Nowadays, pollution is one of the most talked about and important problems in the world. Some years ago, some people didn’t know about it completely. Nevertheless, today it is unquestionable. Pollution in cities, caused mostly by car emissions, is becoming bigger and bigger.



On the one hand, our lifestyle has changed. Some years ago life was very different. Our cities are full of pollution and it's very difficult to change this because... would you give up things like using a car? Most people don’t. In addition, our main energy source is oil. Petroleum is extremely polluting and the worst thing is that we use it every day. Because of all this, we know that it is very difficult to eliminate pollution in cities.



On the other hand, If no one initiates the change, it will never happen. There are many people who have already begun to change their habits to help the planet. They do simple things like not using the car so much and going walking to work. Besides, these actions may seem small but they help a lot. In addition, eliminating the use of cars or reducing it as much as possible is difficult but not impossible. In a city like Granada, it is even more probable because there are many types of public transport such as the tube or bus and you can use them instead of your car.



All in all, making a city like Granada a place without cars is very difficult, but we should try it. In my opinion, important people like the city hall should try to put measures to decrease  car traffic.

Nowadays, thanks to new technologies we can travel through the internet and make all the online purchases we want. However, online shopping is not as good as we think.



On the one hand, online shopping has improved our lives a lot. It allows us to compare prices and shop in a more relaxed way without leaving home. In addition, the store sends the product to our home and we can spend as much time as we want looking around and trying the product on. Besides, we can shop at the supermarket, look at clothes, electronics and whatever we want at any time of day because the online stores never close!



On the other hand, shopping online has disadvantages like we can get ripped off or we can end up being addicted to them. Normally, people have more free time at night because at that time we have finished doing our work and many people often travel through the internet at night. Moreover, according to statistics online shopping increases a lot at night. Besides, this is bad for us because we cannot rest properly.



To put it in a nutshell, online shopping at night is fine, but we must keep in mind that we have to rest at least 8 hours every night. In my opinion, online shopping is very good, but we must be careful with it.

Technology is always surprising us. More and more amazing inventions are appearing everyday. The airplane was made a long time ago, but have you ever seen an airplane that only uses solar energy? Well, yes, this has been made. A solar-powered aircraft flew over New York a few years ago. Unfortunately, the revolutionary plane, powered by some 11,000 solar cells on its oversized wings, had to land earlier than expected because of a problem on his left wing. However, that doesn't mean it's not a great invention.



On the one hand, solar planes are a great idea because today there is a lot of pollution and we have to do everything possible to reduce it. The fuel that planes carry, and that is spread all over the sky when they fly, is very polluting. Moreover, sunlight is a clean energy that never runs out. "It was a great success for renewable energy" Borschberg said.



On the other hand, as I said before, the plane had to land earlier because there was a problem in one of the wings; what would happen if it happened in a normal flight with a lot of passengers? Besides, solar panels are very sensitive and planes fly very fast so it is very likely that an accident can happen during a flight. Moreover, at night planes couldn’t take solar energy from the sun and they may run out of power.



All in all, solar-powered planes can be very good for us but we have to be careful because sometimes they can be dangerous. In my opinion, they should invent an airplane that has both solar panels and fuel.

Carpooling is a way of sharing transportation. The concept of carpooling is by no means a new one. From finding co-workers to commute with via the staff noticeboard, to sharing the school run, the idea of catching communal lifts to save money and ease congestion has been around long time before.





On the one hand, carpooling is very good for the environment because the fewer cars on the road, the less pollution there is. In addition, carpooling is good for us because it helps to have a better relationship and communication with everyone, especially if you're carpooling with your co-workers. Besides, nowadays in Europe carpooling is becoming very popular thanks to an app called "BlaBlaCar" with which you can take people in your car and earn money.



On the other hand, there are more and more people who have their own car and prefer to travel alone. In addition, many times we are afraid to use "BlaBlaCar" because we don’t know the people with whom we will travel. Moreover, many times car sharing is not good for us because, for example, if we travel in someone else's car to go to work and that person is late, then you will be late for work too. If you use your own car, you won't have this problem.



In conclusion, carpooling is very good because it helps the planet. In my opinion, people should do it more often.

Currently, technology is more and more present in our lives. Many teenagers and children already have their own mobile phone. Technology can have many advantages but it also has disadvantages.



On the one hand, technology is very good for us. It makes our lives easier. Besides, almost everybody is in touch with technology; not only in terms of mobile phones, TVs and tablets, but we also use technology in security alarms, gps and radios among other things. Nowadays our life wouldn’t be the same without technology.



On the other hand, technology has disadvantages as well. It is very common to see people addicted to substances such as tobacco or alcohol but... Does addiction to technology exist? Well, yes, it exists and especially it happens in young people. In addition, many times we don't realize it but we can spend hours and hours in front of a screen. Addiction to technology is a very serious issue and we should follow the example of the people who live in Silicon Valley. We all know that this is the center of technology but the children of those who live there are very far from technology, their parents are especially concerned about keeping them away from technology addictions.



To sum up, technology has many advantages but it can also be dangerous. In my opinion, we should use technology in a responsible way.

Nowadays, coffee is a very common drink all over the world. People usually drink it for breakfast or after lunch. Coffee has advantages and disadvantages.



On the one hand, coffee can be very good for us. There are many studies that show us that drinking a cup of coffee a day is good for us. Besides, it can help us lose weight. Acording to scientistics defences from the University of Nottingham drinking a cup of coffee can stimulate 'brown fat', the body's own fat-fighting defenses, which could be the key to tackling obesity and diabetes.



On the other hand, just as coffee can be very good for us, it can also be harmful. In addition, we have to be careful with the amount of coffee we drink; drinking more than three cups of coffee a day can be bad because with coffee our heart rate is increased. Furthemore, you also have to control the hours you drink it because if you drink coffee before you go to sleep you may have a lot of energy and you may not be able to rest properly.



All in all, drinking coffee is good but we shouldn't abuse it. From my point of view, we shouldn't drink coffee every day and if we do it, no more than a cup.

Nowadays there is rubbish everywhere and, as we all know, our planet is in great danger. Nevertheless, most people don't think about that when they throw rubbish on the ground or when they throw all the organic waste in the same container.



On the one hand, we don't probably take it that seriously but our actions, like buying a lot of food and then not eating it, are very harmful to the planet. Besides, we usually buy a lot of food and throw away what's left over, even more so on dates like this, Christmas. According to statistics, food — from the way it is grown and transported to how it is disposed of — accounts for about one third of global emissions.



On the other hand, many of us can do our part to reduce our carbon output in the kitchen by having a compost bin next to the trash can or swapping poultry for red meat in the fridge. In addition, this initiative has already been taken by some restaurants in California; if you pay a bit more for your dinner, restaurants can bill themselves as carbon-friendly, and farmers get extra money to invest in the most climate-helpful production practices, in a process known as carbon farming.



All in all, rubbish is very bad for the planet and we must control the garbage we throw away and the food we waste. In my opinion, if we get used to doing some small actions, we can contribute to save the planet.
