Environmental Biology

Front 1

what should each society’s goal be?

Back 1

"to maintain an environmentally sustainable society."

Front 2

what are the basic needs often thought of as?

Back 2

food, clothing, clean water, shelter, and space. Economists often add: "Enough income to meet the basic needs plus:"
-A respectable and safe work environment

- Health care

- Recreation

-Cultural opportunities

- Education

-Freedom from physical danger, such as public services, law enforcement, and streetlights, etc.

Front 3

Define environmentally sustainable society?

Back 3

It satisfies the basic needs of its people, without depleting or degrading its natural resources, and thereby preventing current and future generations from meeting their basic needs.

Front 4

Define sustainable?

Back 4

"to support, to bear, to endure without giving way or yielding." It infers that our use of natural resources does not, or should not, exceed or is at least no greater than their rate of replenishment or renewal.

Front 5

what is the 6 environmental issues?

Back 5

-Human population growth

- Wasteful and unsustainable resource use

- Failure to include the harmful environmental costs of goods and services in their market prices

- Insufficient knowledge of how nature works

- Poverty

Front 6

Define Pollution?

Back 6

as any addition to air, water, soil, or food that threatens the health, survival, or activities of humans or other living organisms.

Front 7

"Is our present course sustainable?"

Back 7

I think that right now were doing ok, but not for long. If we don't keep doing are best to recycle and save water and electricity, we might not have any resourses left. Theirs already organizations around that are about saving the planet. Solar energy is one them and natural gas is another made by bio-mass. So if we all do our part on saving our natural resourses, not polluting and recycling we should be ok for along time.

Front 8

what are Natural resources?

Back 8

perpetual-Perpetual resources are not affected by human use of them. Examples are sunlight and wind.

renewable-are ones that can be replenished or reproduced easily. Some of them, like sunlight, air, wind, etc., are continuously available and their quantity is not affected by human consumption. Many renewable resources can be depleted by human use, but may also be replenished, thus maintaining a flow. Some of these, like agricultural crops, take a short time for renewal; others, like water, take a comparatively longer time, while still others, like forests, take even longer.

non-renewable - are formed over very long geological periods. Minerals and fossil fuels are included in this category. Since their rate of formation is extremely slow, they cannot be replenished once they get depleted. Of these, the metallic minerals can be re-used by recycling them. But coal and petroleum cannot be recycled.
