Earth is the only planet we can live on. It is our home. In recent years, our world is facing major environmental challenges and global crises, mainly caused by human activities. This video gives an overview of these planetary crises.
Before 1804, the world population was less than 1 billion people. It took more than one hundred and twenty years to double to 2 billion by 1927. Thereafter, however, the world population quadrupled in less than one hundred years. Today, our planet is home to over 8 billion people, and it is expected to surpass 10 billion by the 2060s.
Due to overconsumption and industrialization, our planet is facing numerous environmental challenges. Among them, climate change, pollution, biodiversity loss, and resource overshoot can be classified as quadruple planetary crises. These issues are destroying our living environment, threatening our health and lives, and jeopardizing our future.
The first planetary crisis is air and water pollution. According to the World Health Organization, 99% of the global population breathes unhealthy air that exceeds WHO air quality limits. Every year, air pollution kills more than 7 million people and unsafe water sources are responsible for over one million deaths worldwide.
The second planetary crisis is climate warming. Compared to pre-industrial levels, the global average temperature has risen by 1.6°C in 2024. Global warming has led to more frequent and severe extreme climate events in recent years. It’s expected that the global average temperature will exceed 2.0°C of warming by 2050 and reach 3.1°C by the end of this century.
The third planetary crisis is biodiversity loss. Currently, our planet is experiencing the 6th mass extinction event. Scientists estimate that the current rate of species extinction is hundreds of times higher than the average rate over the last 10 million years, and this rate will continue to accelerate over the next 300 years. Since 1970, global wildlife populations have declined by 68%. Currently, about one million plant and animal species are at risk of extinction.
Another planetary crisis is resource overshoot. Since 1970, humanity’s consumption of natural resources has exceeded what Earth can replenish. Over the past 50 years, Earth Overshoot Day has moved up by nearly half a year, from December 25 in 1971 to August 1 in 2024. According to the Global Footprint Network, humanity’s annual demand for natural resources is now equivalent to more than 1.7 Earths. This underscores the importance of sustainable development.
To mitigate climate change and achieve the global agenda for sustainable development goals, we must accelerate our efforts to modify our lifestyles, reduce greenhouse gas emissions, and promote sustainable practices. Together, we can make a difference. Let’s care for Mother Earth to ensure a sustainable future for all.
