Climate change has profound impacts on air and water quality, posing significant challenges to environmental health and sustainability. Rising global temperatures intensify the frequency of extreme weather events, such as hurricanes, floods, and droughts, which disrupt natural ecosystems and water systems.

Renewable energy refers to energy sources that are naturally replenished over time and are sustainable for long-term use. These include solar, wind, hydro, geothermal, and biomass energy. Renewable sources are environmentally friendly, producing little to no greenhouse gas emissions, which makes them essential in combating climate change and reducing environmental degradation

Clean, renewable, and green energy are closely related concepts that represent the shift toward more sustainable and environmentally responsible energy systems. Clean energy refers to energy sources that produce little to no pollution or greenhouse gas emissions, helping to protect air quality and reduce the impact of climate change.

Solar energy is one of the most abundant and sustainable sources of renewable energy, harnessed directly from sunlight using technologies such as photovoltaic (PV) panels and solar thermal systems. It offers a clean and eco-friendly alternative to fossil fuels, significantly reducing greenhouse gas emissions and dependence on non-renewable resources.

Marine pollution is a growing environmental concern caused by the introduction of harmful substances into oceans, including chemicals, oil spills, sewage, and plastic waste. Among these, plastic pollution has become one of the most serious threats, affecting marine life, ecosystems, and even human health.

Hydrology is the scientific study of water, including its distribution, movement, and properties on Earth. It examines processes such as precipitation, evaporation, infiltration, and surface runoff, helping us understand how water cycles through the environment.
