In May 2016, in Fort MacMurray, Canada, a massive wildfire spread quickly and wreaked havoc in this northern community. In 2017, repeated fires burned down 520,000 acres of forests in Portugal. The country was devastated by the flames. Wherever they spread, fires leave their indelible imprint and sow the smell of death. With global warming, drought and extreme weather events, the threat is ever more present. How do you prevent fires and best protect biodiversity? How do you protect the environment and rehabilitate plant and animal species after fire damage? Scientists, men and women have united their strength for one and the same fight: fix nature.
