Overcrowding is common in many parts of the world and causes a lot of problems. Overcrowding in a country can have a significant economic impact. It can cause less natural resources. More traffic will make the air dangerous by releasing toxic gas. In addition, excessive population will make people who do not have enough housing, many of them unemployed, so there will be many slums. When life becomes difficult, there will be many crimes. Children in these places do not have enough schools to study. Finally, the environment will be severely polluted: the air environment; Water Environment; soil environment; ... It was horrible !!!

Được tôn vinh là ánh sáng mở đường cho một cuộc cách mạng năng lượng, nhưng giới khoa học mới đây đã chỉ ra chính những chiếc đèn LED lại đang đẩy mạnh tình trạng ô nhiễm ánh sáng toàn cầu, kéo theo những hậu quả nghiêm trọng đối với sức khỏe con người và động vật.
Nghiên cứu đăng tải trên tạp chí Science Advances ngày 22/11 phân tích dữ liệu vệ tinh cho thấy những buổi tối trên Trái Đất đang có xu hướng trở nên sáng hơn, với diện tích sử dụng ánh sáng nhân tạo ngoài trời tăng với tốc độ 2,2%/năm trong giai đoạn 2012-2016.
Các chuyên gia nhấn mạnh đây là một vấn đề nghiêm trọng vì ánh sáng vào ban đêm đã được xác định là làm rối loạn đồng hồ sinh học ở người và tăng nguy cơ các bệnh ung thư, tiểu đường cũng như chứng trầm cảm. Ánh sáng vào ban đêm thậm chí có thể giết chết nhiều động vật như đèn thu hút côn trùng hay làm nhiễu loạn khả năng định hướng của chim hay rùa biển.
Chris Kyba, nhà vật lý của Trung tâm Nghiên cứu Địa chất Đức và cũng là chủ nhiệm công trình nghiên cứu, cho rằng vấn đề không nằm ở công nghệ đèn LED, vốn được ưa chuộng nhờ đặc tính tiết kiệm điện.
Phát biểu họp báo về công trình nghiên cứu mới, ông Kyba cho rằng vấn đề là việc con người có xu hướng lạm dụng khi dùng quá nhiều đèn với suy nghĩ họ đang sử dụng công nghệ tiết kiệm. Các nhà khoa học gọi đây là "hiệu ứng đảo ngược."
Theo một nghiên cứu năm 2010 công bố trên tạp chí Ecological Economics, những buổi tối quá sáng không chỉ ảnh hưởng tới môi trường tự nhiên mà còn gây thiệt hại gần 7 tỷ USD hàng năm do "tác động tiêu cực đối với đời sống hoang dã, sức khỏe, ngành thiên văn và lãng phí năng lượng."
Travis Longcore, chuyên gia của Đại học Nam California, cho rằng kết luận của nghiên cứu mới "không có gì bất ngờ" đối với những người đã bỏ nhiều năm theo đuổi vấn đề này. Chuyên gia này cho rằng con số 2,2% mà nghiên cứu đưa ra là "không bền vững."
Các giải pháp được đề xuất bao gồm sử dụng các nguồn sáng cường độ thấp, tắt đèn khi không sử dụng, dùng đèn LED ánh sáng ấm thay vì ánh sáng xanh hay tím để hạn chế tác hại đối với sức khỏe con người và động vật, và quan trọng nhất là thay đổi cách suy nghĩ của người dân về việc quá dựa dẫm vào nguồn sáng nhân tạo vào ban đêm.

- Quy Nhon is a small city in the Central Coast Vietnam. It belongs to Binh Dinh province that is known as martial arts land of Vietnam. This is not a tourism destination so it's peaceful, quiet, friendly people, cheap price. Like another Coast cities, it has very fresh sea food. Now, some places are developing to attract tourists but if you want to find somewhere not crowded, this is.
You can go to the top of Vung Chua mountain by motorbike (from Ghenh Rang, near the Queen beach). It takes about 15 minutes. This is the best place to see all of the beautiful city, graceful sea with natural beauty of Thi Nai lagoon, Phuong Mai peninsula and Thi Nai bridge - the longest cross-sea bridge of Vietnam.

English is a common language that is quite diffucult to understand and to learn. But there are many countries that speak English, making English as their native language. America is one of them. America is an English-speaking country. English is a common language in America. As you know, America is very developed, and this developed country is using 1 international language, that is English. And as I know, most Americans speak Englishs .Due to the fact that a few hundred years ago, Colossians discovered. Although American and English are 1, but in there are still some words different from English like football (soccer) or some words with "u" missing word like color (colour) or neighbor (neighbour). English is very diverse, and our country is starting to use English as a second language.

Unlike in the old days, we could only learn English through radio books, television and in school. There are many more ways to learn English today, especially through the internet, smartphones and many English learning centers opened up. There is no compulsory method to learn English, but each person must find a suitable way to learn it effectively. Many people will think that learning English is difficult, but what we need to do is get our own way of learning and an effort. Using the right vocabulary and sentence structure correctly requires a long process, but we can always invent new learning methods. We can go to parks or join English-speaking clubs for a chance to speak with foreigners, and that helps us improve our grammar and accent. Books, movies, songs, and newspapers in English are also what help us get used to how foreigners use it. The key to learning English is that we should not try to remember everything in the notebook, but we need to meet and practice it in real life. But learning English can be more effective when we can create our own learning styles.

As far as you know "space" can mean all things that exist, it is a vast space. The space travel is always a hot topic being put on the screen or hit. top-selling newspaper products in the world. You must have seen many pictures of astronauts suspended in the cabin, eating dishes in small tubes such as toothpaste, drinking water in the form of spheres? And you have always assumed that this is the life of astronauts in space, there are some interesting phenomena happening now in the absence of gravity. On the one hand, the fluids in your body tend to move up above your head, so your facial skin will be inflated like a balloon, and the absence of gravity can make you feel disoriented. A trip into space always has fun things, but there are also some issues that make it difficult for you to stay for a while. However, one thing is for sure that the experiences you have in the universe will be ones that you will never forget.

About the film:Tham khảo:
My favorite movie is cartoon “Tom and Jerry”. Tom is a cat with blue and white color. He keeps the house for a normal family and has a very free life. His job is chasing Jerry day by day. Jerry is a brown house mouse. He usually lives in the deep cave behind the wall. Although they hate each other so much and always find ways to hurt opponent but when Tom or Jerry falls into really dangerous situations, then both become another savior. The film is an endless confrontation between Tom and Jerry, bring plenty of laughter for the audiences. I love this film because when I watch it I feel very glad, feeling like returned to childhood.
About the festival:tham khảo
Tet is the most well-known holiday in Vietnam. It is celebrated all over the country. It mostly goes on for 3 days: 1st, 2nd and 3rd of January - Lunar Calendar.
Before Tet, people who work far away from home go back to join their family for the holiday. People clean up their houses, decorate it with Mai and Dao blossom, as well as other bonsais.
On Tet holiday, people cook feasts with various dishes to show dedication to their ancestors. A dish of 5 different kinds of fruit is also put on the altar as a tradition.
People go to relatives' and friends' places to wish them good luck, prosperity and health. Children are always excited since they will get their "salary" - lucky money in the red envelope on this occasion.
Tet is the oppoturnity for everyone to gather with their family, to rest after a long hard-working year, to refresh and prepare for a brand new year of greatness and happiness.
