How many trees are there on earth?
Really, Trees, both leafy and otherwise, reflect sunshine in very particular patterns, making it possible for satellites to map and computers to count strips of land where trees are. Biologists can then sample those places - forests, suburbs, city parks, even city streets - assume a tree density, multiply by acre or hectare, and calculate that. In 2005, there were 400,246,300,201 (more or less) trees on our globe. (That's over 400 billion, for those of you who have trouble working through the commas.) ***EDIT*** - Strange, 400 billion trees only averages out to 60 trees to every 1 human being? Most scientist agree that the data needed to complete the complex mathematics required to accurately approximate the number of trees on the planet Earth simply does not exist. The truth is, we have no idea. Estimates have ranged from anywhere between 1 to 10 trillion trees currently inhabit the surface of the Earth (a considerably noticeable gap can easily be observed between these two figures lol). The number you quoted above (400,246,300,201) was a study funded by an extremely liberal organization which went on to claim (outrageously) that over 50% of the trees on the planet Earth have been harvested/destroyed by human beings. If this were true, the entire human population would have been swept away in an enormous fresh water flood and any remaining survivors would eventually die from starvation, soil degradation/poisoning and/or extreme atmospheric deterioration. I'll let the rest of you decide what you CHOOSE to believe.

Thanks for the feedback!
The earliest flora that we would recognize and call "trees" were early conifers that evolved during the Middle Permian epoch, about 275 million years ago. There were very larg…e "tree-like" plants prior to that, but they were more akin to gigantic ferns.
Absorb carbon dioxide,produce oxygen, are the habitat of millions of species of animals, keep water tables from rising and causing salinity,stabilize soils to prevent landslid…es and flooding. Trees provide a much needed shade in the summers hot sun.
There is no specific number to make a grove, it can be five to infinity.
About 360 million years. (After the Cambrian period 550 million years ago, or "Cambrian explosion", as it is known, when most animal life began on this planet, plant life bega…n to appear. The first plants, in the ocean, appeared 460 million years ago, and the first trees about 100 million years after that.) Answer 2 : Trees must not be confused with plant ! Word trees is reserved for tree ferns , gymnosperms and angiosperms , which appeared in late Paleozoic Era nearly 400 million years ago .
They give oxygen and oxygen brings life
Trees create a balance with animals, as they take in carbon dioxide and release oxygen. In actual fact, though, the oceans could be seen as the lungs of the earth, because ph…ytoplankton (plankton types that are plants not animals) produce as much as 70% of the oxygen we need through this same process. This is why it is so important to protect ocean ecosystems...
it depends on what type of trees. oaks and maples are very common in theUSA. but there are certain types of trees that are becoming extinct for example the red oak tree is now… almost extinct. if your wondering if global warming had anything to do with it the answer is not really. you see people blame only global warming for cutting down trees, but there are a lot of other types of wood company's cutting down and selling trees. and global warming is planting trees too. and just to answer your question, no the earth is not running out of trees.
Well, first off, it's not gonna happen, so don't worry about that. Trees, or more accurately, the photosynthesis they carry out, convert carbon dioxide to oxygen. It migh…t sound odd, but yes, trees and plants breathe IN what YOU breathe OUT. Every time you exhale, you give a tree or a plant the breathe of life. Trees are not the only providers of oxygen, but they certainly help. River also provide oxygen. They depend on us. We depend on them.Luckily, they can be renewed (planted from seeds) and grow almost anywhere. There are more trees in North America (AMAZON) now than there were in 1492.
Hundreds of nurseries in the United States grow over 1.5 billion trees annually, which reforests nearly three million acres. This number represents over six trees planted for …every U.S. citizen. The United States Forest Service prepares a report periodically on tree planting, timber stand improvement, and nursery production activities across all ownerships of forest land in the United States. I want to review highlights published in their most recent summary. according to http://forestry.about.com/cs/treeplanting/f/howmany_trees.htm
trees are important to the earth because without trees we wouldn't get any air and we would die
Because the trees take up carbon and increase cloudiness, which helps to cool the earth.
The first plants to develop a woody core and begin looking like tress were ferns - as early as the Middle Devonian (around 388 million years ago) one species, Wattieza, ha…d already reached heights of 8 m and a tree-like habit. Archaeopteris (an ancestor to gymnosperms like conifers) came a bit later and produced the first true wood. The first trees we would recognize where the Conifers which appear in the fossil record around the Pennsylvanian (323.2 million years ago to 298.9 million years ago) .
