Global Warning

The issue of Earth's climate change is really nothing new,
Joseph Fourier described "greenhouse effect" in 1824,
Despite the constant coverage, I think we could do more,
So to save the planet's future, here's what I am going to do.

Let's start with something simple, like switching off the lights,
I'll go a little further and buy the energy saving sort,
True, they're not attractive but I will not let that thwart
My newfound enthusiasm for my global warming plight.

I'll use public transport, at least once or twice a week,
So what if it adds an hour or three to my daily commute?
I'll meet fascinating people, while helping Earth to boot,
And I'll get exercise while standing when I cannot get a seat!

When I trundle home from work, no heating on for me,
Finally a use for those offensive Christmas knits!
If I'm still cold I'll don a hat and dig out my old mitts,
But  the condensation from my breath is blurring the TV!

I never knew cosmetics could cause such climate wrongs,
So I've binned my deodorant because I have deduced,
I can make a home made one from zinc-oxide and aloe vera juice,
I'll finally get some "me time" when my armpits start to pong!

No more brand new clothes for me, second-hand is the new black,
I'm recycling and stopping sweatshops using eight year olds!
I'm sure the clothes are cleaned and checked for bodily fluids and mould,
But apparently it's "not in the spirit of things" to ask for your money back!

Recycling my waste is great, though I now need multiple bins,
I wonder how much C02 was produced to manufacture those?
But recycling rules are quite complex and it nearly came to blows,
Over the council's stupid sticker saying I'd put the wrong things in!

So finally I've made the change, I'm really going green,
Plastic bags are evil and I'm knitting my own yoghurt,
I really think my efforts will reduce the planet's hurt,
I've  just one nagging little doubt on which I'm not too keen.....

My carbon footprint's nicely clad, in Birkenstocks you'll find!
And about my little doubt, let's not make a song and dance,
But what good will my efforts make when scientists cite a chance,
Of an asteroid hitting earth and annihilating all Mankind?!
