Question

trapping gases to the atmosphere, mainly by burning fossil fuels. these gases are called greenhouse gases. warmer temperatures are causing other changes around the world, such as melting glaciers and stronger storms. these changes are happening because the earths air, water, and land are all linked to the climate. the earths climate has changed before, but this time is different. people are causing these changes, which are bigger and happening faster than any climate changes that modern society has ever seen before. weather versus climate - weather is a specific event or condition that happens over a period of hours or days. for example, a thunderstorm, a snowstorm, and todays temperature all describe the weather. use less energy power down. did you know that some appliances and electronics plugged into an outlet still use power, even when theyre turned off? unplug energy vampires like video game consoles, cell phone chargers, and mp3 players whenever you can. or consider buying a \smart\ power strip, which automatically cuts off power when you turn off an appliance. how does this excerpt fit into the overall structure of the passage? it lists the problems caused by greenhouse gas emissions. it provides information about the dangers of greenhouse gases. it suggests ways people can reduce greenhouse gas emissions. it put blame on humans for the problems caused by greenhouse gases.

Explanation:

The excerpt talks about power - down measures like unplugging energy - consuming devices and using smart power strips. These are ways to reduce energy use, which in turn can reduce greenhouse gas emissions as energy production often involves burning fossil fuels that emit such gases.

Answer:

It suggests ways people can reduce greenhouse gas emissions.
