Almost all types of water pollution are harmful to the health of humans, animals and plants. Water pollution may not harm our health immediately but could harm after long term exposure. Different types of water pollution affect health in different ways:

Heavy metals from industrial processes can accumulate in nearby lakes and rivers. They are toxic to marine organisms such as fish and shellfish, and subsequently to those who eat them. Heavy metals can slow growth; birth defects and cancer.

Industrial waste often contains many toxic compounds that are harmful to the health of seafood. Some of the toxins in industrial waste can have only mild effects while others can be fatal. They can cause immunosuppression, fertility failure or acute poisoning.

Pollutants from wastewater often lead to diseases that infect aquatic and terrestrial organisms through drinking water. Microbiological contamination is a major problem in developing countries, with diseases such as cholera and typhoid fever being the main cause of infant mortality.

Sulfate particles from acid rain can harm the health of organisms in rivers and lakes, which can lead to death.

The suspended particles in fresh water reduce the quality of drinking water for humans and the aquatic environment for marine organisms. Suspended particles can often reduce the amount of sunlight that passes through the water, disrupting the growth of photosynthetic plants and microorganisms. As a way to reduce water pollution, more advanced technical cleaning is needed. Some developed countries have wastewater treatment plants that remove pathogens. Maintenance, replacement and repair of leaky and faulty wastewater treatment infrastructure. Household septic tanks need to ensure pre-treatment on the spot before seeping into the soil.

1. You have a great influence on the young generation: As a teacher you have the opportunity to communicate and educate hundreds of young people. You are the one who directly molds children from early toddler days. So ask anyone who is the most influential person for a child? And the chances you hear the most are the teachers.

2. You are an actor, a rhetorician, a storyteller and a professional organizer: As a teacher you will have to take on all the above and even more. You will have the opportunity to face many challenges. You have to inspire, guide and entertain the children through the activities and experiences that they have experienced. In a day on the podium you have to show the ability to organize, plan, train and play.

3. Teaching is a very meaningful job: If you are looking for a job that brings joy, sublimation to you, the profession will give you all that feeling. Do not just teach things in books, direct them to do the right thing ... As a teacher, you also get help and education for young people in society as well as when you train a person Labor for the future.

4. Always cultivate, learn: "Study, learn, study forever" is the motto of those who love teaching. Knowledge is endless and therefore teachers, who need to cultivate, train and learn new things, new teaching methods through books or classes for teaching staff to not fall Back to the education of countries around the world. So they have the capacity to support future generations of the country.

Everyone respects and loves the teacher: If you are a teacher, you can be proud and proud to talk about your career. Teachers are beloved, respected for many reasons and perhaps the reason they are most admired is the patience, the ability to control and communicate to dozens of people.

There is no doubt that education is a top priority. However, these days the number of people having no wish to become teachers is increasing very strongly. This particularly worrying situation is taking place all over the world. Therefore, the authorities are doing their best to find out the reasons and a practical solution.
To start with, a wide variety of students do not pursue a career as teachers for the simple reason that the salary just helps them make ends meet. For example, my old classmate, Tom has to earn his bread hard to support his family.Today, everything is always increasing in price so it is essential for them to have stable jobs. Also, we are facing to the alarmingly high rate of unemployment. So plenty of graduate students are at all unsure about their jobs especially teachers.
Besides that, a lot of people are fed up with becoming teachers by reason of students' disrespect to their teachers. That students have bad behaviors towards their teachers is getting more and more popular. Despite the fact that they break the school rules and feel too lazy to study, they are not punished appropriately. In contrast to devoted teachers, a large number of teachers don't assume overall responsibility for their work. This makes their students misunderstand the importance of education.Ngoài ra còn những lí do gì nữa? Bạn có thể phân tích nhé.
In order to appeal more students to become teachers, we need to make attempts to find solutions. For instance, Ho Chi Minh City has brought in effective solutions like raising teachers'salary, providing dormitories in good conditions for teachers and decreasing working hours. Especially, Ministry of Education and Training had better abrogate the serious problem that teachers and students only care about achievements in lieu of the true result. It's high time they reformed the whole teachers.
To conclude, the shortcomings, although on the rise, can be purged at the grass-root level if proper preventive measures are taken. We really want major breakthroughs in education and training. It's for everyone and we ought to take action immediately.
