= How can sustainable development be achieved? What evidence of it did you find in Monteverde? = Sustainable development is using resource but without exploiting them. Sustainable development can be achieved when humans are in balance with nature. Sustainable development is taking from nature but giving the exact same amount back. The indigenous people are a good example of sustainable development, in Monteverde the pigs' fecal matter is used to create methane gas, this gas is used to cook. Also, in the UGA Campus the food that is going to be thrown away is given to the pigs instead, this way no food is wasted and the pigs are fed. The quakers a religious society that founded Monteverde, is an example of sustainable development. They produce their own food, and live with the things they need, no more. Ecotourism, is one of the main sources of income toc for Monteverde's economy, ecotourism consists in using nature to attract tourists. Monteverde uses it's rain forests and diversity to attract tourists from around the world. Ecotourism can be an example of sustainable development for example in the UGA Campus they used its beautiful surroundings to attract tourists. Also, they try to build a biological corridor so their banner specie, the bell bird, can reproduce and mate. With their campus they do not interfere in the harmony of nature. =media type="youtube" key="ZTeeXZkQVaE" height="315" width="560"= = How does development impact biodiversity in Monteverde? = As Costa Rica develops and it's beaches and cities become larger in terms of urbanization little natural reserves are left. However, Monteverde is one of the few places in Costa Rica that uses ecotourism, and it's biodiversity as an attraction for the tourists. Some species in Monteverde have disappeared due to urbanization, and many are endangered. So many organizations in Monteverde are trying to create biological corridors animals do not lose their habitat. Species do not live only in Monteverde and for example the the Three-wattled Bellbird, depends on nearby places like Nicoya, which is very urbanized. The Bellbird is used as a banner specie to create biological corridors, and this way help other animals. The development around Monteverde has helped Monteverde to become more environmentally friendly and it has used its ecotourism to produce more income. The UGA is trying to create more biological corridors around Monteverde and its nearby regions, this way many species can be saved from extinction. Development impacts Monteverde negatively because even though they have many acres of natural wildlife, its species need more space than that because if not then they may start inbreeding and eventually the specie will get extinct.

= What are the most critical factors causing ecosystem changes? = Nature changes everyday, some changes may happen because it is nature's way of doing things or because it was caused by a human action. However, there are changes that are very drastic and that because of these, many species have gotten extinct. Hunting, global warming, construction, and irresponsible use of land are many of the reasons ecosystem changes. With the increasing population, more and more forests are cut down to make space for new houses, buildings and cities. Illegal hunting and global warming are contributors to the ecosystem changes that occur from day to day. Also, climate changes which may be linked with global warming affects many ecosystems. For example, the sex of the turtles is determined due to the temperature, so if it is too hot or too cold only one type will be born. Producing catastrophic changes to the population. Here you can learn how is biodiversity and climate change related EcoMeasures.

= What options exist to manage ecosystems sustainably? = Ecosystems need to be managed sustainably because if not one day, there would be not be any left. And from ecosystems we get from medicine to food, to resources that are basic for any life form like air or water. Humans have destroyed ecosystems to make land for farming, or for building their houses or even for making a parking lot. However, when we destroy this ecosystems animals are affected, trees are affected and even us are affected. But we can manage ecosystems so we can preserve nature but also live our lives without making any great change. To manage ecosystems sustainably changes must be made starting from raising awareness throughout the population of how much we actually need them. Construction policies must be changed so the ecosystems are not affected, and new green technology should be actually put into work. You can learn more about ecosystems and the services they provide to us in here, EcoWorkshop. Also with this modern technology like GPS we can record were species are most frequently found, and where they are almost no species living there so there people could build where species do not habit.

= Why are insects worth conserving? = Insects are basically one of the organisms that make this world work, they are at the bottomof the food chain but this doesn't me they aren't important. In fact, by been at the bottom of the food chain they make them on of the most important organisms worth conserving. For example, if a population of insects dies then its predator would die, then the predator's predator will die and eventually this chain effect will reach us. Furthermore, insects constitute to one of the largest groups of animals in the animal kingdom. Insects pollinate and decompose things that feeds the soil and soil is one of the main resources used by humans, for example to plant our wheat, corn, or fruits, or to feed our cattle. Insects and man have been friends for a long time if we do not conserve them many would die, like the silk worm that has been domesticated for its fabric and probably if it is released into the wild it would die.

= = = = = = = = = How is international trade related to endangered species of wild fauna and flora? =

media type="youtube" key="BkwoxfSEJYE" height="346" width="462" Many times the endangered species are the ones with the most trade. Mainly because being endangered makes them exotic and the trade is so high that the demand is very high so species are traded and they can become extinct. For example, finning, sharks are believed to have magical powers because many times they do not get sick or they do not get cancer. So in the eastern part of the world finning has become an extremely popular fashion were millions of sharks are killed every day for their fins. So these has decreased the shark populations by about a 90%. International trade is the exchange of goods, outside a country, however animals shouldn't be looked as goods. Because goods many times are farmed or have special places where there are millions of them. But animals are getting extinct by hundreds each day, and there are not as many animals out there to have everybody trade them. Also, the problem is that when international trade occurs animals are not move for them to live at another place, they are killed for their skin or fur, or even for some nonsense as their fins and horns. The rhinos are prosecuted every day for their horns because like fins they are believed to have magical powers when they do not have. Extreme measure to save rhinos from poachers are cutting their horns as soon as they are born so poachers do not look for them. But this should not be a way to deal with poachers hard punishments should be put on hunters that seek rhinos. Also, many times if the animal is not kill during the trade they are moved to another location, then they enter as an introduced specie and local animals will die because they have a new predator and the new specie will become a pest. media type="youtube" key="2j9g4gh5LrE" height="315" width="560"
