Yes well that depends who you look at it. When you water a plant it does not just go into the plant but, the roots do such it up in a mater of time, from there water gets put into plants.
To save plants from drought
Water provides for people, animals and plants. Plants use it to grow and people and animals use it so they will not get dehydrated.
The coal filters the water so the plants don't get infected from water that is not changed a lot. Some people believe it benefits the plants too but I am not one of those people.
they cannot use alot of water to water plants
Plants are like people, they need water to survive.Food and water supply the nutrients the plant needs. Especially if it is out in the sun, the plant would burn from overheating.
One is that people are not getting enough water. The drought his affecting the nature because there no water for the plants. One is that people are not getting enough water. The drought his affecting the nature because there no water for the plants.

People,animals and plants are affected by air pollution
No. Green plants were on the planet, long before there were people. Green plants need carbon dioxide, water, sunlight, soil, and seeds to live. They do not need people.
