New York City faces a big problem. The ocean is getting higher and storms are stronger. This brings a lot of water into the city.
The water can go into streets, subways, and homes. This is a serious threat for the people who live there. The city needs a good plan.
One idea is to build large walls to protect the city from the ocean. These walls can stop the water during a big storm. It is a very big job.
Another solution is to make more green spaces, like parks. Parks can hold the extra water like a sponge. This helps keep the city safe.
