Biodiversity is the variety of plants and animals living on Earth, carefully playing an important part in maintaining the balance of nature.
The diversity of species is not distributed throughout planet because life depends on many factors including geography.
There are thousands upon thousands of plant and animal species on earth. They are all continuously evolving and adapting to the environment around them. Biodiversity is the variety of animals and plants found on this planet including the geographic locations they are found in. This concept is what makes our planet different from others in our solar system and being able experience all these variations first hand is what makes the earth so marvelous.
Think of the earth as a perfectly tuned machine with sprockets, springs, and oil (plants, animals and climates) all working to maintain the balance of nature. The diversity of species is not evenly distributed throughout the planet because life depends on factors such as temperature, altitude, precipitation, soil, the presence of other species and geography, since tropical regions support more life than polar regions.
Biodiversity is important to sustaining life on earth because it prevents any one species from throwing the balance of nature out of order. For example, snakes are not a welcome presence in our lives. We fear them and kill them because of it. One of the many things that snakes feed on is rats and if we were to kill of all the snakes, we would end up having a terrible rat problem. Therefore humans should to everything in their power to conserve the natural variation of snakes to ensure it doesn’t get an unnatural rat problem.
