Why is the presence of ozone above the troposphere important for the survival of living things on Earth?
It warms Earth's surface.
It helps in cloud formation.
It makes jet flying more comfortable.
It offers protection from the Sun's harmful UV rays.
The greenhouse effect is a natural phenomenon. Without a natural greenhouse effect, the temperature of the Earth would be about -18 degrees Celsius instead of 14 degrees Celsius at present. Why are scientists concerned about the greenhouse effect?

Planting trees in wider areas is not possible; Earth has many desert areas.
Human activities like burning fossil fuels and deforestation enhance the greenhouse effect.
The human population is increasing rapidly; more carbon dioxide will be released into the atmosphere.
