When you consider the sheer volume of animal and plant species in the world, from the tiniest single-celled organisms up to the most massive sequoia trees and blue whales—it’s hard not to be amazed by our planet’s biodiversity. And when you consider how all this diversity both supports and is supported by its myriad ecosystems, it’s even more astounding. But what is biodiversity, exactly? And why is it important to preserve it?
What Is Biological Diversity?
The United Nations describes biological diversity as “the variety of life on earth. . . . It is the combination of life forms and their interactions with each other and with the rest of the environment that has made Earth a uniquely habitable place for humans.”
Why Is Biological Diversity Important?
The vast number of species and amazing variety of plants, animals and microorganisms in our world are important for many reasons, including “us.” The fate of humanity is tightly linked to biological diversity, and a large number of supplies essential for human life depend on it, such as:
In addition, people depend on biological diversity for their livelihoods, especially in such economic sectors as agriculture, forestry, fisheries and tourism, among others.
Biological diversity also helps to regulate climate, absorb carbon dioxide, control flooding, pollinate crops, purify water and stop erosion. But we have a problem.
Biodiversity Is on the Decline
According to PopulationMatters.org, human development is causing biodiversity to decrease in both extent and variety. Factors such as habitat loss, deforestation, resource exploitation, urbanization, intensive agriculture, pollution and invasive species are all combining to have a devastating impact.
As reported by CNN.com, for example, the World Wide Fund for Nature estimates the number of species in our wildlife population has decreased by 52% overall from 1970 to 2010. But there is hope.
What Can We Do?
Though we have good reasons to be alarmed about the problem of shrinking biodiversity, there is still a lot we can do. You can read and share blogs like this one, and educate your family about the problem and solutions. Be aware of your own impact on the environment and help turn the trend around. Every small, conscious choice will help.
Create awareness around you. Share this video from 2010 International Day of Biodiversity with friends and family.
Buy wood and wood products that come from a sustainable legal sources. Look for the Forest Stewardship Council (FSC) label, and if you don’t see it, then ask.
Reduce your paper consumption and use recycled paper. Using 100% recycled paper saves 24 trees per ton of paper!
Choose sustainable fish, avoiding endangered species, like Bluefin Tuna or certain varieties of cod. Look for seafood labeled with the blue MSC (Marine Stewardship Council) logo.
If it’s made from the skin, fur, bone, shell, beak or hooves of an endangered species, don’t buy it.
Shop local to help reduce the environmental effects of transporting food.
Take your bike whenever you can.
Remember the 5 R’s: Reduce, Reuse, Recycle, Repurpose, Refuse.
By halting the loss of biodiversity, we’re investing in all of us!

One thing we also need to stop doing is using herbicides and pesticides….that is destroying our biodiversity as well. When you can, buy organic or naturally raised, plant your gardens with heritage seeds if possible and then harvest and “bank” the seeds from the plants for next year.
My family buys organic and we will be looking for heritage seeds when we plant our garden this weekend 🙂
Buy organic and grass fed meats/poultry and support local businesses that also do farm-to-table.
Great ideas. I would love to see pesticides banned.
I recommend joining a local conservation or native animal rescue project in your area.. that’s what got me and my family interested in building bat boxes and planting butterfly friendly flowers!!
I wish there were more people interested in reducing their bad habits and help biodiversity to improve.
People seem to be getting more clued in about the environment. A lot dont realise how important it is.
