These stars are serious about saving the environment

The actor doesn't follow environmental trends, he sets them: Leonardo DiCaprio has been involved with his own foundation for environmental protection since 1998. Since then, the vegetarian has produced documentaries, financed a racing team in the electric motor league and bought an island for his own eco-resort. He has been a UN peace ambassador in the field of climate protection since 2014.

The 29-year-old actress best-known for appearing in Harry Potter films promotes sustainable fashion on the red carpet at film festivals and premieres. It's a good strategy, since the press always ask whose design she's wearing. Watson has been involved in making garments from recycled plastic bottles (as seen in the photo), recycled fabrics and organically produced silk.

The Danish-Icelandic artist has worked with nature for many years. To bring awareness to climate change, he brought huge blocks of glacier ice to the Tate Modern in 2016, which melted before the eyes of Londoners. In 2012, he created "Little Sun," a solar-powered lamp for households in sub-Saharan Africa that are not connected to the power grid.

The eternal heir to the throne has long been committed to organic farming, including on his own estates and farms. His strong convictions, for example, that the outbreak of BSE — commonly known as mad cow disease — in Great Britain was "nature's revenge," have prompted many discussions. He constantly warns against genetically manipulated food and often doesn't agree with the prime minister.

The son of an environmental lawyer and a conservationist, it's no surprise that the actor is bent on saving the environment. In 2003, he started a project to put solar panels on Hollywood homes and later founded an organization to preserve ecosystems in Africa through conservation projects that benefit indigenous communities. Norton has been the UN Goodwill Ambassador for Biodiversity since 2010.

In 2004, she saw how indigenous communities in the Amazon struggle with polluted rivers. It was the initial spark for her own water conservation project and other nature conservation activities. She has been the UN Special Envoy for Environmental Protection since 2009, and the proceeds of the collection she designed for the legendary flip-flop brand Ipanema are donated to environmental projects.

He plays, produces, sings (in his own country band), dances with the wolves — and invests. He's invested several million euros in so-called centrifuge technology. Together with his brother, a scientist, he promotes the development of machines that clean oil-contaminated water. These machines are said to have been used during the oil spill in the Gulf of Mexico in 2012.
