Humans raise large numbers of cattle for food. how will these herds of cows affect
earth's atmosphere?

A herd of cows releases large amounts of methane, which is extremely damaging to the atmosphere.

Explanation:

It may seem like a joke, but the production of beef - especially the flatulence of cows - has a greater responsibility in the emission of greenhouse gases than the amount of gas emitted by automobiles. The digestion of cattle causes methane (CH4) gas to be released into the atmosphere, this gas is released in large quantities and is extremely harmful to the atmosphere. Like carbon dioxide (CO2), the result of burning fossil fuels, methane accelerates the greenhouse effect process, which causes the temperature on the planet to increase every year.

the oceanic zone is typically defined as the area of the ocean lying beyond the continental shelf, but operationally is often referred to as beginning where the water depths drop to below 100 meters (328 feet), seaward from the coast to the open ocean.
