I´m still amazed by humans ability to think incredibly short-sighted. How is it possible to ignore scientific knowledge because we have comfortable and cheap solutions within reach? How can it be so difficult to understand the need of sustainability?
It´s quite logical really, the math is pretty straight-forward. I will repeat it, just in case. It all boils down to one thing: we don´t have more than one globe. The consequence is: we can´t use more than the limited resources accessible. One plus five never equals one.
So we should use the resources available to develop sustainable solutions, which will last despite of population growth. Renewable will deliver energy for years and years ahead because we already have an unlimited power supply: the sun. In my eyes, developing yet other methods for squeezing the last drops of oil out of the already exhausted soil is madness. What we need is to think further than profit next year or decade, steering towards the "plan ahead"- mentality. Use natural and human resources for constructive solutions, not to create new problems which will delay the process more than absolutely necessary.
Global sustainability and balance is required within several fields, but perhaps most importantly concerning environment and economy. The two are closely related, so regulating one in the right direction will have positive affects on the other.
