Is there any more stuff I need for the galapagos islands?
Galapagos islands are a group of 24 isolated islands to the West of ecuador who own them. These provide great examples of how increased population and introduction of exotic species can have devestating effects on other species and put them at risk of extinction. The islands are so isolated so some islandsa have species particular to them and these provide great examples of speciation.
There are many threats to the species of Galapagos. One of these threats is increased human population increasing the need for water, sanitation and energy. For example in 1980 the population was 5,000 with around 4,000 tourists however in 2005 the population had risen to 28,000 with a massive 100,000 tourists. Also, there is the problem of habitat destruction I.e. The clearing of land for agriculture. Furthermore, there is the problem of over exploitation for resources such as overfishing and killing of tortoises for food. Furthermore, there is also the problem of introduction of non native species to the islands such as goats and cats which may interrupt fragile food webs. Also, this can lead to increased competition and the wiping out of native species I.e. Red quinine tree. There have been many measures taken over the year. For example in 1934 islands set up a wildlife sanctuary. In 1959 they created designated national park. Then in 1986, they created a Marine Reserve created. Also, a Quarantine system has been introduced to prevent exotic species getting onto islands. More than this, they have also limited the amount of places tourists can visit. Also. They have stopped fishing in some areas and have gone to the extent of culling goats and pigs to prevent the erosion of soil.
