This is the text (if you need help).
Climate scientists say tourism causes over 8 per cent of greenhouse gasses. This figure will increase. Their study looked at the CO2 emissions from transport, hotels, restaurants, shopping, etc. Researchers looked at tourism in 189 countries. They studied the effect of over one million tourism businesses.
Domestic travel caused more CO2 emissions than international travel. Air travel caused the most. The countries with the biggest tourism carbon footprints were the USA, China, India and Germany. Their emissions will increase because more of their citizens will travel. Travelers should cut their carbon footprint to help Earth.
