Climate change
Climate change is a serious environmental problem that affects the whole world.
It is caused by greenhouse gases in the atmosphere such as water vapour, carbon
dioxide, methane and nitrous oxide that absorb heat energy and emit it in all
directions warming the Earth’s surface and lower atmosphere. Consequently,
global warming is increasing day by day, causing alterations to the environment
and impacting human health. According to the statistics, the frequency of
extreme whether events, including hurricanes, droughts and floods, has
intensified globally over the decades. Scientists say that if we do not act soon, the
effects of climate change will be irreversible.
One thing we can do is encouraging the use of renewable energies instead of
fossil fuels. If we use energy that produces no greenhouse gas emissions, we will
reduce global warming. Moreover, the air pollution will decrease and the public
health will improve. A second answer is recycling in order to dispose of waste. In
this way, we will save energy, reduce greenhouse gases and preserve natural
resources. A third answer is walking or cycling instead of using the car.
In fact, air pollution caused by exhaust fumes and smog represents a serious
threat to public health. A final answer is raising awareness trough campaigns.
The best way to help change is staying educated and informed about climate
change. If we protect the environment, we can still make a difference to save the
planet.
