Every single time you breath, you inhale 1% of other substances. Instead of expressing 0.0393 molecules of carbon dioxide per 100 molecules in the air we would say ppm (parts per million). Some of the substances found in concentration are air pollutants. In major cities humans leave activities leave “air prints”. When large amounts of people cook and drive vehicles, they are basically dirtying the air. We focus on four gases that contribute to air pollution. Carbon monoxide, ozone, sulfur dioxide, and nitrogen dioxide. Carbon monoxide is the only odorless one out of the four. Ozone, Sulfur dioxide, and nitrogen dioxide all have characteristic odors. Ozone has a share odor that detected around electric motors or welding equipment. Sulfur dioxide has a sharp, unpleasant odor. if you inhale Sulfur dioxide it dissolves in the moist tissue of your lungs. Nitrogen dioxide has a characteristic brown color. It can combine with moist tissue in your lungs and form to acid too. Lastly particulate matter is a complex mixture of tiny particles and microscopic liquid droplets. The pollutants all have the same hazards.
What we Breath. Adults usually breath more than 11,000 liters. The air we breath is nit a single substance, it is a mixture. The air that we breath is more like 78% nitrogen, 21% oxygen, and 1% other substances. Nitrogen is the most consistent substance of what we breath. But even Oxygen is not as sufficient it still plays a key role. Oxygen is the most abundant element in the human body mass. Every time we exhale, we release carbon dioxide in to the earths atmosphere. There are many other gases that are in our atmosphere. There are many things that we breath in and out but nitrogen and oxygen is what we mainly breath in and carbon dioxide is what we breath out.
Cradle to grave means thinking about every step in the process. Not only should companies take responsibility so should the people. Instead of using the plastic bags, bring your own bags from home. In the end when you are using the plastic bag to bring stuff home you could be using a bag from home that is reusable. This is basically about how you can use the same things over again instead of wasting plastic.
The Average U.S. citizen ecological footprint in 2007 came out to be about 8.0 hectares or 20 acres. That basically means if you live in the U.S. you take up about 8.0 hectares. The world average in 2007 was estimated to be about 2.7 hectares not 8.0. Currently there is about 12 billion hectares of land, water and sea surface. That turns about to only be quarter on the earth surface. Also this means we are way over the amount of hectares a human should be using. Therefore we need to find ways to lower the amount of hectares.
Everyone has a job as a human. we need to take care of our planet. One way we could help our planet is Green Chemistry. Green Chemistry is the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances. If we did this, it would lead to cleaner air, water, and land. There are many ways to lower problems but this could make a huge impact.
In the beginning, the article talks about how to motivate students to get better grades. Could intelligence be something inherited or something developed? Alfred Binet says that children’s intelligence could be transformed and enhanced through education. Also in the article it says that while the work load increases the grading becomes more stringent, and the environment becomes less nurturing. If the children came into scroll with the mindset saying that they are going to work hard, it is most likely for them to get a higher grade than others that don’t. Students that tend to get bad grades usually don’t that the motivation to make an improvement. its all in the students head. This is because when you say you can’t do something in you head you won’t be able to succeed for your goal. Student usually lack motivation don’t get the grades that should be getting. It clearly states in the article that when you receive intelligence praise, the adopt to a new and more successful mindset. This article is basically about how more motivation when it comes to school will help you get better grades an have a better mindset going forward in the years.
In the reading 0.2 talks about what we could do for currently that could help us in the future. It talks about us, humans making a sustainable world. Also it talks about what are sustainable choices and what are not. For example, in the reading it says that fossil fuel are non-sustainable for the world. People are working on making a sustainable world by setting goals. Day by day, people are working on making the world better with four main targets. From the reading it says, “Preserving the habitability of the Earth and its ability to provide the resources required for future generations to thrive is a basic human obligation”. That is saying the future people need to also work on making the world a more sustainable place so when they are living it won’t be a big as a problem. In 0.3 the main idea is the Triple Bottom Line. Which is benefits to the economy and environment. It talks about how the economy and how it needs must be healthy and its annual reports must show signs of profit. This is basically saying that it doesn’t only take humans to make a better world but also the environment. As a result, everything we do in life effects our life and the earth.
