Drinking water is very important to your health. As a child, you know that every molecule of water is made up of two hydrogen atoms and one oxygen atom. You may also know that it's fun to fill the water gun with water.
At least before the headmaster catches you, you may not have learned much about how much water you need to be a healthy person. Your body is estimated to have five percent of water. Your blood is mainly water.
Your muscles, lungs, and brain contain a lot of water. Your body needs water to regulate its temperature and provide nutrients to you Some organs. Water also transports oxygen to your cells, cleans waste, and protects your joints and organs.
Once upon a time, human beings did not have to consider protecting their own environment. There were very few people on the earth, and natural resources seemed to be infinite. Today, the situation is different.
The world has become too crowded. We are consuming our natural resources. If we continue to do this, human beings on the earth will not be able to survive.
We realized that if we caught too many fish from the sea, there would soon be no fish. With modern fishing methods, more and more fish are caught. We know that if too many trees are cut down, the forest will disappear, we continue to use powerful machines to cut down more fish and more trees.
We see that if the river is polluted by waste, we will still die, and the waste will still be put into the river. We know that if the population continues to grow at the current rate, there will not be enough food in a few years if we eat more Vegetables, less meat, what can we do to solve these problems, there will be more food to grow, more land to grow crops, five times more land to feed humans than land to raise animals, and our natural resources will last longer. If people eventually use modern methods of birth control, if we educate people to think about the problems we are going to face, the world's population will not grow so rapidly A better and cleaner planet.
Wealth and happiness some people think that wealth can bring them happiness. In fact, most of them get wealth through honest labor. They work hard and overcome many difficulties.
They feel very happy and happy. Even though their money is a kind of happiness, some people think that wealth can not bring them happiness. For example, when a person gets a fortune, family members will come from different places and try to communicate with each other He shared wealth, and then, they would quarrel with each other, try to share more, sometimes even bloody fighting and killing.
In my opinion, this is a terrible result. I think there is no doubt that wealth will bring happiness, especially in modern society, if you have money, you can live a comfortable and colorful life, but we should have a correct attitude towards wealth Remember that money is not everything. Wealth and health are more important than wealth and health.
Different people have different opinions. Some people prefer wealth and think that money can't bring everything. But without money, one can't do anything.
In order to accumulate more money, they can do anything, but others think that health is more important. Once I lose health, there is a lot of money for me It's useless to say that it's useless. I love wealth, but I value health more.
Everyone wants to live a happy life, so they try their best to earn money, so that they can live a comfortable life. But if happiness and comfort are at the expense of health, in my opinion, if there is no health money, how can they be happy? No one will agree Healthy rich people will also be happy, so try our best to keep healthy and happy wealth.
