Question
Which of the following are signs of environmental stress?
- Ozone depletion
- Greenhouse gas emissions
- Deforestation
- All of the above
Hint:
- One of the main reason of environmental stress is pollution and pollution causes so many changes in environment.
The correct answer is: All of the above
All of the above
- Ozone depletion, deforestation and green house gases emission all of these are the signs of environmental stress.
- All the factors are connected to pollution either reason or result of pollution.
- Ozone depletion leads more approach of ultraviolet radiations from sun to earth which is very harmful to living beings.
- Deforestation is a stressing element for environment as trees are very important to fulfill our so many requirements like oxygen, wood, medicines etc.
- Green house gases leads so many dangerous diseases.
- So all of these are the reasons of environmental stress.
