Over the last few decades, the impact of human activity on the Earth's ecosystems has become an increasing concern among scientists and the public alike. Deforestation, pollution, and climate change are just a few of the challenges facing the planet's varied ecosystems, from tropical rainforests to coral reefs. Ecosystems are complex networks of plants, animals, and microorganisms interacting with their physical environment. These interactions are critical for sustaining life, providing services such as air and water purification, pollination of crops, and climate regulation. However, human activities have altered almost 75% of the Earth's surface, threatening biodiversity and the services ecosystems provide.
One of the most visible impacts is the loss of habitats, leading to a dramatic decrease in biodiversity. Species extinction rates are now estimated to be 100 to 1,000 times higher than natural background ones. Conservation efforts are underway worldwide, aiming to protect remaining natural habitats and restore damaged ones. The success of these efforts is vital not only for the health of the planet but also for human wellbeing, as we depend on the Earth's ecosystems for our food, water, and air. Despite these challenges, there is hope. Renewable energy sources, sustainable farming practices, and conservation initiatives are examples of how we can reduce our impact and help ecosystems recover. The choices made by individuals, communities, and governments over the coming years will be crucial in determining the future of the Earth's ecosystems. Question 26: What is the passage mainly about?
