The quantity of methane produced from these sources each year shows that with the increase of the population, animal number and human activities the concentration of methane in atmosphere is growing rapidly. The measurement of the glacial cores proves that the annual production of methane was increased by 0.2% betweem 1840 and 1890 and 1925, and 1% between 1925 and 1950. The increase speed of methane is compatible with the speed of the consumption of fossil fuels. Along with the growing population, animal number and use of fossil fuels, the concentration of methane in the atmosphere will also increase in the future.
