Hey baby! We’re at 7 Billion…

Hey baby! So you may have heard that the world’s population has recently hit 7 billion.

Yes, that’s a lot of people, but what issues will we be facing in the coming years? The ability to have a decent life comes to mind, not to mention access to clean water, food, shelter, and education. These are the issues we should be working on improving for the people who are here living on this earth.

To find out how you fit into these 7 billion, you can visit this BBC link.

I did this and found out my number. What surprised me most is the increase in the world’s population that has happened since I was born. Is it alarming? Well, yes. And estimates say that by 2083 the world population will reach 10 billion.

It said as well that in Canada, like many developed countries, the birth rate is slowing and most of the birth rate increase is happening in less developed countries. Places like China and India, for example. Not surprisingly, it said that working-age people like me will support increasing numbers of older people during the next decades.
