Hurwitz celebrated the event by taking our class to long Island sound, where she and her husband donned wetsuits and pulled a seine through the water. Having spent every summer of my young life playing around the beaches of Long Island, i thought I was familiar with its coastal denizens, but no: The creatures that came out of that net might have come from another planet, for all i knew. Fish, crabs, starfish, sea urchins, worms - they left me dumbfounded, and hooked on nature. And it wasn't just the field trip, it was the connection to a grassroots movement to protect the natural world, that captured my interest so powerfully. I was horrified to learn that this world I loved so much was being bathed in sewage, acid rain and toxic waste - and thrilled to hear about courageous people like rachel Carson, whose book silent Spring is often cited as launching the modern environmental. Love, devastation, salvation, presented in one short week of school. My little story certainly shows the power of one teacher, one event, one lesson, to shape a life. Ecology was a new word in 1970. By the time i went to college, long Island sound was dying, yet mom Environmental Science as a field of study barely existed.
If any paper of these factors were eliminated, there would be no life on Earth. Life could not survive on any other planet because while there are planets with some of these features, there is no planet except Earth with all of them. Hopefully we will never have to leave earth and find a new planet to inhabit because it would be very difficult to find one as perfect as Earth. These days, many people talk about environmental issues and the importance of taking some action, from recycling to land protection. If "every day is Earth day then what is the importance of that one calendar day, april 22? For me, the question has great personal significance. It was on the second Earth day, when I was in fifth grade (no, don't do the math! that I determined my life's work.
If Earth started to wobble it would effect our climate, but most life would still survive. However, life would not survive if Earth? S rotation sped. The moon as been slowing down the earth? S rotation ever since the moon has been our moon. If we lost it the earth would speed up again, and all life would vanish. For the reasons above, earth is a perfect place to live.

The presence of a surface on a planet is also important. If you tried to homeworks stand on Jupiter you would sink to the core of the planet. This would happen because jupiter is made of gas and has no surface, also jupiter? S gravity is more than twice as much as Earth? S, so it pulls things to the center of the planet.
Earth has a surface to stand on and enough gravity to hold thing on the surface. S moon helps support life. T live without. Our moon is so large that its gravity effects. Our moon helps keep Earth tilted on its axis. Our moon stops us from wobbling on our axis, like mars does.
Our atmosphere causes us to experience the greenhouse effect. The atmosphere holds in the heat from the sun, trapping it so we don? T get too cold. The speed of earth? S rotation is very important to sustaining life. If our planet were to spin as fast as a planet like jupiter, then important things would just fly off Earth.
Solid things would fly off because of Earth? S gravity, but the gas in our atmosphere would, and so might our water. If Earth rotated slower, then our temperatures would be effected. Earth is rotating at a perfect speed. Gravity is also very important for life. Gravity help hold things on a planet. If the earth had less gravity, like pluto, things would float away.

S perfect temperature is due to many things. Our distance from the sun determines how much of the sun? S heat we get. Our rotation of 24 hours ensures that no one side of Earth faces the sun for too long, unlike venus. Rotation is so slow that it is very hot on one side and very cold on the other because the side facing the sun faces it for so long that it can? T cool off, and the side facing away from the sun cools off for too long. Along with all of these things, the main factor that controls Earth? S temperature, is our atmosphere.
If there is no atmosphere, then there is no gas for plants and resume animals to breathe. Our atmosphere contains oxygen and carbon dioxide, along with many other gases. Animals breathe oxygen and plants breathe carbon dioxide. Venus also has an atmosphere, but it contains mostly sulfuric acid, plants and animals can? T live on Venus because the air is not breathable. S temperature is perfect for supporting life. S average temperature is 15C. Any other planet would either be too hot or too cold for life.
such as light to food. Earth is the only planet known to have a large amount of liquid water. Mars does have polar ice caps, but no liquid water. Life can not survive on a planet with no liquid water. Another unique feature of Earth is its atmosphere. A planet without an atmosphere, like mercury, could never have any life. Living things have to breathe.
Energy is needed in order for living things to grow. Our main source of energy on Earth comes from the sun. Plants use the light from the sun for photosynthesis, and plants source of food comes from photosynthesis. T need the sun to produce their own food they do eat plants, and all plants go through photosynthesis. Planets that are far from the sun, such as Pluto, tree can not use the sun? S light to produce food. Photosynthesis could never happen on Pluto.

Earth perfect Planet Essay, research Paper. What is required for a planet to be able to support life? This is a question that people have been trying to answer for many years. Earth is a very unique planet because it is the thank only one proven to support life. Living organisms need certain things in order to survive that are not found on any other planet. Some of these life supporting features include food, water, atmosphere, temperature, rotation, gravity, surface and a moon. First, living things need a source of food.
