To identify and describe three environmental health hazards that cause ill health, crises, and globally, we can look at air pollution, water pollution, and climate change. Here's how you can find evidence using graphs, statistics, pictures, and other sources:
1. Air Pollution:
Air pollution refers to the presence of harmful substances in the air, such as particulate matter and toxic gases, which can have severe health impacts. To gather evidence, you can use sources like the World Health Organization (WHO) or environmental agencies of different countries. Check their reports and websites for up-to-date information on air pollution levels and related health effects.
- Graphs: Look for graphs that compare air quality indexes or provide data on particular pollutants over time. These graphs can show trends, comparisons between areas, or changes in air pollution levels.
- Statistics: Various organizations provide statistics on air pollution-related illnesses, hospital visits, or premature deaths caused by air pollution. Search for relevant data to support your claims.
- Pictures: Visual representations can be powerful evidence. Look for photographs of smoggy cities, industrial emissions, or other visible signs of air pollution. These images can illustrate the impact on human health and the environment.
2. Water Pollution:
Water pollution occurs when harmful substances contaminate natural water sources like rivers, lakes, and groundwater. It is a significant global concern due to its adverse effects on human health and ecosystems. To find evidence:
- Graphs: Look for graphs showing water quality indicators or changes in pollutant levels in specific water bodies. These graphs can provide an overview of the scale and impact of water pollution.
- Statistics: Explore reports from organizations like the United Nations Environment Programme (UNEP) or environmental agencies that provide statistics on waterborne diseases, water contamination incidents, or the number of people affected by polluted water.
- Pictures: Search for images that depict polluted water bodies, waste dumping, or industrial discharge into water sources. These visuals can showcase the extent and consequences of water pollution.
3. Climate Change:
Climate change is the long-term alteration in Earth's climate patterns, primarily driven by human activities like fossil fuel combustion and deforestation. It poses various health risks globally. To gather evidence:
- Graphs: Explore climate change data from sources like NASA or the Intergovernmental Panel on Climate Change (IPCC). Look for graphs displaying temperature variations, rising sea levels, or CO2 levels over time, highlighting global trends and their impact.
- Statistics: Investigate reports from organizations like the IPCC or national meteorological agencies that provide statistics on extreme weather events, health impacts, or the vulnerability of specific regions.
- Pictures: Search for photos illustrating the effects of climate change, such as melting glaciers, drought-affected areas, or natural disasters. Visuals can help demonstrate the real-world consequences of climate change.
Remember to properly cite and attribute the evidence you use, including the source and date, to maintain credibility and reliability.
