For years the world has watched while our planet dies. We know that some of our actions harm the planet yet we continue to do them. America is supposed to be a world leader, paving the way for other countries to follow. Yet we seem to be falling behind when it comes to some aspects of protecting the environment. Not to mention that the Trump Administration is doing everything they can to put the environmental problems on the back burner. We need to take a firm stance with aiding the restoration of our planet and proving to the rest of […]

Humankind and nature has been at war. This conflict has been waging on for centuries. For the longest time, Nature had wreaked the Earth with havoc, flooding, quaking and burning. In fact, some 70,000 years ago, humans almost went extinct due to a gargantuan volcano eruption. Toba, the Supervolcano. There was enough ash, dust and vapour in the atmosphere to dim the sun’s light for a minimum of six years. The human population was reduced to about 40 breeding pairs due to a drop in global temperature, reduction of food resources and clogged up water bodies. Still, in this era, […]

EnergyConservation__ Having to know,the world is one and ours, to do whatever it takes to conserve what is given tous. A worldwide increase in energy demand, and concerns over air pollutionand global warming, have led to an urgency of clean energy and energy storage. Consideringthe needs of a contemporary civilization, the discovery of advanced, economicaland environmentally friendly energy conversion and storage system has becomeundeniably fundamental which opens gates to the widespread application ofrenewable energy sources as well as to an exploration for better energy storagesystems. Hybrids_ electricvehicles are becoming more current, playing an important role, both, for thereduction of air […]

Australia is a huge country, it is almost the world biggest country. They use many different kinds of energy such as coal, gas and sometimes hydro energy, but the top 2 are solar and wind energy. They both are renewable energy which is good to the environment. Many people are using these kinds of energy which is all renewable. Solar EnergySolar energy always comes from the sunlight. It is produced when the energy or the heat from the sun. Then, it will change into electricity that can gives your house energy or electricity to light up your house. It can […]

A Human Footprint: Pollution Threatens Earth’s BiodiversityHave you ever wondered how we, as humans, impact our environment? Take a look at any ecosystem in the world and there could be multiple types of contamination such as streams filled with toxic chemicals, rivers overloaded with nutrients that come out of farms, trash blowing away in landfills, and even city’s skies covered in smog, but here’s the thing. Among all the threats our environment face, pollution is actually the biggest one against our biodiversity and here’s why. For starters, pollution is the introduction of contaminants into a natural environment causing adverse changes. […]

The world is coming to an end. The question raised is how or when. We already know that in a few billion years the Sun will expand and engulf our planet as it consumes its remaining supply of fuel. Planet Earth has gone through five mass extinctions over the course of 4.5 billion years, possibly leading to a new mass extinction which would be a product of our own design through human based global warming or nuclear annihilation. Over the past fifty years the median global temperature has elevated at the fastest rate in history, meaning that sea levels will […]

Air pollutants is a matter in the air that can have animpact on human health and ecosystem. Air pollution contains substance likecarbon dioxide, sulphur oxides, nitrogen oxides, carbon monoxide,chlorofluorocarbons and many more. Therefore, it has impact on human healthespecially on the cardio-respiratory system. People with early respiratoryconditions, such as asthma and allergies, are especially vulnerable to airpollutants. The effects on human health can include reduced lung function,heart disease, stroke, respiratory illnesses, and lung cancer. In economicterms, health impacts are hard to quantify, but studies suggest they may besubstantial. According to the news from The Star over the period between 2005and […]

Impact of Transit on Human HealthIntroductionTransportation plays a vital rolein promoting economic growth and development of any city. Due to increase inpopulation, because of both natural causes and migration from smaller cities tourban cities, the transportation demand rises significantly. Availability of motorizedvehicles increases household income, increase in commercial as well asindustrial activities, which further adds to transport demand. Public transportis critical urban infrastructure providing affordable energy efficient andconvenient transportation to city dwellers (Gershon et al., 2013). But transportation is one ofthe major causes of air pollution. Vehicles emit particulate matter and othergases which deteriorates air quality which can cause respiratory […]

Plastic has been said that Americans throw away 35 billion plastic bottles and other plastic items each year. Almost every hour nearly 250000 plastic bottles are dumped and it is not surprising that plastic bottles constitute close to 50% of recyclable waste in the dumps.The average time taken by plastic bottles to decompose in a landfill is close to 700 years. Plastic not only adds to landfills and takes forever to decompose. The problem is so significant with so many plastic bottles and other kinds of plastics being thrown everywhere and it is causing enormous plastic pollution. There has been […]
