French President Emmanuel Macron warned Wednesday that France faced "sacrifices" in a new era marked by climate change and instability caused by Russia's invasion of Ukraine that signalled "the end of abundance".

Speaking during a televised address to his cabinet, he said: "I believe that we are in the process of living through a tipping point or great upheaval. Firstly because we are living through... the end of what could seem like the end of abundance."

Referring to the war in Ukraine, he added: "Our system based on freedom in which we have become used to living, sometimes when we need to defend it, it can entail making sacrifices."
