Agriculture

• Technology has had the biggest impact on peoples
  ability to produce food. Humans can grow more
  food and harvest it faster allowing the
  population to grow.

5
Agriculture

• Technology has helped agriculture in several
  ways
• People now have tractors and machines that can
  help them farm. When people use machines to farm
  it is called mechanized farming.
• People can make chemical fertilizers that help
  plants grow faster and bigger.
• People use pesticides to kill bugs that destroy
  plants.

Energy Usage

• Technology has allowed humans to use different
  types of energy such as solar power, wind power,
  geothermal power, energy from fossil fuels, and
  energy from nuclear fission.

10
Energy Usage

• Most of the power in the world is produced by
  fossil fuels coal, oil, and natural gas.
  Burning fossil fuels causes pollution and there
  is a limited amount of oil and coal that is
  available.
• Nuclear power is another option but many people
  dont think nuclear power is safe and it produces
  radioactive waste.

leveled off in the mid 1980s.

Transportation

• Technology has radically changed how humans get
  from one place to another place. Besides the
  invention of the internal combustion engine there
  are also better roads and a network of railroads
  that make it easier and faster to transport
  humans and goods.

Automobiles

• Cars have had an impact on just about all aspects
  of life in the modern world.
• Cars allowed people to live farther from their
  work, therefore suburbs grew up around cities.
• Cars need roads and parking lots so the advent of
  the car led to massive road construction projects
  and more parking lots all over the world.

The automobile has led to this, lucky us!

Airplanes

• Airplanes make it easier and faster to travel,
  but they have also changed the world because
  people must build airports which in turn create
  noise and other environmental concerns.
