Tourists watching whales in Puerto Madryn, Argentina. File photoBUENOS AIRES, Oct 14 The number of southern right whales found dead in southern Argentina has risen to 30, the Whale Conservation Institute told RIA Novosti. «The number of (dead) whales has risen to 30» , the institute said. 
Eighteen whales found dead in southern Argentina Twenty-six adult whales and four juveniles were found. Earlier it was reported about 18 dead animals. The body of the first of them was discovered on September 24. Currently, scientists are working on versions of the causes of death. A poisoning hypothesis from harmful algal blooms is being explored, as very high levels of biotoxins have been found in plankton and bivalve samples from the area. Poisonous algal blooms are a worldwide problem. So, in 2015, they killed 300 whales in Chile from sending them. Human activity is directly related to the flowering of these poisonous algae on the coast, which is stimulated by rising ocean temperatures, emissions from industries and agricultural fields where fertilizers are used. The bodies of young and adult whales were discovered in the region of the Valdez Peninsula — places where every year from June to December thousands of tourists come to admire these giants of the ocean. Whales come here to have offspring or feed their newly born cubs. This is the only place in Argentina where tourists can get within arm's reach of whales.
