Science
always have been developing and improving. As time passes by, rate of the
development of science became more faster. In this new century there would be
massive scientific innovation that ever before. I believe changes that new century
bring would be source of the energy, and better medical treatments.

This
new century will be using different energy sources. Fossil fuels are almost
used up. At this rate, in 45years there would be no fossil fuels left for us to
use. Not only that, usage of fossil fuels creates a lot of problems. Most of
environmental problems we are facing are caused due to the over use of fossil
fuel. One of the best examples of environmental problem caused by fossil fuel
would be global warming. Global warming is serious and global problems. Since
fossil fuels are almost worn out, and have a lot of side effects, in this new
century we will find different energy sources. The possible ones would be
renewable energy such as energies using sun, wind, waves and more on. Those
energies would be infinite and way more environmentally friendly. Nuclear
fusion or hybrid energy which is highly efficient also can be the upcoming
future energy. Since we can not suddenly erase our civilization and live life
in the nature, there will be tremendous amounts of demands for energies, and
fossil fuels would be replaced with our upcoming future energies.
There
would be many huge changes in this 21st century. Changes in
cultures, customs, habits and more on would follow. But the biggest changes
will be followed by development in science. Development of science will provide
solutions for status quo of scarce fossil fuels. Further more development of
medical science would lengthen the life span of human which will cause diverse
results in cultures, and societies.
