Knowledge and skills developed in this chapter, according to the official bulletin (official curriculum) 📖: Biodiversity changes over time. Biodiversity evolves constantly. This evolution is observable on short time scales, both at the genetic and specific levels. The study of past biodiversity through the examination of fossils shows that the current state of biodiversity corresponds to a stage in the history of life. Thus, the current living organisms represent only an infinitesimal part of the organisms that have existed since the beginning of life. Biological crises are an example of a major modification of biodiversity (massive extinctions followed by diversification). Many factors, including human activity, cause modifications of biodiversity.

On this principle, each user can choose to pay the advertising revenue from their searches on Youcare (it is therefore free for the user) to the association or content creator of their choice. For 2 years, the objective of my work under the name of Madame SVT 🐸 is to make accessible to everyone and everyone knowledge always of my discipline that are the Sciences of Life and the Earth 🌏. It is therefore with immense pride that I announce that I have been chosen by Youcare to be one of their first partners as a content creator in the category "Sharing knowledge and knowledge" 😍! This means that today, you can also help me develop my channel by simply using this search engine rather than another, and that, with your searches, Youcare will give me a share of its profits so that I can develop my project further, buy equipment to improve my YouTube channel 🎥 and make my videos even more accessible to everyone! You therefore have an excellent, simple and free way to support my work, if you wish 😊 This search engine can be used on 💻, tablet or 📱 and, to configure it directly under my profile, you can use this link: https://bit.ly/2UihjCD! Thank you in advance to everyone ❤️ Small details: Youcare respects your privacy , by never recording your searches, and also respects the environment, by compensating for their CO2 emissions through a global reforestation program 🌏🌳
