<s>[INST] The next text is a question of a member of the European parliament:"InOctober of this year an international conference convened by the World Tourism Organisation on sustainable tourism in small, developing island states and on other islands was held in Lanzarote. Speakers at the conference warned of the potential environmental problems associated with the increasing interest amongst tourists in small islands whose capacity to cope with visitors is limited, and the consequent danger of their becoming overcrowded with tourists.  Many of the hundreds of small islands which belong to EU Member States have built up a large tourist industry which, whilst offsetting the decline in traditional sectors of the economy, has also created serious difficulties, including excessive and chaotic urbanisation, waste production and other environmental problems.  Is the Commission aware of the problems peculiar to these island regions, caused by the growth of the tourist industry?  Does it intend to look into, or experiment with, measures designed to introduce into these fragile areas sustainable development strategies capable of combining the conservation of their natural resources with a sensitive form of tourism which values such conservation?"
