Changes effected by a single person, relayed by high-end communication devices, are immediately accessible to the whole, impacting the whole, radiating to organizations which can amplify their original effect. As we adjust our ways - then reflected by hundreds of millions of our peers - we become able to alter the boundaries of nature and define them. And this freedom implies responsibility.
Clearly, fitness, nowadays, is achieved by finding ways to produce resources in harmony with the existing environment. Because if repeated and echoed by our peers, only actions conducted in harmony with the environment will STAY safe and remain viable as they become global processes. If ten million people act to recycle one plastic bottle each - ten million plastic bottles will have been spared. If the same persons spare ten kilowatts a day...
At a time in our history when our maturity allows us to create and modify features of our environment, we MUST learn to do so responsibly, in order to reap the benefits of this freedom - and avoid becoming victims of the consequences of bad environmental policies and practices.
