Admittedly, $132 billion—the world's total government space spending in 2024—is a large sum. However, this represents only about 0.12% of global GDP. Far from being waste, space exploration is a smart investment. To start with, space exploration creates jobs. NASA's activities bring in over $70 billion every year and support more than 300,000 jobs across the United States. Besides, satellites monitor our changing climate. They take pictures of polar ice caps and track melting rates, giving governments solid evidence to make climate policies. Finally, space technology saves lives directly. The COSPAS-SARSAT satellite system picks up emergency signals from ships and planes.Then, it works out the exact location. After that, rescue teams are sent immediately.Consequently, over 50,000 people have been rescued since 1982. All things considered, space spending pays for itself many times over—through jobs, climate data, and lives saved. We should continue to invest in it. Homework: Write an argumentative essay of around 100 words arguing space exploration is a waste of time. Make sure to use the structure and expressions learned in this class. Goodbye $
