Part 3 One Health: Environment Health Flashcards
Neglected component of the One Health triad
Environment
Importance of Environmental Health
Many of the same microbes infect animals and humans as they share the ecosystems where they live in
Investigates stressors on the environment and the role they play in diseases transferred by animals to humans
Environmental Health Perspective
Main Problem of Environmental Health
The environment is subject to variable weather patterns and
climate change compromises the ecological and environmental integrity of living systems
Environmental Stressor:
-Agricultural expansion
-Urbanization
-Destruction of habitat of local wildlife
Land use change
Has its greatest impact on people whose health status is already at risk; Lack of safe and livable space; Poor air and water quality contributes to diseases
Poor Environmental Quality
Natural communities of organisms; Physical environment with which they interact and their functioning as an ecological unit
Ecosystems
Complex mixture of physical, chemical and biotic factors including land, air, water, soil and all living things that interact within it
Environment
Environmental Stressor:
-Air pollution
-Water, ocean pollution
Toxicity and Chemical Pollution
Four (4) Environmental Stressors
- Land use change
- Biodiversity Decline
- Climate Change
- Toxicity and Chemical Pollution
Environmental Stressor:
-Overconsumption of wildlife
-Wildlife tradeIntroduction of invasive species
Biodiversity Decline
Process by which large numbers of people become permanently concentrated in relatively small areas forming cities
Urbanization
Several Key Issues Identified as Major Obstacles in Economic Growth
-Poor business environment
-Weak infrastructure, land management and access to markets
-Low demand for innovation and skill match
-Limited access to finance and business support
-Insufficient economic planning
Examples of Resource Mismanagement
-Water crisis for domestic and agricultural sectors
-Energy poverty as real energy crisis
-Land governance crisis leads to congestion in cities and urban nightmare
Complex shifts now affecting the planet’s weather and climate systems
Climate Change
