CO2 is a colorless, odorless gas that is naturally present in the atmosphere. It is also a byproduct of burning fossil fuels, which releases carbon dioxide into the air. The main hazards associated with CO2 are its potential to cause global warming and climate change.
Global Warming and Climate Change
CO2 is a greenhouse gas, which means it traps heat in the atmosphere and contributes to global warming. This can lead to a number of climate change effects, such as rising global temperatures, melting glaciers and ice caps, rising sea levels, and increased weather extremes.
Respiratory Effects
High concentrations of CO2 can lead to a number of health effects, including difficulty breathing, dizziness, headaches, and nausea. Long-term exposure to high concentrations of CO2 can have serious health consequences, including an increased risk of heart disease, stroke, and respiratory diseases.
Ocean Acidification
CO2 also contributes to ocean acidification, which is when the ocean absorbs excess CO2 from the atmosphere. This causes the pH of the ocean to drop, making it more acidic. This can have serious consequences for marine life, as it can have a negative effect on their ability to grow, reproduce, and survive.
