Geography of New Zealand are generated by greenhouse gases, mainly methane and nitrous oxide, which come from farming and agriculture. Organisms that grow inside of grazing animals' stomachs turn New Zealand's grass into methane. The increase of carbon dioxide in the air helps the plants to grow faster, but the long-term effects of climate change threaten farmers with the likelihood of more frequent and severe floods and droughts. Growers of kiwifruit, a major export in the horticulture industry of New Zealand, have experienced difficulties as a result of climate change. The recent warm winters are not providing the adequate cool temperatures needed for the
Nitrous oxide B levels should be checked in people with risk factors for vitamin B deficiency prior to using nitrous oxide anaesthesia. Several experimental studies in rats indicate that chronic exposure of pregnant females to nitrous oxide may have adverse effects on the developing fetus. At room temperature (20 °C (68 °F)) the saturated vapour pressure is 50.525 bar, rising up to 72.45 bar at —the critical temperature. The pressure curve is thus unusually sensitive to temperature. Liquid nitrous oxide acts as a good solvent for many organic compounds; liquid mixtures may form shock sensitive explosives. As with many strong oxidisers, contamination
