​Biodiversity, or Biological Diversity, is the variety of forms of life on Earth such as genes, bacteria, species, and the habitats they live in like oceans, coral reefs, forests, and deserts. Biodiversity is very important to the survival of people and all other lives on Earth because biodiversity provides not only adequate places to live, but also clean air as well as water, food, and fuel to all lives on Earth.

However, biodiversity is in danger of being lost by several factors, such as deforestation, overfishing, urban development, pollution, and climate change. Among these factors, climate change caused by the increase of Carbon Dioxide is a major factor of biodiversity loss. Around 4% of mammals can lose half of their habitats if the average temperature increases by 1.5C. This volume can upsurge to 41% if the temperature increases by 3C. Meanwhile, 70 to 90% of all coral reefs can be vanished by an 1.5C increase of temperature, while 99% of coral reefs can disappear with 3C increase.

The impact of biodiversity loss can be much severe than many people might anticipate. There can be a spike of infectious diseases by biodiversity loss, since the origins of around 60-75% of human infectious diseases,such as M-pox, Covid-19, AIDS, Ebola, Lyme disease, dengue fever, and Zika, can be traced back to zoonotic spillover. There can be an increase of conflicts between wildlife and humans. And, the food security of many countries and exacerbate because of unstable food supplies that biodiversity loss can bring.
