We know that microplastics have found their way into our food chain. Understanding the sources of microplastics, their journey to our plates, and what we can do to reduce the risks is essential for tackling this pressing issue.

Sisters Against Plastic (Mary and Theresa) are ‘normal people’ who noticed just how much plastic they were using.

If we don't grasp why ecosystems function, it becomes harder to determine possible reasons for when they don't, and makes it difficult to identify possible environmental threats to humans. In this free course, Introduction to ecosystems, you will discover how organisms are linked together by complex interrelationships, how such links are studied...

This free course, Eating for the environment, will explore the links between food, nutrition and environmental sustainability.

What is ecology and why is it important to our understanding of the world around us? This free course, Introducing the environment: Ecology and ecosystems, looks at how we can study ecosystems to explore the effect that humans are having on the environment.

Why do butterflies matter? Willow Neal explains why they should be prioritised for conservation and introduces us to some butterfly species in the UK.

The total area of garden space in the UK is probably greater than that of all the nation's nature reserves. Converting just a small section of your garden into a breeding place for birds can make a small but significant contribution to the survival of bird species.

Environment: treading lightly on the Earth focuses on the problem of greenhouse gas emissions, especially carbon dioxide. This free course will give you an understanding of the nature and importance of carbon footprints of individuals and households. It will enable you to measure your own carbon footprint and explore what you could do to reduce ...

This course explores the role of fire as a natural disturbance in ecosystems. It introduces the concept of a fire regime and its influence on the type and distribution of organisms that occur in fire prone ecosystems. It also looks at some of the adaptations of plants that have evolved in these ecosystems and how animals either avoid or exploit ...

There is a fascinating world of nature all around us which we can see if we know how to look for it. Wherever you live, be it in a city or the countryside, you will find areas that support a range of wildlife. This free course, Neighbourhood nature, will provide you with basic scientific and observational skills so that you can go into your ...

This free course introduces the emerging field of Climate Psychology. It is now widely accepted that facts about climate change, taken alone, do not promote change. There is growing recognition that deeper psychological perspectives, beyond traditional psychological approaches, could enrich environment movements. Additionally, evidence is ...

How do we feed a growing global population? James McCarron compares the production of mycoprotein to meat. With significantly less impact on the environment than meat, does mycoprotein deserve more recognition?

Discover why research into sustainable chemistry is vital to reduce both the use of resources and the environmental impact of society on the planet.

This free course, Climate justice for the next generation, frames global warming and climate change in terms of social justice, human rights and intergenerational equality and emphasises how children and those least responsible for climate change are the ones who suffer its most significant consequences. The course looks at the impact ...

Climate crisis is one of the grand challenges we face as a society, but it can be hard to approach as a subject. Not only can the science at times seem dauntingly complex, but the solutions are also far from clear. This leaves many people feeling confused, guilty, anxious, angry, or else completely switched off from the subject. This course ...
