Blog 30 – Do The Maths

TREES PLANTED

I went to see Bill McKibben last Friday when he was in Melbourne ‘rallying the troops’ with his Do The Maths tour.  Very engaging (but alas not techno savvy) he painted a very sobering message to a packed Atheneum Theatre.He had just 3 numbers he wants us to be aware of …a. The number 2. This is how many degrees we DO NOT want our world average temperature to increase by. At present, we are almost at 1oC increase and already can see the affects across the world.b. The number 565 (gigatons). This is how much fossil fuels we can burn if we want to keep below the 2oC increase.c. The number 2795 (gigatons). This is how much mining companies around the world have in their reserves and planning to burn. That is 5 times over the safe amount.[fusion_builder_container hundred_percent=”yes” overflow=”visible”][fusion_builder_row][fusion_builder_column type=”1_1″ background_position=”left top” background_color=”” border_size=”” border_color=”” border_style=”solid” spacing=”yes” background_image=”” background_repeat=”no-repeat” padding=”” margin_top=”0px” margin_bottom=”0px” class=”” id=”” animation_type=”” animation_speed=”0.3″ animation_direction=”left” hide_on_mobile=”no” center_content=”no” min_height=”none”]

Bill spoke of Clive Palmer who want to extract so much gas and coal that he will destroy our beautiful Queensland. And for what ?? So he can build a replica of the Titanic with his massive profits.The problem seems overwhelming until ..You realise how much power we have if we Divest our money (e.g. Super) into ethical investments (great Forbes article here on divesting).And over at A Vital Few,  you can send off a letter to your own super fund with a few clicks of your mouse. They have made the process so easy. The generic letter can be modified to suit yourself and it goes straight into the inbox of your Super provider.It isn’t too hard to do some investigative work and start asking where your money is being invested.Slainte – Colleen[/fusion_builder_column][/fusion_builder_row][/fusion_builder_container]

There’s something quietly powerful about a person who decides, on their own, to do something good for the planet. No fanfare, no corporate mandate – just a simple choice to put a few trees in the ground. When hundreds of individuals make that same choice, something remarkable happens. Native forests are restored, wildlife corridors are rebuilt, and community groups across Australia get to do the work they love. So if you’ve ever purchased trees through Fifteen Trees, thank you.

‘Tree planting is about far more than restoring the landscape, it’s about bringing people together to care for the places we all value. Thank you for your generous support for the farmers, students, volunteers and conservation partners who are helping create healthier habitat for Tasmania’s unique wildlife while inspiring the next generation of environmental stewards’.
