Green Matters: How Does Climate Change Affect Human Health? Scientists Weigh In. Climate change affects our weather patterns, sea levels, wildlife populations, and global temperatures, but very few people understand the ramifications it’s had on the human population. Believe it or not, our food, water, and air quality have all been seriously affected by climate change, and as a result, climate change has affected human health in a number of dangerous and potentially deadly ways. Sadly, it will continue to do so as global warming worsens.
How does climate change affect human health?
Human beings are among the many lifeforms affected by climate change, though ironically, global warming was completely brought on by human activity. For example, air pollution is the root of many human health problems, while deforestation has destroyed many of the trees sequestering CO2 emissions. Water pollution affects our food and water supply on a daily basis, high temperatures lead to droughts — which deprive communities of drinking water — and the melting ice caps endanger seaside communities daily.
