Activity 3.3.3 – My Plastic Use

Image
31What are Microplastics? What are microplastics? Microplastics are tiny pieces of plastic less than 5mm in diameter. Therefore, many of these microplastics can only be seen through a microscope. Due to their widespread presence, microplastics are a major form of pollution and a real problem for us and our environment. Where they are found? Little did we know nearly everything we touch consists of some form of plastic. Microplastics are found everywhere in our homes, the water we drink, landfills, our environment, the ocean, marine life, humans, animals, and much more. These come from a variety of sources.  There are two microplastic categories, primary and secondary. Primary plastics are intentionally made small for commercial use such as the products we use every day . The plates we eat on, the toothpaste we use, hair products, clothing we wear, paint, and various other everyday items we use. The next category is secondary plastics which happens when larger plastics break down...

Activity 3.3.1 Air Pollution Core Activity

 What is Air Pollution? There are various forms of Pollution and air pollution is one of the most common ways pollution occurs. This occurs in many ways some are from natural sources and others are from human activity which is known as gaseous air pollution. Some human activity that causes air pollution are industrial facilities and motor vehicles. Natural occurrences examples can be volcanoes and forest fires. This type of pollution can cause severe damage not only to the environment but also to us. Causes climate change, habitat degradation ozone depletion along with many illnesses and diseases that can potentially lead to death.   Three gaseous air pollutants Sulfur pollutants SO2 also known as Sulphur dioxide is a common air pollutant. Sulfur pollution occurs in both natural and human activity. Some of the ways this happens is from volcanos, and fossil fuel combustions such as the burning of oil, coal, and gas that contain sulfur. You can detect sulfur in the air a...

Activity 3.2.3 – Alternative Energy

     Alternative energy is an energy source supplied from renewable resources and not fossil fuels commonly known as renewable energy. These sources include solar, wind, biomass, hydroelectric, and geothermal energy There are many pros to switching to alternative sources a major one is that it will reduce environmental impact and pollution from the use of fossil fuel energy. These resources are inexhaustible which is beneficial, especially with the increase in energy usage.      Solar energy is energy from the sun converted to heat or electricity for our usage. The sun's energy is one of the renewable resources that has been used for centuries and is widely expanding. There are two types of solar energy we learned which are passive and active solar power. Passive is used for heating and cooling in a more natural sense. Manipulates the sun's energy to give off heat such as south-facing windows to absorb heat. Whereas active solar power harnesses the sun...

Clean Coal? Myth or Reality.

       Often times when we see the word clean we think of something pure, uncontaminated, not damaging. Such as the term "clean living" we think of healthy living. On the internet you see many people trying to remove products from the shelf such as baby products that contain cancerous ingredients or snacks that contain red 40. Would you label these items "clean snacks" because they are 10% less harmful to our bodies than another brand? Therefore can something be labeled clean if its still harmful?      When you think of clean energy what comes to mind? For me, clean energy includes solar energy, wind power, and bioenergy. Did "clean" coal cross your mind? Of course not because the term clean coal is misleading. How could something be labeled clean but have negative effects on the environment? Some of the negative effects are " water and air pollution, occupational hazards due to exposure of workers to pollution, high risk of developi...

Activity 3.2.1 – Natural Resources Review

Image
      E verything around us is raw materials. The clothes you wear, the water you drink, and the fuel you use are natural resources or come from one. A natural resource is anything people take from the environment and use. ( Jerome, Brian. "Exploring Natural Resources"2017 )  Natural resources  are separated  into two groups  which  are non-renewable and renewable resources.      Non-renewable resources are unsustainable resources that  cannot be replenished  at the same pace as consumption. Once these substances  are  used  they can take up to several or thousands of years to be replaced. Many non-renewable resources are fossil fuels  which   are used  to create energy. Some examples are coal, natural gas, oil, and minerals. The second natural resource is renewable resources. There is a wide range of renewable resources, such as water, the sun, wind, vegetables, and trees. These resources can...
