Influence of human beings on the world's ecosystem is leading to the extinction of species and loss of bio-diversity. What are the primary causes of loss of bio-diversity? What solutions can you suggest?

Human beings are taking over the earth and toppling the intricate balance of the world's ecosystem. Even if one species becomes endangered or extinct, it would create a domino effect and harm other components of the ecosystem, and lead to a loss of biodiversity. In the following essay, I will outline two primary reasons for the loss of biodiversity caused by humans Firstly, with rapid rise in populations, more forest land is being cut down to accommodate the needs of the people. Since there is an increase in the number of people, there is a subsequent need to satisfy their food supply. Rampant deforestation is taking place to make space for agriculture that feeds this population. Plantations are the prime example of clearing forests for food supply that leads to the loss of biodiversity. Although it might seem like trees are being planted in replacement, there is a big difference. Plantations have a singular kind of tree, such as banana plantations in Haiti. A forest on the other hand supports a wide variety of not just trees, plants, shrubs and a range of animals that symbiotically help each other thrive. In this manner, cutting down to a singular type of tree destroys biodiversity. Additionally, humans have caused harm to even natural elements of the earth. By polluting air and water bodies especially, we have caused the death of millions of sea creatures. For example, factories that release effluents into the sea increase the temperature of the seawater. Moreover, surface temperature also increases due to the excessive carbon dioxide from factory smoke leading to global warming. Certain species can only survive in cold temperatures, such as corals. The Great Barrier Reef, a line of rich coral life along the coast of Australia, is slowly vanishing due to rising temperature levels. Corals are important for the survival of other species and they also act as a cleaning mechanism for the oceans. This example elucidates how the loss of one species can impact the whole ecosystem. If humans can meet their food needs through alternative methods such as hydroponics that do not require soil, forest land can be preserved. As for factory pollution, the only way to really stop the damage to the environment while meeting our needs, is to have stringent policies that force factories to curb pollution levels. Innovative inventions of renewable energy can help in this regard. To conclude, deforestation for the purpose of agriculture, and pollution of air and water are two causes of biodiversity loss. If humans can change their ways and adopt alternative methods that are environmentally friendly, we can exceedingly protect biodiversity and the world's ecosystem at large.
