Species are disappearing at an accelerating rate through human action, primarily habitat destruction but also pollution and the
introduction of exotic species into residual natural environments. I have said that a fifth or more of the species of plants and animals could vanish or be doomed to early extinction by the year 2020 unless better efforts are made to save them. As the last forests are felled in forest strongholds like the Philippines and Ecuador, the decline of species will accelerate even more. In the world as a whole, extinction rates are already hundreds or thousands of times higher than before the coming of man. They cannot be balanced by new evolution in any period of time that has meaning for the human race. What message does the author convey in this excerpt?
The author is saying that because of humans and the ways they are impacting earth is causing irreparable changes like causing animals to go extinct, etc.
Humans need to take action to end further destruction of the natural environment.

This excerpt from "How the Internet and Other Technologies Came About," explains that virtual reality, which is now used as a new type of video games, was first used to create tanks and submarine simulations.
This supports the idea that the technology now used in videogames resulted from an effort to solve national security problems.
