Introduction

This topic is about the changes that occur in all of us during the transition from childhood to sexual maturity (also known as puberty). We will try to gain an understanding of these changes. We will begin with a study of the reproductive systems of males and females. We will need to learn a great deal of scienctific terms for this unit. We will learn about the process of joining male and female sex cells (gametes) and the female menstrual cycle. We will study the process of birth and look at reproductive technologies that assist this process.

World Population

As the world population continues to grow and life-expectancy continues to increase, there is concern that the Earth will not be able to sustain such growth.
The questions that arise here are; Does every human have the right to a child? Where which areas is human population mostly concentrated? Which countries have higher birth rates than other countries?

World population clock - Approx 7 billion human beings on planet Earth now. We are currently living beyond Earth's carrying capacity (how many humans it can support at our rate of resource use, resources include food, water, forest resources, etc). It is expected that the human population will increase to approximately 9 billion by 2015 - this is overshooting the capacity of Earth to support so many humans, and is expected to then reduce to 8.5 billion and then remain approximately constant.

Here is a Graph of Human Population Growth ... what could be said about the trend in the graph since the industrial revolution...?

What are some of the policies that aim to reduce the human population?



Do the Japanese face extinction?

Some countries, such as Japan and most European countries (eg. Norway, Italy) have very low birth rates. As their governments wish for their economies to continue to have new working force age people (approx 15-60), they wish for birth rates to be higher - that is, it is for mostly economic reasons. How do you feel about this? Should these countries have such policies to attract people to have children (eg. baby bonuses, cheaper childcare, paid maternity leave)?
