Script? of my speech (2) If I talk about all the biodiversity that lives in Mar Menor, we could stay here for two or three days, but we are not biologists and we haven’t got time. Doing a quick review, the most important animals are gilt-head bream, mullets, prawns, jellyfish and seahorses. This last is in danger of extinction because tourist catch (or sell) them as souvenirs. In wetlands and sand areas the birds find a place to stop on their migratory route, a breeding place or a place to live permanently, for example the most common are flamingos in Salinas of San Pedro, seagulls and herons. In order to plants, here are is composed of salt cedar, European fan palm, gum rockrose, salicornias, sand lily and reeds, among others. Here we can see some of them. These natural spaces are of vital importance and are protected. Salinas and Arenales of San Pedro del Pinatar and Special Protection Area for Birds (SPA) (ZEPA) are protected space. There is some nature park as this that you can read here. At last, we have to remark seaweed (there are about 80 varieties) and marine plants, such as oceanic posidonia. It is very important, as well they filter important amounts of suspended substances in the water, generating a purification and cleaning effect of the lake. Briefs, Mar Menor is a fundamental place to the economics in Region of Murcia. Tourists look for sun, beach, relax and also water sports. Tourism is classified in two categories: people staying in tourist establishments (20%) and tourist with second residence (80%). To exemplify this relevance, the four municipalities pointed before have 50% of the hotels in the region, almost 65% of the camping and the 83% of the apartments of the total amount in each category. Now, we are going to the main point of the speech. In natural terms, the most important causes of the environmental problem are the climate change and the degradation of the surrounding wetlands, which filter the lagoon. About the climate change, last winter had one of the warmest temperatures in the last years, so the sea can not regenerate properly. Manmade disaster is the principal problem. For example, the accumulation of organic waste of intensive agriculture in the area, the increase in aquaculture, the elimination of jellyfish to please the bathers.
