Greek fires

They have been showing some awful footage of the fires in Greece. So sad , people losing their homes and livelihoods. Also the houses which have been destroyed all over Europe including the UK. A timely warning for us - we have been asked to start clearing gutters and preparing for the bushfire season which comes round every year round here. Trees are protected where I live and they are beautiful but they do pose a risk. Our house is surrounded by them so I always worry.
What can be done to prevent these events ? Perhaps, like we have to do, volunteers should be recruited on a permanent basis? Perhaps vehicle use should be restricted to help cool the environment? They do this in Beijing but then they are always ahead in so many ways. When we were there you could only use your private car on designated days.
