1. The film’s topic is ‘Global Warming’.
2. Biosphere, Lithosphere Hydrosphere and Atmosphere are the four spheres of earth.
Atmosphere has is the most affected sphere by the humans.
3. Greenhouse effect is caused due to a number of reasons and they are: industrial landfills and
waste, farming, increase in pollution, deforestation, burning of fossil fuels. Burning of the fossil
fuels like the natural gas, oil, coal has become an integral part of life. These non-renewable
sources of energies are used to produce electricity for transportation. A large amount of carbon
dioxide is generated when these fossil fuels are burnt. Forests are the major green areas on our
planet earth and is considered as a sink for the carbon dioxide. Trees and the plants take in
carbon dioxide take in carbon dioxide and release oxygen through the process of photosynthesis.
However, due to the large-scale development process, a large number of trees and forests are cut
down which has reduced the potential areas of the carbon sink. The increase in population has
led to the rise in the demand for the shelter, cloth and food. The opening of the new
manufacturing hubs in the towns and the cities has led to the increase in the harmful gases in the
atmosphere. Farming on the other hands contributed to extensive usage of nitrous oxide as a
fertilizer and this negatively contributed to the rise in the greenhouse gas.
4. Annual downturn in the production of the carbon dioxide is caused due to the turning of the
Northern Hemisphere towards the sun during the summer and the spring season. This results in
to the vegetation that are in the northern continent result into a full bloom and the plants absorb
more carbon dioxide and creates more oxygen.
