Before the Industrial Revolution in the 1700s, climate change was primarily attributed to natural causes such as changes in solar energy, volcanic eruptions, and natural greenhouse gas concentrations. Since then, human activities have added gases that have increased the greenhouse effect and caused Earth’s surface temperature to rise, primarily due to the burning of fossil fuels. Considering the natural changes and those based on human activities, which have consequences for all of Earth’s surface, and with the increase in urban population and the use of concrete, industrialized centers have become heat islands. What do you think this activity does to our Earth?

When you go near a fire, you may notice how it affects you and the things around you. The smoke can irritate your eyes and keep you from breathing freely. The heat from the fire can make you feel uncomfortable. Soot can cover things that are nearby. The charred wood left behind is dusty, and the smell lingers long after the fire has been extinguished. A fire can provide warmth, cook our food, and purify our water. But it can also have several undesirable by-products. Consider ways we impact Earth on a global scale. Think about billions of people driving cars. How do you think this affects the planet?

Fossil fuels are the largest emitters of what?

• methane gas

• carbon dioxide

• natural gas

• pollution

Human activities increase carbon dioxide and methane in the atmosphere.

• True

• False

Answer explanation

Humans produce carbon dioxide by using combustion engines or producing electricity. They even produce it by breathing. Human activities such as raising animals to eat as meat produce methane.
