With regard to the humanitarian crisis in the Mediterranean Sea, Mr. Ban welcomed “with satisfaction the measures announced last week by the Heads of State and Government of the European countries,” on the Mediterranean crisis. “They represent an important first step towards European collective action,” he added at a joint press conference with French President, François Hollande.“This is a humanitarian crisis, not a safety issue. We need to defeat the criminals who are trafficking in human beings. But we must also concern ourselves with the root causes of migration, so that people are not forced to leave their homes,” the UN chief added.“If there are so many migrants, it is because people fleeing war and persecution. Violent extremism is fuelled by conflict and poor governance.”The Secretary-General said that to “confront this threat against global security; we must deploy comprehensive and complex solutions. In a few months, I will present to the General Assembly at its 70th session, a plan to fight against violent extremism.”Mr. Ban also delivered a speech to students of the Institute of Political Studies in Paris, where he encouraged students to express themselves and become global citizens.He urged them to take action on climate change and welcomed initiatives to organize momentum for the upcoming conference on the issue, which will be held later this year in Paris. “Young people have more ideas and I really count on your commitment,” said the Secretary-General. “The world must find ways to adapt to the changes already underway.”“We will need to do is considerable resources. Developed countries must clear path that will allow them to collect 100 billion by 2020 to finance climate action in developing countries. And the Green Climate Fund should start operating effectively and making payments before we meet in Paris,” he emphasized.
