Global warming is the ongoing rise of the average temperature of the Earth's climate system which has various negative effects.
Overpopulation creates an increased demand for energy as well as having negative effects on our environment and ecosystems.
Water is essential for agricultural production and food security. It is the lifeblood of ecosystems, including forests, lakes, and wetlands.
Overpopulation affects our water and this has negative outcomes.
Over-cultivation is the practice of excessive farming on a piece of land to the point of degradation of the soil as well as the land itself.
Climate change is likely to both increase electricity demand for cooling in the summer and decrease electricity, natural gas, heating oil, and wood demand for heating in the winter.
Finding reusable energy sources can be our first step towards conserving our environment.
New infrastructure investments may be necessary to meet increased energy demand.
e.g.: nuclear power plants
Healthy ecosystems and rich biodiversity are fundamental to life on our planet.
Even small changes in average temperatures can have a significant effect upon ecosystems.
Зі знаходженням суми членів арифметичної прогресії пов’язана така цікава історія. Відомий німецький математик Карл Гаусс (1777 - 1875) ще у школі виявив блискучі математичні здібності. Якось учитель запропонував учням знайти суму перших ста натуральних чисел.
Маленький Гаусс розв’язав цю задачу за хвилину. Зміркувавши, що суми 1+100, 2+99 і т. д. рівні, він помножив 101 на 50, тобто число таких сум. Інакше кажучи, він помітив закономірність, яка властива арифметичній прогресії.
Climate change will affect mountain and lowland ecosystems, the diversity of wildlife, and the distribution of freshwater.
e.g.: forest fires
Архімед вперше зіставляє арифметичну та геометричну прогресії і вказує на зв’язок між ними.
Греки розглядали прогресії як продовження пропорцій, тому епітети арифметична та геометрична були перенесені від пропорцій на прогресії.
Саме такий погляд на прогресії зберігся і у багатьох математиків XVII i XVIII ст.
Climate change is affecting the habitats of several species, which must either adapt or migrate to areas with more favorable conditions.
e.g.: natural habitat disappearing
Climate change is supported by scientific evidence.
Write down the consequences caused by the melting of the ice-caps and how it will affect our lives and the environment in the future.
e.g.: decreasing of polar bear habitat
Write down the consequences caused by this issue and how it will affect our lives and the environment in the future.
e.g.: decreasing of land surface
