Write at least two（2) main causes of the disruption of the natural cycle. 

Deforestation: Cutting down trees disrupts the carbon cycle, reduces oxygen production, and destroys habitats.
Pollution: Contaminants from industrial, agricultural, and urban sources harm ecosystems and alter natural processes.

Supplemental Knowledge:

Disruptions in natural cycles can have profound impacts on ecosystems and biodiversity. Two main causes of such disruptions are:

Human Activities:

Deforestation: The large-scale removal of trees disrupts the carbon cycle by reducing the number of trees that can absorb carbon dioxide during photosynthesis. This leads to increased levels of CO2 in the atmosphere, contributing to global warming.

Industrial Pollution: Factories and vehicles emit pollutants such as sulfur dioxide and nitrogen oxides, which can lead to acid rain. Acid rain alters soil chemistry and water bodies, disrupting nutrient cycles and harming plant and animal life.

Knowledge in Action:

Imagine a small coastal village that relies heavily on fishing for their livelihood, yet due to industrial activities upstream, pollution has significantly polluted their river. This pollution has disrupted their ecosystem's natural cycle, leading to fish population decrease due to polluted waters and reduced breeding grounds.

Simultaneously, global warming has caused sea temperatures to increase dramatically, further stressing marine life and coral reefs near the village are bleaching due to ocean acidification removing key habitats for many fish species. Human activity combined with climate change has had devastating repercussions for their economy and food security in this village.

This real-world example serves to emphasize how closely linked our actions are with natural cycles, and how disruptions to ecosystems may ripple throughout and eventually affect human communities.
