BIRTH CONTROL is the most important challenge for the world.
History has shown us what happens when animals over populate.
Rats, locus grasshoppers ,rabbits and kangaroos numbers got out of control, they spread disease and destroyed everything in their site. This is going to happen to us if we don’t limit the number of children conceived. The over population and mass movement of bodies around the World puts everyone at risk for infectious diseases. This started over 500 years ago with the Spaniards spreading small pox to North America.
Drought conditions are also increasing and if world food production fails we could be in for mass starvation. The world food inventory will only last about 2 years.
Over population has forced millions of people to live in dangerous areas such as low areas (subject to flooding), mountain sides (slides) by volcanoes, etc. etc. 100's of thousands of people have already died. (pictures of flooding)
WORLD POPULATION IS OUT OF CONTROL and family planning is a must ONE CHILD PER COUPLE.
