Answer
A weed can be defined in several ways.

There appear to be three dominant perspectives on weeds: agricultural-ranching, suburban, and ecological. The agricultural perspective considers any plant a weed if it competes with crops for the available nutrients and moisture in a field. Such plants can lower crop yield or cause crop failure. Closely related to this is the ranching perspective, which replaces the agricultural perspective in those areas where rearing of livestock is dominant. The ranching perspective considers any plant a weed if it presents a threat to livestock or reduces the quality of forage that is otherwise available. As a result, livestock gain weight less readily, or they may become ill or injured, sometimes fatally by the uneconomic properties of weedy plants.

The suburban perspective considers any plant a weed if it invades the lawns and gardens of suburban homeowners and other managed landscapes of mainstream society, which includes the lawns and gardens of banks, schools, churches, malls, government buildings, industrial parks, etc. In the context of this perspective, plants are valueless weeds unless they have been made available through the mass market.

The ecological perspective considers any plant a weed if it is a pioneer species that thrives in a degraded habitat with a history of disturbance through human agency. Such weeds may be native or introduced. There are also superweeds that have the capacity to invade high quality natural areas. Superweeds are usually introduced plants with few natural enemies in the area of invasion. By forming dense colonies, they displace native plants and reduce biodiversity. The more ordinary kinds of weeds are not considered a significant threat to the natural environment because they tend to disappear after artificial disturbances have been removed, while superweeds are dreaded by nearly all ecologists.

Because many plants are native is one area and a 'weed' in another, it is difficult to come up with firm numbers on weeds. For invasive organisms, one place to looks is the Global Invasive Species Database (GISD) - see below. Also, the Weed Science Society of America publishes a book on "1,000 Weeds of North America" - of course these represent only a small sample of the weeds of the entire world.

Of course, if you really were asking about cannabis (weed vrs weeds): There are two main varieties of Cannabis found in the world: Cannabis sativa and Cannabis indica. Cannabis sativa (the ganja variety) is a large âtree likeâ plant with light green foliage. It is indigenous to Mexico, Columbia, Thailand, India, and Africa.

Cannabis Indica (the hashish variety) is a smaller plant with wide, dark green foliage. It matures earlier and produces more potent, fatter, resinous flowers. Cannabis indica is indigenous to the high northern mountain ranges of the Afghani Hindu Kush, Pakistani Kara Korams, Russian Pamirs and Indian Himalayas.

There are many strains of each of the Cannabis varieties. I suggest the three volumes of "The Big Book of Buds: Marijuana Varieties from the World's Great Seed Breeders" by Ed Rosenthal as the current best reference.

Answer
Interesting Geography:

Alaska
More than half of the coastline of the entire United States is in Alaska .

Amazon
The Amazon rainforest produces more than 20% the world's oxygen supply. The Amazon River pushes so much water into the Atlantic Ocean that, more than one hundred miles at sea off the mouth of the river, one can dip fresh water out of the ocean. The volume of water in the Amazon river is greater than the next eight largest rivers in the world combined and three times the flow of all rivers in the United States .

Antarctica
Antarctica is the only land on our planet that is not owned by any country. Ninety percent of the world's ice covers Antarctica . This ice also represents seventy percent of all the fresh water in the world. As strange as it sounds, however, Antarctica is essentially a desert. The average yearly total precipitation is about two inches. Although covered with ice (all but 0.4% of it, i.e.), Antarctica is the driest place on the planet, with an absolute humidity lower than the Gobi desert.

Canada
Canada has more lakes than the rest of the world combined. Canada is an Indian word meaning " Big Village ."

Chicago
Next to Warsaw , Chicago has the largest Polish population in the world.

Detroit
Woodward Avenue in Detroit, Michigan, carries the designation M-1, named so because it was the first paved road anywhere.

Damascus, Syria
Damascus, Syria, was flourishing a couple of thousand years before Rome was founded in 753 BC, making it the oldest continuously inhabited city in existence.

Istanbul, Turkey
Istanbul, Turkey, is the only city in the world located on two continents.

Los Angeles
Los Angeles's full name is El Pueblo de Nuestra Senora la Reina de los Angeles de Porciuncula --and can be abbreviated to 3.63% of its size: L.A.

New York City
There are more Irish in New York City than in Dublin, Ireland; more Italians in New York City than in Rome, Italy; and more Jews in New York City than in Tel Aviv, Israel.

Ohio
There are no natural lakes in the state of Ohio , every one is manmade.

Rome
The first city to reach a population of 1 million people was Rome , Italy in 133 B.C. There is a city called Rome on every continent.

Siberia
Siberia contains more than 25% of the world's forests.

S.M.O.M.
The actual smallest sovereign entity in the world is the Sovereign Military Order of Malta (S.M.O.M.). It is located in the city of Rome, Italy, has an area of two tennis courts, and as of 2001 has a population of 80, 20 less people than the Vatican. It is a sovereign entity under international law, just as the Vatican is.

Sahara Desert
In the Sahara Desert , there is a town named Tidikelt, which did not receive a drop of rain for ten years. Technically though, the driest place on Earth is in the valleys of the Antarctic near Ross Island . There has been no rainfall there for two million years.

Spain
Spain literally means 'the land of rabbits.'

Roads
Chances that a road is unpaved in the U.S.A. : 1%, in Canada : 75%.

Texas
The deepest hole ever made in the world is in Texas . It is as deep as 20 empire state buildings but only 3 inches wide.

United States
The Eisenhower interstate system requires that one-mile in every five must be straight. These straight sections are usable as airstrips in times of war or other emergencies.

Waterfalls
The water of Angel Falls (the World's highest) in Venezuela drops 3,212 feet (979 meters). They are 15 times higher than Niagara Falls .
