Answer:
The given statement is false.
It is because the greenhouse effect is a natural process which takes place in the environment by its own.
The greenhouse gases trap the heat energy coming from the sun and the energy which is radiated from the earth and helps in keeping the earth warm.
Natural processes such as volcanic eruptions, cellular respiration, forest fires, transpiration, decomposition et cetera produce greenhouse gases such as carbon dioxide, water vapors, methane et cetera.
The activities of humans increase the effects of the greenhouse effect however, they are not the sole reasons for this natural effect.
