when light fall on plants there is photo synthesis process accouring. our earth is like a green house due to ozone layer so that day by day it becomes hotter and hotter due to blokage of radiations by ozone layer.
It would be really hard for other ecosystems to adapt to the climate so it would be a really bad thing.
It would die.
earthquakes and volcanoes
try it and you will find the answer you would have to pay for it.
you would explode
it would just keep growing.
Eventually there will not be any more to fish.
The leaves would dry out
If a plant is kept under green light for an extended period, its photosynthesis will be affected as green light is not efficiently absorbed by chlorophyll, the pigment responsible for photosynthesis. This can lead to a decrease in the plant's food production as it may not receive the necessary light energy required for photosynthesis.
It's not "kept" anywhere. It's converted into chemical energy.
All will tell lie.
rust, lots of rust.
