Environmental science fair projects for 20 year olds?

1. Investigating the impact of plastic pollution on marine ecosystems: This project could involve collecting water samples from different bodies of water and analyzing them for microplastics. The student could also research the effects of plastic pollution on marine life and propose solutions for reducing plastic waste.

2. Studying the effects of climate change on local ecosystems: The student could choose a specific ecosystem in their area, such as a forest or wetland, and research how climate change is impacting the plants and animals that live there. They could also propose ways to mitigate the effects of climate change on the ecosystem.

3. Analyzing the environmental impact of different types of transportation: The student could compare the carbon footprint of different modes of transportation, such as cars, buses, and bicycles. They could also research alternative forms of transportation, such as electric vehicles or public transportation, and evaluate their environmental benefits.

4. Investigating the effectiveness of renewable energy sources: The student could research different types of renewable energy, such as solar, wind, and hydroelectric power, and compare their efficiency and environmental impact. They could also propose ways to increase the use of renewable energy in their community.

5. Studying the effects of deforestation on biodiversity: The student could research the causes and consequences of deforestation in a specific region, such as the Amazon rainforest. They could also propose ways to protect and restore forest ecosystems to preserve biodiversity.
