Biodiversity for life
Life is what makes the Earth go round, literally. Even as we search for life on
Mars, Titan and worlds beyond, we are yet to understand completely the sheer
variety of life on Earth itself. This is called Biodiversity. Biological
diversity - or biodiversity - is the term given to the variety of life on Earth
and the natural patterns it forms.
The biodiversity we see today is the fruit of billions of years of evolution,
shaped by natural processes and, increasingly, by the influence of humans. It
forms the web of life of which we are an integral part and upon which we so
fully depend. Biodiversity also includes genetic differences within each species
- for example, between varieties of crops and breeds of livestock. Chromosomes,
genes, and DNA-the building blocks of life-determine the uniqueness of each
individual and each species. Biodiversity is the foundation for life and for the
essential services provided by ecosystems.
Variety
Sri Lanka itself is a biodiversity hotspot, with a huge variety of endemic flora
and fauna. As we have seen, biodiversity underpins peoples’ livelihoods and
sustainable development in all areas of activity, including economic sectors
such as agriculture, forestry, fisheries and tourism. If we can halt the loss of
biodiversity, we can focus more on investing in people, their lives and their
well-being.
Today, which happens to be the day following Vesak, is also the International
Day of Biological Diversity. The Buddha was a great religious leader who stood
for the right to life of all living beings and it is rather fitting that the two
events have coincided. Buddhism espouses compassion towards all living beings
and in ensuring biodiversity, compassion plays a central role. For example, if
people stop killing certain exotic animals for their body parts, biodiversity
will increase.
The United Nations General Assembly, on 20 December 2000, proclaimed 22 May as
The International Day for Biological Diversity, to increase understanding and
awareness of biodiversity issues. The date designated for the day was chosen to
commemorate the adoption of the text of the Convention on 22 May 1992 by the
Nairobi Final Act of the Conference for the Adoption of the Agreed Text of the
Convention on Biological Diversity.
Created
The day was first created by the Second Committee of the UN General Assembly in
late 1993, and the UN General Assembly, designated December 29th (the date of
entry into force of the Convention of Biological Diversity) the International
Day for Biological Diversity. However, it was difficult for many countries to
plan and carry out suitable celebrations for the date of 29th and it was shifted
to May 22.
The day’s activities will continue to the thirteenth meeting of the Conference
of the Parties to the Convention on Biological Diversity (COP 13) to be held in
Cancun, Mexico from 4 to 17 December 2016. It will focus on the mainstreaming of
biodiversity within and across sectors, which is closely linked to this year’s
IDB theme.
This year’s theme is “Biodiversity, Sustaining Life on Earth”. Indeed, it is
variety of life that sustains the Earth. Biodiversity is an important issue in
the 2030 Agenda for Sustainable Development. Goal 15 explicitly recognises the
importance of halting biodiversity loss, and other Goals recognize the
importance of biological diversity for eradicating poverty, providing food and
fresh-water, and improving life in cities.
Surface
We have barely scratched the surface when it comes to life on earth, especially
in the deep oceans. So far, about 1.75 million species have been identified.
Scientists believe that there are actually about 13 million species, though
estimates range from three to 100 million.
The deep ocean is the biggest and least-explored area of the planet. At depths
of up to 6,500m, it is extremely energy-deficient, yet it is home to a massive
variety of life. As scientists begin to get a better understanding of this vast
ecosystem, it is becoming increasingly apparent how important they are to the
rest of the planet. Millions of species on land and in the water are waiting to
be discovered and named. Each species is important in the circle of life, though
some are of critical importance. For example, if the bees were to vanish
tomorrow, the Earth would probably be devoid of most forms of life in a decade
or so. Thus, there is a lot more to learn about life on Earth.
Species
Even as we find new species, certain existing species are vanishing at an
alarming rate, according to the International Union for the Conservation of
Nature (IUCN) Red List. Some species (both flora and fauna) are down to only a
few individuals who are at a reproductive age. For example, environmentalists
warned last week that the vaquita marina, the world’s smallest porpoise endemic
to Mexico, is on the brink of extinction. The Mexican government reported that
only 60 are now left in the wild. With the recent spate of killings, the Sri
Lankan leopard is also facing difficult times ahead.
Nearly 80,000 plant species out if 391,000 listed in a recent Royal Botanical
Gardens (RBG) study report are facing extinction. The comprehensive global
assessment of the state of world’s plants, published on May 9, has been carried
out by over 80 scientists attached to the RBG Kew, the IUCN, and the Natural
History Museum.
Consume
We do consume some biological resources, such as trees and animals including
fish. But what would happen if we harvest fish without controls or limits? There
will be no seafood left for consumption in a few years. In fact, unsustainable
consumption continues even as demand for resources worldwide exceeds the
biological capacity of the Earth by about 20 percent. This is an alarming
situation that has to be contained.
The good news is that more countries are starting to take notice. One of our
South Asian neighbours, Bhutan, recently became the first country to meet calls
for “nature needs half” by setting aside over half of its land into protected
areas and biological corridors under its “Bhutan for Life” program.
Bhutan now has ten protected areas along with the Royal Botanic Gardens of
Lamperi located an hour outside the capital Thimphu which is probably the only
botanic garden in the world where wild tigers roam. This is exactly the type of
initiative that we need to stave off further loss of biodiversity around the
world. |
