Презентация на тему Ecological Problems

of living organisms to each other and their surroundings.
Ecology

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

What is the Ecology???

Urban development
• Global warming
• Genetically modified foods
• Toxic waste
•

Solar and wind power
• Recycling scheme

substances intended for preventing, destroying, repelling or mitigating any

pest.

Overuse of pesticides

A pesticide may be a chemical substance, biological agent (such as a virus or bacterium), antimicrobial, disinfectant or device used against any pest.

statistical distribution of weather patterns over periods of time

that range from decades to millions of years.
It may be a change in the average weather conditions or a change in the distribution of weather events with respect to an average, for example, greater or fewer extreme weather events.
Climate change may be limited to a specific region, or may occur across the whole Earth.

Climate Change

planning and transportation planning to improve the built, economic

and social environments of communities.
Regional planning deals with a still larger environment, at a less detailed level.

Urban planning can include urban renewal, by adapting urban planning methods to existing cities suffering from decay and lack of investment

Urban development

temperature of Earth's near-surface air and oceans since the

mid-20th century and its projected continuation.

Global Warming

genetically modified organisms. Genetically modified organisms have had specific

changes introduced into their DNA by genetic engineering techniques.
These techniques are much more precise than mutagenesis (mutation breeding) where an organism is exposed to radiation or chemicals to create a non-specific but stable change.

Genetically modified foods

electricity, either directly using photovoltaics (PV), or indirectly using

concentrated solar power (CSP).

Solar Power

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.

Wind Power

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.
