Causes of Human Influence on the World Ecosystem:
1. Habitat Destruction: Human activities such as deforestation, urbanization, and infrastructure development lead to the destruction and fragmentation of natural habitats, causing many species to lose their homes and leading to their eventual extinction.
2. Pollution: Various forms of pollution, including air, water, and soil pollution, have detrimental effects on the environment and wildlife. Pollution disrupts ecosystems and can directly harm or kill species, especially those that are sensitive to changes in their environment.
3. Overexploitation: Human exploitation of natural resources, such as overfishing and overhunting, has resulted in the depletion of many species. When species are overexploited beyond their capacity to reproduce, they become vulnerable to extinction.
4. Climate Change: Human-induced climate change is a major driver of species extinction and loss of biodiversity. Rising temperatures, changing rainfall patterns, and extreme weather events disrupt ecosystems and make it difficult for many species to survive.
5. Introduction of Invasive Species: Human activities, such as international trade and transportation, have led to the unintentional introduction of non-native invasive species into new habitats. These invasive species often outcompete native species for resources, leading to the decline and extinction of native species.

Solutions to Address the Issue:
1. Conservation and Restoration of Habitats: Efforts should be made to protect and restore natural habitats, including forests, wetlands, and coral reefs. This can be achieved through the establishment of protected areas, reforestation, and sustainable land-use practices.
2. Sustainable Resource Management: It is essential to adopt sustainable practices in the management of natural resources. This includes implementing fishing quotas, regulating hunting, and promoting sustainable agriculture to ensure the long-term viability of species and ecosystems.
3. Pollution Control: Stricter regulations and enforcement are needed to reduce pollution levels. Encouraging the use of renewable energy, implementing waste management systems, and promoting environmentally friendly practices can help mitigate pollution and its impact on biodiversity.
4. Climate Change Mitigation: To combat climate change, efforts should focus on reducing greenhouse gas emissions. This can be achieved through transitioning to renewable energy sources, improving energy efficiency, and adopting sustainable transportation methods.
5. Prevention and Control of Invasive Species: Measures should be taken to prevent the introduction of invasive species and control their spread. This includes stricter regulations on trade and transportation, early detection and rapid response systems, and the removal of established invasive species.

In conclusion, human influence on the world ecosystem is undeniably leading to the extinction of species and loss of biodiversity. However, by addressing the causes through habitat conservation, sustainable resource management, pollution control, climate change mitigation, and invasive species prevention, we can work towards protecting and preserving the rich diversity of life on our planet.
