In honor of his birthday, Charles served as a guest editor for Country Life magazine for the third year in a row. In his article, he encouraged readers to recognize hope despite a difficult year.

"The country, and the world, have experienced changes we could never have foreseen," Prince Charles wrote. "Uncertainty has become a steady state; the previously unimaginable has become unexceptional; the extraordinary has become normal. At such a time, it is tempting, and understandable, to focus on the losses, the failures and the challenges. However, if the life of the land teaches anything, it is the need to look at the long term."

Queen Elizabeth's eldest son and heir, who has been a strong advocate for conservation for decades, praised "the strength of our society: its resourcefulness, its compassion and its stoical determination" amid the coronavirus pandemic — and wants to apply the same traits to the fight against climate change.

"Like the threatened red squirrels collecting their hazelnuts or jays their seeds and acorns, we must be wise and far-sighted," he said, thinking of the next generations of his family. "We have a very short window of opportunity, which must not be squandered, in which to seize something good from this crisis and, as we rebuild, to put Nature, our planet and our children and grandchildren first."
