Saving the Planet

I note with interest that the Scottish Government agreed a 42% cut in greenhouse gas emissions by 2020, is this true 20x20 vision?

We are a small country but Scotland has always punched above it's weight, and I hope others will follow.
The one good thing about getting older is that you have an abundance of hindsight, and hopefully a little bit of accrued wisdom as well.
I'm only in my sixties but when i was a kid, our milk still got delivered by horse and cart, there were very few cars, no plastics, no TV, no phones for the masses, gas street lighting, no central heating, no running hot water, outside toilets, rationing for everything, and peoples dustbins only contained dust ! Nothing was thrown away, because people had nothing to throw away !
It's hard to get the younger people to realise just how hard life was, just surviving was an achievement in itself.
I can scarcely believe how much the world has changed in the last 50 years, and this is not a long time believe me!
I have no doubt whatsoever that the human race is over consuming, to such an extent that we need 3 planets to sustain the way we live our lives. As you all know we only have one Planet and have no alternative but to start living within our means. This is an absolute truth, both individually and collectively.
The whole reason we are in this global economic recession is precisely because we have not been living within our means.
Understanding the human condition is the first step in recognising where we have all gone wrong.
In my experience i believe that human beings have a built in self destruct button, even if they don't realise it. That self destruct button is quite simply the desire for MORE, it might manifest itself in more money, more power, more clothes, more shoes, more recognition, more fame , more control, more drink, more drugs - you name it, we want more of it !
On this basis, collectively the world is pushing the self destruct button, this has to stop !
We need internationally binding agreements written in stone.
A radical rethink of what we are and where we should be going is needed. All of us should be asking ourselves relevant questions about how we live - like, do i really need 2 or 3 hundred horsepower to go a mile down the road ?
Maybe a whole new strategy of national pedestrianisation should be introduced in all seaside towns and holiday resorts ? This could solve a lot of problems, reduce greenhouse emissions, boost trade, improve peoples health, reduce noise and many other benefits.
Having come from an age without cars believe me we can survive happily without them !
In addition to all the other actions we can take on fuel efficiency, better green homes etc, we do have to change our outlook and attitide to ourselves and all other species that share this planet with us.
With our MORE culture, we are the most destructive species on the planet.
