Questions: MILESTONE 4 Environmental Sci UNIT 4 - MILESTONE 4 Question 18 Mark this question Which effect of climate change will have a negative impact on human health? Temperate forests experience a net loss in biodiversity. Warming temperatures disrupt the growing season and crop planting. Unexpected flooding or droughts bring new challenges to food producers. Infectious microbes spread into places where they were previously absent. SAVE E CONTINUE Feport an lasue with this question

The answer is the fourth one: Infectious microbes spread into places where they were previously absent.

Explanation for each option:

1. Temperate forests experience a net loss in biodiversity.

   • While this is a negative environmental impact, it does not directly address human health.

2. Warming temperatures disrupt the growing season and crop planting.

   • This can affect food security and nutrition, but it is more related to agricultural productivity than direct human health impacts.

3. Unexpected flooding or droughts bring new challenges to food producers.

   • This also affects food security and can lead to economic and social issues, but it is not a direct health impact.

4. Infectious microbes spread into places where they were previously absent.

   • This directly impacts human health as it can lead to the spread of diseases to new regions, increasing the risk of infections and health problems.

Summary: The spread of infectious microbes into new areas due to climate change poses a direct threat to human health, making it the most relevant option in the context of the question.
