, therefore, can be instrumental in creating awareness to address some of these environmental variations. For instance, in climate change, actions and leadership of CHWs can boost the existing efforts to mitigate climate challenge, therefore, producing multiple benefits to community, health-care system, and overall planetary health.
The health effects of extreme weather change can be classified as direct (such as flood or drought), indirect (such as ecosystem change after experiencing flood or drought leading to distribution of disease vectors), or through social mediating processes (such as mass migration after violent conflict or drought)., These three pillars interact with one another, amplifing climate risk, which are primarily driven by global development and demographic transitions. The other social determinants of health also affect population vulnerability to climate change and their impacts are unevenly distributed, with greater burden of risk in less-developed economics. The policies and provisions that address the reduction of social determinants empower various actors to support longer-term development and the drivers of climate change can encompass all sectors, including, energy, agriculture, health, transportation, and economy. The mitigation and adaption action of climate change could lead to direct reduction in burden of disease, alleviate poverty, increase community resilience, and address global inequity.
CHWs have the potential to enhance primary health care and are particularly effective when they share common culture, ethnicity, economic status, language, and life experiences with communities they serve. A growing body of evidence highlights that the diverse roles CHWs carry out in community and global settings can be utilized for primary care., They can influence policy makers for favorable provisions to reduce environmental impact of health care and, thereby, provide health cobenefits. The evidence illustrated that CHWs are widely connected to the community and act as more trusted persons than government functionaries and other public health professionals., They can act as a key leader in the community and advocate for evidence-based interventions for policy outreach and implication. They can offer health care interventions through environmental health cobenefits across the spectrum of health effects of climate change cause and effects [Figure 1]. These actions have been divided into four major categories that CHWs perform through a variety of roles and functions.

| Health Care, Promotion, and Prevention|| |
First, CHWs have a major role in providing health care, promotion and prevention apart from treating the patients. They can give advice to people for behavioral change that have environmental cobenefits. For example, CHWs could encourage for active transport through physical activity rather than motorized transport, take healthiest diets that have less environmental impact such as no to red meat, high intake of fruits, green leafs, and vegetables that are healthy for the planet and the individual. CHWs also adjust medications to adapt environmental stress who have already existing diseases. For example, proper guidance and follow-up along with modification of dosage, drug course, and self-medication is required for geriatric persons at the time of heat waves. In addition, CHWs are the first contact point of community for any illness and serve as important front-line health workers for the implementation of community health program and execute surveillance function for various infectious and noninfectious diseases, as seen in other countries such as in Brazil and India. More so, CHWs play a major role in the aftermath of climate-related events (e.g., disasters such as storms and floods) to provide necessary support in disaster risk reduction strategies especially to reduce mental and physical health effects of afflicted people.
| Health System Strengthening|| |
Second, CHWs also play a very crucial role in health system strengthening. CHWs represent a robust proportion of human resources for health worldwide; so, they can give recommendation on workforce planning on the anticipated degradation of environmental conditions, such as zoonotic diseases that arise from animals and land use, respiratory diseases, and other climate changes. Their active involvement to the communities help in addressing environmental and social determinants of health rather than looking at the fully biomedical research to care for vulnerable populations, such as older people and young children, people with disability, poor and marginalized communities, and disaster-prone populations. In addition, health effects of climate change can be mitigated by the improvement of the primary-health care infrastructure; for instance, by decreasing the emissions of climate-altering pollutants (CAPs) through improved low carbon energy sources or energy efficiency.,
| Advocacy|| |
Third, CHWs have an important part in advocacy for planetary health activities. They can take part in social marketing on climate change and advocate for mitigation and adaption actions to protect the planet. CHWs can alert policy makers to take actions that affect climate change by addressing the health benefits. For example, they may advocate the negative health outcomes due to increased fossil fuels and use of well-designed carbon taxes to reduce income inequality and improve overall quality life. The various professional bodies such as World Federation of Public Health Association and World Organization of Family Doctors should take leadership roles in this process. At the door step and local level, CHWs could lead community health initiatives and movements, join in community organizations, and act as role models, for instance, by leading active walk campaign, waste recycling, and low-carbon healthy lifestyles.
