Final answer:
Ozone depletion leads to increased UV radiation which can cause skin cancer and eye cataracts in humans, disrupt growth and photosynthesis in plants, and harm marine life by disrupting ocean food webs.
Step-by-step explanation:
The depletion of the ozone layer has serious consequences for life on Earth. The ozone layer serves as a protective shield, absorbing most of the sun's harmful ultraviolet (UV) radiation. When the ozone is depleted, increased levels of UV radiation reach the Earth's surface, leading to a range of adverse effects.
For Humans
The increase in UV radiation can lead to higher incidences of skin cancer and eye cataracts in humans. It also weakens the immune system, leading to an increased vulnerability to infectious diseases.
For Plants
Plants are sensitive to UV radiation, which can disrupt their growth, photosynthesis, and nutrient cycling. This has implications for agriculture and natural ecosystems.
For Marine Life
Marine ecosystems, particularly the phytoplankton at the base of the ocean food web, are negatively impacted by higher UV levels. This can disrupt ocean food webs and harm fish populations relied upon by humans for food.
