Voluntourism: An Opportunity Too Good to be True

A Speech to the Student Body of Evergreen High

[1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference.

[2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help."

[3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved.

[4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels).

[5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour.

[6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.

Identify the two strategies the speaker uses to develop the point that people who voluntour often have selfish motivations.

How does surface tension work with water molecules?

Answers

Answer:

Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. At the surface, though, the outmost layer of molecules, has fewer molecules to cling to, therefore compensates by establishing stronger bonds with its neighbors, this leading to the formation of the surface tension.

Surface Tension of Water . The surface tension of water is 72 dynes/cm at 25°C . It would take a force of 72 dynes to break a surface film of water 1 cm long. The surface tension of water decreases significantly with temperature as shown in the graph. The surface tension arises from the polar nature of the water molecule.

- The genome of P. larselli is over 2x the size of p-richmondi, but they have approximately the same number of genes. What accounts for the difference in genome size

Answers

Plethadon is a genus inclusive of the salamander family.

As a genus,it has a high rate of inter species genetic variability, The C value which is a measure of genetic variation in species is very high especially in this genus.

Low rate of mutation, climatic niche and low rate of DNA loss etc are some of the various factors.

p.larselli and p.richamondi has a difference in genome size and this difference can be attributed to the presence of more DNA segments

that are none coding in larselli compares to that of richamondi.

The DNA fragments that does not code for protein are the non coding sequence but they have some other revolutionary and evolutionary functions.

Some of these sites that doesn't code can be small repeating sequence, microsatellites and variable number tandem repeats etc and these shows high chances that richamondi have lost some of these sequence that are non coding from it's chromosome as part of a genetic or epigenetic changes during the course of evolution or there might be also a high rate of mutations among them leading them to loose some DNA fragments.

Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, aorta


Superior vena cava, left atrium, left AV valve, left ventricle, pulmonary semilunar valve, left pulmonary artery


Superior vena cava, right atrium, right AV valve, right ventricle, pulmonary semilunar valve, left pulmonary artery

Answers

Answer:

Explanation:

Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium. From the left atrium blood flows into the left ventricle.

The correct option that describes the flow of oxygenated blood through the heart is B, Pulmonary veins, left atrium, left AV valve, left ventricle, aortic semilunar valve, and aorta.

The left atrium is where oxygenated blood enters the heart after traveling from the lungs to the heart via the pulmonary veins. The left AV (atrioventricular) valve, also referred to as the mitral valve, allows blood to pass from the left atrium into the left ventricle.

The aortic semilunar valve, the body's primary artery that carries oxygenated blood to all the organs and tissues, is opened as the left ventricle contracts, pumping blood out into the body.
