Answer the questions.

1. It is difficult to determine what everyone wants to reduce as people have different priorities and concerns. However, some common issues that many people want to address include reducing poverty, reducing inequality, reducing crime, reducing environmental pollution, reducing healthcare costs, and reducing political corruption.
2. The pollution problem is complicated for several reasons. Firstly, pollution can come from many different sources such as industrial activities, transportation, agriculture, and households. Secondly, pollution can take many different forms such as air pollution, water pollution, and soil pollution, and each type of pollution requires different solutions. Thirdly, the effects of pollution can be cumulative and long-term, making it difficult to attribute specific health and environmental impacts to a single source. Additionally, pollution is often a global problem that requires coordinated action from multiple countries and international organizations. Finally, addressing pollution often requires trade-offs between economic growth, public health, and environmental sustainability, which can be challenging to balance.
