With the development of science and technology, people's living standards are getting higher and higher, environmental problems are more and more serious, you found it?
Let's talk about water pollution! Gas stations and other factories always put the water without purification to the river, resulting in small fish without home. 50% of our country can not use clean water, this figure is not terrible? So saving water is imminent, you still waste it?
Let's talk about the problem of reducing trees! Now a lot of trees have been cut down by us, so the dust storm came, the flood came, nature to revenge us. We all know that the use of disposable chopsticks are made of trees, if each of us every day can use a pair of disposable chopsticks, one year down can keep ten thousand trees, see this time, you are still presumptuous Behavior?
Let's take a look at the sky, the blue sky is gone, the white clouds are hidden, is it really gone? No, they are just "smoke" by the smoke from the factory.
These are water caused by it? Are our own human beings, if not felling of trees, garbage, a reasonable discharge of purified sewage, I believe our planet will be beautiful. Protect everyone from the earth, let us work together to protect the environment!
With the continuous development of science and technology, the increasing number of cars, emissions of emissions has caused serious pollution, perhaps, a few years later generations, hundreds of years after everyone, perhaps because of air pollution and death. Now, twenty percent of the people on earth every year are killed by drinking contaminated water, and if this continues, will the earth become bare after tens of thousands of years, like the moon?
According to the statistics of scientists, every year, more than 20 percent of the trees are withered by exhaust pollution every year. More than eighty percent of our useful bacteria die, and everyone may feel very exaggerated, but it is true. Followed by contaminated waste water, waste gas and so on. Is human error?
How much I hope that we can cherish every thing around us, every animal, every beneficial bacteria, because it is possible, in tens of thousands of years later today, they are gone.
Animals have warned against humans;
Bacteria have warned against humans;
Every innocent life warned us.
"Human, do not harm yourself, do not kill us again!"
Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.
Horizon a meteor across, breaking the sky quiet. I heard my grandmother said, as long as the meteor before the disappearance of the desire, the desire will be achieved. So, I promised a wish, you think I promise what is it?
Standing next to the river, see the vicious is struggling to hear the moaning, smell the smell. I think: the current water pollution is too serious, how can we improve it? In fact, the problem in the final analysis or rely on people's consciousness, as long as people consciously, do not throw litter, factory discharge of sewage in a timely manner, then we The river pollution will improve how much ah, our home will hold up a small piece of blue sky.
Looking at the dead grass, I gently stepped on the top, looking up at the blue sky, want to see the sky look like, can be vague to see, the original is black smoke strange. Recently, due to the development of social productive forces, the factory has been set up to release harmful substances - black smoke. Black smoke not only pollutes the environment, but also endangers people's physical and mental health. If the factory black smoke can be purified after the discharge, that the quality of the air will be much improvement ah, the physical and mental health hazards will be reduced how much ah!
The original forest tree when the boss, first in the woods to dominate the sand. Yes, the present forest is no longer green, but yellow. Recently, people in order to meet the economic needs, and constantly cut down trees, so that the sand out of trouble. Huang Sha not only pollute the environment, but also affect people's lives, even more damaging is to bring people to bring economic losses and affect people's physical and mental health. There are so many crimes in the sand, why do people want to release it out? People are not very stupid? If people can be a variety of trees, less cutting trees, it can not ban the crime of sand? The environment, life will have a great improvement.
Pollution of the devil and ...
I wish the wish is that all people can protect the environment, let us breathe green, enjoy the health of it! My wish is not a dream!
