Body
Transition: Let me start with the first problem in the world.
I. Over population is significantly increasing within the last 50 years.
a) Fertility is remaining the same there is no stop to it.
i. Between 1999 and 2011, global population …show more content…
Establishing a rule toward the world of limit of 2 children per family would not help the Earth.
b) It’s not just having children, but the fact that elderly people are living longer due to the help of science
i. According to the World Health Organization, “the average life expectancy is 79 years old for women and 74 years old for men”. ii. In 1900, the numbers were 48 years old for women and 46 years old for men. iii. In reality it has increased about 35 years per person and this is only within the last 100 years.
c) Not enough land for the people.
i. If the population increases we would Lack of personal space. Leading to more demand for constructing homes and we might not have enough crop fields for agriculture
Transition: know that I talk about the main point of overpopulation let talked the effect and the demands of resource for the 8 million people.
II. Water limitation in the world.
a) 85% of the world population lives in the driest half of the planet.
i. “663 million people do not have access to safe, clean drinking water and 2.4 billion people live without proper sanitation”(UNICEF. Pg 8). ii. Mostly in developing country, water is not safe to consume, leading cause of death for children under five years of …show more content…

c) The supply of fresh water is limited, but demand is increasing as the population grows. “By 2025, when world population is projected to be 8 billion, 48 countries containing 3 billion people will face shortages” (Narasaiah, 2004, pg.103).
i. The earth is covered with 70 percent of water, but only 2.5 percent is fresh water. ii. Out of the 2.5 percent fresh water only 1 percent is easily accessible and the rest is underground and reservoirs. iii. Rest of the water belongs in the sea.
Transition: so if we have a lack of space for crops and limitation of water, leaving the developing countries with poor growth of crops.
III. Food supply is increasing as much as population rises. United Nations Food and Agriculture Organization estimates that about “795 million people of the 7.3 billion people in the world, or one in nine, were suffering from chronic
