Ecologists have described how tourists can destroy the planet

About eight percent of greenhouse gas emissions, human-induced, account for tourism. To such conclusion the international group of researchers representing the University of Sydney in Australia and national University of Cheng Gong in China. Thus, the travelers significantly accelerate global warming and hasten the onset of its possible adverse effects.

Experts analyzed the information about what goods and services were used by tourists in 160 countries in the period from 2009 to 2013 and calculated the extent to which this has led to air pollution of greenhouse gases. Although carbon dioxide is not the only such gas, the impact of other substances equated to the amount of carbon dioxide that would have on the greenhouse effect same effect. Thus, the total emissions are directly related to the journey, compared to 4.5 gigatons of carbon dioxide equivalents, equivalent to 8 percent of all greenhouse gases of anthropogenic origin released to the atmosphere during this period.

Experts explain that it is, primarily, the emissions of vehicles that move travelers and transported goods needed to maintain the tourism infrastructure. Scientists assume that the results obtained can be partly explained by the fact that governments are much more willing to develop tourism than “green” energy. The researchers noted that island and coastal communities, where tourism is often an important source of income, can suffer from the effects of global warming in the first place.

The study was published in the scientific journal Nature Climate Change.

Recently, experts said that last April the average concentration of carbon dioxide in the Earth’s atmosphere has reached 410 parts per million, which is a record. The symbolic mark of 400 parts per million concentration of carbon dioxide for the first time in 800 thousand years overcame in 2013.
