Although there are many benefits to tourism, they are mainly personal benefits for those who get to travel.

Tourism can lead to the creation of jobs (even though people who work in this field are usually underpayed) , it can help to preserve historical buildings and it comes with finantial benefits but they mostly go into the hands of the few who are rich enough to have businesses that allow them to proffit off this industry.

So in conclusion, those who aren't proffitting off the tourism sector are actually loosing.

When it comes to tourists in particular, there's multiple social problems:

tourists tend to treat locals as photo props (for example travelers in Africa take photos with African children as if they were objects),

they also pertake and help exacerbate animal explotation (for example in Asia tourists ride elephants that have to endure torture to be trained or they visit tiger zoos to take pictures but for them to do so the tigers have to be drugged). This animals are not meant to be vehicles or used as accessories in photos, they are meant to be free in the wild.

In and out mass tourism is responsible for the destruction of ecosystems, noise pollution, sewage generation, increase in garbage waste, water depletion, and consuming animals in tourist destinations can lead to the endangerment or even extintion of those species. Tourism also generates inflation (especially in poor countries) and due to the cost of living rising it becomes almost impossible for locals to afford living in their own country.

The aviation industry is responsible for 4,9% of manmade global warming. Although planes are only used by 10% of the human population, they cause 12% of all transport emissions (of which CO2, O3 and CH4).Unlike other fuels, kerosene (used by planes) is not taxed so the aviation industry recieves massive subsidues.

Besides hurting the environment, this industry is also using politics that assault alternative sustainable modes of transport (like cross border trains) and has also lobbied it's way out of the Paris agreement. Aircraft manifactures are linked to the oil and war industrial complex. When it comes to Airbus specifically, 20% of their sales are from military equipment and when it comes to Boeing it's 50%.

Some people, when they take a flight, they choose to reduce their impact by offsetting their flight. Carbon offsetts are voluntary schemes where people pay to make up for the emissions that their flight produces. Unfortunately it is for the most part green washing, (companies attempt to make themselves look eco-conscious to persuade the public into thinking they are environmentally friendly)the emissions that are offset through projects in the global south, for example hidroelectric dams, lead to the displacement of local people and the destroyment of ecosistems. To sum up, the companies that are proffitting off of the aviation industry are also proffitting off the war industrial complex, the displacement of local people and the destroyment of ecosistems.

A huge problem with the fact that more and more people are traveling and going on vacation is the Airbnb effect.

Many cities now have been turned into hotels created for the accomodation of tourists. Unfortunately they are not much accomodating to the local residents and that is leading to the rise of rent prices, rise in property, it is also destroying the business of small hotels or inns and is leading to unemployment due to the fact that many Airbnb owners do the cleaning themselves so they don't need any staff, whereas a local hotel or an inn would have cleaners, receptionists, staff and employed people.

On the other hand multinational conglomerate hotels can also lead to the degradation and loss of ecosystems from improper development of infrastructures such as sand and beach mining, encroachment into natural habitat of plants and animal species and also deforestation.

In one day the average cruise ship emits more soot than one million cars. In one week almost 5,680 litres of human sewage. You read that right, and now you are probably thinking "that's a lot!". Yes, it is and we are only talking about one cruise ship. Now imagine what a huge amount of sewage ends up in our oceans and how it can affect the resilience of coral reefs and other marine ecosystems. The cruising industry is not only causing water pollution and destroying marine life but in fact, it is responsible for an increase in air pollution in costal cities and is causing an increase in deaths from respiratory illness.
