When one tugs at a single thing in nature, he finds it attached to the rest of the world
John Muir
Earth day is the one day of the year that the whole world pauses to think about the environment. But one day a year isn't enough, because protecting and preserving nature should be a lifelong guiding principle, and not of effort that is expended in just one single day. And because nature is so interconnected, it cannot be dependent just on actions that taken in a few locations. It should be the ethos for everyone.
For example, the California poppy is an ubiquitous flower, found in different parts of the west coast of North America in multiple different climates. A single flower from a single shoot, fragile though it may be, represents significant effort by the plant to propagate itself for future generations. And its success is dependent on so many interconnected factors: location, short-term weather and long-term climate trends, wildlife, pollinators and lastly, humanity. On a global scale, the human species has such a high impact and influence on nature, that the burden of preserving the delicate balance also falls on to us.
After all, the Earth is what we all have in common
