18 Questions
What are the respiratory diseases that humans and animals may suffer from when polluted air is inhaled on a long-term basis?
chronic bronchitis and lung cancer
How do dirt particles in polluted air affect the skin?
They accumulate on the skin and block the pores, preventing the skin from excreting oils and dead skin cells, which can lead to skin infections.
What are some diseases that people may contract from drinking polluted water?
cholera and diarrhoea
Why might aquatic animals die due to pollution?
due to the poisonous pesticides used in agricultural activities or toxic waste released by factories
What is a consequence of industrial activities and agricultural activities on the water supply?
contamination of the water supply
What is the overall effect of pollution on human health?
it leads to many health issues
What is a consequence of the release of untreated chemical waste by factories into rivers and lakes?
Water pollution occurs, promoting the growth of algae in rivers and lakes.
What are some examples of waste gases released by factories during production processes?
Carbon monoxide, sulphur dioxide, and nitrogen oxides.
What is another type of pollution caused by factories working 24 hours a day?
Noise pollution.
How do modern agricultural activities contribute to pollution?
Through the use of various types of pesticides to kill pests.
What is a health issue related to air pollution?
Respiratory problems.
What is the overall effect of industrialisation on the environment?
It contributes to pollution.
What is the consequence of industrial and farming activities on the environment?
Water, air, and noise pollution
What is the effect of open agricultural burning on the air?
Highly pollutes the air
What is the impact of land clearing on soil?
Soil erosion and loss of fertility
How many hectares of land are burned every year in Indonesia for farming purposes?
More than 200,000
What is the impact of pollution on humans and animals?
Negative health effects
What is the air quality index during land-clearing seasons in Indonesia and neighboring countries?
Above 200
Study Notes
Industrialisation and Pollution
- Industrialisation is a major cause of pollution, with 98% of factories producing chemical waste during manufacturing processes.
- Untreated chemical waste is often dumped into rivers and lakes, promoting algae growth and causing water pollution.
- Factories also release waste gases, including carbon monoxide, sulphur dioxide, and nitrogen oxides, contributing to air pollution.
- Noise pollution is also a byproduct of industrialisation, with machines operating 24/7 and causing disturbance to nearby residents.
Agricultural Activities and Pollution
- Agricultural activities, such as the use of pesticides, contribute to pollution.
- The cultivation of crops often involves clearing large areas of land, leading to soil erosion and sedimentation in nearby water bodies.
- Open agricultural burning, still practiced by some farmers, highly pollutes the air, with Indonesia alone burning over 200,000 hectares of land annually.
- This leads to unhealthy air quality indexes, surpassing 200 during land-clearing seasons.
Health Issues Caused by Pollution
- Long-term inhalation of polluted air can lead to respiratory diseases, such as chronic bronchitis and lung cancer.
- Research shows a high possibility of people suffering from skin infections due to pollution, which causes dirt particles to accumulate on the skin and block pores.
- Polluted water consumption can result in diseases like cholera and diarrhoea, while aquatic animals may die due to poisonous pesticides or toxic waste.
- Pollution leads to many health issues, affecting both humans and animals negatively.
