Друзья, ПРОВЕРЬТЕ, пожалуйста, текст на английском языке! Спасибо!!

В целом все хорошо. В нескольких местах только изменил немного грамматику и термины – как мне показалось более уместным. Удачи!

There are about 100 thousand of pigmies in Zaire today. Mbuti are pygmies who live in the East of the country and speak the Efe language.
They lead peaceful life though a lot of people consider them to be merciless hunters.
Mbuti come from the forests of Ituri. They are the most typical representatives of the Pygmies of equatorial forest. They are short (no more than 4 and 1 / 2 ft.) and have light color of the skin which helps them to move in the forest shadows easily and without being noticed.
Their economy requires minimum technology. It is still at the level of the Stone Age, though they are not using stone tools yet.
They do not keep domestic animals, and do not cultivate plants living in harmony with the forest. Mbuti's ration includes mushrooms, roots, fruits, berries and nuts. Hunting is a form of their social organization. The size of each group depends on availability of food and edible plants.
