QUESTION: Which of the following is not an environmental problem?
A Afforestation
B Acid rain
C Loss of Biodiversity
D Genetic modification of food
Answer: Afforestation
| Environmental Problem |
Description |
| Climate Change |
· Greenhouse gases are the major cause of climate change, primarily release from human activities like burning fossil fuels and deforestation. |
|
Deforestation
|
· Deforestation is the depletion of trees and forests at an alarming rate, leading to a drastic change in the earth’s climate.
|
|
Loss of biodiversity
|
· The ongoing loss of species diversity and the degradation of ecosystems due to habitat destruction, pollution, over-exploitation of natural resources and invasive species. |
| Over population |
· The increasing rate of population growth as led to a shortage of resources. |
|
Genetic Modification of Food |
· Genetic modification of food can raise concerns about environmental impacts, biodiversity loss and potential health risks. |
|
Acid Rain
|
· Acid rain is form when atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain |
|
Air Pollution
|
· The presence of harmful substances in the air such as nitrogen oxides, sulfur dioxide etc. is a major environmental problem. |
| Ozone Depletion |
· The hole in the ozone layer leaves humans and wildlife exposed to harmful UV rays, posing health risks to them.
|
| Water Pollution |
· Water pollution harms aquatic life and disrupts ecosystems.
· It also poses health risks to humans who use these contaminated water sources. |
| Plastic Pollution |
· Non-biodegradable plastics harm wildlife and contribute to marine pollution. |
| Soil Erosion |
· Soil erosion reduces agricultural productivity.
