How science is boon? Give example.

Science is a boon to us in so many ways.  It has allowed
us to live longer, avoid pain from diseases, have more food, and have more ways to enjoy
our lives.

For example, science has made it so that we do
not have to fear diseases like polio and smallpox anymore.  Science has made it so that
farmers can grow more crops on the same amount of land.  Science has given us
televisions and the internet that are ways for us to enjoy our
lives.

Of course there are bad things about science, but it
has given us so many things.
