- 2441: Steps Towards An Ecosociety: Dealing With Air Pollution
- ... volcanoes or wind blown dust. Conversely, the majority of pollutants are the direct result of human interaction and misuse of our environment. An example of this is the loss of the whales, who for centuries lived in the St. Lawrence region of the Atlantic Ocean, but had to migrate due to the "...polluted water emptying out of the Great Lakes. They are said to be contaminated with toxic chemicals at concentration ...

History the history of fungi is not very clear because scientists have never realy wnt in great deepth , because fungi are not needed commericaly. the ancestors of fungi lived in shallow bodies of water about 600-800 million years ago.

- ... has an equal but opposite reaction). So the force of the earth pulling the apple to the ground is proportionally the same as the force the apple exerts back on the earth. Now Johannes Kepler lived some forty-five years before Isaac Newton. And he showed that the orbits of the planets in our solar system were elliptical. When the time of Newton came around he mathematically proved that, if Kepler ...
- 2444: Newton's First Law Of Motion
- Sir Isaac Newton was in my mind one of the greatest people who ever lived. He was born in 1642 and died in 1727. He formulated three laws of motion that help explain some very important principles of physics. Some of Newton's laws could only be proved under certain ...
- 2445: Evolution From A Molecular Perspective
- ... day chimpanzees, for example, is the fact that they must have shared a common ancestor. The "common ancestor" theory, as I have chosen to name it, states that all life living, or ever to have lived on this planet can be traced back to a single, common ancestor. At some point in time, between 3.5 and 4.1 billion years ago, a certain grouping of chemicals came together at just ...
- 2446: All About Ants (almost)
- ... and can lay millions of eggs in that time (Ant Colony Å’89). Male ants are winged as well, their sole purpose is to mate with the queens. For this reason they are the shortest lived ants in the colony. Hatching in the spring, they mate in the summer and upon completion of this task promptly die. As in all Hymenoptera, they are formed from non-fertilized eggs (Social Insects Å ...
- 2447: Neptune
- ... the Great Dark Spot. The pinwheel shape of both the dark boundary and the white cirrus suggests that the storm system rotates counterclockwise. Periodic small scale patterns in the white cloud, possibly waves, are short lived and do not persist from one Neptunian rotation to the next. (Courtesy NASA/JPL) Until the Voyager 2 encounter in 1989, the rings surrounding Neptune were thought to be arcs. We now know that the ...
- 2448: Galileo
- ... many people to be hostile to the theories but Darwin still remained in better standing with the church than Galileo ever was. The main reason for this is the fact that in the time Darwin lived there were more people that were educated in the ways of science which was far more progressed than in the days of Galileo. These new scientific people were more open to ideas than the more ...
- 2449: Effects Of Dam Building
- ... of the largest problems with this dam, is that it would be built on a region that meant a lot to 10 500 Cree and 7 000 Inuit. Lands that their ancestors have hunted and lived on for more than 5 000 years will be flooded along with 90% of their trapping lines.6 If this happened these people must resettle, find a new way of life and face the destruction ...
- 2450: Human Evolution
- ... of their teeth, jaws, and brain size, however, they differ sufficiently among themselves to warrant division into four species: A. afarensis, A. africanus, A. robustus, and A. boisei. The earliest australopithecine is A. afarensis, which lived in eastern Africa between 3 and 4 million years ago. Found in the Afar region of Ethiopia and in Tanzania, A. afarensis had a brain size a little larger than those of chimpanzees (about 400 ...
