Read the following passage about the Global Environmental Crises: A Call for Unified Action and mark the letter A, B, C or D on your answer sheet to indicate the best answer to each of the following questions from 31 to 40.

A major United Nations report by nearly 300 scientists from 83 countries shows humanity faces serious environmental problems. Climate change, loss of wildlife, damaged land, and pollution are all connected and make each other worse. [I] Scientists say past efforts have been too separated and not enough. As the old saying goes, we reap what we sow—years of harming nature now put our future at risk. The report suggests moving to a circular economy that respects nature's limits. We need everyone working together: governments, businesses, banks, industries, and ordinary people.

Current situations are very worrying. Gases that trap heat reached record levels in 2024, even after many climate meetings. Scientists predict Earth will warm about 2.4°C above past temperatures by 2100, much higher than the 1.5°C Paris Agreement goal. [II] This means more extreme weather, dry periods, heat waves, and wildfires. Already, 40% of the world's land is damaged, and pollution kills approximately 9 million people each year. Climate change aggravates land problems, forest loss, and species disappearance.

Although changing everything costs money, it makes economic sense. [III] Reaching zero emissions and saving nature needs about 8 trillion yearly investment. However, around 2050, the good results will be worth more than the costs, growing to 20 trillion per year by 2070 and possibly $100 trillion later. Lead scientist Bob Watson says countries should stop using only GDP to measure success because it doesn't show whether growth is sustainable or harms the environment.

Political problems remain significant. International cooperation is getting weaker when we need it most. [IV] The United States left important agreements, supported fossil fuels, and rejected scientific findings. Still, scientists have some hope. Climate researcher Katharine Hayhoe says fixing climate problems helps solve other environmental emergencies. Michael Mann believes leaders must choose what is right instead of what is politically easy because the risks are huge. Change is still possible, but time is running out quickly.
