Answers
Answer:
1.Public transportation contributes to a healthier environment by improving air quality and reducing oil consumption, and through better land-use policies. It also helps to expand business development and work opportunities. And, it is critical for emergency situations requiring safe and efficient evacuation.
2.The need of the hour means the most important need of a particular time. And, similarly the establishment of the no smoking zones is also one of the most important necessities of the present time period. Because,the number of smokers is increasing everyday in the current situation.
3.THERE IS AN URGENT NEED OF USING INEXHAUSTIBLE RESOURCES BECAUSE THEY ARE UNLIMITED SOURCE OF ENERGY WHICH CAN BE REPLENISHED EITHER BY MAN MADE EFFORTS OR NATURALLY. WE SHOULD MINIMISE THE USE OF FOSSIL FUEL AS THEY ARE EXHAUSTIBLE SOURCE OF ENERGY AND TAKE 1000 OF YEARS TO REGENERATE AGAIN.
4.Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.
