Earth Day and Science

Today is Earth Day. 


There is also a march for science happening, as people feel that science is being threatened by the current government. Along with the big march in Washington, there have been marches in cities all over the country. People are pointing out how science as helped us and how badly needed it is. 

One quote going around is: 

“The good thing about science is that it's true whether or not you believe in it.”

                                                                          ~Neil deGrasse Tyson

My personal response to that is this statement, that I posted on Facebook:

Science helps us explore the universe and our own back yards. It gives us a systematic way to observe and test what's around us. Science really isn't true or false, it helps us discover what is true or false about the physical world. It is highly important that we have people well educated in scientific method and aware of what has been learned and discovered in the past. Science and science education need to be supported. 

Science isn't something to be "believed in." It's a process (or a set of processes) which help us to learn many things. It has it's limits. It changes over time.

Put it in the context of Earth Day. Climate change is a big issue. It would be hard to say based on scientific evidence that global warming isn't real. It would also be difficult to argue that it isn't human driven. But scientists don't claim to have found out everything about this phenomenon. They are still studying, seeking causes and remedies, refining theories. Views on the specifics change all the time and vary from scientist to scientist. Also, no scientists studies all aspects of it. Some study the greenhouse effect, others melting glaciers, others the connection to increased severe weather events.

Here's another thing. Science doesn't tell us how to behave. Scientific discoveries can show us what the consequences of certain actions will be, but it doesn't offer moral evaluation. It's not meant to do that.

Science also isn't either good evil. It is how it is used that determines that. Remember scientists  have brought us both the cure for polio and the atomic bomb. Healing and destruction.

Personally, I believe that God gave us the inquiring and curious minds that have lead to the development of science. His Word can also give guidance in how to use it, to build the Kingdom of God rather than tear people down. 

Judeo- Christian culture historically supported science and allowed it to flourish. Check out more on that here: Are Christianity and Science Compatible?  There have been many clashes between science and the church, but really theology and science, if each is rightly understood can be complementary. 

One final response to Mr. Tyson's statement: 

God is real and alive and good, whether you believe in him or not. 

And that doesn't change the fact that science is important.

Mosquitos vs. Sumithrin

I have an organic garden.

Or perhaps I had one.


My town contracts for truck -based aerosol spraying of Anvil, a pesticide formulation containing sumithrin, PBO, and white mineral oil (a petroleum based solvent.)

Sumithrin is considered "slightly toxic" and both PBO and white mineral oil are minor carcinogens.

For more information:

The New York State Department of Health's information sheet on Anvil

This stuff was sprayed on my street, near my garden, the night before I intended to harvest green beans. AAARRRGGGHHHH!! I had been watching the newspaper and hadn't seen an announcement of the spraying.

I waited 24 hours before harvesting the green beans and washed them thoroughly. But I really don't want this stuff on my food. How well does it wash off?

After doing a little research, I spoke to the company contracted to do the spraying. I hear that sumithrin breaks down quickly in sunlight (but my garden doesn't get sunlight until midday.)

I learned that Sumithrin persists in soil for up to sixteen weeks. My contact agreed that to be true but said that it adheres to the soil and doesn't go anywhere for that time. Umm....except under my nails. And it's in the soil on any root vegetables or vegetables that touch the dirt in that time.

The kicker? I asked if the spraying was effective, since mosquito borne illnesses are a threat, too, after all. I got the following evasive answer. "Well, it's truck spraying. It's not aerial spraying. That would be effective, but it's politically and environmentally prohibited in [this state.]" So it sounds like these sumithrin applications aren't all that helpful.

Non-pesticide mosquito control measures include eliminating standing water on property, keeping pools clean and chlorinated, and maintaining bat houses. People can also avoid bites by staying in during peak mosquitos hours, covering up if they do go out and judiciously using repellants.

My town's board of health wanted to talk about eliminating the spraying, apparently, but the board of selectmen refused to discuss it. I guess I need to get politically active.

I have excluded my property from all mosquito spraying and town-wide pesticide applications, so by next year my garden will be fully organic again.

What are your thoughts on mosquito spraying?
Do you have any other resources on this topic?




 

More than their share...

I was chatting with a friend and he told me about some new people in his neighborhood.

It seems they have built new houses, which they use as vacation homes. These homes are generally empty, except for certain summer weekends. BUT the heat is on year round to protect the artwork they contain.

My friend's wife was an accountant. She had as a client an oil dealer who works on an island full of such second homes. He told her that when he started a few decades ago, he would take out his truck in the morning, drive around delivering oil, and then go back home for lunch at which time he would fill the truck for the afternoon run. Now, he goes to one home, delivers the oil and needs to return home to fill the truck right away, because it is empty.

That's right, he empties a whole truckload of oil at one house, at which no one is living.

Um, I had heard that we need to conserve oil and other fossil fuels. When I related this to another friend, he wondered aloud how people could justify that level of consumption.  I wonder that, too.

So, I think I might start to write more posts on conservation, as well as being careful of my own fuel use. I am not sure what else I can do to help. Environmental issues are close to my heart, but I am not hugely knowledgeable. Perhaps we can all share some ideas.

Have a good day!
