Chemical pollution, air pollution, climate change, disease-causing microorganisms, abject health care, abysmal infrastructure, and inadequate water quality.
Explanation:
Different chemicals can impact human health in different ways, and often, exposure to dangerous or foreign substances creates health vulnerabilities. Air pollution describes any solid or liquid particles and gases suspended in the air and have harmful or poisonous effects. Climate change disrupts the natural world in several ways that can impede health and increase vulnerability to disease; these include increases in the planet’s temperature and more frequent heavy rains and runoff. Harmful microbes, which are more commonly called pathogens or germs, can infect humans and cause illness. Individuals who don’t have access to health care services like pharmaceuticals and dental care are at a higher risk for chronic conditions, including asthma, cancer, diabetes, or heart disease. Lack of local health care infrastructure, poorly maintained roads, and lack of access to clean drinking water impacts community health. Industrial waste and pollution, lack of access to proper water treatment and sanitation services, and outdated plumbing infrastructure contribute to poor water quality.
