To determine three environmental health hazards that cause ill health, crises, and disasters in South Africa and globally, you would typically start by researching current issues and examining available evidence. Here is a step-by-step guide on how to find this information and identify the hazards:
1. Conduct General Research:
- Start by conducting a broad online search using keywords related to environmental health hazards in South Africa and worldwide.
- Look for reputable sources such as government websites, international organizations like the World Health Organization (WHO), and research institutes or universities.
2. Gather Information about South Africa:
- Focus on South Africa's specific environmental health concerns. Look for recent reports, articles, or studies that provide insights into the hazards affecting the country.
- For example, explore topics like air pollution, water contamination, waste management, industrial activities, or climate change effects.
3. Consider Global Environmental Health Hazards:
- Expand your research to include global environmental health hazards. Look for evidence that indicates the hazards' impact on health, crises, or disasters on a global scale.
- Potential topics to investigate could include climate change, deforestation, natural disasters, toxic waste, air pollution, or water scarcity.
4. Evaluate the Evidence:
- When examining the identified issues, prioritize recent evidence (within the last five years) to ensure accuracy and relevance.
- Look for studies, reports, or statistics that provide clear evidence of the hazards' effects on communities' health, crises, or disasters.
Based on the research done using the above methodology, I will provide an example of three environmental health hazards affecting South Africa and/or global communities, along with current evidence supporting their impact:
1. Air Pollution:
- This hazard is prevalent in many communities, especially in urban areas where industrial activities, transportation, and coal burning contribute to high levels of pollutants in the air.
- Evidence: According to an article published by WHO in 2020, air pollution is responsible for approximately 7 million premature deaths globally each year, with outdoor and household air pollution being major contributors.
2. Water Contamination:
- In many regions, inadequate sanitation, industrial discharge, and agricultural runoff can lead to water contamination, causing serious health issues such as diarrhea, cholera, and other waterborne diseases.
- Evidence: A study conducted by South Africa's Department of Water Affairs revealed high levels of bacterial contamination in rivers due to inadequate waste management practices and pollution from various sources.
3. Climate Change Effects:
- Global climate change leads to severe consequences such as increased frequency and intensity of extreme weather events, rising sea levels, and altered ecosystems, all of which pose significant health risks.
- Evidence: The Intergovernmental Panel on Climate Change (IPCC) reports that climate change impacts are already affecting human health worldwide, leading to increased mortality, malnutrition, and the spread of vector-borne diseases.
