The concentration of atmospheric carbon dioxide is currently decreasing due to human activities?
true or false

 human activities make the amount of CO2 released into the atmosphere  rise especially during the last 150 years. As a result, it has exceeded the amount sequestered in biomass, the oceans, and other sinks.knowing this you can say that the answer is false

Iwould say silver and gold

Gases enter the atmosphere and trap the sun's heat warning the earth.
