When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison.

Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

Problem: After the 1998 embassy bombings, the U.S. government tried to develop a clearer picture of Bin Laden's finances. A U.S. interagency group traveled to Saudi Arabia twice, in 1999 and 2000, to get information from the Saudis about their understanding of those finances. The group eventually concluded that the oft-repeated assertion that Bin Laden was funding al Qaeda from his personal fortune was in fact not true. The officials developed a new theory: al Qaeda was getting its money elsewhere, and the United States needed to focus on other sources of funding, such as charities, wealthy donors, and financial facilitators. Ultimately, although the intelligence community devoted more resources to the issue and produced somewhat more intelligence, it remained difficult to distinguish al Qaeda's financial transactions among the vast sums moving in the international financial system. The CIA was not able to find or disrupt al Qaeda's money flows. The NSC staff thought that one possible solution to these weaknesses in the intelligence community was to create an all-source terrorist-financing intelligence analysis center. Clarke pushed for the funding of such a center at Treasury, but neither Treasury nor the CIA was willing to commit the resources. Within the United States, various FBI field offices gathered intelligence on organizations suspected of raising funds for al Qaeda or other terrorist groups. By 9/11, FBI agents understood that there were extremist organizations operating within the United States supporting a global jihadist movement and with substantial connections to al Qaeda. The FBI operated a web of informants, conducted electronic surveillance, and had opened significant investigations in a number of field offices, including New York, Chicago, Detroit, San Diego, and Minneapolis. On a national level, however, the FBI never used the information to gain a systematic or strategic understanding of the nature and extent of al Qaeda fundraising. Treasury regulators, as well as U.S. financial institutions, were generally focused on finding and deterring or disrupting the vast flows of U.S. currency generated by drug trafficking and high-level international fraud. Large-scale scandals, such as the use of the Bank of New York by Russian money launderers to move millions of dollars out of Russia, captured the attention of the Department of the Treasury and of Congress. Before 9/11, Treasury did not consider terrorist financing important enough to mention in its national strategy for money laundering.

Question: "Why was FBI conducting electronic surveillance and used informants in major US cities?"

In March 2001, Rice asked the CIA to prepare a new series of authorities for covert action in Afghanistan. Rice's recollection was that the idea had come from Clarke and the NSC senior director for intelligence, Mary McCarthy, and had been linked to the proposal for aid to the Northern Alliance and the Uzbeks. Rice described the draft document as providing for "consolidation plus," superseding the various Clinton administration documents. In fact, the CIA drafted two documents. One was a finding that did concern aid to opponents of the Taliban regime; the other was a draft Memorandum of Notification, which included more open-ended language authorizing possible lethal action in a variety of situations. Tenet delivered both to Hadley on March 28. The CIA's notes for Tenet advised him that "in response to the NSC request for drafts that will help the policymakers review their options, each of the documents has been crafted to provide the Agency with the broadest possible discretion permissible under the law." At the meeting, Tenet argued for deciding on a policy before deciding on the legal authorities to implement it. Hadley accepted this argument, and the draft MON was put on hold. As the policy review moved forward, the planned covert action program for Afghanistan was included in the draft presidential directive, as part of an "Annex A" on intelligence activities to "eliminate the al Qaeda threat." The main debate during the summer of 2001 concentrated on the one new mechanism for a lethal attack on Bin Laden-an armed version of the Predator drone. In the first months of the new administration, questions concerning the Predator became more and more a central focus of dispute. Clarke favored resuming Predator flights over Afghanistan as soon as weather permitted, hoping that they still might provide the elusive "actionable intelligence" to target Bin Laden with cruise missiles. Learning that the Air Force was thinking of equipping Predators with warheads, Clarke became even more enthusiastic about redeployment. The CTC chief, Cofer Black, argued against deploying the Predator for reconnaissance purposes. He recalled that theTaliban had spotted a Predator in the fall of 2000 and scrambled their MiG fighters. Black wanted to wait until the armed version was ready. "I do not believe the possible recon value outweighs the risk of possible program termination when the stakes are raised by the Taliban parading a charred Predator in front of CNN," he wrote.
