Transcript of Mesoamerica Biodiversity Hotspot

Biodiversity Hotspot
Our world today is deteriorating at a fast pace due to various strains we have place upon it. Humans have taken nature for granted and unfortunately, has been hurting some very important areas in the world; biodiversity hotspots. Biodiversity hotspots are “ the richest and most threatened reservoirs of plant and animal life on Earth”(conservation.org) . I personally think that everyone should know, care and be concerned about about the biodiversity hotspots that are scattered throughout the world. Humans have raised the rate of extinction by thousands, even tens of thousands and these hotspots are being greatly affected. Since they have an extraordinary amount of different species it is more likely that extinction will happen in hotspots. Do you care about Biodiversity hotspots? Why should we care about extinction? Extinction is a complete disappearance of a species, from the entire planet. Recently, extinction levels have gone up dramatically, mostly due to human greed. Everything is connected on the planet and if one thing disappears, other organisms suffer. They loose a food source or a predator which can mess the whole food chain up, which leads to us. ca Hotspot! The Mesoamerica hotspot is, most of Central America including subtropical and tropical ecosystems for Mexico to Pananma Canal. Mesoamerica also has many islands that are homes to endemic seabirds. Some contributors to making Mesoamerica a hotspots are its many forests, including dry forests, lowland moist forests and montane forests. Mesoamerica is the cross between North America and South America, so the different species from either continent paired up with each other and over time made completely new species. This is one of the reasons why Mesoamerica has such a high level of biodiversity. Reasons why it is a biodiversity hotspot are during the 1800s to 1900s many amounts there was a lot of deforestation to make crops. Deforestation still goes on today and there is a lot of industrial development and human over population. What is a Biodiversity hotspot? Biodiversity hotspots are areas in which large amounts of species live, and are threatened my human development. The combined are of hotspots make up 2.3% of the world and contain 50% of the worlds plant species and 42% of the " terrestrial vertebrate" species living in the 34 hotspots. Hotspots and the species living in them face extreme threats from natural and man made problems. Endemic Plants and Animals In Mesoamerica there are many species that are native to the area. Some of these species include the Lacandoniacease (plant) and the Mexican black howler Monkey. The Lacandoniacease is a flowering plant that is found in the mountain regions. It is known to be a blooming plant that blooms inside out. The howler monkey is named after its loud howl that can be heard from miles away. The monkey has a long tail and is a herbivore,who eats plants and flowers. The howler monkey is a not very threaten species, but in 30 years its population today should go down by 60%. What is the sixth extinction?? In the past there have been 5 mass extinction in the pass. A mass extinction is when a large amount of species become extinct in a short time span. The sixth extinction will be the sixth mass extinction planet earth will face. The extinction is going on right now, humans are the main cause of it. Every year between 17000 to 100000 species become extinct, and within the next 100 years 50% of the earths species will be extinct. This is mostly due to human impact, we have been breaking down the worlds resources and stealing them from the millions of species that have been living on the earth far longer than we have. Why is biodiversity decreasing? The main reasons for why biodiversity is decreasing in this region are loss of habitat, disease and climate change. A lot of deforestation is going on in Mesoamerica, Mesoamerica holds one of the highest deforestation rates in the world. Mesoamerica is a growing area that attracks many tourist, who take advantage of the land, and scare the animals off. Mesoamerica needs is expanding, currently industrial development is taking a toll on the environment. Also in Mesoamerica, the population is growing quickly, which means, the area needs places to expand and needs more jobs, crops create jobs. The soil is very poor in Mesoamerica, so once the crops don't grow in an area, they need to clear a new area for crops. If this happens often, land is taken up very quickly for crops, and re-growth of forests take a long period of time. Mesoameri What's being done to protect Mesoamerica?? Right now, 13% of Mesoamerica's land area is being protected. Many parks have not yet been approved, they are not protected until the government decides it's a good idea. They have not been approved because the people living around these parks need the things the park supplies for basic living. The Mesoamerican's have been trying to protect the main lands that are home to a lot of biodiversity, while at the same time sustaining life for humans. They are planning on doing this by environmentally-friendly forest plantation, reserves, and other ways of supporting agriculture. They try and find areas to protect, by looking at areas where many species face extinction in an area. Conservation International, Birdlife International and other organizations looking to conserve biodiversity have been trying to do this. Mesoamerica is also raising awareness (like other countries) for there environment by ecotourism. Ecotourism is a form of tourism where the tourist visit undisturbed, or natural areas are. Also zoo's and organazations have been raising awareness about all diversity hotspots and the deterioration of our environment.

Socio-Economic Conditions! Yay! Mesoamerica is very diverse in its animal biodiversity and also in its different type of people, cultures and races. Mesoamerica is a very old place, full of history and old myths and cultures. There are many countries that make up Mesoamerica, they are very warm countries and the people (for the most part) speak Spanish. Mesoamerican countries have difficulty with equality and deciding which countries get which resources. There is many different governments, and governing styles in Mesoamerica, so it is hard to say what all of the currency is like and exactly how they live. Mesoamerica gets a lot of tourism, so they are always trying to expand areas where they can accept tourists (to make money). There is over population of the human species and not the best living conditions (as Canadians are use to). What do I think? So what do I think we should do, to save Mesoamerica? I think that the different countries need to get together and have a meeting to discuss what can be done. If I were at that meeting, I would explain how I think the environment is the most important thing (to me) right now to worry about. I believe this because, without the environment and the animals we have today, humans would not survive very long. So what ever we do to the environment, will reflect upon how well we survive in the long run. I think that Mesoamerica needs to create agriculture that can sustain the population and keep the biodiversity. They can do this by creating gardens and such on the roof tops, taking only what they need to use. They can also try and place some species in an area that is already protected (as long as the species won't harm the other species).
