1. Destruction of ecosystems
2. Pollution of fresh water sources
The activities shown in the question that directly result in public health hazards are:
1. Pollution of fresh water sources: This could occur due to industrial waste being dumped into rivers or lakes, agricultural runoff entering water bodies, or improper disposal of household waste. The pollution of fresh water sources can lead to waterborne diseases and other negative health impacts for people who rely on these water sources.
2. Destruction of ecosystems: When ecosystems are destroyed, it can disrupt the natural balance of plant and animal species, leading to various consequences. This can include the loss of habitats for wildlife and the depletion of natural resources. In turn, this can have indirect effects on public health, such as the spread of diseases from disrupted ecosystems or the loss of biodiversity needed for food security and medicinal resources.
Therefore, the correct answers are:
- Pollution of fresh water sources
- Destruction of ecosystems
