Each species, be it plant, animal or microbial, has its own habitat and, through various trophic and non-trophic relations, it is part of an ecosystem. When it reaches a different ecosystem, it can adapt or not. If it adapts, it can cause lots of trouble, since native species are, often, incapable of adapting to the invader.

Biodiversity simply means all the living beings that are currently found on our planet. There are countless millions of microbial, plant and animal species, and us, humans, being one of its most important components. Each species has from a few dozens to billions of individuals.

We are all talking, nowadays, about biodiversity and climate change, and there are many international conventions regarding the two of them. Most people acknowledge that we are undergoing a period of climate changes, and that is, at least partially, imputable to our industrial activities.

When you want to find high biodiversity, the first idea that crosses your mind would probably be to go to a tropical rainforest. Do not bother! Just take some mud from the nearest pond or lake!

Human activities have many negative effects on the environment and one of the most obvious is threatening biodiversity. Species go extinct, or are on the verge of extinction, due to reckless hunting, fishing, habitat destruction, pollution, climate changes and so on. What can be done to stop this trend?
