Summary Introduction

To describe:

The threats of habitat destruction, overexploitation, invasive species, pollution, and global climate change.

Introduction:

Biodiversity is a habitat where entire living organism lives together. It is of three types: species biodiversity, genetic biodiversity, and ecosystem biodiversity.

Habitat destruction, overexploitation, invasive species, pollution, and global climate change are the threats to biodiversity.

Habitat destruction occurs due to human activities like urbanization, deforestation, and overhunting; due to these activities species lose their habitat.

Overexploitation occur when humans start over harvesting the species; for example, over hunting and over fishing,

Invasive species are not native to the ecosystem and cause harm to other existing species are called invasive species; it can be anything plant, insects, or fish.

Pollution it is of many types; for example, soil pollution, air pollution, and water pollution. It is caused by humans and affects biodiversity.

Global climate change occurs due to overharvesting of species, and pollution, ecosystem starts to imbalance, which cause changes in the climate called global climate change.
