  • We highly approve this move of the government for it is the people who will be greatly affected if the ozone depletion would continue to deplete in a faster rate. We all know that global warming is one of its effects and that it contributes to the unruly weather that we have in our country. Typhoons and floods, as well as drought, only bring disaster to our country. As a student, and a young citizen of the Philippines, I want to help in resolving this problem; but as what I have observed, there are still CFCs that are used and other causes of global warming are still in practice like illegal logging and wrong waste management. This article was dated a few years ago, and as far as I am concerned, I have not seen any improvement until now. As I’ve said, people are still practicing the wrong behaviors, and thus we are still suffering. Nonetheless, through reading this article, I am now more aware of these kinds of things that is happening in our environment. I realized that simply using aerosol cans (shaving creams, fire extinguishers, etc.) could contribute in harming the ozone layer of the earth. Then again, little things like this could be great like how CFCs created a hole in the ozone layer. We could do little steps and these little steps could be bigger as time passes by.
