ADMT Lesson 1 Environment - Darryl Lam

Will human beings' selfish acts bring about the Earth's doom?

Yes, human selfish acts will bring about the earth's doom as we are constantly polluting the environment, like waste materials being discharged from factories, vehicles, deforestation (e.g) burning of forest for agriculture purposes, the depleting of the ozone layer by chlorofluorocarbon also known as CFC. Now there is already a hole in the ozone layer and the UV rays which enters through that gap can kill plants. When the temperature rises as more green house gasses gets accumulated, more unwanted pest might bloom. most of our fossil fuels reserves will run out in about 50 years.

*The price of fossil fuels is getting higher every year. If the current consumption rate remains the same, proven oil reserves will last about 40 years. As for gas, it will be available for another 65 years if there are no interruptions in the supplies found in the Middle East and Russia, the world's largest gas and oil suppliers. Proven coal reserves should last another 155 years, but if we run out of gas and oil before then, we might have to use more coal to substitute energy sources. In that case, coal reserves wouldn't last more than 100 years. Also, the fossil fuel consumption rate is growing every year so we have even less time before the energy starvation begins.*

What we can we do to save the Earth?


We can save Earth by cutting C02 which is released from fossilfuels by using solar power, wind power, hydro power, geothermal energy, osmotic power, nuclear power, biofuels, carbon capture and storage, carbon trading and geoengeneering.

Protection of Water bodies: Careful and integrated land use planning, close monitoring of the quality of waterways, Ensure treated water meets WHO's guidelines.
