Because ammonia production depends on a reliable supply of energy, fossil fuels are often used, contributing to climate change when they are combusted and create greenhouse gasses. [11] Ammonia production also introduces nitrogen into the Earth's nitrogen cycle, causing imbalances that contribute to environmental issues such as algae blooms.
A historical (1921) high-pressure steel reactor for the production of ammonia via the Haber process is displayed at the Karlsruhe Institute of Technology, Germany Combined with the energy needed to produce hydrogen and purified atmospheric nitrogen, ammonia production is energy-intensive, accounting for 1% to 2% of global energy consumption , 3 ...

Services accounted for 58.2% of Sri Lanka's economy in 2019 up from 54.6% in 2010, industry 27.4% up from 26.4% a decade earlier and agriculture 7.4%. [41] Though there is a competitive export agricultural sector, technological advances have been slow to enter the protected domestic sector. [42]
