London’s five billion pound Super Sewer is now fully connected and promises a cleaner, healthier River Thames. The 150-year-old sewer network has struggled to cope with the twin challenges of an increase in the population it serves in the capital (from four million people when it was built to over nine million today) together with climate change. With rainfall overwhelming the system, it sometimes discharges into the Thames. With the Super Sewer fully connected, 95% of those spills are stopped.

The Linnean Society is one of a number of learned societies that have made Burlington House their home. It was founded in 1788 by the amateur botanist Sir James Edward Smith who, spurred on by the President of the Royal Society, Sir Joseph Banks, purchased the natural history collection of the Swedish naturalist Carl Linnaeus, who is known as the father of taxonomy - the classification and naming of biological organisms based on shared characteristics.

The Royal Family of the United Kingdom is financed in a number of different ways. Its main source of income is the Sovereign Grant (the Civil List until 2012), which currently costs £86.3 million a year. This comes in the form of a grant from the government that meets the costs of the royal residences, staffing, travel and state visits, public engagements, and official entertainment.
