Earth's Sixth Mass Extinction: How Are Human Activities to Blame
The planet is facing an unprecedented loss of biodiversity, with scientists pointing out that human activities are driving the planet into its sixth mass extinction event. The continuous prosperity and expansion of mankind has put nature under unprecedented pressure. The destruction of ecosystems is becoming more obvious, making us wonder what the root cause of all this is.
The impact of human activities
Human activities, such as over-consumption of resources and a growing human population, have caused vertebrate populations to plummet by 68 percent since 1970, according to the report.
"Human activities, especially overconsumption, population growth and intensive farming, have led to widespread species extinctions."
The urgency of biodiversity loss
According to the Global Assessment Report on Biodiversity and Ecosystem Services, approximately 1 million species of plants and animals are at risk of extinction due to human factors. As human demand for land increases, habitat destruction is becoming increasingly serious. Since the rise of agriculture 11,000 years ago, humans have transformed about 70% of the Earth's surface.
Environmental degradation affecting women’s livelihoods
Environmental degradation particularly affects women's livelihoods. According to a report by the Food and Agriculture Organization of the United Nations, women and girls in rural areas bear a heavier burden when faced with land degradation, including the time and energy required to obtain basic living needs such as water, food and fuel, especially in small villages. The tragedy of gender-based violence is frequent.
Degradation of water resources
The depletion of clean water resources is becoming a global crisis. Only about 2.5% of the world's water is fresh water, and most of it is frozen in ice sheets, leaving less than 30% of it available for human consumption. With the increase of human activities, water pollution problems emerge one after another.
"Around one-third of the world's population currently faces water shortages."
Interactions between climate change and water resources
Climate fluctuations caused by climate change affect the supply of water resources. As the global climate changes, rainfall patterns, evaporation and groundwater replenishment rates are affected. These changes could lead to water scarcity in some areas and intensify competition for water resources everywhere.
The vicious cycle of population growth and environmental depletion
Rapid global population growth and economic development are the main drivers of environmental degradation. As demand increases, natural resources continue to come under pressure and the natural balance of the environment is disrupted. It is estimated that by 2070, there will be as many as 1.7 million new people.
Environmental impacts of agriculture
Agriculture is overly dependent on climate conditions and has a high demand for water resources. As the climate changes, changes in rainfall and evaporation will directly affect soil moisture and groundwater replenishment, posing serious challenges to agricultural production.
Water Resources Management and Future Challenges
In order to solve the increasingly serious water resources problem, countries urgently need to take effective water resources management measures. It is critical to develop water management strategies that adapt to new climate conditions and strengthen the protection of water resources.
Increase in consumption and environmental degradation
As population grows, the demand for natural resources will continue to rise, which will inevitably cause damage to the environment and ecosystems. Therefore, people have to think about sustainable development. Faced with such severe challenges, how can humans continue to coexist harmoniously with nature in the future?
