To identify and describe three environmental health hazards that cause ill health globally, we can consider air pollution, water contamination, and climate change. Let's explore each of these hazards and present relevant evidence in the form of graphs, statistics, and pictures.
1. Air Pollution:
Air pollution refers to the release of harmful substances into the Earth's atmosphere, primarily due to human activities. It has significant negative impacts on human health and can lead to various respiratory and cardiovascular diseases, among other issues. Here is some evidence:

Statistics:
- According to the World Health Organization (WHO, 2018), about 4.2 million premature deaths globally are attributed to outdoor air pollution.
- In urban areas, air pollution concentrations can exceed recommended levels by 5-10 times (WHO, 2018).

2. Water Contamination:
Water contamination occurs when water sources, such as rivers, lakes, and groundwater, become polluted with harmful substances. This pollution can arise from industrial waste, agricultural runoff, or improper disposal of chemicals. Here is some evidence:

Statistics:
- Unsafe water and poor sanitation are linked to 1.4 million deaths each year, primarily due to diarrheal diseases (World Health Organization, 2021).
- It is estimated that around 80% of the world's wastewater returns to the ecosystem without adequate treatment (UN Water, 2021).

3. Climate Change:
Climate change refers to long-term shifts in temperature patterns and weather conditions due to human activities, predominantly the release of greenhouse gases into the atmosphere. It poses numerous health risks, including heat-related illnesses, increased prevalence of infectious diseases, and food scarcity. Here is some evidence:

Statistics:
- Climate change is estimated to cause over 250,000 additional deaths per year between 2030 and 2050 due to factors such as malnutrition, malaria, diarrhea, and heat stress (World Health Organization, 2020).
- Extreme weather events, influenced by climate change, have increased significantly in frequency and intensity (Intergovernmental Panel on Climate Change, 2018).

By considering these three environmental health hazards and their associated evidence, it becomes clear that they pose significant risks to global health and require urgent attention and action.
