Who is Enric Sala?

Enric Sala is an expert on marine conservation and is currently the National Geographic Society's Explorer-in-Residence. His love of the sea started with his childhood in Spain, inspired by the example of the legendary diver Jacques Cousteau. He has been a university professor of Oceanography in the US, as well as working at the Spanish National Council for Scientific Research and is a member of the World Economic Forum’s Global Future Council on Biodiversity and the Bio-Economy. He has dedicated his life to protecting life in the oceans. Enric describes himself as a flexitarian who only eats meat occasionally.

What is biodiversity?

According to the United Nations Environment Programme, all life on earth – including in its forests and oceans – forms a “rich tapestry of interconnecting and interdependent forces”. Biodiversity on earth today is the product of four billion years of evolution and consists of many millions of distinct biological species. The term ‘biodiversity’ is relatively new, popularised since the 1980s and coinciding with an understanding of the growing threats to the natural world including habitat loss, pollution and climate change. The loss of biodiversity itself is dangerous because it contributes to clean, consistent water flows, food security, protection from floods and storms and a stable climate. The natural world can be an ally in combating global climate change but to do so it must be protected. Nations are working to achieve this, including setting targets to be reached by 2020 for the protection of the natural state of 17 per cent of the land and 10 per cent of the oceans. However, these are well short of what is needed, according to experts, with half the land needed to be in a natural state to help avert disaster.

UAE-wide visa changes: Expats imagine life after work in the UAE

Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday. 

Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow. 

She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.

A spokesman said her upset demeanour was due to a personal matter.
