41. Causes of Climate Change
Climate change means that the Earth's weather is
warmer and less stable. Scientists say that one
the main causes of climate change is human
. Over the past 150 years, people have burned
lot of coal, oil, and gas for energy.
fuels give us electricity, heat, and power for
, factories, and airplanes. However, when they burn, they
gases such as carbon dioxide into the air.
gases trap heat around the Earth, like a
, and make the planet warmer.
Another cause of
change is cutting down forests. Trees absorb carbon
and help clean the air. When people cut
too many trees for wood or to make
for farms, the Earth loses an important way
control carbon dioxide. Sometimes forests are burned, which
the problem worse by adding more gases to
atmosphere.
Farming and raising animals also cause climate
. Cows and other farm animals release a gas
methane, which is very strong at trapping heat.
farming methods use chemicals that also add harmful
to the air.
Factories and industries add even
greenhouse gases. Making cement, steel, and other products
a lot of energy, which often comes from
fossil fuels.
Even daily human activities, like driving
or using a lot of electricity, add to
change. Each small action may not seem like
, but together, they have a big effect on
planet.
In short, climate change is caused mainly
burning fossil fuels, cutting down forests, farming practices,
industrial activities. Understanding these causes is important, because
helps us find ways to reduce the problem
protect our planet for the future.
