CAIRO – 11 April 2022: Half of the world’s beaches are subject to erosion by 2100 due to waves, tides, drainage, and convection. The phenomenon threatens the safety of the planet and the disappearance of many cities, according to a recent study by the European Commission Joint Research Center.

Wildlife will be endangered, and many cities will be vulnerable to storms. The costs of measures to protect the people and wildlife will be high, which requires governments to expedite plans to mitigate the effects of climate change and limit the erosion of these coasts.

The following are four ways countries may take to slow the erosion down:

1 – Grow Mangrove trees

A mangrove tree grows in shallow sea and ocean waters, holds back 75 billion tons of carbon, can store 10 times the amount of carbon per acre compared to wild forests, and shelters marine life, animals, insects, and birds. It also acts as a buffer zone that protects the land from wind and wave damage.

2 – Green concrete

It is made of recycles materials and by products of iron and steel factories. It produces fewer amounts of carbon emissions and has environmentally friendly tiles and panels with holes and cracks that shelter marine organisms.

3 – Bio-cement

It is made of sand, bacteria, and urea. It resembles limestone and reduces the impact of breakwaters on the environment while protecting beaches from erosion. It also produces one third of the carbon dioxide produced by regular concrete.

4 – Seaweed

Creating seaweed fields under the water would protect the coasts from raging waves, help sediments transported by seawater to accumulate on the sea floor, slow marine currents, and provide shelter for marine life.
