What is one way intensive agricultural practices contribute to climate change?

The intensive agricultural practices contribute to the climate change because of the usage of fossil fuels. Most of the machines used in the agriculture use fossil fuels, so the more they are sued, the more CO2 ends up into the atmosphere. The more CO2 ends up into the atmosphere, the greater the Greenhouse effect. The CO2 is a gas that has the property to trap the heat, thus instead of letting it out from the atmosphere it keeps it inside, thus warming up the climate. It has to be noticed that the agriculture is one of the lesser contributors to the climate change, and it is far behind the bigger contributors.
