Galapagos Islands?

Question

how does human invasion effect the wildlife on the GAlapagos Islands?

Answer 1

Sailors came to the Galapagos Islands and brought their cats with them. These cats learned how to be wild instead of housepets. They then began to eat all the tiny creatures around and half of them are probably extinct. Try looking it up more online. Type in "Galapagos Islands".

While this unforgiving and uncontrollable force of nature has had a destructive impact on the Galapagos, many of the environmental issues facing the Galapagos originate from a potentially controllable source --human beings. The presence of people in the Islands has two sources: migration from the mainland and tourism.

Also known as James and San Salvador the central location and numerous landing sites make Santiago a part of almost every Galapagos itinerary. A favorite island for pirates and whalers, Santiago has a long human history as well as some outstanding opportunities for wildlife viewing. Highlights of a visit include the Fur Seal grotto, Pink Flamingo lagoon as well as the chance to see Galapagos Hawks and Vermilion Fly Catchers.

Although the Galapagos remained untouched by man until fairly recently, the effects of his short presence in the islands have been disastrous upon their fragile ecosystem. First the pirates of the seventeenth and eighteenth centuries, and then the whalers and sealers of the nineteenth, carried off hundreds of thousands of giant tortoises to store as a source of fresh meat aboard ship. At the same time they introduced various types of mammals that established themselves on a number of islands. Some, such as rats, disembarked involuntarily from the sailing ships, while others, like goats, were intentionally set free in order to provide these early sailors with meat

For many Ecuadorians the Galapagos Islands is a modern day El Dorado offering economic growth, plenty of work opportunities, and 50% higher salaries than on the mainland. In a country of 40% unemployment, the draw of the islands is hard to resist. The population growth in the settlement areas is astronomical and land prices have soared. The government's attempts to pass laws to curtail the influx of settlers have all met with opposition from the general populous who feel they too have the right to take advantage of this bonanza.

Tourism is not without its problems. With more than 60,000 people a year visiting the island the increase in waste disposal the shear number of people and the pressures it creates on the islands. Many visitor sites with delicate conditions including lava formations that restrict the size of the boats allowed to visit them in order to minimize the damage.
