Environmental Challenges Quiz

Environmental Challenges Faced by the World Today

• Industrial and transportation toxins, plastic, oil spills, acid rain, and urban waste are causing depredation and defiling of the sea, rivers, and water beds.
• Global weather pattern changes, extreme snowstorms, the spread of deserts, and ocean and land temperature surge leading to a rise in sea levels.
• Overpopulation is one of the biggest environmental challenges faced by the world today.
• The exhaustion of the world’s natural non-renewable resources from oil reserves to minerals to potable water.
• A waste disposal catastrophe due to excessive waste unloaded by communities in landfills and oceans, including nuclear waste.
• Destruction of million-year-old ecosystems, loss of biodiversity, deforestation, and extinction of particular species.
• Reduction of oxygen and the increase in carbon dioxide in the atmosphere because of deforestation, leading to the rise in ocean acidity.
• Depletion of the ozone layer due to chlorofluorocarbons (CFCs) in the atmosphere.
• Deadly acid rain due to fossil fuel combustion, toxic chemicals from erupting volcanoes, and rotting vegetables in garbage dumps.
• Water pollution arising from industrial and community waste residues seeping into underground water tables, rivers, and seas.
• Urban sprawls that continue to expand, destroying farmlands, increasing traffic gridlock, making smog cloud a permanent urban fixture.
• Pandemics and other threats to public health arising from wastes mixing with drinking water, polluted environments, and pollution.

Man-made Pollution:

• Sandstorms and combustion exhaust from traffic and industrial waste have made Riyadh one of the most polluted cities in the world.
• Coal fumes from industries have contaminated 20% of China's soil, threatening the food supply.
