More and More

Today days we are almost seven billion people in planet earth, in 2050 there would be three billion more, thats ten billion people. this is because we have discovered and invented incredible things. For example, in 1928, the penicillin was dis covered by Alexander Fleming, and this was our first antibiotic discovered, and now we know all antibiotics come from fungi in the roots in the trees. Penicillin has saved millions of lifes all around the world.
In 1900s the life expentancy was in about 35 years, but medicines can now cure people so they live more.
Another problem is that if most people live, and most reproduce and have two children, 2x2x2x2... this will make more births than deaths in the world and it would get over populated and there will be not enouth space for everyone and what is worse, there would be no resources and we will all die.
