How ants changed Kenya
Big-headed ants came to Kenya’s Laikipia Plateau in the 2000s and spread quickly. They attacked many insects and birds, but the biggest problem was their fight with local acacia ants. Acacia ants live inside whistling-thorn acacia trees and protect them from animals like elephants.
The new ants killed acacia ants and made the trees weak.
Many trees fell, and the land became open grassland.

In short
This article explains how big-headed ants, an invasive species, caused big changes in Kenya. They arrived in the 2000s and quickly attacked local acacia ants. Acacia ants usually protect acacia trees from animals like elephants. When the new ants killed the acacia ants, many trees became weak and fell, turning forests into open grasslands.
This environmental change also affected lions. Lions need trees to hide and hunt their usual prey, like zebras. With fewer trees, zebras could escape more easily. As a result, lions had to start hunting buffalo, which are stronger and more dangerous animals. This story shows how even small creatures can have a huge impact on an entire ecosystem, including plants, trees, and even top predators. It's a great example to practice your English reading skills.
