Pollution and Human Impact Questions
Which of the following is NOT a significant environmental impact of textile production?
-
Water pollution
-
Air pollution
-
Solid waste generation
-
Renewable energy consumption
D
Correct answer
Explanation
Textile production is a major consumer of energy, and much of this energy comes from fossil fuels, which contribute to air pollution and climate change. Renewable energy sources, such as solar and wind power, are not typically used in textile production.
What percentage of global water pollution is caused by textile production?
B
Correct answer
Explanation
Textile production is a major polluter of water, accounting for approximately 20% of global water pollution. This pollution is caused by the use of dyes, chemicals, and other substances in the textile manufacturing process.
The Stockholm Convention on Persistent Organic Pollutants (POPs) aims to eliminate or restrict the production, use, and release of which group of chemicals?
-
Persistent organic pollutants (POPs)
-
Heavy metals
-
Radioactive substances
-
Greenhouse gases
A
Correct answer
Explanation
The Stockholm Convention aims to eliminate or restrict the production, use, and release of persistent organic pollutants (POPs), which are chemicals that are resistant to degradation and can accumulate in the environment and human body.
