My name is Enrique Valenzuela, and I am 19 years old. I was born in Buenos Aires, Argentina, and I moved to Miami when I was 15. When I got here I attended Coral Gables Senior High in my freshmen year, and in my sophomore year, I transferred to MAST Academy. After finishing high school I chose to stay in Miami and attend Miami Dade College Honors at the Padron Campus. In the future I see myself working in a bank as a Private Banker here in Miami, that is one of the reasons why I chose to stay here in Miami, because of my family and because I want to live here when I get older. The most important things in my life are my family and friends because without them I wouldn't be here in the first place. Because of my family, I moved to Miami, and because my friends told me about the Honors Program I heard about it. Another reason why I stayed in Miami is to continue playing Rugby with my friends. I have been playing Rugby since I was four years old. When the last game of my Senior year season ended, I couldn't see myself playing with different people, and my teammates went through the same. Now I am playing on a different team but with a lot of my old teammates.

This video talks about how gentrification is affecting Miami. But mostly about how the climate are shifting people from one place of the city to another, making poorer neighborhoods more expensive to live. This video made me understood the importance of fixing these problems in Miami, since I am living them. It is expected that on 2030 Miami Beach will suffer 45 floods a year. People from Liberty City and Little Haiti are getting knocked at their doors with offers to sell their homes. These people are offering a big amount of cash, and free rent is South Dade. So people who live in this poorer neighborhoods are being pressure to sell their homes and move to a lower elevation area. The difference that gentrification and climate gentrification have, is that gentrification only relates to housing. And that gentrification is harmful mostly for the fabric of established and cultural neighborhoods. When we talk about climate gentrification, we are also adding that people’s lives are at risk.

Electronics are ‘designed for dump.’ This is a key strategy that brands who make our electronics due. In fact, it is crucial for our unsustainable materials economy. This phrase means that today’s electronics are design to be thrown away quickly: hard to upgrade, impractical to repair, and easy to break.  In fact, in most cases, it is cheaper to buy something new that to repair it.

In the 60’s, Gordon Monroe, the giant brain and semiconductor pioneer, predicted that electronic designers could double processor speed every 18 months. This is called Moore’s Law. The only problem is that designers understood another thing from this law, which is that we have to throw our electronics every 18 months and buy a new one.

The truth is that 18 months is a small part in their entire cycle, causing not only pain in our wallets, also a global toxic emergency. Electronics starts in mines and factories. Most of our gadgets are made from more than 1000 different materials, which are shipped all around the world to assembly plants. In here, workers use loads of toxic chemicals to turn these materials into products. After assembly plants, these products are shipped to our hands for a year or so, then they start slowly deteriorating. After we decide to throw them out, they end up on one of the mountains of e-waste that we create each year.

Tourism is one of the fastests growing industries and an important source of foreign exchange and employment. The World Tourism Organization defines sustainable tourism as “tourism that takes full account of its current and future economic, social and environmental impacts, addressing the needs of visitors, the industry, the environment and host communities." The 2030 Agenda for Sustainable Development SDG target 8.9, aims to “by 2030, devise and implement policies to promote sustainable tourism that creates jobs and promotes local culture and products”. The importance of sustainable tourism is also highlighted in SDG target 12.b. which aims to “develop and implement tools to monitor sustainable development impacts for sustainable tourism that creates jobs and promotes local culture and products”.

Vermont has ne of the cleanest grids is the US. Two thirds of their energy comes from renewable energy sources such as solar, wind and hydroelectric plants. So why was a new project for a new solar energy plant denied? The problem that Vermont's powerline has, and why they cad to denied the projects, is that the powerlines are at maximum capacity. So a new plant would not be useful. So in order to have greener energy, we need to build more powerlines first.

In the other hand, Washington recieves most of their electricity from power plants, but for 2032 they want to be fully supported by renewable electricity. It is all part of a national goal, by 2050, President Biden, wants nearly half of the energy coming from solar plants.He also wants to reduce 50% of emmisions by 2030. Meaning that he wants to change from natural gas plants, to wind turbines. Or from coal plants to solar plants. He also wants people to switch from gas cars to electric cars, to start heating building with electric heat pumps, and for people to cook on electric stoves. Basically, we will need to use way more electricity than before. So if we do ot start to build more powerlines, all of that effort will not serve a purpose.

Encouraging Conservation or Adding to Exploitation?

Eco-tourism has emerged over the years, amd it is becoming one of the most important sectors of international tourism. Eco-tourism is responsible travel to natural areas that safeguards the integrity of the ecosystem and produces economic benefits for local communities to encourage conservation. Also this form of tourism is a creative way of marrying the goals of ecological conservation and economic development.

Eventhough some eco-tourism projects succed in promoting these two causes, there are others that are less succesful. Enviromental deterioration and inequitable development may in some cases actually be exacerbated by eco-tourism.To ensure that this completes its purpose, policymakers, promoters, and participants should make sure that all activities should have minimal enviromental impact.

