Summary
Forests offer significant physical and mental health benefits, acting as natural pharmacies and food sources. However, ecosystem degradation and lack of policy implementation hinder realizing their full health potential.
Area of Science:
- Environmental science
- Public health
- Ecology
Background:
- Forests provide crucial ecosystem services impacting human well-being.
- The relationship between forests and human health is complex, encompassing benefits and risks.
- Global change and biodiversity loss pose threats to these forest-human health connections.
Purpose of the Study:
- To review the health benefits and risks associated with forests.
- To identify challenges in forest-human health research and practice.
- To explore the potential of forests in health promotion and disease regulation.
Main Methods:
- Literature review synthesizing existing research on forests and human health.
- Analysis of forest benefits including physical/mental health, medicinal resources, and food security.
- Examination of risks posed by forests and challenges to implementation.
Main Results:
- Forest visits demonstrably improve physical and mental health by reducing stress.
- Forests are vital sources of medicinal compounds and nutritional resources.
- Healthy forest ecosystems contribute to regulating infectious diseases and supporting vulnerable populations.
Conclusions:
- Forests offer substantial opportunities for improving human health and reducing healthcare costs.
- Ecosystem degradation, deforestation, and climate change present major challenges.
- Translating research into practice requires enhanced evidence, policy-maker awareness, and inter-sectoral collaboration.

01:24Biodiversity and Human Values
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.
01:50Threats to Biodiversity
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
01:21Dimensions of Health and Illness
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.
01:30Primary Healthcare Services
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.

01:26Methods Of Healthcare Delivery System
At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is limited...

01:43Sustainable Development
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.
