Now, onto idea that sustainable development can work for this environment and entire planet. You have many people all ready starting to see impacts we have on environment. There are many groups and businesses and governments, which are working towards this goal. The groups are working to get politicians to bring about more regulations and laws to help protect natural environment and entire planet.

By starting with smaller portions of human population such as communities and cities, we can slowly work towards sustainable states and countries and eventually entire planet. Some businesses are helping by means of recycling, using less resources, cutting pollution and a host of other environmentally sound practices.

The United States is one of fore runners in this struggle, to change way humans interact with natural environment. More and more political leaders are stepping up to plate and doing their part to bring about positive change. Recently President Bush unveiled plans on reducing global warming and pollution, which is first meant to stop these effects and then reverse them.

Sound scientist are stepping up and reporting on sound scientific facts about environmental issues such as greenhouse gases, pollution, El Nino and any other environmental conditions, that are destroying our natural environment, which in turn will lead to destruction of our entire planet.

As more people are educated to what is happening to natural environment and learn that we humans of this planet are ones responsible for depletion and destruction of natural environment, then that is more people who will help in struggle to maintain and fix what has happened and sustainable development will become a complete reality.

One of main concepts of sustainable development that must be understood and practiced by every human is stewardship, because like it or not we are stewards of entire planets environment.

The impact of sustainable development working is that businesses will continue to function and grow and they will have customers to buy their products and resources to produce them. The impact of sustainable development working for environment is obvious. If we inhabitants of this natural environment take care of it, natural environment will continue to take care of us and we will not perish or have to move to another planet.

Instead of asking if sustainable development will work or not we need to look at facts of do we need it to work or not. I believe that it has been shown that we have no choice in this matter we either make sustainable development work or we will perish from our own lack of effort and humanity will be no more.

"Oh. That's a relief."

"But lids are not same. The yogurt top is a number 4, whereas margarine top is a number 2."

"You mean lids are not made of same plastic as containers?" my wife exclaimed.

"Exactly," I replied. "And not same as each other. There must be a reason they use for yogurt top a plastic of such poor upbringing that our recycling program rejects it. It might be dangerous to mix them up."

"That's silly."

"Then why else would they need three different plastics for two simple containers that are used for essentially same purpose under same conditions?"

My wife turned around to leave. "Wait," I cried. "There's more."

"I was afraid of that."

"The parfait container has no number. Does that mean it's undercover? The lid is a 4, which means we can switch it with yogurt lid, but not with margarine lid."

"The parfait container is clear. You can see through it. Maybe they can't recycle see-through plastics."

"Exactly what I thought," I exclaimed. "But look at your shampoo. It's in a clear bottle, a number 1. But matching conditioner, which is not clear, is in a number 2."

"That makes sense," my wife assured me. "Maybe."

"Not really. Number 2 is used in margarine lid, big ice cream bucket and vitamin jar. Besides, here is another margarine container made of clear plastic, and it is also a 5 with a 4 lid."

"This is way too confusing," my wife said. "We have a baby to attend to. She just can't seem to sleep."

"With all our containers mixed up like this, who knows what world is coming to," I cried. "No wonder she can't sleep."
