POPULATION Created by: Sophia Goldman, Alexandra Silva & Carina Almario CURRENTLY, The world Population is estimated to reach 8 billion by 2030
By 2045 The world population will be up to 9 billion.

As global population numbers continue to rise our planet is set to become more crowded then ever! Population Records It took from the dawn of man kind until 18OO for the world's population to reach 1 billion.
To reach 2 billion took 130 years.
3 billion took about 90 years.
To go from 6-7 billion took a mere 13 years. Top 5 most populated countries 1. China 3. United States 4. Indonesia 2. India 5. Brazil Benefits of Larger World Population -Having a greater domestic market
-Generating more ideas which improves productivity
-More jobs available
-A bigger army
-Attracting investors and companies

World Population
-More people means more wrappers and other coverings like paper bags= More Litter
-More people means more cars and other transportation vehicles= Air Pollution
-People need homes and companies need buildings; so where are they going to build it? The ecosystems around the world.=More Trees Being Teared Down, Less Habitat, Food and Shelter For Animals And Possibly Humans. THERE ARE 7 BILLION PEOPLE LIVING ON THIS EARTH Human Population Growth Can
Effect The Quality Of Life The world can only support so many people.
If this number grows beyond a certain point the world's resources per person will diminish significantly. This is due to the fact that resources are limited; but every person demands a certain portion. This is not sustainable and consequently leads to to smaller portions per person!! Is world Hunger Affecting our Population? 1 person dies every 3 seconds from hunger.
The world produces enough food to feed the whole world; the problem is that we don't know how to share it.
There are 925 million hungry people in the world; 75% of them are children Human Respecting Our Planet -Riding bikes instead of cars for
less air pollution
-Not throwing our garbage in oceans,
lakes, rivers ect. In our world people aren't aware of our planets well being. We need to educate our population to take care of our planet by:

-Not littering
-Using less electricity to avoid global
warming Water Pollution Littering Facts Did you know . . . -Canada makes most of their money by exporting basic needs to over populated countries like China or India.
