Cloning?


Today, I will interview two people who have different opinions about cloning, but first I’ll explain what cloning is. Cloning is the name given to the process that creates identical organisms, called clones.
ME: Hi! James, what do you think of cloning?
JAMES: Well, I’m against genetic manipulation in general but cloning to me is the most horrible thing that has been created until now. God creates us! We are not allowed to create other organisms by our own hands. Each, person is unique, even animals are unique. What are we to change that?
If we stop, just for a while, to think we would be able to see all the consequences of cloning a human been. Imagine a person, physically identical to another person but younger, who was born with defects and is treated like a second-class citizen. Can you see a future in someone like this? I can’t.
Society is not ready to face the cloning challenge. That’s my opinion!
ME: Thank you James, your opinion is very important to us. Now, it’s your turn Sarah.
SARAH: I’m for cloning. I can't even agree with the arguments that James presented. God doesn’t have anything to do with cloning.
I recognize that cloning and genetic manipulation in general are difficult issues to talk and discuss. However, my point is that cloning brings us more benefits than disadvantages. If cloning was allowed sterile couples would be able to have kids and organs transplants would be easier because clones have the same DNA. See… cloning is the future
ME: Sarah, thank you for sharing your opinion with us.
Well, now that you have heard different points of view, tell us your own one.

Why people adopt different lifestyles? Veganism

I don’t know exactly why they choose different lifestyles but I think that they do it for feel good with themselves. Maybe they want to be different for the other people, they need find us personality, for example, the vegans choose these alternative lifestyles because they just don’t like eat meat or they respect the animals.
So I decided to write about veganism because this alternative lifestyle is very common in our days.
A vegan is someone who, for diverse reasons, chooses to avoid using or consuming animal products. While vegetarians adopt not to use meat, vegans also avoid dairy and eggs, as well as fur and cosmetics or chemical products tested on animals.
After I researched, I discovered that veganism is a natural extension of vegetarianism and an integral component of cruelty-free lifestyle. The practice of this alternative lifestyle is benefit because it helps to protect the animal’s lives, the environment and is a healthy lifestyle.
There are at least three reasons for vegans practice:
- People do not eat meat because they are against the animal’s violence, the animal’s kill. They think that animals should have their basic freedoms;
- Animal agriculture has a negative influence on the earth. It is an inefficient way of producing food, since feed for farm animals requires land, water, fertilizer, and other resources that could otherwise have been used directly for producing human food.
- Veganism is healthier. The consumption of animal fats and proteins has been linked to heart disease, osteoporosis, diabetes, hypertension, obesity, and a number of other debilitating conditions. Cows' milk contains ideal amounts of fat and protein for young calves, but far too much for humans. And eggs are higher in cholesterol than any other food, making them a leading contributor to cardiovascular disease.
The truth is that veganism reduces the risk of diseases.

Why endangered species need protection?


The earth is comprised of many different life forms, including plants, animals, humans, and other organisms. These various life forms are highly interdependent and have formed important systems that continually reshape the planet's landscapes, oceans, and atmosphere.
But with the growth of population this magnificent scenery has been destroyed. Same examples the causes of this destruction are: the constructions of the industries that need a lot of space what include de destruction of the habitats; pollution; over exploration of species; deforestation; the human activities and others.
Deal with The International Wildlife Federation (NWF) plant and animal species are disappearing at least 1,000 times faster than any other time in the last 65 million years. This problem is a worry situation. So we can conclude that species need our help.
While the most of humanity don’t aware or don’t care about the endangered species, animals and plants will continue to be threatened and this number will increase.
So we can conclude that species need our help. But why we need protect them?
Plants and animals hold medical, agricultural, ecological, commercial value so they need protected and saved for the future generations can experience their presence and value.
In order to combat this situation we need to assume an important role. One of the most important ways to help threatened plants and animals survive is to protect their habits permanently in national parks, nature reserves or wilderness areas.

Cloning


I researched and I discovered what cloning is. Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two.
There are many arguments for and against cloning, especially against cloning humans. In my opinion this is very confused because, for example, the twins, the natural twins, are often confused with each other and if you have a clone will be complicated.
Some arguments for cloning are: prevention of diseases (replacing cells damaged), creation of humans with identical genetic makeup to act as organ donors for each others, reju

venation, I think that are more important arguments for cloning.
There are good percentage of people against cloning because there loss of genetic variation, technology is not well developed, clones may be treated as second class citizens and unknown psychosocial damage with impact on the family and society.
I’m against cloning because cloning violates our rights. We are unique and if you have a clone they are stealing your identity. On the other hand cloning can help people or save lives.

Cloning may not be efficient because the clones born with defects and they have a short life expectancy.

The Melting of Glaciers

Everybody knows about climate change. This phenomenon is real and has been grown too fast. The warming of the climate system is now evident because the ocean temperatures are increasing, the glaciers are melting and consequently the sea levels are rising.
The human activities have been contributed by this increase. These activities, like deforestation, the burning of fossil fuels principally, cause emissions of carbon dioxide, the principal gas responsible for climate change. The concentration of this gas is increasing since the industrial revolution.
With that the Earth is getting hotter and this problem worries me a lot because many impacts are expected to occur in natural system in the future. With the melting of ice and snow are expected to increase flood risks in some areas while causing droughts in others. And then the species have to difficult to adapt of the warming temperature and they will go extinction.
The people have to make a reflection about your habits and if they are acting wrong they need to change.
