What is the largest concern we have with adding too much CO₂ to the atmosphere?

• makes too many clouds
• contributes to a warmer planet
• affects our breathing
• disrupts solar energy

One disadvantage to using coal to produce electricity is that coal -

• forms in a short amount of time.
• is abundant over a wide area.
• is not environmentally friendly.
• is relatively quite affordable.
