Ways to educate children to care for plants
Nature is fair. Grass grows carefree on the ground and has beautiful flowers. Whether you appreciate it or not, it grows happily in its small place. Children should cherish these nameless flowers and plants.
Grass has a strong vitality, no matter what soil grass can grow healthily, and it can also produce all kinds of small flowers to decorate nature. Look how well these two little blue flowers bloom in the mud of the slag stone.
Weeds are very important. They grow taller in the spring breeze. Wildfire never completely devours them. You can live in a place with soil. It is incredible that this short grass tree can grow more than four bright flowers.
From the fact that grass grows in a harsh environment, we must realize that children's education should find grass from the actual environment. This example tells children to overcome their fragile psychology in life and study and live tenaciously like grass.
Small pine trees, like grass, can grow green and thrive in any environment, regardless of spring, summer, autumn and winter. Look how fast these little pine trees are ascending.
Children should cherish young trees, because trees are natural oxygen bars, which will bring infinite fresh air to human beings. Look at the little girl admiring her beloved little pine tree.
Some children don't know that trees are good friends of human beings and don't cherish and destroy plants. Look, these children are tugging under the willow tree, and the willow tree yells with pain.
The importance of caring for plants
1, people must rely on plants to provide oxygen, and only plants can make oxygen. If a person doesn't eat or drink for a few days, he may die in a few minutes. Oxygen is the first need of human life activities! An adult breathes about 20,000 times a day, inhaling 0.75 kg of oxygen and exhaling 0.9 kg of carbon dioxide.
2. The breathing of animals and humans and the burning of substances also consume oxygen and release carbon dioxide. So, isn't there more oxygen in the air every day? Don't! The reason why this kind of crisis has never happened between heaven and earth is that plants are both "factories" of natural oxygen and "broad markets" of carbon dioxide.
3. According to statistics, the broad-leaved forest of 1 hectare can produce 750kg of oxygen and eat 1 1,000kg of carbon dioxide every day in the growing season, so as long as there are 654.38+10,000 square meters of trees, one person can be supplied with oxygen, and the oxygen in the air can be kept basically constant. On the contrary, if there are no plants, the oxygen on the earth can be used up in about 500 years.
