Question

Each year almost _____ metric tons of carbon dioxide are released into Earth's atmosphere

Answer 1

Over 30 billion metric tons of carbon dioxide are released into Earth's atmosphere each year due to human activities.

Step-by-step explanation:

The amount of carbon dioxide released into Earth's atmosphere each year is over 30 billion metric tons. Human activities, such as the combustion of fossil fuels and deforestation, are the primary contributors to this increase in carbon dioxide levels. This human-caused build-up of carbon dioxide is leading to a slow but steady increase in atmospheric carbon dioxide levels, which have already risen by approximately 30% since 1850.
