"Tourism can be domestic (within the traveller's own country) or international."
"International tourism has both incoming and outgoing implications on a country's balance of payments."
"Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus."
"The United Nations World Tourism Organization estimated that global international tourist arrivals might decrease by 58% to 78% in 2020."
"Leading to a potential loss of US$0.9–1.2 trillion in international tourism receipts."
"International tourism receipts (the travel item in the balance of payments) grew to US$1.03 trillion (€740 billion) in 2005, corresponding to an increase in real terms of 3.8% from 2010."
"International tourist arrivals surpassed the milestone of 1 billion tourists globally for the first time in 2012."
"Emerging source markets such as China, Russia, and Brazil had significantly increased their spending over the previous decade."
"Global tourism accounts for c. 8% of global greenhouse-gas emissions."
"For this reason, many tourist development organizations have begun to focus on sustainable tourism to mitigate the negative effects caused by the growing impact of tourism."

"The International Year for Sustainable Tourism for Development was in 2017."
