Hey Readers,
Welcome to your comprehensive guide for acing Unit 8 of your APES exam! In this article, we’ll dive deep into the complexities of aquatic and terrestrial pollution, ensuring you’re equipped with the knowledge you need to conquer this challenging exam. So, grab a cuppa, get comfy, and let’s dive in!
Aquatic Pollution: From Toxic Tides to Marine Devastations
Causes of Aquatic Pollution
Aquatic pollution occurs when harmful substances enter water bodies, disrupting their delicate balance. Human activities, like industrial waste discharge, agricultural runoff, sewage overflows, and plastic litter, contribute significantly to this environmental crisis.
Consequences of Aquatic Pollution
Polluted waters pose severe threats to marine life. Contaminants can accumulate in the bodies of fish and shellfish, making them unsafe for human consumption. Toxins from algal blooms, caused by nutrient-rich fertilizers, can also lead to fish kills and shellfish poisoning.
Terrestrial Pollution: From Soil Contamination to Airy Perils
Sources of Terrestrial Pollution
Terrestrial pollution involves the contamination of soil and air. Industrial activities, mining, deforestation, and urbanization are major sources of pollutants that damage ecosystems and human health.
Impacts of Terrestrial Pollution
Soil contamination by heavy metals and toxic chemicals can inhibit plant growth and disrupt nutrient cycles. Air pollution, caused by vehicle emissions, industrial gases, and agricultural practices, poses severe respiratory and cardiovascular risks to both humans and wildlife.
