Which of the following does not contribute to elevating Methane levels?a.Raising Cattleb.Using fertilizersc.Extracting fossil fuelsd.Creating Landfills

All of the options listed (raising cattle, using fertilizers, extracting fossil fuels, creating landfills) contribute to elevating Methane levels.

a. Raising Cattle: Cattle release methane as part of their digestion process in a phenomenon known as enteric fermentation.

b. Using fertilizers: The use of synthetic fertilizers in agriculture can lead to the release of methane when organic matter in the soil decomposes under conditions where oxygen is limited.

c. Extracting fossil fuels: Methane is a primary component of natural gas. During the extraction, processing, storage, transmission, and distribution of fossil fuels, methane can be released into the atmosphere.

d. Creating Landfills: Landfills are a significant source of methane because when organic waste breaks down in an environment without oxygen, it produces methane.

Therefore, all of the options listed do contribute to elevating Methane levels.
