Biodiversity
Biodiversity means the rich variety of life forms in nature. Countless plants, mammals, insects, birds, fish and reptiles contribute to the diversity and the beauty of our planet. All animals and plants are important because each species form part of nature's biological life-cycle on which all life depends. Most of the Earth is covered by water and the bottom of the sea contains millions of species, most of which have not yet been identified.
For millions of years, plants and animals have evolved and developed into what they are now today. They have survived all these years without the threat of extinction. Unfortunately, many of them are now endangered because of human activities.
All beings form part of an ecosystem and play an important role in maintaining life on Earth. Apart from being the most important source of food for humans and animals alike, plants are used as medicine by more than 60% of the world's population.
Did you know?
- There are more species on the earth than stars in the universe!
- It is estimated that between 150 and 200 species become extinct every day.
- Governments currently spend $1 per person a year on nature reserves. At least $50 per person is needed each year to save endangered species.
- Once a species is lost it is gone forever.
Challenges
Deforestation, forest fires, pollution and agriculture all contribute to the loss of habitats and the species that live in them. Roads and railways can block natural mitigation and feeding routes.
Other causes for extinction:
- overpopulation
- over-fishing
- use of pesticides
- draining and filling up of wetlands
- pollution
- the conversion of habitats into fields or urban areas
Take action!
- We have the responsibility to act as guardians of all life on this planet: by banning hunting, conserving habitats and promoting reforestation.
- Do not purchase products such as ivory, tortoise shell, coral and reptile skin, all of which come from endangered species. Ask your parent, relatives and friends to do the same.
- Learn and inform others about the importance of biodiversity.
- Write your concern for biodiversity to the media and your local government.
