Forests are cut down!!Biodiversity

loss!! Species Extinction!! Development of land for new housing or

industry land is one of the many ways in which

habitat is altered or destroyed.

So, what can we do????So, what can we do????

Biodiversity conservation efforts

Protect and restore forest and biodiversity

Most conservation efforts and laws so far havefocused on threatened and endangeredspecies.

The U.S Endangered Species Act had beeneffective but controversial.

Increasingly, landscape level conservation isbeing pursued.

Community based conservation

Solution to depletion of fresh water:

Water, water everywhere, nor any drop to

drink.

--PoemThe rime of the ancient Mariner


8/20

Industry and municipalities can take

water-saving steps.. Recycling municipal wastewater for irrigation

and industrial use.

Capturing excess surface runoff during therainy seasons and pumped it into aquifers.


9/20

Toxics chemicals

Our waterways have become polluted with

toxic organic substances of our own making,

include petroleum products, and other

synthetic chemicals.

Poison animals and plants alter aquatic

ecosystems and cause wide array of human

health problems


10/20

legislating and enforcing more

stringent regulations of industry Help reduce releases of these toxic inorganis

chemicals

Federal Water Pollution Control Act 1972


11/20

Marine conservation

Marine pollution threaten resource

Nets and plastic debris endanger marine life

1. Plastics bags and bottles, gloves, floats,abandoned cargo

2. Marine mammals, seabirds, sea turtles

mistake floating plastic debrics for food and

can die of result ingesting material that they

cannot digest


12/20

Oil pollution comes from spills of all

sizes Minimizing the amount of oil we release into

coastal waters is important, becausepetroleum pollution is detrimental to marine

life So, government worldwide have begun to

implement more stringent safety standards fortankers

The U.S Oil Pollution Act Of 1990-$1 billion-cleanup fund

Air pollution:

Clean Air Act 1990

EPA(Environmental Protection Agency)

Sets air quality standards for criteria pollutants1. Carbon dioxide

2. Sulfur dioxide

3. Nitrogen dioxide

4. Particular matter

5. lead

Global climate change

Carbon dioxide is the greenhouse gas of

primary concern

Temperature increases will increase Rising sea levels will affect hundreds of

millions of ppl


15/20

Responding to climate change:

Conservation and effiency Conserving electricity, improving effiency of

energy use, and switching to clean and

renewable energy-help reduce fossil fuel

consumption and greenhouse emissions.


16/20

Conventional Alternatives VS

renewable energy Nuclear power, biomass energy and

hydropower are conventional alternatives


17/20

Biomass energy:

New biomass strategies are being developed

in industrialized countries

Biofuels can power automobiles Biomass energy brings environmental and

economic benefits

Biomass energy also brings drawbacks


18/20

Hydroelectric power:

Widely used

Clean and renewable
