Letters | Why does Hong Kong take paper recycling so lightly?
- With the paper the world wastes each year, we could build a 3.65-metre high wall stretching from New York to California

Trees produce oxygen for humans and animals to live and breathe. In fact, one tree can provide enough oxygen for three people a day! Far too many people usually just throw away paper instead of recycling it. One billion hectares of forest have been cut down in 40 years, and between 2001 and 2019, a total of 386 million hectares of forest were lost globally, representing an almost 10 per cent decrease in tree cover since 2000.
With the paper the world wastes each year, we could build a 3.65-metre high wall stretching from New York to California. That’s over 4,600 km!
It is a shame that so much paper is being wasted, and not being used to produce other paper products that are reusable, such as books and storage boxes. Paper can be recycled, but the problem is that so many people don’t do it.
Not wasting paper and recycling means saving trees, and water, and contributing to helping the world become a better place for all of us.
