In addition, Liberian tribes are linguistically divided into three main groups, the Mande people, the Kru tribes, and the Mel.

African countries dominate the list except for Papua New Guinea. The dominance is related to the tribal culture in the country.

Here are the top three biodiverse countries in the world.

1. Brazil

Brazil is the topmost biodiverse country on this planet. From the Amazon rainforest to the Mata Atlantic forest, between the woody savanna-like cerrado and the massive inland swamp and the aquatic ecosystems, Brazil is leading the world in the plant and amphibian species counts. It holds second ranking in mammals and amphibians and third in birds, fish, and reptiles.

2. Indonesia

Indonesia has a wide array of marine ecosystems and land resources, including the third-largest rainforest and the famed Coral Triangle. The country rank on the top list of most biodiverse countries as it has most of the mammal species of any country. There are rhinos, orangutans, elephants, bears, and tigers in Indonesia, the only place on Earth where they can all live in the same forest.

3. Colombia 

Colombia ranks in the top third on the biological diversity index because of its incredible bird, amphibian, and plant richness. With over 1800 different species, Colombia has more bird species than any other country on the Earth. The biological richness in Colombia is due to its wide range of ecosystems that includes tropical forests in the Amazon and mountain habitats like the Sierra Nevada and Andes.


Thousands of languages are spoken worldwide, but only a fraction is used globally. Here are the top countries with the greatest linguistic diversity.

1. Papua New Guinea

With just an 8.8 million population, Papua New Guinea comes with 840 languages spoken all across the country. More than twice the number of languages spoken in Europe can be found in PNG alone; from here, you can imagine how much linguistic diversity exists in the country. The isolation from modern life makes the country linguistically diverse. More than 80% of the country’s population lives in rural areas and is hardly connected to the other tribes and external influences. In fact, people cannot understand each other after a few kilometers.

2. Indonesia

Diverse ethnic groups populate Indonesia, and every group has its own language. With over 270 million people, Indonesia has 712 languages spoken. It ranks second after Papua New Guinea. Likewise, PNG, a major factor that could explain the linguistic diversity in Indonesia, is its geography.

3. Nigeria

Nigeria ranks third after Papua New Guinea and Indonesia. The total population of Nigeria is over 201 million, and 522 languages are spoken in the country.

In addition, India, the United States, Australia, and China have 454, 326, 314, and 308 languages, respectively. It is very much clear that a multitude of languages still exists; over 40% of the world’s languages are endangered. Above all, we lose a language every two weeks. Even in the regions where immense linguistic diversity remains, languages are dying with each upcoming generation.

Wrap Up

Let’s wrap up the discussion with a few positive words. Diversity has both positive and negative impacts on a country or society, but the thing is, we have to respect every culture and the values and norms of all ethnic groups. In addition, we need to focus on endangered languages and need to do something to save them.
