The environment is not in a good condition. This is a documentary that you must watch. The overall plot is as follows, and I strongly recommend watching it through the YouTube channel below.

The History of the Earth and Our Present

The Earth, born 4.5 billion years ago, is a small planet where 8 billion humans live today.
Life began on Earth about 3.8 billion years ago, and five mass extinctions have occurred since then.
Scientists warn that we are currently heading towards a sixth mass extinction. The cause is humans.
If we compress the history of the Earth into 24 hours, humans appeared on Earth 23 hours and 3 seconds ago.

The Birth of the Earth and the Beginning of Life

4.5 billion years ago, the Earth was hotter than today's sun. However, life began as water accumulated due to asteroid collisions and seas formed.
Water and carbon dioxide are essential factors for the birth and maintenance of life.

Earth's Mass Extinction and Carbon Cycle

Earth has experienced five mass extinctions, and all of these extinctions are related to the collapse of the global carbon cycle.
The rapid carbon emissions caused by human industrialization are rapidly raising the Earth's temperature. This is leading to large-scale environmental destruction and ecosystem collapse.

Climate Change and Extreme Weather

Recently, the Earth has recorded the hottest year in history, which is leading to various climate disasters.
As the Arctic temperature rises, the jet stream slows down, resulting in abnormal weather patterns with alternating cold waves and heat waves.
Disasters such as wildfires, droughts, and floods are occurring frequently around the world.

Wildfires and Droughts

Wildfires are occurring more frequently and more intensely due to global warming. This is destroying ecosystems and weakening carbon absorption capabilities.
Droughts are seriously affecting agriculture and food production, and the problem of water scarcity is becoming increasingly severe.

Oceans and Climate Regulation

The oceans, which cover 70% of the Earth's surface, play an important role in climate regulation. However, as ocean temperatures rise, the flow of ocean currents is weakening.
The weakening of ocean currents leads to the accumulation of heat energy, resulting in stronger hurricanes and typhoons.

The Future of the Earth and Our Role

The climate crisis is no longer a future problem. It is a reality that has already arrived.
If we don't act now, our time on Earth could stop.
Every year on the last Saturday of March, there is 'Earth Day', a time for the whole world to think about the Earth together. We need to deeply reflect on the message that the darkness of this day throws at us.

Conclusion

We need to act now to protect the Earth. Efforts to prevent climate change and environmental destruction are urgent. Let's start with the small things we can do for the future of the Earth and humanity.
