The variety of life on Earth, its biological diversity is commonly referred to as biodiversity. The number of species of plants, animals, and microorganisms, the enormous diversity of genes in these species, the different ecosystems on the planet, such as deserts, rainforests and coral reefs are all part of a biologically diverse Earth. Appropriate conservation and sustainable development strategies attempt to recognize this as being integral to any approach. Almost all cultures have in some way or form recognized the importance that nature, and its biological diversity has had upon them and the need to maintain it. Yet, power, greed and politics have affected the precarious balance.
Why is Biodiversity important?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play.
For example, a larger number of plant species means a greater variety of crops; greater species diversity ensures natural sustainability for all life forms; and healthy ecosystems can better withstand and recover from a variety of disasters.
Loss of Biodiversity and Extinctions
It has long been feared that human activity is causing massive extinctions. Despite increased efforts at conservation, it has not been enough and biodiversity losses continue. The costs associated with deteriorating or vanishing ecosystems will be high. However, sustainable development and consumption would help avert ecological problems.
Coral Reefs
One type of ecosystem that perhaps is neglected more than any other is perhaps also the richest in biodiversity—the coral reefs.
Coral reefs are useful to the environment and to people in a number of ways. However, all around the world, much of the world’s marine biodiversity face threats from human and activities as well as natural. It is feared that very soon, many reefs could die off.
Biosafety Protocol 1999-2000
The February 1999 Biodiversity Protocol meeting in Colombia broke down because USA, not even a signatory to the Convention on Biological Diversity, to which the protocol is meant to be part of, and five other countries of the "Miami Group" felt that their business interests were threatened. The safety concerns were unfortunately overridden by trade concerns. Some technological advances, especially in genetically engineered food, have been very fast paced and products are being pushed into the market place without having been proven safe. All over the world, concerned citizens and governments have been trying to take precautionary measures. However, 1999 was not a successful year in that respect.
A Biosafety Protocol meeting was hosted in Montreal, Canada January 24 to January 28. Compared to the fiasco of the previous year, this time, there had been a somewhat successful treaty to regulate the international transport and release of genetically modified organisms to protect natural biological diversity. However, there were a number of important and serious weaknesses too.
Environmental Issues
Environmental issues are also a major global issue. Humans depend on a sustainable and healthy environment, and yet we have damaged the environment in numerous ways. This section introduces other issues including biodiversity, climate change, animal and nature conservation, population, genetically modified food, sustainable development, and more.
