A Correct answer
Explanation

Agriculture's Green Revolution helped meet the world's increasing demand for food, but it also contributes to a warming planet. With the advent of the Green Revolution (1940s- ‘60s), agricultural practices have expanded and intensified. As these revolutions led to the domestication, diversification, and plant reliance on fertilizers and pesticides, the emission of greenhouse gases increased, and is still rising. It is known that these greenhouse gases, like carbon dioxide, methane, and nitrous oxide, contribute to climate change.Since these gases are emitted from agricultural practices, global warming may be influenced by more factors than the general public is aware. It can be concluded that previous agricultural advancements have been beneficial in supplying food, but while they are feeding the growing human population, agricultural practices are also feeding global climate change. 

So, the correct answer is 'Green Revolution'.
