Global warming

Coral Reefs

Coral reefs are dying due to multiple threats, including climate change, pollution, overfishing, and destructive fishing methods. Rising sea temperatures trigger coral bleaching, a process where corals expel the algae that provide them with nutrients and color, leaving them weakened and vulnerable. Ocean acidification, caused by increased CO₂ levels, interferes with coral growth and reproduction.

Pollution from agricultural runoff, sewage, and plastic waste degrades water quality and harms coral health. Overfishing disrupts the delicate balance of reef ecosystems, while destructive practices like dynamite fishing physically shatter coral structures. Together, these pressures pose a serious risk to the survival of coral reefs around the world.

What can be done to change our daily lives to improve and change some activities that can help reduce global warming?

In this video, I will cover different topics that are known to be affecting our beautiful planet, and in so doing, we can: as one people, make a change, for the future Generation to come:

Radioactive Decay of Isotopes:    

 Radioactive isotopes, primarily uranium-238, thorium-232, and potassium-40, contribute significantly to the heat in Earth's core. These isotopes undergo radioactive decay, a process in which unstable atomic nuclei lose energy by emitting radiation. As they decay, they release heat, which contributes to the overall thermal energy of the Earth's interior. This heat helps maintain the molten state of the outer core and drives mantle convection, which in turn fuels plate tectonics and volcanic activity. The continuous decay of these isotopes ensures a steady supply of heat, playing a crucial role in the dynamic processes that shape our planet earth geology over time.

In this emotional and eye-opening video, I share the heartbreaking reality of how human actions are silently reshaping our oceans. From chemical pesticides used in agriculture to the unchecked dumping of plastic into drains and rivers, our world’s pollution is feeding a dangerous chain reaction. French algae, once a natural part of the sea, now thrive unnaturally due to these pollutants. This overgrowth leads to the formation of dead zones, lifeless areas in the ocean where barnacles multiply rapidly. Their growing presence now clings to and threatens beloved marine animals like whales, dolphins, turtles, crabs, and the ocean’s delicate balance. Above ground, pesticides aren’t just poisoning the soil—they are wiping out butterflies and bees, silencing the wings of pollinators we depend on for food and life.

Global warming is more than rising temperatures; it’s a slow unraveling of Earth’s delicate systems, especially in our oceans. As the planet heats up, the sea responds in ways that are both subtle and catastrophic.

One key change is in salinity, the saltiness of seawater. Melting glaciers and increased rainfall dilute ocean waters, especially near coastlines and polar regions. This shift in salinity disrupts ocean circulation, which depends on the balance between temperature and salt to drive currents. These currents regulate climate, transport nutrients, and support marine life. When salinity changes, the cycles and even tides of the oceans globally can be affected.

Coral reefs, the vibrant cities of the sea, are among the first to suffer. Warmer waters cause coral bleaching, where corals expel the algae that give them color and life. Without these algae, corals starve and die. Lower salinity and increased acidity further weaken their skeletons, making them more vulnerable to storms and disease. Entire reef ecosystems collapse, threatening the thousands of species that depend on them. Although this is a slow change over the years, the impact could reach to a point where there is no going back.

Beyond reefs, global warming affects oxygen levels, nutrient flow, and the migration patterns of fish. Warmer, less salty water holds less oxygen, creating dead zones where marine life cannot survive. These changes ripple outward, affecting fisheries, coastal communities, and global food security.

The ocean is Earth’s heartbeat. When its chemistry shifts, the consequences reach every shore. Protecting it means reducing carbon emissions, preserving coral habitats, and understanding the quiet signals. Like salinity, it warns us of deeper change that can impact our global ecosystems, both sea and land.
