A Quote by Seth Shostak
One of the jovian moons, Europa, is coated with twice as much liquid water as is sloshing around our planet.

Our best shot at finding life in our solar system might be to look at the moons of Jupiter and Saturn. Mars, increasingly, looks like a dead planet. But the oceans beneath the ice cover of the moons of Jupiter and Saturn may actually have more liquid water than the oceans of Earth.
Mars still remains the astrobiology community's number one choice for 'nearest rock with life,' but there are many researchers who argue that the moons of Jupiter are better bets. In particular, Europa, Ganymede, and Callisto are all thought to hide vast oceans of liquid water beneath their icy, outer skins.
No one predicted Mercury would be a planetary core with the mantle stripped off. No one predicted volcanoes on the Jovian moons, or oceans on the inside of them. I can tell you, for every single planet, huge 'we never guessed that' things.
Why must women stay quietly? Why must we be little moons, each of us stuck in our little orbit, revolving around a planet that is some man? Why can't we be other planets? Why must we be moons?
In 2000, twice as much water was used throughout the world as in 1960. By 2050, half of the planet's projected 8.9 billion people will live in countries that are chronically short of water.
Somebody who eats twice as much factory-farmed products as he or she needs to is clearly doing twice as much damage to the planet. From a utilitarian point of view, that's twice as bad.
The perception of juiciness involves a complex jumble of things, including how quickly juices are squeezed out of meat fibers by our teeth, how much saliva we produce, and the ratio of liquid fat to water-based liquid.
Water has always been something that I care deeply about, and I'm very aware of its limits on this planet. If we don't change our behavior around water, water will become as valuable as oil. That is a given. When people don't understand that, I'm surprised.
As far as Europa goes, Europa very likely has an ocean under its surface. In that regard, Europa and Enceladus are on equal par. But on Europa, the ocean is at least several kilometers under the surface, and the moon is bathed in an intense radiation field.
The environment is everything that makes up our surroundings and affects our ability to live on the earth - the air we breathe, the water that covers most of the earth's surface, the plants and animals around us, the overall condition of our planet, and much more.
Water is everywhere and in all living things; we cannot be seperated from water. No water, no life. Period. Water comes in many forms - liquid, vapor, ice, snow, fog, rain, hail. But no matter the form, it's still water.
I'm interested in anything that deals with our planet, in our planet, outside our planet, the universe, universes, galactic, dimensional, subterranean. That's deep stuff that everybody needs to focus on: What is your niche on this planet? Why are we here? Why are there roaches and water-bugs and all that type of stuff?
In days gone by, scientists would speak solemnly about our solar system's 'habitable zone' - a theoretical region extending from Venus to Mars, but perhaps not encompassing either, where a planet would be the right temperature to have liquid water on its surface.
My brain still recoils at memories of the tofu stir-fries in my college co-op. A student 'cook' made them in a wok the size of a prosperous Martian's flying saucer, and, man, were they bad - steamy, crumbled bits of tofu and limp greens sloshing around in a warm bath of liquid aminos. I couldn't eat tofu for decades.
The environment is everything that makes up our surroundings and affects our ability to live on the earth - the air we breathe, the water that covers most of the earth's surface, the plants and animals around us, the overall condition of our planet, and much more. Protecting the environment is really important to everyone's welfare - that of our children, as well as that of the future generations.
If you want to feed the planet and keep the forests we have, you need to be able to grow roughly twice as much food per acre around the world. How do you do that? New technology.
