The Real Threats to Earth |
|
|
In 2012, people around the world were worried that the world would end according
to an ancient Mayan prediction. Luckily, nothing happened. However, it is
important to realize that Earth is actually in danger, not from asteroids or
rogue planets, but from our actions and their impact on the environment. There
are three major threats to Earth: global warming, loss of biodiversity, and
water and air pollution.
Global warming is a result of the release of greenhouse gases like methane and
carbon dioxide into the air when coal and oil are burned. These gases trap heat
from the sun in the Earth's atmosphere, causing temperatures to rise around the
world and changing climate patterns. In recent years, global warming has
worsened, resulting in unusual and extreme weather conditions such as droughts,
floods, and dangerous hurricanes.
Another problem the Earth faces is the extinction of plants and animals. Over
the past century, more than 10,000 plant and animal species have gone extinct,
and about 25 percent of all remaining species are in danger of disappearing.
This can cause ecosystems to collapse, which will have a severe impact on humans
as well. For example, the extinction of certain species of wild corn has
resulted in a loss of genetic diversity, making corn grown on farms especially
vulnerable to diseases and pests, which can affect our food supply. Therefore,
it is crucial that we acknowledge the danger of losing plant and animal species.
The third danger that we face is the pollution of air and water. Clean air and
water are crucial for human survival, but many cities around the world are
struggling with dirty air. For instance, in Beijing, China, air pollution
reached hazardous levels where it was not safe for people to go outdoors.
Similarly, water pollution can have a tremendously negative impact on our water
supply, and only 3 percent of the Earth's water is actually usable without
extensive processing.
To conclude, Earth is under serious threat from environmental damage, and it is
our responsibility to take action to protect it. Unless we act now, the
destruction of Earth is certain. |
