Exponential growth of tourism

In 1950 there were 25 million international tourist arrivals, in 1970 the number was 166 million, and by 1990 it had grown to 435 million. From 1990 to 2018 numbers more than tripled reaching 1.442 billion. By 2030, 1.8 billion tourist arrivals are projected.

Negative environmental impacts of tourism

The negative environmental impacts of tourism are substantial. They include the depletion of local natural resources as well as pollution and waste problems. Tourism often puts pressure on natural resources through over-consumption, often in places where resources are already scarce.

Tourism puts enormous stress on local land use, and can lead to soil erosion, increased pollution, natural habitat loss, and more pressure on endangered species. These effects can gradually destroy the environmental resources on which tourism itself depends.

Tourism often leads to overuse of water

An average golf course in a tropical country, for example, uses as much water as 60,000 rural villagers. It also uses 1500 kilos of chemical fertilizers, pesticides and herbicides per year.

Tourism and climate change

Tourism contributes to more than 5 percent of global greenhouse gas emissions, with transportation accounting for 90 percent of this.

By 2030, a 25% increase in CO2-emissions from tourism compared to 2016 is expected. From 1,597 million tons to 1,998 million tons.

The alternative: Eco-tourism

Eco-tourism offers a greener alternative. Eco-tourism is a rapidly growing industry, with potential benefits for both the environment and the economies of the tourist destinations.
