Humans as one of the components of the environment will live calmly and safely if the environment is in a balanced state. However, due to the actions of some people who are not responsible for natural disasters, it also disturbs the tranquility of human life. Among these human activities is the disposal of waste that causes pollution. In addition, excessive exploitation of natural resources often results in environmental damage, landslides, floods, disease outbreaks, and the extinction of several types of plants and animals. How efforts should be made to prevent and reduce these things? Let’s take a look at the reviews about human activities that can disrupt the balance of the following environment.
Human Activities That Can Disrupt Environmental Balance
1. Household Waste Disposal
The remaining detergent that is disposed of into the river can be considered liquid waste. The entry of waste into the river causes the amount of oxygen in the water to decrease. As a result, a number of aquatic animals (especially fish) will have difficulty breathing. This symptom is characterized by the amount of gill movement in the fish. If this is allowed, the fish will die. In addition, water pollution will disrupt the food chain because one of its components is dead. What should be done so that the disturbance caused by the use of chemicals is reduced? The following are things that can be done to prevent river pollution.
- Use a detergent brand that says environmentally friendly or biodegradable (biodegradable).
- Do not throw washing water directly into rivers or the ground. Flow through a special drain.
2. Use of Fertilizers and Pesticides
Apart from detergents, other chemicals that can disturb the environment are fertilizers and pesticides. These chemicals are actually beneficial. However, if it is overused it can disturb the environment. How can fertilizers disturb the environment? Fertilizers can fertilize plants and wild plants around agricultural plants.
Water hyacinths live in waters, such as lakes, ponds, or rivers. Initially, only a few water hyacinths were found in the river. However, due to the fertilizer waste being dumped into the river, water hyacinth grows rapidly. The water hyacinth grows to fill the entire surface of the water. As a result, various animals that live in the river will find it difficult to move. In addition, they will have difficulty getting oxygen to breathe. Many aquatic animals die from a lack of oxygen.
What about pesticides? Pesticides that were originally used to kill pests can also kill insects. For example, ladybugs that are useful for killing pests will also be killed. Excessive pesticide spraying and not according to procedures will cause soil contamination. Soil contamination can kill earthworms which are useful for fertilizing the soil. With the killing of the worms, the moisture in the soil decreases. In addition, worm-eating animals will lose their food source. Finally, this can break the food chain present in the soil environment. How about the environmental balance in the forest?
3. Forest Destruction
Forests provide various needs of living things, especially for humans. However, humans can act as forest destroyers. Illegal logging activities to clear new land can threaten the balance in the forest. Even the increasingly rampant poaching threatens the preservation of animal and plant species. In fact, forests play a role in maintaining environmental stability on Earth. Have you ever heard of the slogan “the forest as the lungs of the world”? The abundance of plants in the forest provides oxygen needs for animals and humans. Another function is that with good forest conditions, erosion and flooding can be prevented. So, what will happen if the forest is destroyed a lot?
