Ⅱ. Choose the best answer（选择最恰当的答案）
Global warming is one of the most serious problems in the world today. As more carbon dioxide is produced, the temperature on Earth keeps 21. Sadly, the countries that suffer 22 are usually the ones that produced the least pollution.
Many discussions about climate change tell people to recycle more, eat less meat, or ride bikes. These ideas are helpful, but they focus too much on individual actions. The truth is that many big causes of pollution come from factories, energy systems, and government-supported industries. If we only talk about personal lifestyle changes and ignore these larger systems, we 23 not solve the problem.
The science is clear: carbon dioxide traps heat in the air and leads to higher temperatures, droughts, floods, and the loss of many species. But public discussions often make the issue 24 simple. People blame cars or cows, and expect individuals to fix the problem by changing their daily habits.
However, personal choices 25 won’t stop climate change. For example, the energy used to heat homes in winter around the world creates as much pollution as all cars combined. Making an electric car also produces a lot of carbon dioxide. This shows that emissions come from the whole systems, not just from individuals.
Developing countries face an even harder challenge. 26 people in these countries try to improve their lives, carbon emissions increase naturally. Asking them to cut emissions may limit their chance to grow, especially when richer countries 27 huge emissions in the past.
Food production is 28 difficulty. To feed the growing world population, farms use fertilizers and raise animals that produce strong greenhouse gases. Modern farming won’t be done without creating some pollution.
Technology may help, but it is extremely expensive. Removing carbon directly from the air would cost trillions of dollars every year.
Climate change is everyone's responsibility, but not 29 the way people often think. Individual actions are good, but they may not replace strong government policies. Leaders must support clean energy, control pollution from large industries, and invest in new technologies. Only with both personal effort and systemic change can the world make 30 real progress.
