1) The global human population has grown rapidly since the 1800s due to advances in modern medicine, sanitation, and nutrition. The population grew from 1 billion to over 6.8 billion people currently and is predicted to reach 9 billion by 2050. 2) As the population increases, so does its environmental impact through increased resource consumption, waste production, and pollution. Individuals will produce over 53,000 kg of garbage and consume 18 million liters of water in their lifetime. 3) Daily human activities like electricity and fossil fuel use, food and packaging production, and waste disposal damage the environment. The growing population threatens to exceed Earth's limited resources and carrying capacity if environmental impacts are not reduced through conservation
