Science 7 - LAND and SEA BREEZE and its Characteristics
World In 2050

2. TECHNOLOGY
• Now just changing heart and limbs with machines is
tested while neither fully functional. But almost many
others are in the way.
• Now we spend a very long time in school to learn while
forgetting is an accepted fact, but soon our brain will be
equipped to a hard disk we just ask “please download cooking
every food” and then all of these information will be stored and
is retrievable whenever we want from this hard disk just like
other memories.
3. • Flying abroad will not need in a near future to Jets, but just
need own wings, like every bird. Soon traveling will change
from public to personal
• You can’t travel every day but you can hire a robot that
travel instead of you, go within the business sessions or go
to shopping by being your eye, ear and tongue.

5. ….THIS WILL DESTROY OUR EARTH
• Increase In population: Total population for
2050 will reach 9.078 billion.
6. • Population for Asia, Africa, Sub Saharan Africa, Middle East, North
America and South America will increase substantially
• World population growth will be concentrated in developing countries
for the foreseeable future

8. FOOD SHORTAGE
• The world’s population is projected to grow from about 7
billion in 2012 to 9.6 billion people in 2050. More than half of
this growth will occur in sub-Saharan Africa, a region where
one-quarter of the population is currently undernourished.
• In addition to population growth, world’s per capita meat and
milk consumption is also growing—especially in China and
India—and is projected to remain high in the European
Union, North America, Brazil, and Russia. These foods are
more resource-intensive to produce than plant-based diets.
•
9. • Climate change is expected to negatively impact
crop yields, particularly in the hungriest parts of the
world, such as sub-Saharan Africa.
• Growing water use and rising temperatures are
expected to further increase water stress in many
agricultural areas by 2025.
• Roughly one-quarter of world’s food calories are lost
or wasted between field and fork. Cutting this rate in
half could close the food gap by about 20 percent by
2050.
10. ENVIRONMENT
• Without new policies, by 2050, more disruptive climate change is likely
to be locked in, with global greenhouse gas (GHG) emissions
projected to increase by 50%, primarily due to a 70% growth in energy-
related CO2 emission.
• As a result, the global average temperature increase is projected to be
3°C to 6°C higher by the end of the century, exceeding the
internationally agreed goal of limiting it to 2°C above pre-industrial
levels.
14. TO KEEP NATURE A BEAUTY DO YOUR DUTY
Save the nature to save the future.
Environment is green but we need to make it clean!
It’s time to change our thinking into action! Just save the environment.
Make safer environment for better tomorrow.
Don’t be so mean, just be green!!
A drop of water is worth more than a sack of gold to a thirsty man
Don’t let the water run in the sink, our life’s on the brink!
When you refuse to reuse it’s our Earth you abuse
Water, water everywhere but not a drop to drink
Less pollution is the best solution
Don’t be a fool, cover your pool
Over Population leads to Over exploitation
Show you care, don’t pollute the air
Plant your seeds now, reap your rewards later
