Environmental hazards—such as water and air pollution, extreme weather, or chemical exposure—can affect human health in many ways, from contributing to chronic diseases such as cancer to acute illnesses such as heat exhaustion.
There is a link between the environment and the health of individuals and communities.
Humans can affect the health of the environment
- An environmental health hazard is a substance that has the potential to cause an adverse health event.
- This includes physical, chemical and biological factors that are external to humans.
- Hazards can be natural or man-made.

Answer:
The correct answer is carbon dioxide.
Explanation:
Respiration (physical) process involves inhalation and exhalation of oxygen and carbon dioxide respectively in between the air and into the lungs to the blood. If the brain receptors sense the excess amount of carbon dioxide in the blood, they send signals the body to promote ventilation. So, the most important chemical regulator of respiration is carbon dioxide that determines the respiratory rate.
An increase in carbon dioxide concentration in blood results in a decreasing pH level of the blood, causing the person to increase his rate of ventilation.
Thus, the correct answer is carbon dioxide.
The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body.
Lisa may have an infection. The fever may also be a sign of inflammation caused by the injury to the cardiac tissues probable during a heart attack.
The symptoms of a heart attack include chest pain, shortness of breath, weakness, fainting, and more. The inflamed cardiac tissues can be a result of a heart attack that led to fever. Fever is also a response of the body to combat an infection. Again, a bacterial infection called Anthrax is likely to produce symptoms like a heart attack, accompanied by fever. Anthrax is caused by the pathogen <em>Bacillus anthracis</em> and spreads by contaminated vegetation. However, the correct cause of Lisa's symptoms can only be identified upon testing patient samples.
