Question

Give reason
1) The greenhouse gases are necessary for survival on earth .
2) Water in lakes , Streams and rivers in unfit for drinking.​

Answer 1

Explanation:

1. Greenhouse gases keep our planet livable by holding onto some of Earth's heat energy so that it doesn't all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.
2. Water from rivers, lakes, ponds and streams can contain bacteria, parasites, viruses and possibly other contaminants. To make surface water fit to drink, treatment is required. If the water is contaminated, this may put you at risk.

Answer 2

Stands for "Garbage In, Garbage Out." GIGO is a computer science acronym that implies bad input will result in bad output. Because computers operate using strict logic, invalid input may produce unrecognizable output, or "garbage."
