Read the passage and answer the questions that follow.

The greatest threat to life on Earth today comes from global warming. This is caused due to multiple factors including human activity. It happens when greenhouse gases (carbon dioxide, water vapour, nitrous oxide, and methane) trap heat and light from the sun in the earth's atmosphere, which increases the overall temperature on Earth. This impacts people, animals, and plants. Many who cannot take the change, die. Global warming is affecting many parts of the world, particularly sea coasts. People living on islands and in coastal areas are therefore at risk as the polar ice caps and sea levels rise.

According to the passage, select the statement that is false.

ALife on Earth is threatened only by global warming.
BGlobal warming threatens human beings who live on islands.
CWhen the overall temperature on Earth rises the sea level will also increase.
DCreatures that cannot adapt to higher temperatures will become extinct.
