One major problem in todays world is
global warming. Global warming is the increase in the
overall temperature of the Earths surface overtime.
Climate scientists, wildlife biologists, economists, chemists,
engineers and computer scientists all
work together to predict how the future
would be with the increase of global warming.
Some experts predict that the grass and trees
would be a deep green, the air would be clean
and crisp and vehicles would be powered by clean,
quiet-running fuel-cells and electric batteries
One of the main sources would be wind and solar power.
Other experts predict bad things. For example,
The air would be hazy and sour with pollution. The
grass would be spongy, and the sea level would have
by then risen dramatically worldwide. Some
cities would build seawalls, to prevent floods but
other cities, such as Indonesia, dont have enough
money to build seawalls. Scientists predict that tens
of millions of people would either die or become
homeless.
Many things cause global warming. Some scientists
say that human actions are responsible , some say that other causes
lie behind the warming. One thing that causes