Today, eco-tourism, forms the 7% of the tourism industry. Only in Asia, reporters ars showing a growth of 10 to 25% per year. That is why more developing countries are investing more and more money into their tropical beaches, ruins, etc.

One thing that caught my attention in this lecture is that even though wind energy, is the form of energy that uses the greatest amount of space to power a lightbulb, in comparison to other forms of energy, all of the space can be used for other stuff to.

According to researchers from John Hopkins, the general rule-of-thumb for wind farm spacing is that turbines are about 7 rotor diameters away from each other. So an 80-meter (262-foot) rotor would need to be 560 meters -- more than a third of a mile -- from adjacent turbines.

How can Sustainable Tourism be affected by Climate Change?

# data[].attributes.body
Climate change threatens all life on the planet, as well as the very destinations that tourism relies on. As the planet warms, rising sea levels, extreme weather, and increasing temperatures are impacting ecosystems and communities around the world. Beaches are shrinking, coral reefs are bleaching, and alpine resorts are left snowless and dry. If we want to save our planet and protect these special places, it’s up to each and every one of us to reduce our impact.

Many types of tourism are weather dependent and by extension, climate dependent. It is therefore very likely that climate change will affect your business area sooner or later. Climate change can reduce snow cover, increase and prolong heat waves or change the patterns of annual rainfall for example. Climate change is a relatively slow process, so probably in your region, the changes are not so obvious in the short run; but in that case, the effects may be strong in neighboring or competing areas and thereby still influence your business area.

Tourism is not just a victim of global warming – it also contributes to the problem. Tourism alone is responsible for 8% of the world’s carbon emissions. When we travel, carbon emissions are generated throughout our trips. While flying is the largest source of these emissions, other activities, such as using the AC in hotels or taking a boat ride, produce CO2 as well. Beyond these direct emissions, tourism development can also cause CO2 to be released by degrading ecosystems that act as carbon sinks.

I chose Goal #8 (Decent Work and Economic Growth), concentrating more on sustainable tourism. The reason why I wnt with this topic is because I am a business major and it made me intregue how can economic growth and climate change be correlated. This topic may be affected by climate change since any minor change that a place might suffer due to global warming can alter how many people visit a place.

Desalination of ocean water can be a potential solution to provide fresh water to dry areas of the world. The process of desalination involves removing salt and other minerals from seawater, making it safe for human consumption. This technology can help provide a reliable source of fresh water to areas facing severe water scarcity. Desalination plants can be set up in coastal regions where seawater is easily accessible. These plants use a variety of methods such as reverse osmosis, distillation, and electrodialysis to remove salt and other impurities from seawater. The resulting fresh water can then be transported to areas that are facing water scarcity through pipelines or tankers. While desalination technology can be expensive to set up and operate, its benefits can outweigh the costs in areas where access to fresh water is limited. Additionally, advancements in technology are making desalination more cost-effective and energy-efficient, making it a more viable solution for providing fresh water to dry areas of the world. Overall, desalination can be a potential solution to the growing problem of water scarcity, especially in areas where other sources of fresh water are scarce or unreliable. However, it is important to carefully consider the environmental impacts and sustainability of desalination plants before implementing them on a large scale.

For this assignment I chose Maria Tognini's padlet because I liked the topics that she discussed over the semester.The topic of her project, goal number 13, Climate Action, is an incredibly important issue in today's world. Climate change is caused by human activities and poses a significant risk to our planet's environment and ecosystems. Achieving this goal requires urgent and ambitious actions from governments, businesses, and individuals to reduce greenhouse gas emissions, increase resilience to climate impacts, and promote sustainable development. The success of goal number 13 is crucial for the future of our planet, and it requires collective efforts from all sectors of society. By focusing on this goal, you are contributing to the global efforts to combat climate change and protect our planet for future generations. I also enjoyed the display of her Padlet. It was full of colors and very organized, making it easy to find the topic she chose for the UN Sustainable Development Goals.

Before engaging in this course I did not know what to expect. Knowing that the classes were online and science being a subject I normally do not do well in, I was a little frustrated. I usually never liked science classes. I always though that I learnt thing that were irrelevant to my daily life and being a Finance major that I would never use or think of it again. I also never like the way the science classes I took in High School were taught. I felt that they were very repetitive and that it was more important to memorize the information that to actually learn it.

I had a great experience during my time in this course. It is the first time that I understood, and that I was interested to learn when taking a science class. We learned things that are currently happening (such as climate change), and the ways we have to solve this problem. I also enjoyed the way the professor taught this class. I liked that everything we did was during class time. That really helps with the stress that students have during the semester when homework gets accumulated.

Now that the semester has ended, I am glad that I choose to take this class. This is one of the classes that I enjoyed the most during my time at Miami Dade College, not only because I like how the class was taught and the subjects I learnt, also because it is the first time that I actually enjoyed a science class. I do not know where I am going to study next year, but I do know that I would like to still take some science classes wherever I am going.

In conclusion, I am very happy that I experience this class, and I hope that in the future I have Professors that teach their class the same way as you did!
