Blended learning, also known as hybrid learning or mixed-mode learning, combines traditional face-to-face teaching with online learning experiences. That way of learning offers several benefits to both students and educators. Firstly, Blended learning provides flexibility for students to learn at their own pace and at a time and place that suits them. Students can access course materials and lectures online and study at their convenience, which is especially helpful for adult learners or students with busy schedules. Secondly, Blended learning can be a cost-effective option for educational institutions. Digital resources can reduce the need for physical textbooks and other materials, and online courses can be delivered to a larger number of students at a lower cost than traditional classroom-based courses. Overall, blended learning combines the best of both worlds: the personal touch and expertise of traditional teaching, with the flexibility and interactivity of online learning

Tourism is a unique human activity, experienced by millions of people worldwide every year. As people differ in their attitude towards almost everything in life, the same applies also to tourism; where some treat tourism globally as the focus of their act without scrutinising the other related activities pertaining to it. Hence, the term 'responsible tourism" emerged; in order to pay a sufficient attention of the tourist to the local cultural values of the destination country, and – more globally – to the environment. From my point of view, tourism must be labelled as a "responsible activity"; even if it is mandatory to issue as many local and international legislations to make it so.

While making tourism, should the tourist carry his culture with him to the foreign country? Obviously, the answer is "No". If the tourist insists on doing this, he will sure subject himself to great dangers especially in communities with intolerant local citizens. One of the best examples of this is the "Thump Up" sign which is greatly practised in many countries; where this sign is USA means "OK or very good"; while it is considered as very crude and impolite in Greece (which is a famous touristic destination). Thus, it is crucial to teach the tourists a list of common practices that they must refrain from doing, explaining the reasons behind this.

When it comes to the environment, it is indeed very unfortunate to find that the touristic areas are those with the greatest pollution and litter output! A few years ago, it was really surprising that an international campaign of volunteers aimed to clean the Himalayas from the trash left by the climbers.

In conclusion, tourism should be dealt with in the same way as freedom; that it must be "responsible", respecting both the local cultural and environmental values of each society.