| Education and Research|| |
Fourth, CHWs are pivotal to introduce the concepts of planetary health research and education using education materials and training curriculum related to planetary health., CHWs directly impart training to community on public health education and the planetary health material can be developed with inputs from the primary health care units. The policy makers also seek support from the expert opinions of CHWs on planetary health approach for policy outreach and informed decisions. This can be done through collaborative workshops, conferences, and deliberations with CHWs. In teaching and research, CHWs can recommend priority areas of planetary health research for population health, such as recent examples of the phasing out of coal to replace it with cleaner energy and air quality alert evaluation, yielding positive gains for society. The climate change and other environmental variations may also have an impact on individual clinical manifestation or to population health changes (such as changes in health due to extended allergy periods or death of elderly population due to heat wave).
| Relevance of Planetary Health to the Practice of Primary Care|| |
Primary care plays a very crucial role in improving population health, and planetary health., Primary care providers including CHWs worldwide counsel millions of patients every day and enjoy society's trust and recognition. These attributes offer them great personal and political attention not only in providing healing touch to patients' health but also improving the health of the planet. In the promotion of healthy lifestyles, primary care must consider that global warming is human- induced, with live-stock contributing a tremendous share of the global greenhouse emissions. Evidence suggest that livestock alone contribute to around 80% of the agricultural emissions, out of which animal products contribute to around 20% of the global greenhouse emissions leading to massive destructions of biodiversity. Therefore, primary care teams including CHW can become role models and act as educators in their community for healthy lifestyles and to promote healthy public policies to protect public health and planetary health. Primary care can spread meaningful messages in various ways to their communities. For instance, the WONCA Air Health Train the Trainer programme in low- and middle-income countries, trains family doctors and medical workers that influence communities to improve air quality. As a result, the reduction of greenhouse gases has been envisioned. In Borneo, a project named Health in Harmony that has stopped deforestation, transformed the landscape and increased human wellbeing.
It has been evident that ecosystems across the globe are threatened by massive biodiversity loss and climate change.,,,, We need to initiate a holistic approach to protect the health of the planet and place “wellbeing of all” as the fundamental aspect at the heart of decision making. Therefore, the cooperation of various governments, enforcement of existing laws, and formulation of new laws with all precautionary measures and incentives would be crucial to protect the planet. An urgent need requires for all key stakeholders (national and state governments, industries and corporates, institutions, communities, and individuals) to recognize the importance of planetary health. They should carry out their own planetary health impact assessment study and could inform feasible interventions to protect or at least minimize the harm to environment, health and biodiversity loss. At the same time, pragmatic decisions should be made on how we can make meaningful contribution toward the restoration and reparations of natural systems. By doing so, we can not only bring health cobenefits to mankind but also defeat some of the world's major public health challenges by improving nutritional security, improving air quality, and increasing physical activity which can reduce the huge cost and harm that arise while nurturing our present sick planet.,,, In moving forward, active outreach on planetary health must be intensified by the policy makers and general public to advocate the pressing issues faced at the health and environmental level and to participate in the promotion of global health and planetary health.
| Conclusion|| |
The association between human health and natural systems are complex and primary care is vital for restoring global commons which include land, water, minerals, and vegetation of the planet. This paper provides unique linkage between planetary health and primary care discussing the usefulness of more efficient engagement of CHWs, given their influential role in primary care, for improvement in planetary health. Our framework emphasizes the perfect equivalents between changes in health behaviors (e.g., nutrition, exercise, and smoking) and climate change mitigation and adaption actions. CHWs can serve as a strong mediator of these actions that can promote environmental change. The multifaceted and complex nature of climate change on health effects require the unique skill of CHWs that has to be embedded to their legitimacy to act as knowledge experts by upholding close professional liaison with the community they serve. We are confident that the policy makers and public health planners would recognize the critical role of CHWs and tailor-make the primary care policies for active participation of CHWs in protecting planetary health. The success of the future generation lies in caring and upholding the planet in good health.
