Human activities have a big impact on our coastlines. Here’s how they affect coastal features and processes:
City Building: When people build cities near the coast, they often take away natural barriers. About 40% of people in the world live less than 100 kilometers (about 62 miles) from the coast.
Pollution: Coastal waters get dirty due to pollution. It's estimated that 80% of the trash in the ocean comes from land.
Erosion and Sand Supply: When we build dams, it stops sand from flowing to the coast. This can lead to up to 70% more erosion in some places.
Climate Change: Sea levels are rising because of climate change. By 2050, about 23 million people in the UK could be at risk due to higher sea levels.
