The exploration and development of safe alternatives to fossil fuels should be the most important global priority today. To what extent do you agree or disagree? Give reasons for your answer and include any relevant examples from your own knowledge and experience.

For the

last

few decades, people have been using fossil fuels

such

as charcoal, petrol, gas, and diesel as their main source of

energy

.

However

, overuse of natural fossil fuels not only have negative effects on the environment, but

also

reduced reserves to the verge of extinction.

Therefore

, many people believe that the

research

for green and safe

energy

should be the global priority these days. To a certain point, I agree with that, but some considerations should be cautiously measured as well. To start with, over consumption of fossil fuels results in certain threats to the environment. High emissions of carbon dioxide gases overwhelm the global warming to a dangerous extent.

In addition

to

this

, depletion of the ozone layer

also

speeds up.

For example

, a number of environmental researches proved that the effects of global warming and depletion of the ozone layer are four times as compared to the

last

few decades before.

Moreover

, the excessive utilization of natural fossil fuels

also

produces an alarming situation of diminution of their reserves.

For instance

, natural gas reserves of the Pakistan gas greatly reduced by just a few decades.

Hence

, it is the need of the hour to discover alternatives of natural resources as they have to eventually extinct. Despite all the positive sides of alternative

energy

, people should

also

be aware of several things.

Firstly

, the alternative

energy

methods should be controlled and checked firmly.

For example

, many countries, these days are using nuclear power as a main

energy

source. No doubt it is an environmental friendly way of meeting desired requirements. But, nuclear power plant should be properly maintained to avoid any adverse incident.

Secondly

, the expenditure for

research

and development of green

energy

worldwide is higher than the exploration cost of fossil fuels.

Therefore

, cost estimation should be made while searching for alternatives. In conclusion, exploration and

research

on alternatives to fossil fuels should be a targeted goal for the world because it will solve many environmental issues. But, numerous

research

should

also

be conducted with proper feasibility studies before taking any step.
