But everything was about to change.One day,the greenhouse gases showed up in the atmosphere.
The ability to absorb heat helped warm the earth to a comfortable temperature to support life.
As humans start to populate the planet, their demand for energy grows. As they start to use electricity from coal-fired power plants and gasoline to power vehicles, the amount of greenhouse gases going into the atmosphere starts to increase
If large amounts of greenhouse gases accumulate in the atmosphere, the heat cannot get out and the earth's temperatures increase.The rising temperatures will affect the ecosystems, climate, and human life. THE END
