1. BIGGEST THREAT Humans are the Presented by Ennus Ong to Earth

2. Introduction Earth is home to million s of species. While our ancestors have been around for about six million years, the modern form of humans only evolved about 200,000 years ago. Humans’ intelligence, innovation and activities have modified almost every part of the planet. In fact, humans are having a profound impact on it. Indeed, humans’ intelligence, inventiveness and activities are now the drivers of every global problem they face. I agree to the statement that humans are the biggest threat to Earth due to the over industrialisation , climate change and overpopulation.

3. 1st body paragraph It is undeniable that over industrialisation is a significant factor humans are considered the biggest threat to Earth. The effects of over industrialisation such as the urbanisation or expansion of cities, a growing demand for raw materials can reduce biodiversity and disrupt the delicate balance of the planet . F or example, when industries produce goods on a large scale due to the growing demand, they often rely heavily on burning fossil fuels such as coal, oil and natural gas to power their operations. This combustion releases pollutants such a carbon dioxide, sulphur dioxide nitrogen oxides and particulate matter into the atmosphere. These pollutants can have a range of detrimental effects on both the environment and human health. Here’s how, carbon dioxide is a major to climate change, leading to global warming and the disruption of ecosystem. While sulphur dioxide and nitrogen oxides can react with other chemicals in the atmosphere to form acid rain, which can damage soil, waterways and vegetation. Additionally, air pollution from industrial activities can contribute to the formation of smog , which reduces visibility and poses further healthy risks. Therefore, over industrialisation poses a threat to Earth.

4. 2nd body paragraph Besides that, climate change is also a key reason humans are considered as the biggest threat to Earth due to the significant impact of over industrialisation . Climate change poses threats such as rising sea levels, extreme weather events, disruptions to ecosystems, and challenges to food and water security. For example, the melting of polar ice caps. The increased global temperatures caused by the release of greenhouse gases contribute to the shrinking of ice sheets in Antarctica and the Arctic. This leads to rising sea levels, posing a threat to coastal communities and ecosystems. Hence, climate change due to the impact of human activities is the reason why humans are the biggest threat to Earth.

5. 3rd body paragraph Overpopulation contributes to humans being considered as the biggest threat to Earth. With the global population surpassing 7.8 billion and continuing to rise, the strain on Earth's finite resources becomes increasingly pronounced. Overpopulation drives rampant deforestation primarily through increased demand for land to accommodate growing human settlements and agricultural activities. As the global population expands, there is a greater need for housing, infrastructure, and agricultural land to support food production. To meet these demands, vast areas of forests are cleared, particularly in regions with high population densities. Expanding human settlements require space for housing, urban infrastructure, and industrial development. This often leads to the clearing of forests to make way for residential areas, roads, highways, and commercial centres. So, overpopulation is one of the valid reasons why humans are the biggest threat to Earth.

6. Conclusion In conclusion, I strongly agree that humans are the biggest threat to Earth. Over industrialisation, climate change and overpopulation are the valid reasons why humans are a significant threat to Earth. Therefore, authorities play a vital role in taking lead to address the importance of environmental care. We should all take part in conserving natural resources and minimising negative impacts on the environment .
