Future of World Population

World's population is sure to go up unless human beings get population education and awareness. It will definitely increase if people don't think of birth control. The population of third world countrie will definitely double within  twenty years. The cities like New Yokr, Kathmandu, Shanghi, New Dilli, Islambad, Mumbai, and so on will be over crowded. Consequently thousands of children in the under developed Asian and African countries will possible die with malnutrition and hungry. There will be the scarcity of the food and other resources like water, fuel and furniture. The construction of more houses that are needed for the more number of population will erode the nature habitats of the animals. The forest will slowly disappear.
But in a condition that the human being got a good amount of population education, the situation might get reversed. If educaded people might maintain child space which will ultimately control the birth. The birth control might make the world a safer place to live in.
Besides,the government will indeed work out against population growth.
Worlds government will stay together to control the birth rate in the world.
