How did the success of the cattle and sheep industries negatively affect the environment?

The sheep and cattle industries are responsible for a large amount of greenhouse gases emissions, which contribute to and accelerate climate change.

The case of the cattle industry is even more serious because cows also emit methane, which is the greenhouse gas that warms the Earth the most.

Besides, both industries cause deforestation. For example, in Brazil vast areas of the Amazon rainforest have been cut off to open room for cattle.

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).
