Earth is called The Blue Planet, because 79% of our planet is water but only 1% of this is drinking water. There are approximately 7 billion people living in the world. We have many issues arising from growing human population, because the resources are not unlimited. One day our food and water will run out. ~ Felype
There are many people living in every country. In Mexico, India and Africa people suffer because of water shortage, lack of food and diseases. The Earth is really crowded. Therefore in some countries such as India and China the governments forbid people to have more than one child. However, people tried to change this rule. In one of the towns of India, they make sure all families and children are educated.~ Gabriela
From the year 1800, human population has increased a lot. Because humans learned to fight against diseases and other dangers in the world. Their life span became longer. Although technology grows faster, resources become less and less. Some people waste resources and some don't have enough of them. Humans destroy nature for their needs. The animals decreased because of food and water shortage. If humans keep making babies, eventually they will finish all the resources The Earth has. ~ Zuqiang
In China the government says every couple is allowed to have just one child, because people do not have enough food and water. They have a similar situation in India as well. In Mexico people haven't got enough water, because it is very hot. Mexican people have to pay for water and they need to be careful so they don't waste it. In Africa couples have got many children, because many of them die quite young. ~ Marina
