If you look straight at an object when it is nearly dark, you may find it difficult to see it. It is easier
to see if you look just to one side of it. Explain

When you don't look directly at something, its focused on parts of the retina mostly populated by rod photoreceptors.

Explanation:

rod preceptors are more sensitive to dim light than the cones are, which are clustered at the part of retina you use to look at something directly.

really dont know just need some points

1. efficient use of space

2. elimination of groundwater contamination

3. energy generation

4. lower carbon footprint
