The main source of agricultural pollution: the abuse of fertilizers and pesticides

It's May now, and summer is about to enter
.
My hometown is in the countryside
.
I remember that when I was young, the happiest thing in the summer was to catch the monkey at night with my friends, and stick it with gluten during the day
.
Some places don’t eat those who can fly, but ours are different, we all eat
.
It is fragrant and crispy, especially delicious
.
It's just that this is just a matter of memory
.
I don’t know when it started.
In the summer, I can no longer hear the cicadas, and at night, I can’t catch the Cicada Monkey anymore
.
I hadn't noticed it before, but when I went back to my hometown and took a nap at noon the year before, I suddenly started to find that there was no call to know
.
According to my father, I haven't known it for several years, and the main reason is to fight drugs
.
Herbicides, fertilizers, pesticides, fertilizer and so on
.
Although there are more types of pesticides, the fertilizer efficiency in the ground is low.
When more drugs are used, while killing pests, some birds, ah, grasshoppers, have also been killed
.
Take Zhizhihou for example.
There were crops everywhere, but now if you want to eat, even if your home is in the countryside, you have to spend money to buy it
.
When he said this, his father's eyes were blank
.
I think of a book, "Silent Spring" written by American science writer Rachel Carson
.
In this book, Carson described the environmental pollution and ecological destruction caused by excessive use of chemicals and fertilizers, and finally brought overwhelming disasters to mankind, explained the pollution of pesticides to the environment, and analyzed the principles of ecology.
These chemical pesticides do harm to the ecosystem on which humans depend
.
I hope that this situation will not happen in our country
.
Speaking of the abuse of pesticides and fertilizers, the harm to the ecological environment is very great
.
The most important thing is that it causes non-point source pollution, not point source pollution.
A pollution is a large area. .
On the one hand, it damages the soil and kills the microbial flora in the soil, resulting in reduced fertilizer efficiency
.
Second, it will penetrate into the ground and cause pollution to groundwater
.
Pesticides and fertilizers flow into the river with rainwater, which will pollute the entire river and even the surrounding water system
.
The third is to destroy the ecological balance and destroy the entire ecosystem of mountains, paddy fields, forests, lakes, flowers, birds, fish, and insects
.
Moreover, it is difficult to recover from damage to the ecological system.
On the one hand, it takes time and on the other hand, it requires huge investment
.
I have watched a program made by Professor Wen Tiejun.
It seems to say that it would take hundreds of thousands of years to restore a square mile of land (I can’t remember the details, friends are welcome to correct me)
.
Fortunately, our country has begun to attach importance to the protection of the ecological environment
.
One of the five strategies for rural revitalization is ecological revitalization
.
Including some companies, they have also begun to seek research directions in green, organic, and pollution-free ecological agriculture, providing services for the three agricultural areas in terms of crop nutrition, plant protection, soil improvement, and microbial flora
.
As ordinary farmers, we still hope that we can start from ourselves and reduce the abuse of chemical fertilizers and pesticides.
Even if we use them, we must replace them with ecological, organic, and less polluting products
