Population Growth

We studied with population growth. We needed to watch 4 videos, take screenshots and explain them.

Video 1

This is explaining that a lot of population can bring problems to the environment,
such as we need more food, so we need to destroy places
to build houses, we need to produce more and this produces more carbon dioxide, etc.

This mean that first we need to be responsible with the environment
because we destroy it, for example, when we cut toomany trees or when we pollute.
When we’re responsible, the environment would be better.

This picture shows that in 8 C. E. there were less than 1 billion people.
Most of them where in south Asia or Europe.

However, this picture shows than in 2050 there are supposed to be 9 billion people.
This mean that in 34 years, the population can grow from 7
billion to 9 billion and we will need to duplicate our resources.

Video 3

Here we can see that in 1000 there were 0.3 billion people. Most of them were
in China, India and the rest of Asia. There were less people in North and Latin America.

On the other hand, in 2011 there were 7 billion people.
As in the other picture, most of them were in China, India and the
rest of Asia and there were less people in North and Latin America.
There were more births and more death than in 1000.

In this population pyramid from 1993, we can see the population of Canada,
China, Japan, Russia, Rwanda and USA. In Canada, there are more people
in the reproductive area like in China, Japan, Russia and USA.
On the other hand, in Rwanda, there are more people in the pre reproductive area.

In this population pyramid from 2016, we can see that the population has changed.
In Canada, China, Japan and USA there are more people in the reproductive
area and in the post reproductive area. In Rwanda, there are more in the pre
reproductive area and in the reproductive area; and in Russia,
there are more in the reproductive area and more women in the post reproductive area.
