Behind the scenes of the BBC animal series

Filming in nature isn't easy. And things get even more complicated when you want to capture a courtship. You have to lie in wait for hours, days, or weeks to catch the right moment. And the conditions are always challenging. The footage will show the documentary makers in torrential rains, at night, devoured by mosquitoes, or among salmon, having to watch out for bears. It's a fitting tribute to those who not only create unique films, but also provide insights into nature, helping to save it. Barbara Bernardini's report, meanwhile, tells the story of a girl cured of liver disease thanks to gene therapy. The focus is also on organic waste and agricultural residues, among the most difficult to dispose of. In Italy, some cutting-edge plants demonstrate how it's possible to manage disposal while respecting the environment and transform this waste into new materials for reintroduction into the market.
