How will human live with the ecosystem, It's commensalism or prasitism?
The Human and The Ecosystem
We are the most smart animals in this world , Do you think the natural create us because we are the hope for it?
The chemical fertilizers ,and the insecticides and the herbicides has been a lot of harm to the ecosystem in present. This is the diagram was drawn by me…
And the small diagram
The diagram about how it happened?
There are many ways will be disrupt a food chain or food web. For example..
2. use of insecticides
3. use of fertilizers
1. The monoculture
The monoculture, means plants only a little types pf crops. This thing happened because some style of crops sell a good price or it easily to grow. So many people plant them. This will become a lot of harm to the natural. Some of the animals doesn’t eat this kind of crops. They will die or they will have a migration. The migration maybe worse then dead. It will cause more complex things that maybe mort creatures will be in a big trouble. And some animals or insects will eat this style of food. They will be in crazy to eat this crops and these animals in other place will have a migration too. But where they will go isn’t other place. They will get here and clean away all the crops. This kind of crops will also get into trouble. At last no one get any benefit . The food web lost balance and all the creatures(including human) will get into trouble.
2.Use of insecticides
The use of insecticides is pretty popular in this time. Because some of the insects will eat the crops. That’s made human lost a lot of crops and money. So human invented this things to easily killed the insects. But this thing is like a poison. Insects can’t eat it, neither human or other animals. Not only the pests , But most of the insects will be killed . Birds have no insects to eat and they also can’t eat the crops. Because there has insecticides(poison) on it. Many birds will dead. And when human are water the crops .The insecticides will get into water and get into rivers or ponds .The fish and plants in water will be poisonous. Human eat them and become sick. The fish will die . At last. The food web become imbalance because of insecticides.
3. Use of fertilizers
The fertilizers is been used a lot today. Because it can make the crops grow more quick and improve yield. So it’s fall in love by all the farmers. What harmful will it be? It doesn’t like poison. It’s safe, right? Actually not. The fertilizers can make the crops grow crazily, But not only crops. It’s all the plants. When farmers water their crops. The fertilizers will get into water and will be into the river. The plants in river will grow crazily. The fish can’t breath at all and dead. The insects which eat the plants in water will eat these plants. And there amount will be increase quickly. At last. The food web become imbalance. Again, By the human.
We can make trouble. Then we also can save the trouble. So what’s the way can not only keep us benefits. And also protect the ecosystem?
Here they ARE!!!
1.grow a variety of crops instead if only one crop. The animals will not have a migration any more because there has enough food. And there is no other animals come here. Everything keep in balance easily.
2. Use insects to fight other insects. This is known as biological control of insects pests. In this way. You don’t need to use the poisonous insecticides at all . It won’t caused any trouble to other biotic. But attention. You must make sure the insects you used has a enemy here(maybe a kind of birds) Or everything will be get into trouble again.(happy happy)
3. Instead of chemical fertilizers. Try organic farming using natural fertilizers for crops. In this way. You don’t need to worry about will it caused a large number of plants in water grow. It will make everything keep what they looks like before.
