Презентация по английскому языку на тему: "Экологические проблемы"

What is the Ecology???

Ecology is the scientific study of the relation of living organisms to each other and their surroundings.

Ecology includes the study of plant and animal populations, plant and animal communities and ecosystems.

Ecological problems are:

• water pollution
• air pollution
• greenhouse effect
• ozone lay(holes)
• deforestation

destruction of wildlife and the beauty of the countryside

Global warming is the increase in the average temperature of Earth's near-surface air and oceans since the mid-20th century and its projected continuation.

Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP).

Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electricity, wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships.

Recycling involves processing used materials (waste) into new products to prevent waste of potentially useful materials, reduce the consumption of fresh raw materials, reduce energy usage, reduce air pollution (from incineration) and water pollution (from landfilling) by reducing the need for "conventional" waste disposal, and lower greenhouse gas emissions as compared to virgin production .
