Final answer:
Climate change affects tourism through shorter ski seasons, damage to marine ecosystems, and extreme weather events.
Step-by-step explanation:
Climate change affects tourism in several ways. Firstly, shorter ski seasons and damage to marine ecosystems can lead to a reduction in tourism. For example, if there is less snowfall and melting glaciers, ski resorts may have shorter seasons and attract fewer visitors. Additionally, the impact of climate change on agricultural outputs can lead to changes in crop growth and quality, which may weaken the agricultural industry and affect agritourism. Lastly, extreme weather events caused by climate change, such as hurricanes and heatwaves, can disrupt travel plans and discourage tourists from visiting certain areas.
