Which actions can humans take to reduce wave erosion? check all that apply. build drainage systems build houses near coastlines build breakwaters in the ocean reduce vegetation along coastlines reduce effects of global warming

The correct answers are:

- build breakwaters in the ocean.

- reduce the effects of the global warming

By building breakwaters in the ocean the wave erosion will reduce, and this is because the force of the waves will be reduced. The breakwaters are set into the water with the purpose of stopping and reducing in size and power the bigger waves, and they serve as obstacles on their way. This is a very simple and very effective measure, and it is set in use in multiple places around the globe.

The reducing of the effects of the global warming will too be very helpful. The reason why this will help with the wave erosion is that the global warming is melting the ice sheets and the glaciers, resulting in a rise in the sea levels. The rise of the sea levels means that the water is moving further inland, thus causing much more wave erosion. By reducing the effects of the global warming, the sea level will not rise so quickly, so the wave erosion will be reduced as well.
