China Is Both the World's Largest CO₂ Emitter and Renewable Energy Producer

Wu Zetian (624–705 AD) is the only woman in Chinese history to assume the title of Empress Regnant, ruling China in her own name from 690 to 705. She rose from court concubine to empress consort under Emperor Taizong, then effectively ruled through her husband Emperor Gaozong, and finally seized power outright. Under her reign, Tang China expanded its territory, and she reformed the civil service examination to favor talent over aristocratic birth, recruiting brilliant officials regardless of background.

Kenyan environmentalist Wangari Maathai received the Nobel Peace Prize in 2004 for her contribution to sustainable development, democracy, and peace. She founded the Green Belt Movement in 1977, which mobilized poor rural women to plant trees, restore degraded land, and improve local livelihoods. Under her leadership, the movement planted over 51 million trees across Kenya. She was also the first woman in East and Central Africa to earn a doctoral degree.

China produces approximately 50-55% of the world's steel output annually, making it by far the dominant force in global steel markets. This massive production capacity fueled China's rapid urbanization and infrastructure boom. However, it has also led to global trade tensions, particularly with the US and EU, over dumping concerns and unfair subsidies.

Despite spanning approximately five geographic time zones, China uses a single standard time — Beijing Standard Time (UTC+8). This was imposed in 1949 after the founding of the People's Republic to promote national unity. As a result, in western regions like Xinjiang, the sun may not rise until 10 AM and set as late as midnight in summer.
