A Quote by Elon Musk
There have only been about a half dozen genuinely important events in the four-billion-year saga of life on Earth: single-celled life, multicelled life, differentiation into plants and animals, movement of animals from water to land, and the advent of mammals and consciousness.

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth.
Nearly all of the major kinds of life, divisions of life, phyla of animals, occur in the sea. Only about half of them can make it to land or freshwater.
Our planet has been around only for four and a half billion years. Let's imagine a planet that has life on it such as life is on Earth and it's seven billion years old. Let's say that planet evolved intelligence. Well, that intelligence would be way more advanced than what we call intelligence here on Earth. How long has intelligence been around on Earth as we've come to define it?
The record of the rocks contains very little, other than bacteria and one-celled plants until, about a billion years ago, after some three billion years of invisible progress, a major breakthrough occurred. The first many-celled creatures appeared on earth.
It is a fact that plants also have life like animals. But animals are endowed with mind, and nervous systems too while the plants do not possess the same.
In the Gaia theory air, water, and soil are major components of one central organism, planet Earth. What we typically think of as life - the plants and animals that inhabit the earth - has evolved merely to regulate the chemistry of the biosphere. Humans are insignificant participants, far less important to the life cycle than termites. Even the imbalance that we have created by adding massive quantities of carbon dioxide to the atmosphere may be brought back to acceptable levels by other organisms functioning in their capacity to correct excesses.
In the last 680 million years of the four and a half billion that this planet has existed, life has been determined by two principal forces: the warmth and the diffused energy of the sunlight coming through our atmosphere, and water. Those are the primordial forces of life - sunlight and water.
The consumption of animals - whether you're wearing them or eating them - is extraordinarily damaging to the planet. There are over a billion animals killed a year for food, half of which don't even get eaten. And there's over 50 million animals killed just for fashion.
Earth as we know it came into being through its four great components: land, water, air, and life, all interacting in the light and energy of the sun. Although there was a sequence in the formation of the land sphere, the atmosphere, the water sphere, and the life sphere, these have so interacted with one another in the shaping of the Earth that we must somehow think of these as all present to one another and interacting from the beginning.
The coming week in The Hague may prove to be one of the most important in the three-and-a-half-billion year history of life on earth.
A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.
Raising crops to feed animals for human consumption requires a lot of land. It takes eight or nine cows a year to feed one average meat eater; each cow eats one acre of green plants, soybeans and corn per year; so it takes eight or nine acres of plants a year to feed one meat eater, compared with only half an acre to feed one vegetarian.
Scientists have been saying, for an awfully long time, that we're all interconnected. Scientists would use the word 'ecosystem' to express that idea. Obviously, people can't survive without air and water, and we rely on plants and animals for food, and plants and animals rely on us to preserve their habitats.
Why, then, does water-form the very basis of life in all life's various manifestations? Because water embraces everything is in and all through everything; because it rises above the distinctions between plants and animals and human beings; because it is a universal element shared by all; itself undetermined, yet determining; because, like the primal mother it is, it supplies the stuff of life to everything living.
Consider: Life arose on Earth close to four billion years ago. Four billion years of slithering, swimming, and soaring life forms. But only in the last 200 thousand years has a species arisen that can fathom the laws of nature and build hardware able to signal its presence.
If humans evolved in a tiny area of Africa, they only saw plants and animals within a 100-kilometre radius for a million years. When they began to migrate, there would have been different animals and plants - and potentially a lot of allergy issues.
