Conserving Nature to Protect our Health

Conserving Nature to Protect our Health

Brent McCreesh is a happy, healthy second grader, but if he were born 10 years ago he might not have even made it to preschool. Brent was diagnosed with neuroblastoma – an aggressive cancer — when he was just 2 years old. Thanks in part, however, to a medicine created from molecules identified in an African flower, an American mayapple tree and a soil bacterium, doctors were able to save his life.

Treatment of Brent’s cancer brought us – his mother and one of the many doctors who participated in his treatment – together. Our experience also gave us a profound appreciation for the important role nature plays in treating human disease. Now, we feel it is time to speak out on behalf of nature’s medicine cabinet, which is growing smaller every day.

Few people realize that half of all new medicines are based on chemical compounds that come from nature. This includes many treatments used for heart disease, type 2 diabetes, HIV, and other conditions that affect millions. A staggering 70 percent of all cancer drugs contain an active ingredient derived from nature.

Compounds found in a Caribbean sea sponge led to new anticancer and antiviral drugs. In Borneo, an anti-HIV compound emerged from research on the sap of a rainforest tree. A compound found in the venom of a Brazilian snake, the pit viper, is used to treat hypertension. And researchers are examining substances found in the skin of South American frogs for the possibility they may hold the key to stopping AIDS. The rosy periwinkle, a plant found in Madagascar, is the source of vincristine – a drug that was instrumental in Brent’s cancer treatment.

The places that house plants and organisms critical to the development of new drugs often lie far from the hospital or pharmacy. Most of the world’s species live outside our borders, in the forests and along the coastlines of developing countries in the tropics.

Please take action to conserve the world’s remaining natural ecosystems and species. 

And even as scientists and researchers strive to develop new and better medications from substances found in nature, we are rapidly destroying the places from where this raw material comes. An area of forest the size of Costa Rica is destroyed each year, and one-third of coral reefs are already gone. Scientists estimate that half of all the world’s species could be on the brink of extinction by the end of this century.

The United Nations Environment Programme estimates that with current extinction rates, we lose one major new drug every two years. In all likelihood, many of nature’s keys to unlocking disease are already gone. Sadly, many poor countries lack the tools and funds to protect habitat for plants and animals.

A bipartisan bill in Congress, called the Global Conservation Act of 2010, aims to protect the local branches of nature’s pharmacy all over the world before they’re put out of business permanently. It would address global extinction by establishing a U.S. strategy to help developing nations protect large areas of natural habitat. It then asks the administration to get other nations around the world, including newly wealthy countries like China and India, to work with us to help poorer countries.

Many cancer survivors like Brent recently traveled to Washington to support the bill and to tell their representatives how much natural areas in developing countries have affected their lives. While some politicians were sympathetic, some were skeptical about taking any action that could be seen as helping poor countries when we have so many needs here at home.

But one in three Americans will be affected by a disease with a treatment derived from nature. That means we all probably know someone who has or could one day benefit from these medicines.

Please join us in urging Congress to protect global species and ecosystems. 

Without medications derived from several natural areas around the world, Brent would likely not have survived his cancer. We cannot let the tools to fight diseases that affect so many of our loved ones fall by the wayside. The places we need to save may be far away, but the benefits could not possibly hit closer to home.

ty and signed, seems to be a US and Canada only petition

Wow, i didn't realize everyone didn't know that medicine comes from plants. YES THEY DO. I am a medical student and this article is the absolute truth. So thank you for spreading the word that not only are we killing beautiful areas that many creatures depend on for survival(& one less creature in our ecosystem causes a domino effect on all of us that are a part of it) but we are also killing the chance of discovering some new medicines that may be the cure to so many debilitating diseases out there. KEEP UP THE GREAT WORK! WAY TO GO BRENT!

makes sense: naturally occuring ailments being treated by remedies found in nature. That's why I really believe in chinese, herbal meds: it helps to restore balance as opposed to fighting the phenomenon. This view also makes you realize how integral our bodies are to nature as other animals are.

I'm all for remedies from nature, but if they're tested on animals where is our sense of ethics? I'd like to know whether these "cures" were trialled in laboratories on innocent animals.

We are lucky to live no matter how long and whenever. I must give science and technology a notable mention, for it is through the wisdom of others in the scientific field that helped me find reasons to live with purpose - and contribute to furthering education thereof with a touch of artful muse.

"The good is reverence for life;it is extending ourselves to uphold life, to help it endure. Evil is to destroy life, to cause suffering. To help life reach full development, the good man is the friend of all living things " Albert Schweitzer, Paris notes.
Let us respect the forests; let us be satisfied with what we have already stolen from nature and above all let us try to go up in the evolution than come down. All the incidents happening every day through the world show us how mean we are and how selfish we are and we will do anything ( steal, kill,cheat...) to increase our comforts which give happiness to our senses momentarily.

Good article!

There is probably a cure for everything somewhere in nature. That would make sense since we are part of nature and all of nature is made from the same particles.
It is a shame that in human greed for money, everything good is being destroyed and an ever increasing rate of speed.

thank you for this article.

Seems that Sean Connery was in a movie "Medicine Man" about this very issue. He played the doctor who found a cure for cancer deep in the Rain Forest, but those forests were being destroyed by developers. Humans were ensuring the end of Human civilization on this earth. Sound familiar?

thanks for the info didn't know this but also don't do bonfires.

Appreciate the information and very sad to hear of killing any wildlife with a fire. Personally, I can't…
