Learn the basics about different types of chemical industries, from agriculture to pharmaceutical to energy, and many other uses. In this video, we consider the environmental impact caused by a range of different types of chemical...

In 1958, after receiving a letter describing the deaths of songbirds due to the pesticide known as DDT, Rachel Carson began an investigation into the misuse of chemicals and their toll on nature. In 1962, she published her findings in...

As populations have grown, farming practices have become more intensified to maximise crop yields and ensure we can feed the ever growing population. Fertilisers and pesticides are used on crops, and animals may be kept inside in more...

This video discusses the significant sources of pollution in our oceans, focusing on the impact of chemical waste and plastic pollution. It highlights the consequences of pollution on marine life, human health, and the environment. The...

This video is answering the question of is chemical energy harmful to the environment.

Toxic "forever chemicals" called PFAS have been found in water, food, and even our blood, causing serious health problems like cancer and birth defects. These chemicals don’t break down and have spread across the U.S. through products,...

Conventional pesticides are a double-edged sword that scientists are now seeking to replace with more natural RNA-based plant vaccines. The U.S. Department of Agriculture estimates that without pesticides, roughly 70 percent of the...

In January 2014, thousands of gallons of chemicals, including crude 4-methylcyclohexanemethanol, or MCHM, spilled into West Virginia's Elk River, near Charleston. The spill ultimately contaminated the local water supply and approximately...

How are the manufacture, possession, and transfer of toxic chemicals regulated within the United States?

The vital links between a healthy society and a sustainable environment.

Chemical plants create many of the materials found in everyday items, from the shoes you wear to the car you drive to the cell phone in your pocket. But the massive carbon footprint from chemical manufacturing is leading to climate...

How do we grow crops quickly enough to feed the Earth's billions? It's called the Haber process, which turns the nitrogen in the air into ammonia, easily converted in soil to the nitrate plants need to survive. Though it has increased...

We now know about physical and chemical weathering, so now it's time to learn about the different weathering environments. These are fluvial, aeolian, and glacial. Let's start with fluvial, which means environments dominated by flowing...

Nitrogen makes up 78% of the air, however neither plants nor animals can take nitrogen directly from the air because nitrogen is so unreactive. The nitrogen cycles shows the movement of nitrogen through the environment. Nitrogen is...

What's it really like to be a chemical engineer? What does a chemical engineer do all day? Anita Kalathil shows us some of the latest chemistry projects taking place at Proctor & Gamble and what her typical day is like inside and outside...

In Middleton, Wisconsin, a small business is expanding on ways to make everything from biopesticides to vaccines – all on the surface of leaves! How does this innovative approach to chemical manufacturing help us use the greenest, most...

From cleaning supplies to pharmaceuticals, surfactants are the compounds that make your soap bubbly, your paint spread smoothly and your medication dissolve more easily. Surfactants can be found everywhere because of their unique...

In this video, the teacher explains the essential element of ice ages - ice. They discuss how water transforms into ice at its freezing point when enough heat is removed, causing molecules to form a rigid pattern and create a solid...

Energy is like the bestest best friend ever and yet, most of the time we take it for granted. Hank feels bad for our friend and wants us to learn more about it so that we can understand what it's trying to tell us - like...

The path that products take to get onto store shelves doesn’t always leave the best impact on the environment. But with green chemistry, chemists have found ways to make the production of some items safer for both people and the planet.

Hank talks about the last major way humans are impacting the environment in this penultimate episode of Crash Course Ecology. Pollution takes many forms - from the simplest piece of litter to the more complex endocrine distruptors - and...

As organisms decompose their chemical and bacterial components can leach into the surrounding ground and water. The bodies buried in cemeteries are no exception.

Let's face it: Humans are pretty messy. Industrial processes like mining and manufacturing are important parts of keeping civilization going, but they all impact the environment. Sometimes that impact is particularly big and messy,...
