PROBLEMS
POLLUTION
WASTES
Household wastes/ sewage
Industrial pollutants/ waste
dump into
toxic substances
non-biodegradable
Industrial zones
to discharge chemical waste
water quality deterioration
water-borne diseases
to affect aquatic ecosystems
AIR
GLOBAL WARMING
CAUSES
Industrial zones/ manufactures
emissions
a results of burning fossil fuels: coal, oil, gasonline
run out
Private vehicles
to emit exhaust fumes
CO2 - carbon dioxide
Greenhouse gases
deforestation
to deplete natural resources
CO2
Bao quanh trái đất là bầu khí quyển(Ozone layer) có khả năng hấp thụ và phản xạ lại bức xạ của mắt trời(sunbeam), nhưng CO2 làm thủng tầng Ozon(Ozone layer depletion), khiến bức xạ chiếu trực tiếp tạo ra nhiệt độ trái đất tăng
to trap heat from the sun
to increase temperature
global warming
greenhouse effects
climate changes
EFFECT
melting of icebergs/ glaciers
rise of sea level
habitat destruction
endangered/ vulnerable species
species losses
change of weather patterns
natural disasters
hurricanes
drought
wildfire
ENERGY CRISIS
WATER SHORTAGE
NATURAL DISASTER
NOISES
GENERAL REASONS
Population growth
put pressure on natural resources
Industrial development
long-term human activities
GENERAL SOLUTIONS
GOVERNMENT
Global cooperations
reach the agreement
make laws
limit emissions from factories
encourage low-carbon economy
exploit renewable from solar, wind or water power
invest in energy-saving technologies
lead green consuming habits
raise public's green awareness
impose "green taxes" on drives and airlines companies
promote recycling
take effective measures to eliminate the toxic fumes released into the atmosphere by the disposal of waste, especially plastic.
all companies used biodegradable plastic for their products
use the media in order to raise public awareness in relation to recycling.
create laws to combat the problem of the disposal of waste and ensure that people abide by these laws through regular inspections
If governments don’t tackle this issue immediately, the consequences are going to be catastrophic in the long run.
It is imperative that the issue of waste is addressed so as to reduce the risk to people’s health due to potential health hazards.
set international standards for environmental protection
INDIVIDUALS
choose product with less packaging
recycle as much as possible
take public transport rather than driving
CYCLING
GENERAL EFFECTS
destroy wildlife habitats
cut down enormous areas of rainforest
led to extinction of many species of animals and plants
NUCLEAR POWER
WHY?
fossil fuel are running out
BENEFITS
sustainable energy source
use to produce electricity without wasting natural resources
replace the use of natural resources
nuclear power stations are clearner than fossil fuel power stations
reduce carbon emissions that cause global warming
DRAWBACKS
the safety of power stations
the building of new nuclear power stations is unpopular
nobody wants to live near one
nuclear waste disposal is a significant problem
no way to decontaminate radioactive material
terrorists could steal radioactive materials
It is safer to produce energy from solar, wind or water power
NATURAL RESOURCES
Trees play a vital role to people’s health and well-being
Not only do they provide oxygen and improve air quality but they also make the surroundings beautiful
the only solution to the problem of deforestation is reforestation
There is a tendency towards the overconsumption of the earth’s resources whereas governments should focus on ways to make the most of natural energies that don’t run out.
There is the opportunity to produce electricity naturally by converting the energy of the sun (solar energy into electricity).
Governments should take decisive action in order to tackle the problem of ecologically wasteful products; this toxic trend, which is the result of consumerism, will ultimately lead to an environmental disaster.
