Hi there!
I'm not too sure how to save the victim's life in a situation like this, but you SHOULD NOT give oxygen to a victim who has suffered from an explosion at close-range, while under positive pressure.
Answer:
Humans are responsible for the environmental pollution in many ways . Some of the points are as follows :
1 ) People throw the wastes wherever they like instead of using dustbins .
2 ) The various types of gases from the industries which harms the nature .
3 ) Cutting off the trees . ( people can cut but also must plant a new one )
4 ) Farmers using different chemical substances in high amount in the crops .
5 ) Burning plastics , tires etc .
This was my way to answer the question , if you need then you can write in paragraph .
let me know if its incorrect . :-)
