Nitrous oxide (N2O)
This chemical is produced from combustion; it’s also produced as a result of agriculture treatments like soil treatments and fertilizer. Use natural fertilizers and buy organic to reduce these harmful emissions.
Many aerosols like hairspray, solvents, refrigerants and other propellants use HFCs or Hydrofluorocarbons. They deplete the ozone. These are easy to reduce by simply not using them.
